/var/log/syslog and /var/log/debug will probably hold the most
debugging info.

These are showing the keepalive packets that are being sent by the
ppp link. The fact that they are being sent & received means that
some PPP connection exists. Does this server have a link to the
outside world using PPP? If so, that might be what is generating
these messages.

Dial into the remote machine with minicom on linux or hyperterminal
and see what you get. Something along the lines of:

-> ATZDT<insert phone number>
*pause*
<- CONNECT

If ppp is started instantly, then you'll see some garbage that
starts like "~ÿ}#À!}!}!} }4}". And if you've gotten this far there
should definitely be more info in the /var/log/syslog or debug.

Regards,

Bernard.
