I don't know of any other protocol which uses the OSI-stack with the
inactive-
subset-CLNP flavour. "Inactive subset" means in fact "no routing, just
one wire".
So it is not likely to have any collision between different future
dissectors.
(Btw.: which other protocols use the OSI-stack?)
But you are right, the scheme to return FALSE if a higher
level-dissector
can't handle the packet is better. This gives more flexibility.
Because I'm living behind a firewall, which blocks CVS, I have wait for
the
next release and your enhancements to the code - and of course the new
HOWTO.
Afterwards I will start the next round of development for S7.
Beside of the H1-protocol there is another protocol of interest for us:
The TCP/IP-based protocol used by Allen-Bradley for their
PLC's. - See http://freshmeat.net/appindex/1999/11/07/941993013.html
for Ron Gage's linux-based communication library.
It is basically the AB DF1 protocol over TCP/IP with Port 2222.
Thanks for your efforts
