TCPDump Question

What is the correct format to export a dumpfile to, to be properly read in wireshark? I am having issues with wireshark complaining about my capture files not being valid.

It sounds like you may be redirecting the text output to a file, which is not what Wireshark wants. Tcpdump can write the packet data to a file in PCAP format. Use the -w option, then you can import that into Wireshar.
