NFS or Networked File System is a protocol used to share filesystems over a network. IRIX 6.5 includes support for NFSv2 and NFSv3.

== Hosting NFS ==
'''NFSv2 and NFSv3 have known security problems and exploits. It's highly advised to use a proper firewall and configuration.'''

NFS can be hosted from IRIX, BSD, Solaris/illumos, Linux or even some versions of macOS and still retain compatibility to IRIX. This page documents related issues with NFSv3/2 and the various quirks to get it working on each host OS.

=== Recommended Hosts ===
The easiest hosts to get working with IRIX are, in no particular order:

* illumos/Solaris
* FreeBSD
* NetBSD
* IRIX 6.5.22 or higher
* Windows 10 Pro or Enterprise

=== Not Recommended ===
These hosts have a number of server and implementation issues with NFSv3, if there are tricks unheard of yet to getting them working please feel free to add tricks below:

* Linux: rpcbind in Linux is buggy, and the nfsd module usually gets interfered with by SELinux, systemd and other modern Linuxisms.
* macOS: The most recent versions do not appear to have proper NFSv3 support for hosting, though NFSv3 connections do appear to work.

== Guides ==

==== FreeBSD ====
FreeBSD supports NFSv3 for IRIX easily.

'''Enabling Services'''

The following lines must be added to the /etc/rc.conf file:
rpcbind_enable="YES"

nfs_server_enable="YES"

mountd_enable="YES"

mountd_flags="-r -p 735"
Now start the services:

<code># service rpcbind start; service nfsd start; service mountd reload</code>

'''Exporting'''

On ZFS, do not use /etc/exports. Instead, use:

<code>zfs sharenfs="-network 10.0.0.0 -mask 255.255.255.0" tank/protected</code>

This will share the tank/protected dataset on LAN addresses 10.0.0.0/24

Further examples will include PF firewall rules to ensure spoofed/hostile traffic cannot compromise NFS.

==== Linux (Ubuntu) ====
Thanks to Larbob/lbdm for this guide.

'''Preparation'''

Install the NFS subsystem:

<code>sudo apt install nfs-kernel-server</code>

Make an NFS share directory:

<code>sudo mkdir -p /srv/nfs</code>

Set up /etc/exports with something like this:

<code>/srv/nfs 192.168.0.0/24(rw,sync,no_subtree_check,no_root_squash)</code>

Edit /etc/default/nfs-kernel-server's RPCMOUNTDOPTS section to add --no-nfs-version 4

'''Finishing Touches'''
sudo exportfs -ra

sudo systemctl restart nfs-config

sudo systemctl restart nfs-kernel-server
This will provide a setup to allow anyone with uid 0 to write as root. Please be careful if deciding this
