analyze traffic remotely over ssh w/ wireshark

This captures traffic on a remote machine with tshark, sends the raw pcap data over the ssh link, and displays it in wireshark. Hitting ctrl+C will stop the capture and unfortunately close your wireshark window. This can be worked-around by passing -c # to tshark to only capture a certain # of packets, or redirecting the data through a named pipe rather than piping directly from ssh to wireshark. I recommend filtering as much as you can in the tshark command to conserve bandwidth. tshark can be replaced with tcpdump thusly:

ssh root@example.com tcpdump -w - 'port !22' | wireshark -k -i -

Sniffing network to generate a pcap file in CLI mode on a remote host and open it via local Wireshark ( GUI ).

Then hit ^C to stop, get the file by scp, and you can now use wireshark like this :

wireshark /tmp/sniff.pcap

If you have tshark on remote host, you could use that :

wireshark -k -i <(ssh -l root <REMOTE HOST> tshark -w - not tcp port 22)

The last snippet comes from http://wiki.wireshark.org/CaptureSetup/Pipes
