...not sure, but the other month when I had similar problems I noticed
that "tcpdump -i" was of no use as the interface wasn't up yet so
tcpdump didn't monitor the ppp line, or the line was up and ready
allright but the culprit of bringing it up had vanished before I could
type tcpdump:( IIRC I switched off demand dailing temporarily, brought
up ppp, started tcpdump and waited for 15 minutes, and bingo: DNS:)
