NFS mount

SERVER (192.168.1.182)

Make sure nfs is running on the server

$ /etc/init.d/nfs restart

At the server the contents of /etc/exports for
allowing 2 computers (192.168.1.171 and 192.168.1.71)
to access the home directory of this server. Note that
read write (rw) access is allowed.

$ cat /etc/exports
/home   192.168.1.171(rw)
/home   192.168.1.71(rw)

Or, if you have a lot of clients on 192.168.1.* then consider
the following:

/home 192.168.1.0/255.255.252.0(rw)

Next, still at the server, run the exportfs command

$ exportfs -rv

IPTABLES (lokkit). If you're using fedora with default lokkit firewall
then you can put the following under "Other ports".

Other ports nfs:tcp nfs:udp


If the above does not work or you are not using lokkit
IPTABLES (values in /etc/sysconfig/iptables on SERVER )

CLIENT1 (192.168.1.171)

$ mkdir -p /home2

$ cat /etc/fstab
192.168.1.182:/home          /home2     nfs     rw 0 0

$ mount -a -t nfs

Or to do a one time mounting by hand

$ mount -t nfs 192.168.1.182:/home  /home2

Now /home2 on the client will be /home on the server

MONITOR NFS:

To monitor the client:

$ nfsstat -c

Also note you can "cat /proc/net/rpc/nfs" as well.

To monitor the server (note the -s instead of the -c).

$ nfsstat -s

Also note you can "cat /proc/net/rpc/nfsd" as well.


The following "cat" command is done on the NFS server, and shows which
clients are mounting. This does not go with examples above. By the way,
"root_squash" is the default, and means that root access on the clients is
denied. So, how does the client root get access to these filesystems? You have
to "su - <someuser>".

$ cat /proc/fs/nfs/exports
# Version 1.1
# Path Client(Flags) # IPs
/home   192.168.1.102(rw,root_squash,sync,wdelay)
/home   squeezel.squeezel.com(rw,root_squash,sync,wdelay)
/home   192.168.1.106(rw,root_squash,sync,wdelay)
/home   livingroom.squeezel.com(rw,root_squash,sync,wdelay)
/home   10.8.0.1(rw,root_squash,sync,wdelay)
/home   closet.squeezel.com(rw,root_squash,sync,wdelay)
