I'm a newbie in UNIX system, and I must do some IP and port blocking... (ex: www.hotmail.com or yahoomessenger)
How is the best way to do that?!
If anyone could give me a step by step help!
thanks
Blocking IP addresses depends on the platform doing the blocking. You need to provide specific platform information ......
I'm using a LINUX environment ( Conectiva 7.0) , with a proxy server... and all clients are windows (98. NT, 2000).
I've tried some changes at squid.conf but it didn't work.
I intend in blocking a few websites and ICQ, YAhooMessenger, and therefor...
I hope I made myself clear this time 
thanks

I'm using the proxy! It's all configured there... my proxy does everything.
Squid, as an HTTP proxy server, can be configured to block IP addresses and web sites. Try visiting the squid web site for docs:
The specific details for squid ACLs (access control lists) may be found here:
