General Linux Information

What Is Linux?
Linux is a freely available version of unix written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers from across the Internet. Linux aims towards POSIX compliance, and has all of the features you would expect of a modern, fully-fledged unix: true multitasking, virtual memory, shared libraries, demand loading, shared, copy-on-write executables, proper memory management, and tcp/ip networking.

What is TCLUG?
The Twin Cities Linux Users Group is a group of Linux users in the Twin Cities (Minnesota) area. We have monthly meetings in which we discuss various topics releated to Linux. About every 4-5 months we have an InstallFest, which allows new users to get 'a helping hand' while installing Linux. Our mailing list is full of discussions about Linux, hardware, software and everything in between. There is no fee to join the group, and our meetings are open to everyone.

TCLUG Meeting Information

Meeting Information
Meetings are usually held on the first Saturday of the month at noon. We've been fortunate enough to be able to use an industrial sized classroom at the University of Minnesota for past meetings, and will more than likely continue to have access to the room in the near future.

Next TCLUG Meeting
Saturday September 11th from noon until 2pm (due to the holiday weekend on the 4th)

The University of Minnesota. The room is not known at this time.

Topic: Advanced IP Masquerading, ipchains and IP port forwarding.

This will be the sencond part of a 2-part series on IP Masquerading. It will include more advanced techniques and features of IP Masquerading, like port forwarding.

IP Masquerading (also known as Network Address Translation, or NAT) is a way to allow multiple computers to share one internet address. This is great for home use when you have multiple machines that all need access to the internet.

The best parking area is the Washington Avenue parking ramp ($1.50/hour, pay as you leave unless there's a basketball game or other special event, then $5-6 as you enter). There are a few metered spots behind the Radisson that I think are free on the weekend or you can always take you chances in one of the contract lots.A good map of the area is at for an overview of the campus and for a more detailed view.
