Title: A question about ASN.1 encoding in wireshark

I added a new page to the wiki with the complete sample code and linked it to the Asn2wrs page.

HTH,

 

Jacob

Hi Jacob,

 

That would be very great if you can post your example on the web page, or send the the example to me by emal, that would be very helpful for a new user who is trying to make a new ASN1 based dissector.

 

Thank you very much,

Chris

Hi,

 

I was struggling with the same issue a couple of days ago, as it wasn't clear from reading

other dissectors what needs to be done.

So I wrote a very basic dissector that dissects UDP packets off a curtain port and are ASN1 encoded

with a couple of fields.

I think that such an example could be useful under the asn1 directory.

Let me know if you want me to post it and how to post it.

 

Jacob

Hi,

You have to write a dissector for your protocol and have it register for the TCP port used in order to have the protocol dissected.

Hi,

 

I made a ASN1 based message on TCP, but could not get anything displayed after TCP in wireshark. by default it used ENTTEC after TCP.

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

Anders

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
