Hello Everyone,
Can someone guide me on how do i block Yahoo Messengers, in the Intranet,
Lab. I have a Win2k server & also a Linux Server [with Squid & IP Chains] as
the gateway.
I found this on Google for AOL & ICQ and MSN.
#AOL Instant Messenger
ipchains -A input -s 0/0 -d 0/0 5190 -p tcp -j DENY
ipchains -A input -s 0/0 -d 0/0 5190 -p udp -j DENY
#ICQ
ipchains -A input -s 0/0 -d 0/0 4000 -p tcp -j DENY
ipchains -A input -s 0/0 -d 0/0 4000 -p udp -j DENY
#Microsoft Instant Messenger
ipchains -A input -s 0/0 -d 0/0 1863 -p tcp -j DENY
ipchains -A input -s 0/0 -d 0/0 1863 -p udp -j DENY
Please guide me about how to make COMPLETE block to Yahoo Messenger.
Any pointers will be helpful.
Thanks in Advance.
