Guerilla penguin
I did take on a biggy. Install a Linux OS and get it running on my p.c. wirelessly. Now accomplished. Sort of. For those of you who are not close to the penguin Linux is a multi-flavoured Open Source (the important bit is FREE here) operating system, a more secure, and apparently stable alternative to Windows. It's constantly in development so bugs and issues get fixed quickly and the way Linux works means you don't normally need a firewall or anti-virus program. The only problem is that hardware manufacturers don't do a lot to support Linux users in terms of drivers so there are all sorts of workarounds. I know this because I must have spent the equivalent of 20 hours pouring over forum threads about wireless networking to get my own (albeit obscure) wireless USB adapter working. It set up a wired LAN network automatically but wireless.....that's a bit different. And I still haven't been able to get it configured with security enabled. But I will, eventually.
So, if you're one of my neighbours and have attached yourself to my network (I know who you are)..... that wasn't me earlier looking at pictures of naked Australian women, but yes, they were tasteful. And that wasn't my bank account I was checking either. If I were you though I'd batten down the hatches because thanks to Linux I've just discovered two open source cracking utilities that'll mean I'll be able to unzip your WEP key post haste. You better hope you don't have any "artistic" pics of your wife on your hard drive.
Viva la penguin!
