Hello,

I have installed ethereal (rpm for 0.6.1-1) on a RedHat5.2 linux box, in
order to trace some ppp stuff. Actually, the ppp data is captured by
tcpdump whenever ppp0 is up.

I have read that ethereal is able to read "packet data from a pcap/tcpdump
formatted capture file" (from the man file). but when I launch 
ethereal -r trace.txt
(where trace.txt i sthe result of 'tcpdump -l -i ppp0 -x -s200 -v')
ethereal barfs out that it can't load the file...

does anybody have a clue regarding the format of a "tcpdump data dump
file" because neither man files (ethereal's, tcpdump's or pcap's) is very
clear on the subject.

thnaks in advace.
