Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have configured Zerina OpenVPN 0.9.5b on IPCop 1.4.18 firewall. I set it up as per the "how to" guide on the zerina site, and added an internal route to my vpn host server.
On my Windows XP client systems I am running OpenVPN gui V1.0.3.
At first everyhting was OK but after a few days the clients started dropping the connection after about 5 seconds. They now do this reliably every time. There are no errors displayed in either the client or server logs - the client and OpenVPN server both say they are still connected (green). Nothing has been changed on any of the servers, firewall, or clients (no patches or service packs added). Pinging the Green subnet or OpenVPN subnet gateway (e.g.10.10.10.1) works OK for around 5 seconds and then I get "TTL expired in transit"
I rebuilt both IPCop server and client machines and they still have exactly the same problem!
The really anoying thing was that it all worked perfectly to start off with!
Has anyone else any ideas, or had this problem (and solved it)?
Many thanks in advance...
