Thanks for the help on this. I compiled the latest cvs code this afternoon and was able to load the captures and immediately noticed a large improvement. Unfortunately, I think the information I really need is in the fragmented requests and I hope the infrastructure will be able to handle the fragments in the future. They are IPX/SPX packets and I am not sure they use the same start, offset, end sequence that IP does.

We are still having the login problems and I will be getting more traces tomorrow. If you want them I will send them to the list.

Thanks again,
Pete 

Your trace has fragmented NDS requests in it (NCP code 0x6802).
It will be interesting to see what Ethereal can do with
these fragments in the future, i.e., will the infrastructure
we put in place be able to unfragment the NDS requests????

The current fragment reassembly code in "reassemble.c" should be able to
handle any form of fragment reassembly that's similar to IPv4's; both
IPv6 and CLNP fragmentation are similar, so it currently handles IPv4,
IPv6, and CLNP.

If NDS's fragmentation is similar (meaning each fragment has:

a starting offset within the fragmented packet;

a length;

a "this is the last fragment" Boolean)

it should be abel to use it.
