Hi,

i’m expanding the features oft he PTP Dissector, but i wanted to know if there is a way to read a external config file for the dissector.

The dissector would need some keys to check if the packets are valid or not (it’s about the ICV checksum).

 

Should I just try to add the reading of the config file to the dissector or is there a better solution. (I think it’s a bad solution because it would read the config file every time a packet is received)

 

Also, is there any argument against calculating a SHA1 / SHA2 hash in the dissector routine?

 

I tried to search google for a solution, but I didn’t find something.

 

At last, is there somewhere a function reference for the dissector plugins (like proto_tree_add_item and so)

 

Regards
Thomas
