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

  1. 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.

  2. In comp.os.linux.networking :
    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

    Can you provide an example?

  4. 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).

  5. 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

    sid:/ on /mnt/sid type nfs

    spinner ~ #
