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
```
