Hi everybody, This is a reminder about the upcoming WLUG meeting, to be held in Kinnicutt Hall (a.k.a the usual place) at WPI at 7:00 PM on Wednesday, May 16h. The topic for discussion will be the practical use of IPCHAINS. What does that mean? This meeting, Doug Waud and I will present to you ways to use IPCHAINS to implement a firewall. This is not theory, this is practice...what to type, what it does, and why. This talk will build on the more detailed information presented by Bob Ziegler at our last meeting. Doug will start with a presentation of the simpler case of getting a firewall up which supports masquerading (that is, getting multiple machines on your home network to share one IP address, as you would for cable modem, for example), e-mail, and browsing. I will follow up with more detailed examples of IPCHAINS code from my own firewall script for allowing certain services through the firewall to the home network. Although firewalling is a complex topic, we're hoping to distill out of that complexity enough information so that a person can get started toward implementing a secure firewall. I'm looking forward to a good turnout at this meeting. Come on down! Later, Andy -- Andy Stewart, Founder Worcester Linux Users' Group Worcester, MA USA http://www.wlug.org
