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 -
When using tcpdump, specify -U option to prevent buffering.

dsniff is general purpose password sniffer, it handles *lots* of different protocols, but it also handles tcp-style expressions for limiting analyzed traffic - so I can limit it to work on pop3 only. Show Sample Output
The command is useful for monitoring the use of the boxes and their connection IP. Result file "sniff" is readable with GUI program "wireshark" or through CLI with the command: tcpdump -f "sniff" -XX Show Sample Output
analyze traffic remotely over ssh w/ wireshark When using tcpdump, specify -U option to prevent buffering and -iany to see all interfaces. Show Sample Output
Replace servername with your user. And make sure you have generated / copied your rsa_pub key to the remote server, or you will be asked for a password which will stuff up the output to wireshark.

This allows you to display the wireshark program running on remote pc to your local pc.
