What is the best way to start logging tcp traffic once a ppp link has been
bought up by pppd?
What I want to do is start:
tcpdump -i ppp0 -w somefileorother
immediately after the ppp link is established.
The machine I want this to run on, is acting as a test ppp dialin sever.
I had a go at adding "record logfile" to the pppd options, but
unfortunately, when I run this through tcpdump, it barfs. I want a logfile
which can be read by tcpdump, and ultimately ethereal.
