Hi,

You can use text2pcap but you still need to code the message your self unless you have some sample

Messages you can paste together. Like RANAP messages from some other trace with the IE:s your after.

Best regards

Anders

Hi Anders,

 

Thanks for the information. The dissector is propreitary , hence I cant include it in Wireshark.

 

I will include RANAP messages in the way you have mentioned.

But then , I will have a tough time forming packets for testing . Any clue how can I form the packets.

 

Thanks in advance.

 

Regards,

Tarani

Subject: Including ASN.1 format coding in a C dissector

 

Hi ,

 

I have written  a dissector for a protocol which has a coding standard of Tag-Length-Value. Now in this dissector , I have to add some messages of RANAP protocol which has a coding standard in ASN.1 format.Already the dissector for RANAP is available in the wireshark. Now:

 

1.Can I call the existing dissector for those particular messages??? If so how do I do that??

2. If I want to include it normally in my dissector, how can I convert the ASN.1 format to obtain the tag and lengths of  individual parameters??

 

Can anybody please help??
