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.

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 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
