Pass.  Your ISP may well have a couple lying around.  Consult their dns.  :-)

Not that simple.  If you only ever run ppp as root, then fine, it will
work.  If (like me) you run ppp as a lowly user, then it won't work
because it will be running with non-root privs.  The correct answer is
to write a setuid wrapper (not always a terribly easy solution...) or to
do what I do which is to correct my clock about once a month (when I
remember by doing "sudo ntpdate ntphost1 ntphost2 ntphost" or whatever.
If you don't already have sudo installed, it's probably a worthwhile
download.
