Overview During troubleshooting, you might find it useful to determine what is happening on the wire. While tcpdump is a great tool for capturing packets, it's does not offer the same level of filtering capability as tshark. While it may be easier to simply copy a capture file locally and use wireshark, sometimes restrictions prevent this approach. Capture and Save with tcpdump Capturing and saving to disk is my favorite way to review wire traffic.
