How to set an NFS network?

Question

I want to merge information found here and there in order to record in one answer all steps to set my NFS network between my two Ubuntu PCs

This is useful time to time, for example when switching to a new Ubuntu version, I need to reset :

• NFS
• Autofs
• UFW

Answer 1

Lets say that «boris» is my logon such as /home/boris is my home folder.

1. set the «server» computer:

• install nfs-kernel-server and nfs-common

  $ sudo apt-get install nfs-kernel-server
  $ sudo apt-get install nfs-common
  

• in /etc/exports, define the folder to be shared by adding this:

  /home/boris   192.168.1.0/24(rw,sync,all_squash,anonuid=1001,anongid=1001,subtree_check)
  

  with:
  /home/boris is the folder to be shared
  rw for read and write access of the client
  sync ??
  all_squash ??
  192.168.1.0/24 is a range of client computer IP address of your local network
  1001 is the user and group ID. To find it $ id boris
  

• manage hosts, 1st allow nobody in /etc/hosts.deny add
  

  portmap:ALL
  nfsd:ALL
  mountd:ALL
  

  Then allow your client computer in /etc/hosts.allow add

  portmap:192.168.1.0/24
  lockd:192.168.1.0/24
  nfsd:192.168.1.0/24
  mountd:192.168.1.0/24
  rquotad:192.168.1.0/24
  statd:192.168.1.0/24
  

  with 192.168.1.0/24 is a range of client computer IP address of your local network
  

• set the firewall UFW

  $ sudo ufw enable
  $ sudo ufw default deny incoming
  $ sudo ufw default deny outgoing
  $ sudo ufw allow from 192.168.1.0/24
  $ sudo ufw allow out from 192.168.1.0/24
  

  with 192.168.1.0/24 is a range of client computer IP address of your local network
  

• start the server

  $ sudo /etc/init.d/nfs-kernel-server start
  

  or after a modification of /etc/exports

  $ sudo /etc/init.d/nfs-kernel-server restart
  

2. set the «client» computer:

• install nfs-common and autofs

  $ sudo apt-get install nfs-common
  $ sudo apt-get install autofs
  

• create the folder used to mount the connection with the server

  $ sudo mkdir /media/shareFolder
  

• set autofs to automatically mount this folder,
  in /etc/auto.master add this line:

  /media/shareFolder /etc/auto.nfs --ghost, --timeout=60
  

  in /etc/auto.nfs add this line

  boris  -fstype=nfs,rw,intr,uid=1001,guid=1001   192.168.1.1:/home/boris
  

  with:
  192.168.1.1 is the address of server computer
  /home/boris is the folder shared on server computer.
  1001 is the user and group ID. To find it $ id boris
rw for read and write access

• set the firewall UFW

  $ sudo ufw enable
  $ sudo ufw default deny incoming
  $ sudo ufw default deny outgoing
  $ sudo ufw allow to 192.168.1.1
  $ sudo ufw allow out to 192.168.1.1
  

  with 192.168.1.1 is the address of the server computer
  

• and reboot your client computer.
