Hi all,

I'm trying to use tshark display filter "-R" to show camel part of my pcap file (sybsystem number is 146). Although it can be done by modify the camel "TCAP SSNs" range in wireshark, I could not find a way to modify the range of SSN in tshark.

the command I tried is like following:

tshark -V -R ",camel," -r inputfile.pcap

or  tshark -V -R ",sccp.ssn > 6 " -r inputfile.pcap

 

I have searched in wireshark website, and in http://wiki.wireshark.org/CAMEL

it said "The ssn used to dissect CAMEL is configurable." however where to configure it?

 

below is what I get from tshark, the camel part is not readable.
