I had a similar problem between two FreeBSD machines, except that there was no mismatch: both client and server were UDP. And it hung all over the place. It seems that two FreeBSD machines alone on a 100MB network had timing problems in the UDP NFS code. Finally figured out that it wasn't using TCP and switching to that fixed the hangs. The real problem is that reading the documentation cover to cover, it is easy to assume that the default must be TCP, because they say don't use UDP unless there is a gun to your head, blah blah, so there is no need to specifically specify that [using the available args]. I don't think the defaults are explicitly specified in the man pages and HOWTOs and what not. Perhaps in the NFS spec, but.... a Graeme Brown wrote: > > Dear Freddijanto > > Thanks for your reply.
