[ubuntu-za] Ubuntu Beginner

[Gareth McNaughton]

Hi there

I have been using windows since its inception so I am, I think, 
reasonably at home with windows and all of its programs etc.

Some time ago I updated to Vista and as a result became totally 
********** off with the system. So I have obtained a copy of Ubuntu 9.04 
Desktop Edition from Canonical and have installed it on a spare PC which 
has XP installed. I chose to install Ubuntu inside windows as I didn't 
want to clean the PC just yet.

The PC is a P4 Celeron with 1m Ram, 80meg HD and DVD. I use Iburst 
Wireless to connect to the Internet via UTD Desktop Modem.

I have loaded Ubunu with out any problem and those programs that were 
installed by default seems to run OK. However I cannot get the modem to 
connect, in fact I'm not sure if the modem is recognised. From searches 
on the net, from my main PC, it seems that the Modem should use the 
RJ45(ethernet) connection rather than the USB. I have changed from USB 
to RJ45 and I am still able to connect to the Web via windows so the 
modem connection is working.
 From the “How to” directory on the Wiki.Ubuntu-za web site I have read 
the article on setting up an Iburst modem on Ubuntu _Intrepid._ Is 
Intrepid the same as 9.04 and are the instructions still valid?


I realise that the Linux systems use a completely different approach 
than windows so I am struggling to understand some of the commands which 
seem to be simialar to Windows Command line instructions. For instance 
in the Iburst Modem How To set up, it says - “sudo apt-get install 
linux-headers-2.6.27-7-generic'.


Question: from where do I do this command?


Any help would be gratefully accepted.
