Linux NFSv4 Howto

NFS is commonly used to share files on Linux. NFSv4 is the latest protocol and circumvents firewall related complications experienced with NFSv3 by requiring only ONE fixed tcp port open on the server side. It is surprisingly easy to set up:

Server side:

1. Edit /etc/exports and add directories to be exported (fsid=0 is a mandatory option for nfs4) and authorized clients (check the exports manpage)
   


2. Open up tcp port 2049 on the firewall
   


3. # /etc/init.d/nfs restart
   


4. # chkconfig --level 345 nfs on
   

Client side:

1. # mount -t nfs4 -o rw,intr,hard server:/ /mount/point
   

It is not necessary to specify the exact path on the "server:/" with NFSv4.
