The clientname and servername will limit things to just those two machines. And the -x will capture most of the pay load. You can then do snoop -i /root/os2jg.snoop to look at output. And you can also use -V and -v for verbosity. Wireshark also understands snoop. > > This OpenSolaris/x86 system successfully mounts a Linux NFSv4 server, > so I know that networking and NFSv4 _do_ work on the OpenSolaris client. > > What are the best methods to debug the mount process? > > If it matters, my NFSv4 server does not register itself with rpcbind / > mount / portmap / etc. services.

You could do a showmount -e against the server and see if that hangs as well. A more complete snoop trace could help.
