nfsv4 is slightly more secure than nfsv3 if you do not use kerberos
and much more secure if you do.
I have just read
and I have three additions to the procedure, should you choose nfsv4.
1. The value of
must be the same on your server and your client(s)
to your server export options
3. To mount the same nfs export, /path/to/export
for nfsv3, do on nfsclient
mount -o <nfsvers=3,options> nfsserver:/path/to/export /path/to/mount
for nfsv4, do on nfsclient
mount -t nfs4 -o <options> nfsserver:/ /path/to/mount
