Wireshark-dev: Re: [Wireshark-dev] filter expression required

A pcap filter? You mean a capture file? The pcap/capture filter syntax does not provide a 'contains' keyword, so it's not possible. You can only use 'contains' in the display filter syntax, which is unique to wireshark (and tshark, etc.)

i need to give filter expressions defined by pcap, but i am not getting any documentation of it.

Re: [Wireshark-dev] filter _expression_ required







You're really using the "contains" keyword? That's for strings and
binary strings.

The spaces in your filter are probably confusing the shell when you
invoke wireshark/tshark from the command-line. Are you running on
Unix? Use single quotes around your filter:

tshark ............ 'udp contains xxx'
