Linux: how to check the remote NFS server version

• The following command can be used to check the version of the remote NFS server:

  rpcinfo -s remote-server.yourdomain.org | grep nfs

  it will return the result like below:

  100003  2,3       udp,tcp                          nfs         unknown

  the second column, 2,3, are the versions of the nfs servers running on the remote host.
• or if your rpcinfo implementation does not support -s option, you can

  rpcinfo -p remote-server.yourdomain.org | grep nfs

  it will return the result like below:

  100003    3   tcp   2049  nfs
  100003    2   tcp   2049  nfs
  100003    3   udp   2049  nfs
  100003    2   udp   2049  nfs

  the second column shows the version of the nfs server.
• To check the nfs server running on localhost, you can

  rpcinfo -s localhost

  or

  rpcinfo -p localhost

  or

  sudo nfsstat
