This is new ! if you don't choose server (in the installation) you wont get inetd. They even splint the telnet package to two: server/client. But when im installing server, its does not give me the option window if I want X or Gnome. Arie Vayner wrote: > Hi > > I have the file, and it's just fi

This is getting to be a circus ! You CAN NOT run a firewall when ip-forwarding is disabled ! the basic thing about a firewall is that it forwards packets, althought applaying some sort of restriction at the forwarding rules. Read the howto again .. both of you. At this (Wed, Apr 05, 2000 at 12:5
