TerminatorX v2 can block MSN Messenger and block Windows Live Messenger. It can also:

• block Yahoo Messenger
• block AIM Messenger
• block Web Messengers

• block file sharing (programs and music)
• block Facebook, block MySpace and block Bebo

TerminatorX runs invisibly. When one of your chosen programs or web sites is detected, TerminatorX shuts it down and it disappears.

You can find out who is trying to access banned web sites or programs, by running TerminatorX Monitor - free with TerminatorX - on a System Administrator's remote workstation:

TerminatorX v2 is selective - you can choose to allow MSN Messenger etc. to be used by some users (managers or teachers) but not others (employees or students).

Blocking MSN Messenger port numbers

 

According to Microsoft's web site: "When a session initiation protocol (SIP) solution is used, the data may be sent using TCP, UDP, or Secure Sockets Layer (SSL). SIP signaling can also use dynamic ports, which may require opening the entire range of ports on a firewall."

If users switch to web messengers remember that TerminatorX can block them If they use change to using proxy sites, then TerminatorX can stop them

 

From the same source, some of MSN Messenger ports are:

• Audio and Video - dynamic ports were chosen for the audio-video (AV) stream.... using dynamically allocated UDP ports in the range of 5004 to 65535.
• Application Sharing and Whiteboard - whiteboard (WB) data uses port 1503...
• File Transfer - Both incoming and outgoing TCP connections use the range of ports from 6891 to 6900...
• Remote Assistance - TCP port 3389 is used for the TCP connection for the Remote Assistance protocol.

 

Other sources

The MSN Messenger port numbers below are taken from (amongst others) PortForward.com and Experts Exchange discussions Q20968914 and Q20660861.

Unfortunately, trying to block MSN Messenger ports doesn't work because of the wide range of ports including port 80 that MSN Messenger uses:

• TCP port 80 (the 'http' standard web port - see also Web Messenger blocking)
• TCP port 1863
• TCP port 6901 (possibly)
• TCP ports 6891 to 6900.
• UDP on ports 1503, 3389, 5004-65535

Blocking port 80 removes web browser Internet access.

Also, users will just access MSN Web Messenger and other web messengers

Further information is available from this forum (in German):

"Ports 6891-6900 enable File send,
Port 6901 is for voice communications. Allows Voice, PC to Phone, Messages, and Full File transfer capabilities.
IN TCP 6891 - 6900
IN TCP 1863
IN UDP 1863
IN UDP 5190
IN UDP 6901
IN TCP 6901"

Other information from www.cyberphaze.net (not currently online) gave:

Service: remote: 1963 and 1863   local: 1542 and 1493.
Audio: local: 13803, 1556, 11771
File transfer: remote: 6891   local: 1544
Messenger Update: remote: 80 local: 1457
Sign-In: remote: 443 local: 1484, 2400
Remote Desktop: local/remote: 389, 522, 1503, 1720, and 1731.
