Wireshark-dev: Re: [Wireshark-dev] 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. http://wiki.wireshark.org/FooPage HTH, Jacob From:

On Behalf Of chris.guo@xxxxxxxxx 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 From:

Behalf Of ext Jacob Avraham 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 From:

Behalf Of Anders Broman (AL/EAB) 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. Brg Anders From:

Behalf Of chris.guo@xxxxxxxxx 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. From:

Behalf Of ext Anders Broman (AL/EAB) 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 From:

Behalf Of chris.guo@xxxxxxxxx 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 |
