Hello, Thanks to all of uou who have answered my questions on switching to a Linux office, hacking Linux, and so on. As a first step, I think that we will put a Linux box between our DSL modem and our Lan. It will serve as a firewall. Some of you have already answered a question about Linux firewalls and provided examples. The machine will also run an e-mail filter which will look for and remove messages that might contain viruses. Where can I find an example of such a filter, preferably with source code so it can be quickly updated. Later on, we'll be adding things like StarOffice. I'll have both a Linux and a Windows machine on my desk. Thanks. John Computers to Help People, Inc. http://www.chpi.org 825 East Johnson; Madison, WI 53703
