/proc/<number>/cmdline is supposed to contain the command that
started the process whose process id is <number>. The error message is
not saying there was anything wrong with the command, but rather that
the command didn't get written into that location. I doubt that this is
your main problem, because the log indicates that pppd started up ok.

This is the trouble. Your machine is sending out a request and not
getting an acknowledgement. I am far from being an expert on this
stuff, but I've read a certain amount of documentation and
correspondence while trying to get it working for myself, and I've seen
people say that some ISPs don't like to receive the <mru 1500> in these
lines, and that problems have gone away when it is removed. So if "mru
1500" occurs in either your /etc/ppp/options or the ppp-on script, you
could try taking it out. You aren't (yet) having chap authentication
problems - the negotiation isn't getting far enough for that.

That's ok. The debug output is going to daemon.log. If you read enough
syslog and pppd man pages you can figure out why and change it if you
care.
