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'm concerned with the security of my wireless LAN in my apartment. i haven't managed to set any encryption up yet, as i am quite confused with how to do it under hostap (i have a netgear 311A acting as an AP). from what i have read about the WEP that's available i am to understand it is quite insecure. for this reason i'm now interested in a VPN over wireless (screw the WEP), but have no clue where to start reading.
my mail goal is to increase my wireless security, which is currently at about nil. any suggestions on where to start would be awesome.
i can't stop thinking about ninjas and thx for reading,
Distribution: FreeBSD,Debian, RH, ok well most of em...
there are a few solutions available but I found the easiest for me was to firewall off the AP allowing only the specified MAC addresses of my cards. I check the logs for strange attempts, times, etc. I figure if someone has enough time and skill to forge MAC addresses I have other things to be concerned with. Plus I think I would notice someone parked out front that long or the dogs would chase 'em down.
cyph, i've already set the MAC matching on my router/firewall, but there is the issue of my living in an apartment building... i'm to understand that MACs and IPs are sent as plaintext on a wireless network, so that if anyone is listening w/ kismet, etc., they can sniff the MACs and jack my wireless connection. and based on the spatial considerations in the building, that's just about anybody with a laptop.
if i had more space (like cyph), i wouldn't be as concerned. it's still a fun game though: how locked down can i make my security setup? it's a personal challenge of sorts, and since i've stopped playing video games, this is what i'm up to .
are you trying to make sure nobody reads your traffic or that nobody gains access to your router and browses the web for free? If former, then just use VPN and segment it on a separate DMZ. If latter, then you're out of luck. It takes 1.45 seconds to change a mac address. Even less to discover a list of macs allowed with kismet/Airopeek.
