Network Architecture


Network Architecture (cont’d)


Network Architecture ( cont’d )



3 types of WebSAMS users



WebSAMS user





ITED user

Internet user



HTTP server is simply a relay server which forwards all the requests to the WebSAMS server



The HTTP server itself does not store any data





Accessing WebSAMS by URL



Determined by Domain Name Server (DNS)



Accessing the WebSAMS server from different subnets or networks will use different IP addresses



Examples:



WebSAMS users:





 websams.schabc.edu.hk => 10.128.30.150

ITED users:

 websams.schabc.edu.hk => 10.128.15.150 / 192.168.0.3

Internet users:

 websams.schabc.edu.hk => 202.123.219.100





Router ( between WebSAMS and ITED )



HTTP Server connect to WebSAMS server







Using TCP 8009 for production

Using TCP 7009 for training

Using TCP 8109 for 1 server 2 SAMS



WebSAMS server can access Internet without passing through proxy







TCP 80 ( HTTP )

TCP 443 ( HTTPS )

TCP/UDP 53 ( DNS )





TCP 25 ( SMTP )

TCP 110 ( POP3 )





Internet Gateway



Support NAT ( Network Address Translation )



Port mapping







TCP 80

TCP 443

TCP 7010


Internet Gateway





Separate Internet and ITED



2 interfaces - one for real IP and another for internal IP

It could be:



Hardware firewall ( e.g. SonicWALL , Cisco PIX, Netscreen,

CheckPoint, and so on … )









Proxy server with NAT function

Router with NAT function

Linux server ( 2 interface cards , using iptables or ipchains + ipmasqadm )

Windows server ( 2 interface cards , routing and remote access )


DMZ













It is called “Demilitarized Zone”

A separated area between Internet and Local Area

Network

Internet gateway should has at least 3 interfaces to support DMZ, such as Internet, ITED LAN segment &

DMZ

Provide services opened to public

Aggregate servers, such as FTP server, Web server, and so on, in a restricted area

Help to minimize impact to LAN in case of school network being hacked



Use command “ fdisk -l ” to check USB device name e.g.: sda1, sda2 or sdb1…,etc.



Use command “ grepconfig ” / “ grepconfig /dev/{USB device name}

(For 1 Server 2 WebSAMS environment, use “ grepconfig_1s2s ”)

”.





Run the command when HTTP server is running in good condition

Those files can be copied to any Windows storage for backup purpose


Backup in HTTP Server ( cont’d )



Step 1 : Log in HTTP server as root



Step 2 : Type command “ grepconfig /dev/sda1 ”.



Step 3 : Press “Y” in the following screen









Step 4: Press “0” if all information is correct

Step 5: Press “Y” to confirm in the following screen


Internet Security



Only open WebSAMS to Internet access for a specific period when necessary:

1. Restrict the time for accessing WebSAMS from clients outside SAMS LAN segment at “Security > Configuration >

System Configuration”


Internet Security ( cont’d )

2. Set up specific “Internet Access Time Profile” to further control the access time for particular user clients outside

SAMS LAN segment at “Security > Access Control > Internet

Access Time Profile ”





3. For more security, you may deny the access to port TCP

443 in the Internet gateway



In the firewall, deny the network accessing to port TCP 443, except the IP addresses of the Primary & Secondary CDS

Servers to allow packets passing through this port.



This action requires efforts from vendors or support staff in school who possess special knowledge and experience on security and firewall.

IT System Security









All WebSAMS users are required to have their own identities (i.e. user accounts)

Passwords should not be shared or divulged unless necessary

For safeguarding WebSAMS security, please remind to follow the guidelines of “IT Security in Schools” (ITSS): http://www.edb.gov.hk/FileManager/EN/Content_1619/it%20security%20in

%20schools.pdf

Regularly visit the Information Security website of HKSAR

Trouble-shoot Case Studies

General trouble-shoot ( Helpdesk issues )



10 general issues frequently received by

WebSAMS Helpdesk:

1.

ITED / Internet cannot access WebSAMS

2.

Unable to connect CDS

3.

Unable to back up

4.

How to setup WebSAMS client PC?

5.

ITED-access becomes Internet-access

6.

WebSAMS-access becomes ITED-access

7.

Unable to find Apache Window

8.

Generate report problem

9.

Fonts problem

10. Version upgrade problem


1. ITED / Internet cannot access WebSAMS

















Double check whether WebSAMS has been started ?

Test if WebSAMS segment works or not

Check whether ITED client PC has resolved the IP





DNS problem / DHCP problem

Proxy client problem ?

Check using “Internet Explorer” on the ITED client PC

Check whether the ITED client PC uses proxy in IE ?

Confirm whether HTTP server has been started up & the ‘Pass Phrase’ has been entered?

Idle 25 seconds > rcapache2 restart

In HTTP server, do the test by typing:

 telnet <WebSAMS_server_IP> 8009



( cont’d )



Success Sample



Failure Sample



( cont’d )





If succeed, it must be ITED segment problem

If fail, it could be:



HTTP server crash







HTTP server wrong setting

WebSAMS’s router wrong setting ( or reset )

School firewall setting if HTTP server in DMZ



If it can load SSL prompt, that means HTTP running smoothly.

Otherwise, it may be HTTP setting or router setting problem



( cont’d )



ITED can access WebSAMS successfully but Internet cannot. The problem is due to:



Hosting registration of WebSAMS domain name in Internet





Internet Gateway problem ( port mapping )

HTTP server’s Default Gateway setting is wrong



It should be set to the Internet Gateway which performs port mapping



Type “route” in Linux command line to show default gateway setting


2. Unable to connect CDS



It may be caused by:









Network connection of WebSAMS server has ever broken a short period

Wrong URL of the Primary and Secondary CDS Extensions in

WebSAMS at “CDS > Transmission > Schedule Transmission”

Wrong Internet Gateway setting

Wrong WebSAMS router setting



In WebSAMS server, try to connect Internet without passing through proxy



Go to (www.hsbc.com.hk) then click “logon” to test whether https URL works or not;



Try to ping: cdsx1.websams.edb.gov.hk and cdsx2.websams.edb.gov.hk



If fail, it may be DNS problem


2. Unable to connect CDS ( cont’d )



Nearly 95% of network problem with the message of

“Unable to connect CDS” could not pass the following testing.



 e.g. Internet Gateway did not allow WebSAMS server access

Internet e.g. WebSAMS router setting had a wrong ACL or wrong default route



A very special case may happen that CDS can send but cannot receive messages.



Under our investigation , it may be caused by the ISP and network setting



Solution :



Implement “packet-too-big” into router setting


3. Unable to back up





Hardware failure or no free space of hard disk in NAS

Besides, over 95% of cases are due to the following 3 reasons :







Backup task is configured wrongly

Backup task spends too much time that causes post_backup starting early than estimation

The administrator password in system does not synchronize with one from backup batch jobs



For case 3 above, we need to :







Change the password in pre_backup , post_backup

Change the password in Backup software

All password settings must be same as system administrator password


4. How to setup WebSAMS client PC?









OS requires Windows Vista or above
