Displaying / filtering IPv6 ICMP types and codes

Hey Ken,
Argus has been doing the V6 thing for an amazingly long time, the first implementations being done before some of the ICMP messages were created.  We haven’t put a lot of effort into V6 because there has not been that much dialog around it, so the implementation is not complete.

OK, with that said, the type and code fields are in the flow record, but there maybe some gaps in how those are aggregated, processed and printed.  Which we can and will fix.

So, can you give me some specifics on what is needed ??  Do you have any records where you know what they should print, and how you would want them printed ???  Can you share the argus file of those records ??  That way we can have something concrete to talk about ….

Sorry for any inconvenience,

Carter

The default display shows the Type in the Sport field, and a text summary code in the State field.  Perhaps the Code is included in the Dport field, but it always seems to be 0.
