Title: A question about ASN.1 encoding in wireshark

Hi,

 

Thank you very much, I can build my dissector successfuly,

 

Do you know how to debug wireshark? I installed DDD on my platform. I want to track the code when running the application.

 

By the way, I edit an ASN.1 message by ASN1VE, and tried to open it by wireshark but it still can not decode the message correctly(can not show the field name correctly). Is it right I open my ASN.1 based message directly by wirshark? or I shall capture the TCP based ASN1 message I defined, then open by wireshark?

 

Best Regards,

Chris

Hi,

You need to copy the resulting packet-clip.c and .h to /epan/dissectors and edit the makefile.common in that directory. NOTE there is already a dissector called clip

presumably for something entierly different. You may want to change the name of your dissector...

Best regards

Anders

Hi,

 

Thank you,

 

I used command "python ../../tools/asn2wrs.py -p clip -c clip.cnf -s packet-clip-template clip.asn" to build my dissector. Then I recompile the wireshark, it is still not work, did I missed some steps? or arethere any guildines or tips when write .cnf file and template files?

 

Regards,

Chris

Hi,

 

if it is BER encoded and you need only to display it (withou any additional handling) the other possibility could be the ASN.1 plugin.

As I know it requires  only precompiled ASN.1 description.

But I have never used it.

Hi,

Do you get anything displayed after TCP?

See http://wiki.wireshark.org/Asn2wrs on how to design an asn1 based dissector using asn2wrs.

 

Best regards

Hi All,

I have a question about ASN.1 decoding in wirshark, hope can get someone's help.

I have my own defined ASN.1 messages, these messages are decoded with BER, the messages transfer based on TCP/IP, wireshark can capture the messages, and decode the message, but can not display the field name in the detailed information area.

I want to add my ASN.1 definitions in wireshark, and can decode/show the message correctly in the detailed information area in the wireshark, but I do not know how to proceed, it there any one can share the experiences or send me some useful materials?

Thank you very much,

Chris
