I fear this is a bit more complicated than I had intended.

There's no need to do this unless the NIC isn't
recognized. ls '#l' (that's an ell after the sharp)
and if you see a directory named ether0 you're
already all set. Alternately grep ether /dev/kmesg.
In particular, an i82557 should always be recognized.
Only old ISA cards need these lines anymore.

These entries are only necessary if you don't like the DNS
servers that the remote PPP server is suggesting or if you
have other things on the network besides the PPP modem
(unlikely). In the common case, you just run ip/pppoe -P
and that sets up /net/ndb with the info from the remote
PPP server.

You only need to reboot if you edited plan9.ini
because the kernel didn't recognize your ethernet
card (see above).

You only need one of these lines. It doesn't matter which one.
And you can write '#l' for '#l0' if you're so inclined.

Saying ether0 isn't necessary -- that's the default.
Saying -d isn't necessary either, but it does print potentially
useful debugging info. In most cases you want the -P flag (see above).
So "ip/pppoe -dP".

Cs is already running (started in termrc/cpurc) and need not be run again.
> ndb/dns -r
DNS is also already running and should not need to be run again.
(I say should not because in times long past it was sometimes necessary.)
You should be able to just
echo refresh >/net/cs
echo refresh >/net/dns
and be all set. I just changed ppp (invoked by pppoe) to do this
for you, so if you pull binaries tomorrow, these shouldn't be necessary
either. Writing to /net/cs is just a custom anyway -- nothing cs cares
about (the list of available protocols inside /net) has changed.
So the simpler version of how to run pppoe, similar to the one in
http://lists.cse.psu.edu/archives/9fans/2001-October/013562.html,
is to run
ip/pppoe -dP
echo refresh >/net/cs
echo refresh >/net/dns
and the last two commands should go away soon enough.
