How do I determine from a Linux client whether an NFS mount is over UDP or TCP?

On Solaris its nfsstat -m, but I can't find a similar way to do so in
Linux, other than using ethereal. Which I don't want my users to do..

Any help is appreciated.

Thanks!

You can see this from the output of 'mount', if 'tcp' isn't
displayed you are using 'udp' which is the default.

I don't see "tcp" on a mount between two SuSE 9.3 systems. I thought TCP
was supposed to be default now. Also, ethereal shows TCP is being used for
NFS.

Can you provide an example?

From taking a closer look, a few distro seem to have just changed
the default protocol for nfs. So you can't be sure anymore thx to
those punks. But looking at 'cat /proc/mounts' seems to always
display the protocol used no matter which one is used unlike
'mount' which doesn't always show the default (sadly).

Mount works for me...


spinner ~ # mount

nfsd on /proc/fs/nfs type nfsd (rw)

rpc_pipefs on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)

mutley:/ on /mnt/mroot type nfs
(rw,noatime,rsize=65536,wsize=65536,retry=2,hard,i ntr,addr=192.168.0.1,tcp)

sid:/ on /mnt/sid type nfs
(rw,noatime,rsize=65536,wsize=65536,retry=2,hard,i ntr,addr=192.168.0.11,tcp)
