How do you dial up now? Does it just do it on-demand or ?? There are two ways this is usually implemented: 1) A program called `ppp' runs with the -alias option which takes care of dial-up and address translation. 2) A daemon called `pppd' runs which takes care of dialup and translation. You just have to find where these are started, remove them, then use `kill' to kill them. > 2) How do I stop it from performing IP translation? See #1. > 3) Is there any GUI interface that can help me manage this machine in > it's mail serving capacity? Unfortunately, no. How do people get mail off the machine? using POP (Eudora, Netscape, etc) or just log in directly? If the accounts are on the machine, you can use the adduser/rmuser commands to add and remove users, respectively. Hope this helps.
