[wellylug] Configuring a Telstraclear cable modem with Suse9.2

[smahoney at tpg.com.au]

Quoting pmilne at paradise.net.nz:
Thanks for that-but my knowledge might not be as good as you give me credit for!
I entered the line

ifconfig 207.xxx.xx.xx netmask 255.255.255.252 eth0 up

and then checked what ifconfig indicated  and it had taken the new details- but I was still not able 
to fire up the browser- no luck. When I rebooted I was back to the old netmask of 255.255.255.0.

I connect by ethernet cable.
If you asume my knowledge is next to zero when it comes to doing this- from the moment I plug 
in the ethernet cable and fire up the box- what commands do I need to enter to get internet 
access.
Happy to print out any logs or output if that would help.

cheers
SteveM
