Configuring FTP
• When the AS/400 acts as a server, it
allows clients to access physical, logical,
source and save files and members stored
on the system
• When files are transferred to a client
system , the AS/400 automatically
translates them from EBCDIC to ASCII,
but files can also be transferred without
translation.
Configuring
CHGFTPA
FTP
autostart
*yes (STRTCP)
*no
(STRTCPSVR)
. FTP server doesn’t need to be active for the AS/400 to initiate a
file transfer, either to or from the AS/400.
. The only need for the FTP server to be active on the AS/400 is
for a remote system to initiate a file transfer to or from the
AS/400.
. NBRSVR: The default FTP servers to be started automatically
is three. (1----20)
. INACTTIMO: The default number of seconds that an FTP
connection can remain idle before the AS/400 disconnects the
FTP connection is 300 seconds. (0----68years)
0 = NO Timeout

The default Telnet server to be started automatically is one.
You can start additional Telnet servers by using the command :
STRTCPSVR SERVER(*Telnet)
INACTTIMO: The default number of seconds that an Telnet
connection can remain idle before the AS/400 disconnects
the Telnet connection is 0 seconds, meaning idle connections
will not be broken.
(Valid range: 0----68years) 0 = No Timeout

Configuring SMTP
• SMTP is used to transfer mail
between host.
• POP3 is used to transfer mail from a
host to a client.
• AS/400 supports both SMTP and
POP3.
STRTCP - 1
Start TCP/IP (STRTCP)
Where allowed to run: All environments (*ALL)
•
The Start TCP/IP (STRTCP)
–
–
–
–
command initializes and activates TCP/IP processing
starts the TCP/IP interfaces
starts the TCP/IP server jobs
starts the TCP/IP Point-To-Point (PTP) profiles.
A STRTCP command must be issued before any TCP/IP processing can be
performed on the iSeries. This includes Simple Network Management
Protocol (SNMP) agent processing.
•
The TCP/IP interfaces that are started are those that have set the
AUTOSTART parameter to a value of *YES using the Add TCP/IP
Interface (ADDTCPIFC), the Change TCP/IP Interface (CHGTCPIFC)
commands, or the iSeries Navigator.
•
The Change IPL Attributes (CHGIPLA) command with the STRTCP
parameter set to a value of *YES can be used to automatically submit
the STRTCP command at the completion of IPL.
TCP/IP Management
GO TCPADM
TCP/IP Management
• Using the TCP/IP management tools to keep TCP/IP
on your AS/400 robust, reliable and effective.
• Each option of the menu GO TCPADM has an
associated command.

The components of TCP/IP
processing on the AS/400 include:
•
•
•
•
The TCP/IP jobs
The physical connection over the line
The logical connection to the network
Optional SNMP services
PING
• Can help find problems in logical connections
• If the connection is successful ,receives a return reply.
• If the packet never returns, there is no route from the
source to the destination system and back again. This
does not mean that TCP/IP is not configured correctly;
it may mean that the routing is not established properly.
• If the packet does make a successful round trip, the
time that it takes to make the round trip may be
excessive. You may need to examine your network for
potential performance or bottleneck problem
TCP/IP connection status
• Listen--- the AS/400 is listening at the local port for an
incoming connection
• Established--- the connection is established and the
system are communicating
• Closed --- the connection has ended
• Other states may be seen during a transition period
• The ports( both remote and local) can use well-known
names rather than a port number. These names are
defined in the service table modified by the command
WRKSRVTBLE
TCP/IP connection details
• The number of bytes in and out ( from AS/400
perspective) for this connection.
• The retransmission information gives the number of
segments retransmitted by the AS/400 due to an
acknowledgement not being received.
• If the number of retransmission is higher than the
number that has been historically present for this
connection, it could be an indication that there are
network problems.
TCP/IP connection details
• The send window information identifies the current and
largest size of the send window, or the number of bytes
that can be transmitted without an acknowledgment.
• A large send window indicates that the network is
successfully transmitting large packets without the
need for retransmission.
• A small send window size means that the system has
detected problems and has reduced the window size in
an attempt to reduce the number of retransmissions.
