[LBo] new system setup, progress and questions

[Ray]

Hello all,
Well this has been a learning experience. I've finally got my linux system up 
and running. (Kubuntu 6.10, now as well as an ugly hardware hack to get the 
charging system working.) This email is being sent from Kmail, instead of 
Outlook Express so I guess it's kind of a test email too. 
Thanks to all who helped me with my wireless network card. Many of your 
suggestions didn't work properly with KDE and/or Kubuntu, but you pointed me 
in the right direction and I found a good write up in the Kubuntu forums. 
I would like to ask a little more about networking in Linux.  at the moment, I 
can see available wireless networks with this system, but I can't connect, 
(WEP, or open, no difference) Any suggestions, or pointers? Also, If I don't 
have a network cable plugged in on power up, I can't connect by a hardwired 
connection. Is this a configuration issue, or a Linux issue?
The next question I have is regarding the course.
exercise section 2.5.4 refers to a file /etc/inittab  which I can't seem to 
find. Is this a distribution specific name or location or am I blind?
TIA
Ray
