pppoe, pppd and dsl problem on Woody

[<ryan@ramona.phys.uaf.edu>]

I used pppoeconf to set up.  It found eth0 and my Access Concentrator.
When I started with 'pon dsl-provider', I got the following error in
plog:

Feb 18 10:07:57 myname pppd[495]: pppd 2.4.1 started by root, uid 0
Feb 18 10:07:57 myname pppd[495]: Couldn't set tty to PPP discipline: Invalid argument

My /etc/ppp/peers/dsl-provider file reads:

pty "/usr/sbin/pppoe -I eth0 -T 80 -m 1452"
noauth
defaultroute
user "myusername@myprovider.net"
usepeerdns

My /etc/network/interfaces file reads:

auto eth0
iface eth0 inet ppp
     provider dsl-provider


Any ideas?
