====== NFS Network File System Howto ======
===== General Steps =====
  - Install nfs packages
  - Alter /etc/exports
  - Restart nfs server
  - Mount on client

===== Server Commands =====
  * Install nfs packages for Ubuntu/debian
    * <code>
sudo apt-get install nfs-kernel-server nfs-common portmap
</code>
    * Following install statements may be important:
      * <code>
Creating config file /etc/idmapd.conf with new version
Creating config file /etc/default/nfs-common with new version
Adding system user `statd' (UID 112) ...
Adding new user `statd' (UID 112) with group `nogroup' ...
...
Creating config file /etc/exports with new version
Creating config file /etc/default/nfs-kernel-server with new version
</code>
  * Add something like the following to /etc/exports . See [[http://gentoo-wiki.com/HOWTO_Share_Directories_via_NFS#Modify_EXPORTS|here]] for more details
    * rw - read write access
    * async - double checks file writes, faster, riskier (can corrupt easier)
    * no_subtree_check - do not invoke subtree algorithm which verifies that a file that is requested from the client is in the appropriate part of the volume.
    * <code>
# raid5 lms (linux media server) share
/media/documents   192.168.1.0/255.255.255.0(rw,async,no_subtree_check)
</code>
  * Restart the nfs server
    * <code>sudo /etc/init.d/nfs-kernel-server restart</code>
  * Update nfs file share lists
    * <code>sudo exportfs -a</code>
  * Version and other info of running nfs's
    * <code>nfsstat</code>



===== Mac OS X =====
==== Finder ====
  * Ctrl+K
  * nfs://server.name/path/of/share
==== Command Prompt ====
  * <code>mount -o -P lms:/media/documents /Volumes/lms</code>
==== Directory Utility ====
A built-in utility to OS X after Leopard that can keep track of mounts via a nice GUI.

  * See http://zawaarudo.blogspot.com/2008/06/directory-utility-and-remote-nfs-mounts.html
  * **<del>Automount</del>** Deprecated now that Directory Utility above does the same... easier
==== Bonjour ====
  * See See http://ubuntuforums.org/showthread.php?p=4387032#post4387032 for some details


===== Linux =====
==== Command Prompt ====
  * <code>mount master.foo.com:/home /mnt/home</code>
==== /etc/fstab file ====
  * <code>
# device       mountpoint     fs-type     options      dump fsckorder
...
master.foo.com:/home  /mnt    nfs          rw            0    0
...
</code>


===== Cavaets =====
  * Syntax errors in /etc/exports
  * options not correct in exports file
  * uid / gid not matching on client and server
  * little windows support
