I got the network set up, to a point.
The problerm was that eth0 was and still is getting started at boot.  I 
have to mark it 'down' and then adsl-start works and I can get through 
to the world.  But...

right.  But this weird.  trying to set the hostname works, but when I 
reboot it's lost.
See, it's that second line:  192.168 etc... that I wonder about.
I know that I need to enter my 'praeclara.com' name there.  But what IP 
addy do I enter?
My addy is assigned dynamically via pppoe.  But I have custom dyndns, 
which always points my domain name to my current, real ip addy.

And I think this is causing my sendmail probs.  I can send mail, but I 
can't receive it.  I think it may be because the default network device 
is eth0 and maybe it should be ppp0 (or something else).  And I don't 
have a clue about how to change that.  All this stuff is done 
automagically behind the scenes, it seems, and I don't know what to 
even try...

When I check my /var/log/messages and maillog, I see absolutely nothing 
irregular.  Nothing.  Just no sign of incoming messages.

And like I said, I think that's because this hostname and default 
network device issue.

Any ideas how to proceed?  I'm sooo close.  All i'll have to do after 
sendmail is set up ipmasquerading, imapd and I'll be golden!

Thanks again,
Jeff
