I use open SUSE 11.3 and want to connect to the Internet but I can't configure out how to do it, any help is previously appreciated.
@chris is very correct. there is little point doing it yourself in linux especially if you have to ask (sorry if I sound rude).
However, for the matter, run yast -> network service -> DSL
or you need to download roaring-penguin PPPoE client:
Compile it, then run adsl-setup, adsl-start (to connect) and adsl-stop (to disconnect).
The simplest way is to connect your computer to a router, and hook up the router to the DSL modem. You can either configure your computer to use DHCP, or hard-code an IP address.
I do remember in the "bad old days" when you had to run software on your desktop to talk to the modem, but I'm pretty those days are gone.
