How To use SME as an NFS server

This came from a dtech post about to use SME as a NFS server

	Note:
	you have some documentation available for CENTOS6 and CENTOS5

1. Install the smeserver-nfs contrib like this:

yum install smeserver-nfs --enablerepo=smecontribs

2. Then execute the following:

• sme8

config setprop nfs status enabled
config setprop portmap status enabled
config setprop nfslock status enabled

• sme9

config setprop nfs status enabled
config setprop rpcbind status enabled
config setprop nfslock status enabled

3. Edit /etc/exports to add the directories to be shared (this line exports user home directories and ibays):

/home/e-smith/files    *.mydomain(rw,sync,no_wdelay,nohide,no_root_squash)

/home/e-smith/files  – shared directory

192.168.1.0/24           – IP address range of clients
or
*.mydomain               – Domain's client allowed

rw                       – Writable permission to shared folder
sync                     – Synchronize shared directory
no_root_squash           – Enable root privilege
no_all_squash            – Enable user’s authority

if you want to see all your exports

showmount -e

	Warning:
	Make sure to leave a blank line at the end of the file.

4. Then, the following, which will reboot the server:

signal-event post-upgrade; signal-event reboot

Couple of notes whilst installing on SME8.....

DB options as follows - status disabled by default :

nfs=service
   TCPPorts=2049,4002,4003
   UDPPorts=2049,4002,4003
   access=private
   mountdPort=4002
   rquotadPort=4003
   status=disabled

nfslock=service
   TCPPorts=4000,4001,4004
   UDPPorts=4000,4001,4004
   access=private
   lockdPort=4001
   statdOutgoingPort=4004
   statdPort=4000
   status=disabled

portmap=service
   TCPPort=111
   UDPPort=111
   access=private
   status=disabled

After installation & reboot you should be able to update with

signal-event remoteaccess-update

However, I don't think this starts/restarts portmap, hence the reboot on install which should not really be necessary.

see exported folders

You can have a look on all exported folders and see for which ip/network they are allowed.

# showmount -e
Export list for hpcompact:
/home/e-smith/files/ibays/toto/files        192.168.15.0/24,192.168.12.0/24
/home/e-smith/files/ibays/laurence/files    192.168.12.100,192.168.12.125
/home/e-smith/files/ibays/dolibarr/files    192.168.15.0/24,192.168.12.0/24
/home/e-smith/files/ibays/admin_25465/files 192.168.15.0/24,192.168.12.0/24

find connected clients

netstat -an | grep nfs.server.ip:port

• for example

# netstat -an | grep 192.168.12.125:2049
tcp        0      0 192.168.12.125:2049         192.168.12.25:850           ESTABLISHED 

client side

• nfs-comon

install nfs-common (it depends of your distribution)

• mount the network share

mkdir /mnt/partage
mount -t nfs 192.168.xx.xxx:/home/e-smith/files /mnt/partage
ll /mnt/partage

ToDos

Probably better to make a custom template for /etc/exports

Would be better if there was a web panel to enable/disable nfs per ibay
