Hi Oleg,

I have played with the SCTP code you sent and have some comments:
1. How much sense does it make to have SCTP conversations?
   I'm wondering, because for UDP or TCP this corresponds to
   a TCP connection or a UDP communication relation. But for
   SCTP it has no sense, since SCTP associations are multihomed.
   Guy, what do you mean?
2. If the user specifies a display filter for an association
   you provide a statistic for the chunks. Currently on the last
   chunk within each packet matching the display filter is counted.
   How do you use this feature? Do you need this counter per
   association for each direction separately or do you
   use also other filters? We could integrate such a statistic
   in the SCTP analysis window which shows information per association.

Best regards
Michael

Hi,

With regards to SCTP stat. I think it's great that you already have
something.
We will start using it as soon as you publish it.

It just currently we in the middle of the testing some big project that
includes SCTP measurement stuff and
I found it very useful for our testers instead of struggle with bunch of 
filters just get all information in one shot.

Guy,
Another question is AgentX dissector.
I sent the tarball and I'd like a to get some comments on it also.

Thanks,
Oleg.

Sorry for the wrong subject in the prev. message.


Hi,
I'd like contribute another work to ethereal community.

1) I've added some statistics to SCTP.
   tap-sctp.tgz contains the following:

   gtk/sctp_stat.c - contains SCTP stat. GUI
   tap-sctpstat.c  - tethereal variant of the same stat.
   gtk/conversation_sctp.c - impl. of SCTP conversation info.
tap-sctp.patch - has a changes for packet-sctp.[hc] and tap-iousers.c 
and also for list of CM files
   in order to support sctp stat and AgentX plug-in.

2) Plug-in dissector for AgentX protocol.

I've tested it on Linux RHAS 3.0 It builds and executes fine.

Thanks.
Oleg.
