EMR operating temperature
The EMR enclosure meets all specifications over a 41°F to 104°F (5°C to 40°C)
ambient temperature range with a maximum temperature gradient of 36°F
(20°C) per hour. The enclosure should be located such that the ambient
temperature at the front and rear of the unit is not exceeded. Air flow may be
needed to achieve these temperatures. Continual or sustained operation at
temperatures above these values may degrade MTBF. Operation of the EMR
enclosure at the maximum temperature is intended for short time periods only.
Continuous operation at the elevated temperatures will reduce product
reliability.
Relative humidity
The values below assume that no condensation on the EMR enclosure occurs.
•
Operating: 8% to 90% relative humidity with a maximum gradient of 30% per
hour.
•
Non-operating: 5% to 95% relative humidity.

SkyStream Networks
SkyStream EMR™
MPEG-2 (Motion Pictures Experts
Group) A group of standards that
specify an encoding and
compression process. An MPEG2 system provides a method for
combining (multiplexing) several
types of multimedia information
into one stream.
The SkyStream Edge Media Router (EMR) is a powerful platform to receive and
manage Internet content at the network edge— empowering service providers
and enterprises to deliver rich content to large communities of users via
broadcast and broadband networks. The SkyStream EMR receives MPEG-2
transport stream containing IP traffic, decapsulates this IP traffic and forwards
it over a pair of 10/100 Ethernet ports. Each port is capable of forwarding
packets up to 100 Mbps. The EMR supports both unicast and multicast traffic.
IP (Internet Protocol) A
connectionless protocol that
provides packet routing.
Multicasting One-to-many
transmission of an IP datagram to a
host group—a set of one or more
hosts identified by a single IP
multicast destination address. A
multicast datagram is delivered to all
members of a destination host group
with the same reliability as unicast IP
datagrams.

Overview
EMR-5000 User’s Guide version 2.3
Operating
Procedures
The following is a short review of how the satellite receiver and its related
components route data through the system.
Frequency Translation Basics
Sending data such as audio, video, and digital data, from one location to another
often requires rearranging it in a variety of ways. The sender packs up the
information, and the receiver unpacks it when received. The signal is sent via
satellite where the satellite dish receives the signal. In order for the signal be
delivered to the receiver, the signal must be down converted (modified) to be
carried over coaxial cable.
Satellite signals, coming from space use higher carrier frequencies than television
broadcast frequencies. Large dish antennas use signals in the C frequency band
(3 to 5 GHz) and the current popular consumer small dish antennas use signals
in the Ku frequency band (10 to 13 GHz). These carrier frequencies are too high
to be used on the coaxial cable that connects the antenna to the receiver.
To rectify this problem, the antenna system down converts the carrier frequency
value to the range between 950 and 2150 MHz, which is consistent with the
coaxial cable transmission requirements.
Many satellite frequencies are available, and the same receiver might be used to
cover a wide range of frequencies. For example, you may need to receive a signal
range of 10.90 to 13.25 GHz. This is a range larger than the satellite receiver is
able to support.
LNB (Low Noise Block) A
combination Low Noise Amplifier
and downconverter built into one
device attached to the feed.
Using a dual-range LNB antenna is one solution to this problem. Each LNB uses
a different frequency range. Each LNB monitors either the low or the high part
of the frequency range. The satellite receiver must be able to switch the LNB
settings from one to the other in order to work with this type of system.

SkyStream Networks
Standard Features
TTL (Time To Live) This value
decrements each time the IP
frame moves through a router.
When the number reaches the
value of zero, the stream is
discarded.
IGMP (Internet Group
Management Protocol) A control
protocol used by multicastenabled hosts to report their group
membership information to
directly-attached routers.
OS (Operating System) The
master control program that runs
the computer. The operating
system is the first program loaded
when the computer is turned on,
and its main part, called the
“kernel,” resides in memory at all
times.
SNMP (Simple Network
Management Protocol) A
standard protocol to manage
devices in the network.
Manageable devices contain an
SNMP Agent responsible for
handling the information control
request.
Easy Management of Data Routing to the Local Area Network
Data coming into the network via multicast streams are easily routed to a
network or server. Administration for incoming streams including IP address
and Time-To-Live (TTL) modification provide easy configuration for various
LAN environments.
IGMP Service
The IGMP service is an integrated option included in the SkyStream EMR. Only
data that is requested by the clients on the LAN is forwarded to the listeners.
IGMP automatically detects when requests are made on the network where the
user application supports IGMP. In addition, the system administrator is able to
configure rules for each incoming multicast stream.
Recovery Features
Many levels of technology have been included to ensure configuration integrity
during the initial and re-boot sequences due to power failure or network
problems. With solid-state memory, a protected OS file system, and stored
configuration data, the SkyStream EMR has administrator-free recovery features.
Monitoring
The SkyStream EMR provides monitoring and diagnostic functionality for
safeguarding data integrity.
Online Management
Configuration of the SkyStream EMR is handled online using either a command
line interface (CLI) or a Web GUI. In this way, all satellite tuning, data handling,
and IP routing functions can be controlled and managed remotely via the local
area network (LAN). In addition, the EMR supports SNMP management, using
third party applications such as HP OpenView.
Turbo Internet/VPN
SkyStream’s Turbo Internet solution employs an asymmetrical satellite network
that provides a high-speed delivery system. Turbo Internet uses the EMR, in an
end-to-end broadband content delivery system that includes an IP encapsulator,
such as the SkyStream satellite Source Media™ Router (SMR). Most Internet
traffic is asymmetrical in nature. There is much more data going toward the
Internet terminal than away from it. The Turbo Internet takes advantage of this
fact and employs a high-capacity forward path and a lower-capacity return path,
such as ISDN or modem. SkyStream’s solution also incorporates Virtual Private
Networking (VPN), which emulates point-to-point connectivity. For a secure
VPN, data is encrypted using a protocol called the Point-to-Point Tunneling
Protocol (PPTP), or IPSec.

Overview
EMR-5000 User’s Guide version 2.3
SkyNAT
SkyNAT is the SkyStream EMR application used to support packet translation
of incoming data from satellite for address translation, protocol translation, and
TTL translation.
The objective of packet translation in an Edge Media Router is to modify IP
packets received from the satellite interface prior to sending them on to the
Ethernet interface. The following types of translations are possible:
■
■
■
■
IP address translation: Modify the destination address of the received packet
prior to sending it out.
Protocol translation: Transfer the payload of the packet from one protocol to
another.
Port translation: Modify the destination and/or source port of a packet; these
translations are protocol-dependent.
Other translations: Modify other fields in the IP header, such as the Time-ToLive (TTL) field.
The EMR suppor ts address translation, protocol translation, and TTL
translation.
Address Translation
Address translation means replacing the received destination IP address, in the
packet received from the satellite interface, with a different IP address prior to
sending it out over the Ethernet interface.
Protocol Translation
Protocol translation is the process of receiving data payloads in one protocol,
and then re-transmitting these payloads in another protocol. The most common
layer-4 data transfer protocols in use are TCP and UDP.
UDP to TCP
UDP (User Datagram Protocol) A
connectionless transport-level
protocol used in the suite of IPbased protocols.
TCP (Transmission Control
Protocol) The connectionoriented, transport-level protocol
used in the suite of IP-based
protocols.
The EMR is capable of converting UDP from the DVB link into TCP in the
local area network to reliably deliver the payload. Of course, appropriate client
software applications are required to take advantage of this, since packet
boundaries are lost in the conversion from UDP to TCP.
On the TCP side of the connection, the EMR will listen on a TCP port and wait
for clients to connect (i.e., it will act as a server).
The EMR supports multiple clients on the same stream, with a set maximum of
five clients. The EMR will manage each connection independently. This allows
for point-to-multipoint support.
SkyCast
SkyCast is the SkyStream EMR system used for IP Multicast Management. The
user has the option to enable or disable SkyCast; however, the default rule will
continue to be processed.
5
SkyStream Networks
Rules for Multicast Packet Processing
From a rule structure created by the user, the EMR will read the initial startup
value of the default processing. If no session file exists or if a default processing
is not set in the session file, the EMR will still forward the stream to a listener.
This is one of the purposes of having SkyCast enabled.
The default rule’s IP address and Netmask are as follows:
1 IP Address:
224.0.0.0
2 Netmask:
240.0.0.0
3 TTL:
0
This r ule instr ucts the EMR to forward all multicast addresses (address
224.0.0.0, mask 240.0.0.0) without changing the TTL (indicated by the value 0).
Each rule can take the following actions:
Forward-if-listener
For the default processing to be forwarded-if-listener, the user must enable
SkyCast.
The forwarding rule is as follows:
Multicast packets will only be forwarded into the local Ethernet port(s) if hosts
in the attached network have joined the group.
Forward
The selection of this option implies that the user wants to always forward
packets to the local Ethernet ports. The user adds rules for forwarding packets
via the following two mechanisms:
■
Unicast to Multicast
■
Multicast to Multicast
To accomplish this, the user must specify the destination Ethernet interface
through which the packet will be forwarded.
Discard
The EMR will discard the packets with the specified destination address.

Optional Features
ISDN
HDLC (High-level Data Link
Control) An ISO communications
protocol used in X.25 packet
switching networks. It provides
error correction at the data link
layer.
Bit stuffing Adding bits to a
transmitted message in order to
round out a fixed frame.
VSAT (Very Small Aperture
satellite Terminal) A small earth
station for satellite transmission
that handles up to 56 kbits/sec of
digital transmission.
Integrated Service Digital Network (ISDN) has an optional connection in the
expansion slot at the back of the EMR that is configurable via the Web GUI or
CLI commands. ISDN allows data to be transmitted from point-to-point and
reach a destination without errors. The rate of transmission of the data in the
ISDN is 64 kbps per channel.
NOTE Two channels are supported in this release.
Sync Transmission Interface
The EMR has a Sync-In port option through an expansion slot at the back of the
unit and configurable via the Web GUI or CLI commands. The Sync-In port can
receive streams of synchronous data from an SMR or IP encapsulator. After
receiving HDLC frames with bit stuffing via satellite, the SMR packetizes the
frames using the Data Pipe packetizer and sends them on to the EMR. The EMR
then forwards the MPEG-2 Transport Stream through a Sync card to a Sync
Receiver.
Internal Modem
The EMR has optional internal modem in the expansion slot at the back of the
unit. You can select this option in Configuration PPP, Hardware Settings.
TCP Acceleration
TCP Acceleration optimizes the use of TCP over satellite. This feature
overcomes the resource consumption problems normally associated with
Internet/Intranet applications in a satellite environment. TCP Acceleration
supports both passive and active FTP, concurrent TCP connections, VSAT, and
redundancy backup.

First Time Logon
Accessing the SkyStream EMR happens in one of two ways. You
can use either a command-line interface (CLI) or a Web GUI. In
addition, you can access the CLI either through the serial port or
through telnet via the Ethernet interface. The web interface is
accessed via the Ethernet. The following sections walk you
through the logon processes for the CLI or Web GUIs.
CLI Login
If an Ethernet or a Web GUI connection is not available, you can
configure the SkyStream EMR with the Command Line Interface
(CLI) using the serial port connection, this is reviewed in “Basic
Connections.”
Security
There are two levels of security/authentication in the EMR:
TIP SkyStream recommends that

Chapter 4: CLI Commands and Operation
27
SkyStream Networks
Command Line Interface
CLI Basics
This chapter covers the basic operation and commands of the Command Line
Interface (CLI). After reading this chapter, you will be able use the CLI to
configure and manage the EMR.
You can access the SkyStream EMR’s command line interface through a Telnet
or console (serial port) connection. Accessing the command line interface is
referred to as a CLI session.
When you establish a CLI session, commands within the EMR’s CLI are in a tree
structure. To configure the EMR, you need to understand how to navigate the
CLI tree structure. The following section walks you through navigating within
the CLI tree. With the help of the question mark (?) and “Show” functions, you
will learn how to determine where you are in the tree, and what functions and
subcommands are available.
Depending on the position within the tree structure, you will have access to
different command options. Once in a given configuration branch, you may
enter the system level configuration commands that apply to that particular
level. In addition, the command prompt changes to reflect the position within
the tree structure to assists with navigation. This allows for easy reference within
the tree structure when in configuration mode.
To start a CLI session, see Chapter 3, “CLI Login.”
To list the main nodes available at the CLI level, type a question mark (?) at the
prompt and hit Enter.
Typing “?” at the prompt will display the following commands: show, no,
ifconfig, netstat, ping, reboot, route, passwd, config, maintenance, diag, and
stats.
When you combine “show” with the question mark (?), the system displays all
the subcommands that you can view. For example, when you type “Show clitree,” the system displays all nodes, subcommands, and functions of the “clitree.”
Type “show cli-tree” to display the CLI tree structure:
This command will display all the root nodes and root subcommands of “clitree” (see Command Definitions).
You can use the “?” with “show” subcommands when there are functions below
the subcommands at this level; for example, “show interface ?”. This will display
the interfaces available.
NOTE Type a space between “show” and “?.”
28
CLI Commands and Operation
EMR-5000 User’s Guide version 2.3
Navigation in
config-mode
The CLI has a special configuration mode, which allows you to configure
individual subsystems. By typing “config” at the prompt, you will enter
configuration mode. The prompt will then change to:
[config-mode]#
To review what functions are available, enter a question mark (?) at the prompt.
Type “?” at the [config-mode]# prompt:
The following functions will display: pref, interface, active_macs1, active_pids1,
active_fkcas1, skycast, skycast_rule, skynat1, snmp, tcpX, and turbointernetvpn.
At the [config-mode]# prompt, enter the next node you wish to access; for
example, when you enter interface, the command prompt changes to [configmode interface]#. To access the nodes at the next level, enter a question mark
(?) at the prompt.
Type “?” at the [config-mode interface]# prompt:
Displays the following interfaces: satrx1, eth1, eth2, ppp, isdn (optional) and
sync (optional).
At the [config-mode interface]# prompt, enter the next node you wish to
access. For example, when you enter satrx1 {, the command prompt changes to
[config-mode interface satrx1]#. To display the options at the next level, enter
question mark (?) at the prompt.
NOTE The user must type “{” after the node to configure. If not, CLI will return
“{ <CR>” meaning that the user must type “{“ followed by a carriage return
(Enter).
Type “?” at the [config-mode interface satrx1]# prompt:
The satellite-configuration option list appears, which shows all the configurable
options available on the interface (see Command Definitions).
Configuration
Values
TIP When typing commands in CLI,
after a few keystrokes, use the TAB
key to complete a command
automatically.
Each configuration option has a value that you can enter. For example, the “String”
values on the “IfStatus” options allows you to enter a rule. The “IP Address” is
simply the IP address being assigned to the Ethernet connection of the satellite
receiver. The “Integer” value is a number for setting the specific option.
To set the satrx1 to 10 Msymbols, at the prompt, type “symbolrate 10.” It should
look like this:
[config-mode interface satrx1]# symbolrate 10
NOTE To return to [config-mode], type “}” to close the current node or, to go
to the CLI prompt, type “exit.”
Conventions: A convention used throughout this User Guide is the use of
“<>” (greater than and lesser than brackets)—brackets enclose keystroke
instructions. For example: <filename> means, type the name of a file, or <CR>
means, press “Enter” i.e., a Carriage Return.

Home
SkyNAT EMR application used to
support packet translation of
incoming data from satellite for
address translation, protocol
translation, and TTL translation.
The Home page displays a short animation showing the basic flow of data from
the satellite through the EMR to the listeners.
SNMP (Simple Network
Management Protocol) A
standard protocol to manage
devices on the network.
Manageable devices contain an
SNMP Agent responsible for
handling the information/control
request.
The Statistics pages display information about the Satellite Receiver, Network
Interfaces, SkyCast (IGMP), SkyNAT, DHCP Ser ver, PPP, ISDN, TCP
Acceleration, Sync and Turbo Internet/VPN settings.
SkyCast: The SkyStream system
used for IP Multicast
Management.
IGMP (Internet Group
Management Protocol) A control
protocol used to link a “group” of
users to the source of a data
stream.
DHCP (Dynamic Host
Configuration Protocol) Software
that automatically assigns IP
addresses to client stations
logging onto a TCP/IP network. It
eliminates having to manually
assign permanent IP addresses.
DHCP software typically runs in
servers and is also found in
network devices such as ISDN
routers and modem routers that
allow multiple users access to the
Internet.

SkyCast
You can enable or disable SkyCast from the Configuration SkyCast page and
then apply new rules. Moreover, you can enable or disable Global source readdress, which re-addresses the IP address of all packets regardless of group or
address. Click Apply to make effective.
The EMR has the following multicast processing functionality (SkyCast):
•
Forwarding: a particular multicast group may be unconditionally forwarded,
discarded, or conditionally forwarded if listeners are in the network.
•
Remapping: multicast addresses and TTL can be optionally remapped to new
values.
NOTE When remapping a source IP address, not all fields in the SkyCast rule need to be
filled. If the intention is just to remap the Source IP Address then it is only necessary to
enter values in the first three fields—Original Source IP, New Source Dest. IP, and Source
Netmask.
Global Source Re-address
If you enable Global Source Readdress, the source IP address of all packets with
a multicast destination will be remapped to eth0, eth1, or both depending on
whichever one has been a listening member joining the multicast group. In
addition, it will use the SkyCast default rule for TTL and forwarding.
128
Web GUI Configuration
EMR-5000 User’s Guide version 2.3
NOTE If SkyCast is enabled, then the source map will first try to process the
rules in SkyCast and then process global source remapping. If the user only
wants to use the default rule—with global source IP remap enabled—and
bypass the SkyCast rules, then the user can disable SkyCast.
SkyCast Rules
SkyCast Rules allow you to add, edit or delete SkyCast rules from the system.
SkyCast rules also allow you to apply specific guidelines on how the information
is sent to the local network.

SkyStream Networks
TTL (Time To Live) Entering a
new TTL number affects the
number of routers that packets
may be sent through. Every time
a router forwards a packet, it
decrements the TTL by one, if the
TTL reaches zero, the packet is
discarded. The TTL settings can
vary depending on the topology
of the local network to attempt to
keep streams from being
forwarded outside of your
network.
•
Original Source IP Address, New Source IP Address, and Source
Netmask (Optional): These three settings are used to remap the Source IP
address.
•
Original and New Destination IP Addresses: These settings are the
Original Destination IP Address of a data stream to be sent to a New
Destination IP Address.
•
Netmask: The netmask specifies the range of addresses to be translated. For
example, a netmask of 255.255.255.255 represents only one address, while a
netmask of 255.255.255.0 represents a range of 256 addresses. Example: If
Original Dest. IP Address is 224.1.1.0, Netmask is 255.255.255.0 and New
Dest. IP Address is 225.1.1.0, then packets destined to 224.1.1.1 will
translate to 225.1.1.1, packets to 224.1.1.2 translate to 225.1.1.2, and so on up
to 224.1.1.255 translating to 225.1.1.255.
•
TTL (Time To Live) If you leave this value at zero, the TTL remains
unchanged.
NOTE The default for the TTL value is zero (0). This is a special value used to
indicate that the EMR will not change the TTL value as it forwards the
packets. If you leave this value at zero the TTL remains unchanged; however, this only
applies if Router Mode is enabled in Maintenance Preferences.
•
Action: The Action radio buttons allow you to set up a specific Forwarding
Rule for the specified multicast IP address. The following three options are
available:
■
■

•
130
Forward If Listener: Sends the multicast packets from this multicast group into
the network if there is a group member present.
Discard: Discards all packets belonging to this group.
Forward: Sends the Multicast packets into the local network unconditionally;
however, you will need to select which Ethernet to Forward through using the
radio buttons (Ethernet 1, and Ethernet 2).

Click Show debug log at the bottom of the Demand Dialer Rules page and the
following page will appear:
Demand dialer rules
Any default routes must be removed prior to starting demand dialing. When
demand dialing is enabled, the demand dialer installs itself as the default route
and listens for outgoing packets. When an outgoing packet arrives at the default
route, the rules are scanned in priority order; from top to bottom: first “ignore”
and then “accept.” The first matching rule is used. The same rules are used for
both ISDN and PPP.
Demand dialer rules have two actions and these actions apply to whichever
device—dial-up modem (PPP), or ISDN—is configured to “Dial on Demand.”
Only one device may be configured to dial on demand—you cannot enable both
PPP and ISDN at the same time. Changes to any rules will take effect the next
time the modem dials out; they do not affect a current connection. Rules can add
up to a maximum of 40 rules.
ignore
Packets that match an ignore rule will be ignored and will not match any later
rules. Except for the lack of a <timeout> parameter, the parameters are exactly
as described for the accept command.
There is a single timer in the demand dialer, which counts down whenever the
link is connected. When it reaches zero the link is disconnected. Accept rules
can be used to refresh the timer and maintain the link in the connected state.
The ability to define different rules for different types of traffic are very flexible
configuration.
EMR has a default set of rules that may be restored by clicking on the “Restore
factory default rules” button. This set of rules will be sufficient for most users.
These rules may be customized as necessary.
149
SkyStream Networks
accept
Packets that match an accept rule will cause the link to come up and/or stay up
for at least <timeout> seconds. The value <timeout> must be a non-negative
integer. A <timeout> of zero means the connection associated with the packet
will be killed immediately. The default is 300 seconds.
The following debugging method will assist you in the development of custom
rule sets and to diagnose problems with demand-dial connections. The “Show
debug log” button displays a log file that indicates the activity of the demand
dialer. Each time a demand rule causes the EMR to dial out, a “Trigger” message
will appear in the log. This trig ger message indicates the original source,
protocol, source address (and port), and destination address (and port) of the
matching packet that initiated the connection.
Trigger: from locally generated: tcp 192.168.4.178/1044 64. 165.192.147/1723
The above trigger is an example of an EMR initiating a PPTP connection to a
PPTP server at 64.165.192.147, port 1723
The source of the packet that caused the trigger can be one of the following:
locally generated — a packet that originated from EMREMR itself.
eth1 — a packet that was received on Ethernet-1
eth2 — a packet that was received on Ethernet-2
satrx1 — a packet that was received on Satellite Receiver-1
satrx2 — a packet that was received on Satellite Receiver-2
This debug ging message makes it easier for you to know what caused the
modem to dial when configured for demand dialing. This allows you to adjust
demand rules if necessary.
If a timeout expires and causes the disconnection of the link, a message like the
one below will appear in the log:

SkyStream Networks
Turbo Internet/VPN
SkyStream’s Turbo Internet solution employs an asymmetrical satellite network
that provides a high-speed delivery system. Turbo Internet uses the EMR, in an
end-to-end broadband content delivery system that includes an IP encapsulator,
such as the SkyStream satellite Source Media Router (SMR). Most Internet
traffic is asymmetrical in nature. There is much more data going toward the
Internet terminal than away from it. The Turbo Internet takes advantage of this
fact and employs a high-capacity forward path and a lower-capacity return path,
such as ISDN or modem. SkyStream’s solution also incorporates Virtual Private
Networking (VPN), which emulates point-to-point connectivity. For a secure
VPN, data is encrypted using a protocol called the Point-to-Point Tunneling
Protocol (PPTP), or IPSec.
NOTE Demand dialing is not supported when the LAN is the return channel.
To configure the SkyStream EMR for Turbo Internet/VPN, you must enter
connection information into the following tabs:

Click the Manual connect now button at the bottom of the main Turbo
Internet/VPN configuration properties page to immediately try to make a
connection or click Connect on demand to initiate connection through
Demand Rules.
NOTE When PPTP is connected, IPSec is disconnected. Similarly, when
IPSec is connected, PPTP is disconnected.
Manual connect
The EMR will attempt to establish a PPTP or IPSec tunnel with the remote
server as soon as you click Manual Connect (or if the EMR is loaded with a
configuration file that was set for Manual Connect). If the connection attempt
fails, or the remote server is disconnected, EMR will repeatedly try to connect to
the server. You should use this mode should be used if you want the tunnel to
remain up continuously.
Connect on demand
The EMR will establish a connection with the PPTP server or IPSec gateway
only when “interesting” packets arrive. These are packets which match one of
the ACCEPT demand rules, as specified on the Configuration - Turbo Internet
page. If the connection is idle for the specified timeout, EMR will disconnect
from the tunnel server. This feature may be used in conjunction with PPP or
ISDN demand dialing to maintain a tunnel connection only as long as there is a
need.
In the demand case, you can install a route to act as a proxy while the tunnel is
disconnected. For PPTP, this proxy is the default route. For IPSec you can install
this proxy as a network route to the remote subnet.
NOTE If both Turbo Internet and PPP/ISDN are configured for demand
tunnels and demand dial, the idle timeouts are treated independently. If Turbo
Internet is configured for 90-second timeout, and the PPP is configured for a
120 second timeout, the modem will remain connected for 210 seconds after
the connection becomes idle. The tunnel will close after 90 seconds, and after
another 120 seconds of inactivity the modem will hang-up. If you change the
Demand Rules or timeout, you need to disconnect and reconnect PPP or
Turbo Internet.

Tunnel mode Enables AH or
ESP to process the network layer
protocol —the main advantage is
that the IP header can be fully
encrypted and authenticated. In
addition, it uses the IP address of
VPN initiator to hide the VPN
client's IP address.
Transport mode Enables AH or
ESP to process transport layer
field and /or higher layers of the
datagrams. Most of the time
compulsory Tunnels (EMR is the

configured in tunnel mode and
Voluntary Tunnels (client PC is

•
Remote Gateway IP Address: IP address of the remote gateway or VPN
concentrator.
•
IPSec mode: Select from “Tunnel Mode” or “Transport Mode”
NOTE Tunnel Mode applies ESP encryption and authentication to the entire
original IP packet (IP header and data), thus hiding the ultimate source and
destination addresses. This is the default selection, and it is the most secure.
Transport Mode applies ESP encryption and authentication only to the
transport layer segment (data only) of the original IP packet. This mode
protects packet contents but not the ultimate source and destination
addresses.

IPSec is very selective about which IP traffic is actually encrypted/authenticated
and sent through the tunnels. For traffic to be sent though an IPSec tunnel it
must have specific source and destination IP addresses. The tunnel mode
settings are used to configure these addresses.
•
For IP packets sent from EMR to the remote gateway, the IP packet source
address must match the Local Subnet and Local Subnet Mask settings. The IP
packet destination address must match the Remote Subnet and Remote
Subnet Mask settings.
•
For IP packets sent from the remote gateway to EMR, the IP packet source
address must match the Remote Subnet and Remote Subnet Mask settings.
The IP packet destination address must match the Local Subnet and Local
Subnet Mask settings. Otherwise, the packet will not travel through the IPSec
tunnel.
The end of an IPSec tunnel can terminate at an entire subnet or at the single IP
address of the IPSec gateway. This allows EMR to support four tunnel scenarios.
These scenarios describe which traffic is sent through the IPSec tunnels:
•
LAN-to-LAN: Traffic from local subnet (attached to EMR) to remote subnet
(attached to remote gateway). Both the local subnet and remote subnet must
be entered.
•
LAN-to-Gateway: Traffic from local subnet (attached to EMR) to the remote
gateway. Only the local subnet should be entered. The remote subnet should
be left blank.
171

before encrypting them.
Encryption Algorithm: Select from the following list: DES (56-bit), and
3DES (168-bit).
NOTE The EMR uses Triple-DES encryption as a default because it is the
most secure.
•
Authentication Algorithm: Select from “HMAC-MD5 (128-bit)” or
“HMAC-SHA1 (160-bit).”
NOTE MD5 uses a 128-bit hash and is fastest. SHA1 uses a 160-bit hash and
is more secure but requires more processing overhead.
•
Diffie-Hellman Group: Select from the following: Group 1 (768-bits),
Group 2 (1024-bits), and Group 3 (1536-bits).
NOTE The EMR uses Perfect Forward Secrecy (PFS) by default. PFS is a
cryptographic concept where each new key is unrelated to any previous key.
In IPSec negotiations, Phase 2 keys are based on Phase 1 keys unless
Perfect Forward Secrecy is specified. Perfect Forward Secrecy uses DiffieHellman techniques to generate the keys. You must select one of the
following groups and make sure that PFS is enabled at both the EMR and
VPN side:
Group 1 (768-bits) Use PFS and Diffie-Hellman Group 1 to generate IPSec
session keys, where the prime and generator numbers are 768 bits. This
option requires the least processing overhead.
Group 2 (1024-bits) Use PFS and Diffie-Hellman Group 2 to generate IPSec
session keys, where the prime and generator numbers are 1024 bits. This
option is more secure than Group 1 but requires more processing overhead.
Group 5 (1536-bits) Use PFS and Diffie-Hellman Group 5 to generate IPSec
session keys, where the prime and generator numbers are 1536 bits. This
option is more secure than Group 2 but requires more processing overhead.

The amount of time it takes to complete the download process is determined by
network traffic. The system will automatically bring up an information box
showing the current versions of the software currently installed on the system
including the new version.
5 Reboot the EMR to begin using the new software upgrade.
NOTE If an upgrade error or problem with the new download occurs, the EMR
is able to automatically fall back to the last successful working version.
Boot Selection
If boot selection is set to “Auto” mode, the boot loader will load the kernel that
is most up-to-date. If set to “Manual” mode, the user must select a kernel that is
currently available. This will be loaded the next time you boot the EMR. The
onboard flash has enough memory for two kernels: A Factory version on the
flash, which is the software load shipped with the unit, and two user versions.
The factory version cannot be deleted.
Choose a software kernel from the list box and click Apply to set the changes.
Feature Upgrade
The Feature Upgrade is used for applying additional pay features to the
SkyStream EMR. To activate the Feature Upgrades, SkyStream will give you an
upgrade key with your purchase. The upgrade key is entered into the Key field;
all you have to do is click the Apply button to enable the additional features.
NOTE When upgrading your EMR to enhance its capabilities, you will receive
an Upgrade Key string. The Basic software package provides support for up

NOTE If the setup is such that a large number of events are routinely
generated, SkyStream recommends that the Log File be changed to Warning
or Informational and that the Batching file be changed to a high enough value
so that the system is not slowed by constant updates to the Log File.
The default setting for the Log Info Level is chosen and designed to allow the
EMR to operate a maximum efficiency. By just logging the fatal errors, fewer
resources are being allocated to logging extra information to the flash memory.
The flash memory allocated for the log file information has a maximum size of
256K divided into two equal blocks of 128K each. When the memory on both
blocks is filled, the system erases the first block and begins writing again. This
will cause the system to remove the oldest log entries.

Error and Event
Logging
The EMR has error/event logging capabilities. The Log File can then be
accessed and printed out in order to troubleshoot system problems and/or send
the Log File to SkyStream Networks for further assistance. Contact SkyStream
Networks Customer Service with any questions or concerns.
Errors and events are reported and logged using the following mechanisms:
•
Through SNMP, as traps, the EMR will support up to four trap destination IP
addresses. The responsibility of the SNMP manager is to receive the traps and
save them in the Log File.
•
Using a standard Unix Syslog system, the EMR is configured to send log
entries to a standard syslog daemon.
•
Errors and events are logged and saved to the Log File.
NOTE Refer to the Log Information section in the Diagnostics chapter for

IPSec Debugging
IPSec negotiation occurs in two phases: Internet Key Exchange (IKE) is used to
create an Security Association (SA), followed by an IPSec Security Association
(SA). Both phases must succeed before any data can traverse the connection.
Due to the complexity of configuring IPSec, it may be necessary to debug
parameters. To access the IPSec debug log, from the Configuration-Turbo
Internet/VPN page, click the Advanced button, select logging preferences, and
click View Log; the bottom of the log will give debugging information.
IPSec Debug Log messages:
1 “initiating Main Mode”
If the connection is stuck here, it is likely that, either the packets cannot get to
the remote gateway, or the remote gateway IKE (Phase 1) parameters do not
match those on the EMR.
2 “informational payload, type NO_PROPOSAL_CHOSEN”
This message means that the IKE or IPSec parameters are not matched
between the EMR and the remote gateway. Check the settings for both IKE
and IPSec SAs and make sure they agree with the remote gateway.
3 “informational payload, type IPSEC_RESPONDER_LIFETIME”
EMR supports a re keying interval between 60 and 86400 seconds (one day).
This message means that the remote gateway is configured to use a re keying
interval that is outside the boundaries of what EMR supports. Change the re
208
Troubleshooting
EMR-5000 User’s Guide version 2.3
key interval on the remote gateway to be less that or equal to the interval set
on the EMR.
4 “we require PFS but Quick I1 SA specifies no GROUP_DESCRIPTION”
EMR uses Perfect Forward Secrecy by default. This message means that the
remote gateway is not correctly configured for PFS on the IPSec (not IKE)
Phase 2 negotiations. Enable PFS Diffie Hellman Group 1, 2, or 5 on the
remote gateway.
5 “informational payload, type INVALID_ID_INFORMATION”
This message means that the local subnet, local subnet mask, remote subnet,
or remote subnet mask do not agree with the remote gateway configuration.
Remember that EMR’s local subnet is the remote gateway’s remote subnet and
vice versa.
6 “informational payload, type INVALID_COOKIE”
This usually means the other side has rejected our connection attempt
immediately. Check that the remote gateway is accepting requests from
EMR's IP Address.
Password
Recovery
Procedure
In the event that you forget your password or user identity, the following
procedure will enable you to create a new one. Password recovery in itself is not
possible; however, you can bypass the system in an emergency. SkyStream will
give you a special key, so that when you boot the EMR, you will have sixty
seconds to type in the key; the system will erase the password. To gain access to
your EMR, you will be able to enter the default user identity and password.
If you do not have the special key, contact SkyStream Customer Support.
Password Recovery
The following steps take you through the process:
1 Connect to the EMR through a PC connected to the serial port.
2 Run HyperTerminal from Windows Accessories:
■
Click the Windows Start button
■
Choose Programs > Accessories > Hyperterminal
■
Click Hyper Terminal icon
3 From CLI or the Web GUI reboot the EMR.
4 In HyperTerminal, at the prompt type: resetpw
5 You have sixty seconds to type the special key (provided by SkyStream
Customer Support for each unit)
Upon entering this key, the old password will be erased and the EMR will
reboot. You can now gain access to the EMR through CLI or the Web GUI by
using the default user identity and password (see Chapter 3, “System Logon”).

ping
The following information can be found in the “UNIX System Manager's
Manual”
NAME
ping - send ICMP ECHO_REQUEST packets to network hosts
SYNOPSIS
ping [-dfnqrvR] [-c count] [-i wait] [-p pattern] [-s packetsize]
DESCRIPTION
Ping uses the ICMP protocol's mandatory ECHO_REQUEST datagram to elicit
an ICMP ECHO_RESPONSE from a host or gateway.
ECHO_REQUEST datagrams (”pings”) have an IP and ICMP header,
followed by a struct timeval and then an arbitrary number of pad bytes used to
fill out the packet.
The options are as follows:
-c count: Stop after sending (and receiving) count ECHO_RESPONSE packets.
-d: Set the SO_DEBUG option on the socket being used.
-i wait: Wait seconds between sending each packet. The default is to wait for
one second between each packet.
-n: Numeric output only. No attempt will be made to lookup symbolic names for
host addresses.
-p pattern: You may specify up to 16 pad bytes to fill out the packet you send.
This is useful for diagnosing data-dependent problems in a network. For
example, -p ff will cause the sent packet to be filled with all ones.
-q: Quiet output. Nothing is displayed except the summary lines at startup time
and when finished.
-R: Record rout e. Includes the RECORD_ROUTE opt ion in the
ECHO_REQUEST packet and displays the route buffer on returned packets.
Note that the IP header is only large enough for nine such routes. Many hosts
ignore or discard this option.
-r: Bypass the normal routing tables and send directly to a host on
an
attached network. If the host is not on a directly-attached network, an error is
returned. This option can be used to ping a
local host through an interface
that has no route through it (e.g., after the interface was dropped by routed(8)).
-s packetsize: Specifies the number of data bytes to be sent. The default is 56,
which translates into 64 ICMP data bytes when combined with the 8 bytes of
ICMP header data.
206
Command Definitions
EMR-5000 User’s Guide version 2.3
-v: Verbose output. ICMP packets other than ECHO_RESPONSE that are
received are listed. When using ping for fault isolation, it should first be run on
the local host, to verify that the local network interface is up and running. Then,
hosts and gateways further and further away should be pinged. Round-trip times
and packet loss statistics are computed. If duplicate packets are received, they
are not included in the packet loss calculation, although the round trip time of
these packets is used in calculating the minimum/average/maximum round-trip
time numbers. When the specified number of packets have been sent (and
received) or if the program is terminated with a SIGINT, a brief summary is
displayed.
If ping does not receive any reply packets at all it will exit with code 1. On error
it exits with code 2. Otherwise it exits with code 0. This makes it possible to use
the exit code to see if a host is alive or not.
This prog ram is intended for use in network testing, measurement, and
management. Because of the load it can impose on the network, it is unwise to
use ping during normal operations or from automated scripts.
ICMP PACKET DETAILS
An IP header without options is 20 bytes.
An ICMP ECHO_REQUEST packet contains an additional 8 bytes worth of
ICMP header followed by an arbitrary amount of data. When a packetsize is
given, this indicated the size of this extra piece of data (the default is 56). Thus
t h e a m o u n t o f d a t a r e c e i ve d i n s i d e o f a n I P p a c k e t o f t y p e I C M P
ECHO_REPLY will always be 8 bytes more than the requested data space (the
ICMP header). If the data space is at least eight bytes large, ping uses the first
eight bytes of this space to include a timestamp which it uses in the computation
of round trip times. If less than eight bytes of pad are specified, no round trip
times are given.
DUPLICATE AND DAMAGED PACKETS
Ping will report duplicate and damaged packets. Duplicate packets should never
occur and seem to be caused by inappropriate link-level retransmissions.
Duplicates may occur in many situations and are rarely (if ever) a good sign,
although the presence of low levels of duplicates may not always be cause for
alarm.
Damaged packets are obviously serious cause for alarm and often indicate
broken hardware somewhere in the ping packet's path (in the network or in the
hosts).
TRYING DIFFERENT DATA PATTERNS
The (inter)network layer should never treat packets differently depending on the
data contained in the data portion. Unfortunately, data-dependent problems
have been known to sneak into networks and remain undetected for long periods
of time. In many cases the particular pattern that will have problems is
something that doesn't have sufficient transitions, such as all ones or all zeros, or
207
SkyStream Networks
a pattern right at the edge, such as almost all zeros. It isn't necessarily enough to
specify a data pattern of all zeros (for example) on the command line because
the pattern that is of interest is at the data link level, and the relationship
between what you type and what the controllers transmit can be complicated.
This means that if you have a data-dependent problem you will probably have to
do a lot of testing to find it. If you are lucky, you may manage to find a file that
either can't be sent across your network or that takes much longer to transfer
than other similar length files. You can then examine this file for repeated
patterns that you can test using the -p option of ping.
TTL DETAILS
The TTL value of an IP packet represents the maximum number of IP routers
that the packet can go through before being thrown away. In current practice
you can expect each router in the Internet to decrement the TTL field by exactly
one.
The TCP/IP specification states that the TTL field for TCP packets should be
set to 60, but many systems use smaller values (4.3 BSD uses 30, 4.2 used 15).
The maximum possible value of this field is 255, and most Unix systems set the
TTL field of ICMP ECHO_REQUEST packets to 255. This is why you will find
you can ping some hosts, but not reach them with telnet(1) or ftp(1).
In normal operation ping prints the TTL value from the packet it receives. When
a remote system receives a ping packet, it can do one of three things with the
TTL field in its response:
Not change it; this is what Berkeley Unix systems did before the 4.3BSD-Tahoe
release. In this case the TTL value in the received packet will be 255 minus the
number of routers in the round-trip path.
Set it to 255; this is what current Berkeley Unix systems to. In this case the TTL
value in the received packet will be 255 minus the number of routers in the path
from the remote system to the pinging host.
Set it to some other value. Some machines use the same value for ICMP packets
that they use for TCP packets, for example either 30 or 60. Others may use
completely wild values.
BUGS
Many Hosts and Gateways ignore the RECORD_ROUTE option. The maximum
IP header length is too small for options like RECORD_ROUTE to be
completely useful. There's not much that can be done about this, however.
Flood pinging is not recommended in general, and flood pinging the broad cast
address should only be done under very controlled conditions.
HISTORY
The ping command appeared in 4.3BSD.

route - show / manipulate the IP routing table
SYNOPSIS
route [-CFvnee]
route [-v][-A family]add [-net|-host]target [netmask Nm][gw Gw] [metric

route [-V][--version][-h][--help]
DESCRIPTION
Route manipulates the kernel's IP routing table. Its primary use is to set up
static routes to specific hosts or networks via an interface after it has been
configured with the ifconfig(8) program.
OPTIONS
-v: Select verbose operation.
-A family: Use the specified address family (e.g. inet, inet6).
-n: Show numerical addresses instead of trying to determine symbolic host
names. This is useful if you are trying to determine why the route to your
nameserver has vanished.
-e: Use netstat(8)-format for displaying the routing table. -ee will generate a very
long line with all parameters from the routing table.
-net: The target is a network
-host: The target is a host
-F: Displays the kernel FIB routing table. The layout can be changed with -e and
-ee
-C: Displays the kernel's route cache
del: Deletes a route
add: Adds a route
target: The destination network or host. You can provide IP addresses in dotted
decimal or host/network names.
netmask Nm: Modifier specifies the netmask of the route to be added.
209
SkyStream Networks
gw Gw: Any IP packets for the target network/host will be routed through the
specified gateway.
NOTE: The specified gateway must be reachable first. This usually means
that you have to set up a static route to the gateway beforehand. If you specify the address of one of your local interfaces, it will be used to decide about
the interface to which the packets should be routed to. This is a BSDism compatibility hack.
metric M: Set the metric field in the routing table (used by routing daemons) to
M.
mss M: Set the TCP Maximum Segment Size (MSS) for connections over this
route to M bytes. This is normally used only for fine optimization of routing
setups. The default is 536.
window W: Set the TCP window size for connections over this route to W
bytes. This is typically only used on AX.25 networks and with drivers unable to
handle back to back frames.
irtt I: Set the initial round trip time (irtt) for TCP connections over this route to
I milliseconds (1-12000). This is typically only used on AX.25 networks. If
omitted the RFC 1122 default of 300ms is used.
reject: Install a blocking route, which will force a route lookup to fail. This is
for example used to mask out networks before using the default route. This is
NOT for fire-walling.
mod, dyn, reinstate: Install a dynamic or modified route. Both flags are
generally only set by a routing daemon.This is only for diagnostic purpose.
dev If: Forces the route to be associated with the specified device, as the kernel
will otherwise try to determine the device on its own (by checking already
existing routes and device specifications, and where the route is added to). In
most normal networks you won't need this.
If dev: If is the last option on the command line, the word dev may be omitted,
as it's the default. Otherwise the order of the route modifiers (metric - netmask gw - dev) doesn't matter.
EXAMPLES
route add -net 127.0.0.0: Adds the normal loopback entry, using netmask
255.0.0.0 (class A net, determined from the destination address) and associated
with the “lo” device (assuming this device was previously setup correctly with
ifconfig(8)).
route add -net 192.56.76.0 netmask 255.255.255.0 dev eth0: Adds a route to
the network 192.56.76.x via “eth0”. The Class C netmask modifier is not really
necessary here because 192.* is a Class C IP address. The word “dev” can be
omitted here.
route add default gw mango-gw: Adds a default route (which will be used if
no other route matches). All packets using this route will be gatewayed through
“mango-gw”. The device which will actually be used for that route depends on
210
Command Definitions
EMR-5000 User’s Guide version 2.3
how we can reach “mango-gw” - the static route to “mango-gw” will have to be
set up before.
route add ipx4 sl0: Adds the route to the “ipx4” host via the SLIP interface
(assuming that “ipx4” is the SLIP host).
route add -net 192.57.66.0 netmask 255.255.255.0 gw ipx4: This command
adds the net “192.57.66.x” to be gatewayed through the former route to the
SLIP interface.
route add 224.0.0.0 netmask 240.0.0.0 dev eth0: This is an obscure one
documented so people know how to do it. This sets all of the class D (multicast)
IP routes to go via “eth0.” This is the correct normal configuration line with a
multicasting kernel.
route add 10.0.0.0 netmask 255.0.0.0 reject: This installs a rejecting route for
the private network “10.x.x.x.”
OUTPUT
The output of the kernel routing table is organized in the following columns:
Destination: The destination network or destination host.
Gateway: The gateway address or ‘*’ if none set.
Genmask: The netmask for the destination net; ‘255.255.255.255’ for a host
destination and ‘0.0.0.0’ for the default route.
Possible flags are:
U (route is up)
H (target is a host)
G (use gateway)
R (reinstate route for dynamic routing)
D (dynamically installed by daemon or redirect)
M (modified from routing daemon or redirect)
! (reject route)
Metric: The ‘distance’ to the target (usually counted in hops). It is not used by
recent kernels, but may be needed by routing daemons.
Ref Number of references to this route. (Not used in the Linux Kernel.)
Use: Count of lookups for the route. Depending on the use of -F and -C this
will be either route cache misses (-F) or hits (-C).
Iface: Interface to which packets for this route will be sent.
MSS: Default maximum segment size for TCP connections over this route.
Window Default: window size for TCP connections over this route.
irtt: Initial RTT (Round Trip Time). The kernel uses this to guess about the best
TCP protocol parameters without waiting on (possible slow) answers.
211
SkyStream Networks
HH (cached only): The number of ARP entries and cached routes that refer to
the hardware header cache for the cached route. This will be -1 if a hardware
address is not needed for the interface of the cached route (e.g. lo).
Arp (cached only): Whether or not the hardware address for the cached route
is up to date.

netstat
NAME
netstat - Display network connections, routing tables, interface statistics,
masquerade connections, netlink mes- sages, and multicast memberships
SYNOPSIS
netstat [-venaocs] [--tcp|-t] [--udp|-u] [--raw|-w] [--groups|-g] [--unix|-x] [-inet|--ip] [--ax25] [--ipx] [--netrom] netstat [-venc] [--inet] [--ipx] [--netrom] [-ddp] [--ax25] {--route|-r} netstat [-venpac] {--interfaces|-i} [iface] netstat [enc] {--masquerade|-M} netstat [-cn] {--netlink|-L} netstat {-V|--version} {h|--help} :
DESCRIPTION
Netstat displays information of the Linux networking sub- system. (no option)
You can view the status of network connections by listing the open sockets. This
is the default operation: If you don't specify any address families, then the active
sockets of all configured address families will be printed. The address family inet
will display raw, udp and tcp sockets.
-a, --all The -a, --all option will print information about all sockets, including
the listening server sockets.
-l, --listening The -l, --listening option will print information about listening
server sockets only.
-e, --extend The -e, --extend option prints some additional information : (e.g.
user id and inode of the connection).
-p, --programs The -p, --programs option displays additional information about
the program that is using the socket (e.g. process id and the name of the
program).
-v, --verbose The -v, --verbose switch makes netstat complain about known
address families which are not supported by the kernel.
-r, --route With the -r, --route option, you get the kernel routing tables in the
same format as route -e use. netstat -er will use the output format of route.
Please see route(8) for details.
-g, --groups With the -g, --groups option, IGMP multicast group member- ship
information for IPv4 and IPv6 is displayed.
-i, --interface iface If you use the -i, --interfaces option, a table of all (or the
specified iface) networking interfaces will be printed. The output uses the
ifconfig -e format, and is described in ifconfig(8). netstat -ei will print a table or
a single interface entry just like ifconfig does. With the -a switch, you can include
interfaces which are not configured (i.e. don't have the U=UP flag set).
213
SkyStream Networks
-M, --masquerade A list of all masqueraded sessions can be viewed, too. With
the -e switch you can include some more infor mations about sequenze
numbering and deltas, caused by data rewrites on FTP sessions (PORT
command). Masquerade sup- port is used to hide hosts with unofficial network
addresses from the outside world, as described in ipfw(4),ipfwadm(8) and
ipfw(8).
-L, --netlink Recent kernels have a kernel/user communication support called
netlink. You can get messages about creation or deletion of interfaces or routes
from /dev/route (36,0).
OPTIONS
-v, --verbose Tell the user what is going on by being verbose. Especially print
some useful informations about unconfigured address families.
-n, --numeric Shows numerical addresses instead of trying to determine
symbolic host, port or user names.
-p, --programs Displays process name and PID of the owner of each socket it
dumps. You have to be the owner of such process to have all it's sockets matched
to it or generally root user will see all the necessary information in place.
-A, --af family Use a different method to set the address families. family is a
comma (',') separated list of address family key- words like inet, unix, ipx, ax25,
netrom and ddp. This is has the same effect as using the long options --inet, -unix, --ipx, --ax25, --netrom and --ddp. -c, --continous : This will cause netstat to
print the selected table every second continuously on the screen until you
interrupt it.
OUTPUT
Active Internet connections (TCP, UDP, RAW)
Proto The protocol (tcp, udp, raw) used by the socket.
Recv-Q The count of bytes not copied by the user program connected to this
socket.
Send-Q The count of bytes not acknowledged by the remote host.
Local Address The local address (local hostname) and port number of the
socket. Unless the -n switch is given, the socket address is resolved to its
canonical hostname, and the port number is translated into the corresponding
service name.
Foreign Address The remote address (remote hostname) and port number of
the socket. As with the local address:port, the -n switch turns off hostname and
service name resolution.
State The state of the socket. Since there are no states in RAW and usually no
states used in UDP, this row may be left blank. Normally this can be one of
several values:
ESTABLISHED The socket has an established connection.
214
Command Definitions
EMR-5000 User’s Guide version 2.3
SYN_SENT The socket is actively attempting to establish a connection.
SYN_RECV A connection request has been received from the network.
FIN_WAIT1 The socket is closed, and the connection is shutting down.
FIN_WAIT2 Connection is closed, and the socket is waiting for a shutdown
from the remote end.
TIME_WAIT The socket is waiting after close to handle packets still in the
network.
CLOSED The socket is not being used.
CLOSE_WAIT The remote end has shut down, waiting for the socket to close.
LAST_ACK The remote end shut down, and the socket is closed. Waiting for
acknowledgement.
LISTEN The socket is listening for incoming connections. Those sockets are
only displayed if the -a,--listening switch is set.
CLOSING Both sockets are shut down but we still don't have all our data sent.
UNKNOWN The state of the socket is unknown.
User The name or the UID of the owner of the socket.
PID/Program name Slash-separated pair of the PID and process name of the
program holding this socket. Option -p enables display of this column. You will
also need root privileges as you have to have access rights to process to be able
to see the program's sockets matched up to it. This identification information is
not yet available for IPX sockets.
Timer (this needs to be written)
Active UNIX domain Sockets Proto The protocol (usually unix) used by the
socket.
RefCnt The reference count (i.e. attached processes via this socket).
F l a g s T h e f l a g s d i s p l ay e d i s S O _ AC C E P T O N ( d i s p l ay e d a s AC C ) ,
SO_WAITDATA (W) or SO_NOSPACE (N). SO_ACCECPTON is used on
unconnected sockets if their corresponding processes are waiting for a connect
request. The other flags are not of normal interest.
Type There are several types of socket access:
SOCK_DGRAM The socket is used in Datagram (connectionless) mode.
SOCK_STREAM This is a stream (connection) socket.
SOCK_RAW The socket is used as a raw socket.
SOCK_RDM This one serves reliably-delivered messages.

to the socket.
Active IPX sockets (this needs to be done by somebody who knows it)
Active NET/ROM sockets (this needs to be done by somebody who knows it)
Active AX.25 sockets (this needs to be done by somebody who knows it)
NOTE Since kernel release 2.2 netstat -i does not display interface statistics
for alias interfaces anymore. To get per alias interface counters you need to
setup explicit rules using the ipchains(8) command.

SkyStream Networks
Working with Applications
This appendix contains the following sections:
•
•
Overview
Overview outlines the main issues involved in working with applications.
Connecting TCP Acceleration Client to a LAN describes how users can
connect to a LAN and optimize Internet applications to work with TCP
Acceleration. This refers specifically to Netscape and Internet Explorer.
•
Working with Mail Programs describes how to configure mail clients to
work with TCP Acceleration.
•
Configuring Standalone FTP Applications describes how to perform file
transfers using the TCP Acceleration Client.
•
Configuring News Protocols describes how to configure news clients to
work with TCP Acceleration.
You can use TCP Acceleration with various browsers, mail programs and FTP
applications. This means that your HTTP requests, e-mails and file transfers
from these configured applications are sent through the TCP Acceleration
Server.
This appendix describes how to connect TCP Acceleration to the local area
network (LAN), enabling it to act as your proxy server. This allows you to
configure Netscape and Internet Explorer browsers to work with TCP
Acceleration. In addition, this appendix describes how to configure mail clients
and standalone FTP applications to work with TCP Acceleration components.
Connecting the
TCP Acceleration
Client to a LAN
During installation, TCP Acceleration automatically configures the proxy
settings of your Netscape and Internet Explorer browsers. You can further
improve the speed of your Internet connection by using the TCP Acceleration
Client as a proxy server.
For HTTP and FTP requests, you must define the IP address of the TCP
Acceleration Client as your proxy server. TCP Acceleration Clients that are used
by multiple users connecting through a LAN are called TCP Acceleration Group
Clients.
This section describes the proxy configuration for Netscape and Internet
Explorer browsers in the following two sub-sections:

requests initiated by various e-mail applications. To use TCP Acceleration with
mail, you must configure the mail client to work with TCP Acceleration and
configure TCP Acceleration to work with the mail server. In order to configure
the mail client to work with TCP Acceleration, you must define the IP address of
the TCP Acceleration Client for outgoing mail (SMTP) ser ver and for the
incoming mail (POP3) server. The mail parameters are included in Chapter 5,
“Configuring TCP Acceleration—Network Settings.”
To configure your mail client to work with TCP Acceleration:
1 In the Network Settings pane—Server Side Settings, POP3 Server Address box,
enter the IP address of your POP3 mail server.

receiving wire.
•
•
On Air Broadcasting.
Original Destination IP Address Client address where the multicast stream
is being sent.
•
OS (Operating System) The master control program that runs the computer.
The operating system is the first program loaded after the computer is turned
on, and its main part, called the “kernel,” resides in memory at all times.
•
Packet Any block of data sent over a network. Each packet can contain
sender, receiver, and error-control information, in addition to the actual
message. Packets can be of fixed-length or variable-length and reassembled, if
necessary, when they reach their destination.
•
PAP (Password Authentication Protocol) The most basic access control
protocol for logging onto a network. A table of usernames and passwords is
stored on a server. When users log on, their usernames and passwords are sent
to the server for verification.

•
Payload The data-carrying capacity of some structure. It typically refers to a
part of a packet or frame in a communications system that holds the message
data in contrast to the headers, which are considered overhead.
•
PC (Personal Computer) A stand-alone computer that can be used as a
workstation and file server in a LAN (local area network).
•
PID (Packet Identifier) A 13 bit packet identifier used to identify different
data types inside the transport stream.
•
Ping An Internet utility used to determine whether a particular IP address is
online. Ping is used to test and debug a network by sending out a packet and
waiting for a response.
•
Polarization A technique used by the satellite designer to increase the
capacity of the satellite transmission channels by reusing the satellite
transponder frequencies. In linear cross polarization schemes, half of the
transponders beam their signals to earth in a vertically polarized mode; the
other half horizontally polarize their down links. Although the two sets of
frequencies overlap, they are 90 degree out of phase, and will not interfere
with each other. To successfully receive and decode these signals on earth, the
earth station must be outfitted with a properly polarized feedhorn to select
the vertically or horizontally polarized signals as desired.
•
PPP (Point-to-Point Protocol) A data link protocol that provides packetoriented communication over serial lines. PPP also provides password
protection using the Password Authentication Protocol (PAP).
•
PPTP (Point-to-Point Tunneling Protocol) A protocol that encapsulates
other protocols for transmission over an IP network. For example, it can be
used to send NetWare IPX packets over the Internet. Due to its RSA
encryption, PPTP is also used to create a private network (VPN) within the
public Internet. Remote users can access their corporate networks via any ISP
that supports PPTP on its servers.
•
Protocol Translation The process of receiving data payloads in one protocol
and retransmitting these payloads in another protocol.
•
PSK (Pre-Shared Key) A prearranged passphrase that is shared by two sides.
PSK is an authentication method for IPSec.
•
QPSK (Quadrature Phase Shift Keying) A method of modulating digital
signals using four phase states to code two digital bits per phase shift.
•
Reed Solomon Algorithm A system that corrects data errors with a
mathematical algorithm.
•
RF (Radio Frequency) The range of electromagnetic frequencies above the
audio range and below visible light. All broadcast transmission, from AM
radio to satellites, falls into this range, which is between 30 KHz and 300
GHz.

•
RIP (Routing Information Protocol) A simple routing protocol that is part of
the TCP/IP protocol suite. It determines a route based on the smallest hop
count between source and destination.
•
Router A device that forwards data packets from one local area network
(LAN) or wide area network (WAN) to another. Based on routing tables and
routing protocols, routers read the network address in each transmitted
frame and make a decision on how to send it based on the most expedient
route.
•
•
•
Server A computer in a network shared by multiple users.
•
SMTP (Simple Mail Transfer Protocol) The standard e-mail protocol on the
Internet. It is a TCP/IP protocol that defines the message format and the
message transfer agent (MTA), which stores and forwards the mail. SMTP was
originally designed for only ASCII text, but MIME and other encoding
methods enable program and multimedia files to be attached to e-mail
messages.
•
SkyNAT EMR application used to support packet translation of incoming
data from satellite for address translation, protocol translation, and TTL
translation.
•
SNMP (Simple Network Management Protocol) A standard protocol to
manage devices on the network.
•
Static IP address A permanent IP address that is assigned to a node in a
TCP/IP network. Servers and routers are usually assigned static IP addresses,
while client stations are often assigned dynamic IP addresses from a DHCP
server each time they come online.
•
Subnet Mask The Subnet Mask is used to divide the IP address space into
ranges of addresses called “subnets”. IP hosts in a subnet assume that they
have a direct connection (e.g., connected to the same Ethernet hub) and talk
directly to each other. The subnet mask divides the IP address into parts: a
network number and a host number. Hosts whose network number is the
same are in the same subnet. The subnet mask is a 32-bit field where “1” bits
indicate what part of the IP address is a network number. Subnet masks are
typically expressed in the same quad dotted notation as IP addresses.
•
TCP/IP The Transmission Control Protocol (TCP) on top of the Internet
Protocol (IP). Enables communication between different types of computers
and computer networks. The Internet Protocol is a connectionless protocol
that provides packet routing. TCP, which is connection-oriented, provides
reliable communication.
SkyCast The SkyStream system used for IP Multicast Management.
SMMP (SkyStream’s Multicast Management Protocol) This protocol uses
standard IP multicast to control groups of EMR units. A proprietary protocol
is required because the standard control protocols have the following
limitations.
Glossary
EMR-5000 User’s Guide version 2.3
•
TTL (Time To Live) This value decrements each time the IP packet moves
through a router. When the number reaches the value of zero, the packet is
discarded.
•
Transport mode Enables AH or ESP to process transport layer field and /or
higher layers of the datagrams. Most of the time, compulsory Tunnels (EMR
is the terminating edge) can be configured in tunnel mode and Voluntary
Tunnels (client PC is terminating edge) in transport mode.
•
Tunnel mode Enables AH or ESP to process the network layer protocol —
the main advantage is that the IP header can be fully encrypted and
authenticated. In addition, it uses the IP address of VPN initiator to hide the
VPN client's IP address.
•
UDP (User Datagram Protocol) A connectionless transport-level protocol
used in the suite of IP-based protocols. It enables the sending of data from
one computer to an application running on another computer. Like TCP
(Transmission Control Protocol), UDP is used with IP (the Internet
Protocol). Unlike TCP, UDP is connectionless and does not guarantee reliable
communication; the application must deal with lost or out-of-order packets.
•
Unicast To transmit from one station to another, such as from client to
server or server to server.
•
UTC (Universal Time, Coordinated) Coordinated Universal Time differs
from International Atomic Time by an integral number of seconds and is the
basis of most radio time systems and legal time systems. The step adjustments
(Leap Seconds) are usually inserted after the 60th second of the last minute of
December 31 or June 30.
•
VPN (Virtual Private Networking) Emulates point-to-point connectivity. For
a secure VPN, data is encrypted using a protocol called the Point-to-Point
Tunneling Protocol (PPTP), or IPSec.
•
VSAT (Very Small Aperture satellite Terminal) A small earth station for
satellite transmission that handles up to 56 kbits/sec of digital transmission.
•
WAN (Wide Area Network) A communications network that covers a wide
geographic area, such as state or country.
