Wireshark-users: [Wireshark-users] Parsing Diameter Parameters AVP

I’m trying to parse the data from a group of Diameter packets.

 

I enter the command:

tshark -r mypackets.cap -T fields -e frame.number -e ip.src -e diameter.hopbyhopid -e diameter.avp | head

It returns the output:

Running as user "root" and group "root". This could be dangerous.

For the frame.number and diameter.hopbyhopid fields, it gives the correct output in desired  format .  For diameter.avp, it does not.

The returned format is currently

-          in binary format.

-          if I have multiple AVPS on a single packet, only the last AVP data is presented

        for example for packet number 1 there are 3 AVPs but we only receive data only for the last one

I also add dictionary files and when I use –V option it then returns the AVP data correctly (shown below)

    AVP: Origin-Host(264) l=26 f=-M- val=sde38.sandvine.com

    AVP: Result-Code(268) l=12 f=-M- val=DIAMETER_SUCCESS (2001)

    AVP: Origin-Realm(296) l=20 f=-M- val=sandvine.com

    AVP: Origin-State-Id(278) l=12 f=-M- val=1264342612

 

 

Does anyone have any idea how I can receive all the AVP fields, and for them to be presented as text (not binary)???
