I've fought the same irritating issue now and again. As for
diagnosis, the most useful thing I've found is to turn on full
logging (in ppp.conf), then grep (or tail -f or whatever) the log
looking for the dial trigger after a spurious dial. I'm not on
the machine from which I have the misfortune of needing to use a
modem so I can't say off-hand the exact string to look for, but
it's not any of the four lines you've posted.
If you need more info about the nature of the transaction, try
'tcpdump -i tun0'. I used this recently to determine that various
operations on NAT machines behind my gateway were generating
spurious (and obviously failing) reverse DNS lookups and thus, an
unwanted dial. I never reached a conclusion about how to deal
with this other than to set up a cacheing-only DNS server, but I
shouldn't even mention it here since it's probably not related to
a solution for you (...or is it?)
BTW, and totally unrelated, does anyone know of a graphical dial
utility for ppp(8) (aka, user-ppp?) I see two in the ports
collection for 'pppd', but I know 'user-ppp' slightly better. My
goal is to set up a machine for a completely computer non-literate
friend, and I would rather use FreeBSD than any of the Linux
distros that may also be suitable. I would need to make his
system very user-friendly.
