Seminar on Server, Network and Security for WebSAMS
WebSAMS Architecture
WebSAMS Requirements


WebSAMS server can access Internet without passing
through proxy
WebSAMS server can access HTTPS web site, e.g.:



HTTP server can access Internet without passing through
proxy
Support NAT port mapping, e.g.:



E.g. www.hsbc.com.hk  logon
202.123.219.100  10.128.15.150
TCP 80,443,7010
Allow traffic from DMZ HTTP to WebSAMS server


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

B-6
Network Architecture ( cont’d )

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:


ITED users:


websams.schabc.edu.hk => 10.128.15.150 / 192.168.0.3
Internet users:

Sep 2015
websams.schabc.edu.hk => 10.128.30.150
websams.schabc.edu.hk => 202.123.219.100
Seminar on Server, Network and Security for WebSAMS

Network Architecture ( cont’d )

Router ( between WebSAMS and ITED )

HTTP Server connect to WebSAMS server




WebSAMS server can access Internet without passing through
proxy

Using TCP 7009 for training
Using TCP 8109 for 1 server 2 SAMS
TCP 80 ( HTTP )
TCP 443 ( HTTPS )
TCP/UDP 53 ( DNS )
TCP 25 ( SMTP )
TCP 110 ( POP3 )

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

Translate the IP address from one network to other
network

Typically one is inside and one is outside

Port mapping function

3. For more security, you may deny the access to port TCP
443 in the Internet gateway


Sep 2015
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
( http://www.infosec.gov.hk ) for updated information of IT
security

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 problem ?



DNS problem / DHCP problem
Proxy client
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:

1. ITED / Internet cannot access WebSAMS
( 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
Sep 2015
Seminar on Server, Network and Security for WebSAMS
B - 88
1. ITED / Internet cannot access WebSAMS
( 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


Sep 2015
It should be set to the Internet Gateway which performs port
mapping
Type “route” in Linux command line to show default gateway
setting
Seminar on Server, Network and Security for WebSAMS
B - 89
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

Sep 2015

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 :

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

Other FAQ sharing
1. Unable to access WebSAMS after WebSAMS server rebooted.
Ans: Suggest accessing the WebSAMS Training System.
If it works normally, user may wrongly start WebSAMS in
“WebSAMS_T” folder. For production service, it should start WebSAMS
in “WebSAMS” folder.
If it is still unable to access, suggest user to ensure there is no
interruption on the command mode process on the server (Apache
and JBoss). E.g. The process will be stopped if the mouse cursor has
been dragged in the command window. In this case, the service can
be resumed by right-clicking the mouse in the command window.
2. How to update the license of Trend Micro ServerProtect?
Ans: Suggest clicking “Update Information” button at left menu
"Administration > Product Registration" after logged on Trend Micro
ServerProtect web page.
