Anyway, so you'd say I am a freak and I installed ubuntu at my home. No one else would. Well, no I know a few more guys who do use nothing but linux. But the point now I wanna make is, Linux is at your homes, maybe without you knowing it. yeah! Like in my case I got down this ADSL router. This is a common device for the offices and homes now. The chance is, if you own one then you are having linux at your home/office (like it or not). Yeah this baby run on linux and acts as your firewall/gateway and AP. Its got an easy to use web interface for you to set things up and works good. If you wanna play around more you can telnet to the box, and can do a lot more.
If you do a version check on the device it should get you something like this.
Linux version 2.4.17_mvl21-malta-mips_fp_le (email@example.com) (gcc version 2.95.3 20010315 (release/MontaVista)) #60 Wed Nov 10 09:49:30 CST 2004
