I tried using -XX and -s1500 like it was advised by Peter, but the problem persists : I have the content of the PPP Compressed packets, but I haven't the content of the RTP packets not compressed. My work consists on compressing a video stream before sending it and I capture the packets to analys

You do not have "all the details" with ethereal. That's because you are *telling* tcpdump not to sniff them. You are instructing it to take just the headers with the '-s' switch (zero payload: -s0). Try 1500 instead of 0 and you will get what you desire. -- Peter --- bannour souha <[EMAIL PR

Hello, I am working on PPPoE. I use FreeBSD 5.3. I want to capture packets from the interfaces eth and ppp. I used for that this command "tcpdump -e -i rl0 -n -s0 -w /home/dump_eth" when I analyse the packets with ethereal, I have all details, but when I read the content of the file "dump_eth

I am running FreeBSD 3.4 with the GENERIC kernel which has the line "pseudo-device bpfilter 1" uncommented in the config. I also re-built and re-installed GENERIC just to be sure. /dev/bpf0 has "rw" permissions for the owner (root). There are no other bpf devices in /dev. When I su to root and r
