The fifth and sixth fields on each line are not used
by NFS, thus conventionally each contain the digit zero. For example:
.P
-.SP
-.NF
-.TA 2.5i +0.75i +0.75i +1.0i
+.nf
+.ta 8n +14n +14n +9n +20n
server:path /mountpoint fstype option,option,... 0 0
-.FI
+.fi
.P
The server's hostname and export pathname
are separated by a colon, while
file causes the mount command to negotiate
reasonable defaults for NFS behavior.
.P
-.NF
-.TA 2.5i +0.7i +0.7i +.7i
+.nf
+.ta 8n +16n +6n +6n +30n
server:/export /mnt nfs defaults 0 0

.P
Here is an example from an /etc/fstab file for an NFS version 2 mount over UDP.

+.nf

Try this example to mount using NFS version 4 over TCP
with Kerberos 5 mutual authentication.

This example shows how to mount an NFS server
using a raw IPv6 link-local address.
