Unix IS user friendly... It's just selective about who its friends are.

many thanks Zeb fro the response

but may be u overlooked my 1st question that where to go to block these ports also can i specify that for which users to block these ports.

as if i see in LAN tcp/ip properties it gives the facility to specify which one to allow but not for those to be blocked.

thanks

Are you trying to block the ports from LAN users or the internet?

If the latter, you might consider a hardware firewall/router as an option. There are also various software firewalls available such as Kerio.

If you're blocking ports from all computers, it's under TCP/IP Properties->Advanced->Options->IP Filtering
