Hi, After I implemented sysctl that can specify to suppress feature negotiation and enabled it, my NetBSD implementation can communicate with Linux! :)
I also fixed some bugs, so I think you can also play FreeBSD5 DCCP implementation now. If you could play with my implementations and could give me any feedback, I would be grateful very much. I'm going to take a look at time stamp option processing in linux to see if I can find anything. Thanks, -- Yoshifumi Nishida [EMAIL PROTECTED] Sony Computer Science Laboratories, Inc.
