David,

 

Can you provide us with a PCAP that contains a few of these packets?

Subject: [Wireshark-users] Help with tshark display filter

 

I need to scan through several hundred capture files and pull out all of the 9 character ID’s on certain request packets.

 

I’m using the following tshark command:  tshark -r cfile0001.cap -R "data contains NETN" -Tfields -edata

 

However, I cannot find a way in tshark to get this to output as text, only as a byte array.  I’ve tried –edata-text-lines, and various other things from the tshark man page, but so far no luck.   I just need to display the data as ascii text…….

 

Ideally, I would like to extract the ID’s that are at a fixed byte offset..  I tried –edata[66:9] but this displayed only blank lines……..

 

Any help would be much appreciated!

 

 

David
