After some more digging around and a lucky hunch I tried
insmod 3c59x
and got the card working.
When I ran pppoeconf it asked me whether I wanted it to automatically
open a connection at boot time. I said no, so it said I can start the
connection with:
pon dsl-provider
and stop it with:
poff
That works, but I have to open a shell window and su as root to execute
either command.
I am uneasy about being temporarily logged in as root in order to
start/stop DSL connections.
Any suggestions of a more secure and elegant method of start/stopping
DSL connections?
