OK.  Here's how it goes.
I disabled eth0:  ifconfig eth0 down
and then adsl-start worked. =20
So I used Internet Configuration Wizard, entered my hostname and disabled=
=20
eth0.  Rebooted.  Now eth0 didn't show up in ifconfig's output, only the =
lo=20
interface.  So far so good.

Then I did the ol adsl-start.  That brought the network up and got me=20
connected.  ddclient then sent root an email saying that my domain info w=
as=20
now updated.  Also good.  I typed hostname -i and got the newly assigned =
ip=20
addy.  Then 'hostname' reported my proper hostname and not localhost.

Then I fiddled and fscked with sendmail to no avail.  I ended up complete=
ly=20
wiping it from the drive and built postfix, installed and configured it. =
=20
(First I tried rpms, but that was feckless--I didn't see postfix rpms on =
the=20
YDL mirrors, btw).
After configuring postfix, I ran postfix check.  There were some permissi=
ons=20
problems that I had to fix.  Still didn't work because I ended up rpm -e'=
ing=20
sendmail, which removed quite a few /etc files, alias files and whatnot. =
 So=20
I ckecked maillog and found the problems fairly quickly.  Copied files to=
=20
where they belonged, adjusted a few more parameters in main.cf and voila!
email works!  pppoe works.

Now:  anyone have a good howto on sharing this internet connection with m=
y=20
eMac?  And a good iptables/firewalling how-to?  I haven't looked at all y=
et=20
and I'm sure they're out there.  But I had enough for one day.

Thanks again,
