Thanks for the pointers. I'll have to look into it.

Wow. Now i see a /etc/conf.modules! I was looking for all the *.conf
files, but didn't see that one. On the other hand, there's no man page
for that either.

What #hash line?

Excellent. I didn't know about that one either.

This one is fine.

Two more i didn't know about! Is there a book about administration or
networking that teaches these things? I read a few books a couple of
years ago and those tools were not mentioned.

Well, despite the fact that i'm getting duplicates of all the e-mail
to the debian-users list, you may not have seen the one that says i
"fixed" this. It only happens when booting. I created an S14network which
restarted things, but then it was still turned off. So someone else
proposed it and i changed it to S98network and now the timing works. The
network comes up (as noted by a ping from another machine), then it goes
down and then the S98 kicks in and it stays up.
Thanks again for all your help. This is very useful information and i
really appreciate it.
