Wireshark · Wireshark-dev: Re: [Wireshark-dev] Including ASN.1 format coding in a C dissector

[<taraniteja.vishwanatha@xxxxxxxxx>]

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??
