I've set up a freeNAS server with an old computer laying around, here is my set up :
I've set up the server as in doc.freenas.org/index.php/Unix_%28NFS%29_Shares]Unix (NFS) Shares - Freenas :

1. A volume named /mnt/data has its permissions set to the nobody user account and the nobody group.

2. A NFS share has been created with the following attributes:

Path: /mnt/Main

Authorized Network: 192.168.178.0/32

MapAll User and MapAll Group are both set to nobody

the All Directories checkbox has been checked

But it is impossible for me to mount it to the existing FreeNAS folder :

MyComputer ~ $ sudo mount -t nfs 192.168.178.31:/mnt/Main /home/Me/FreeNAS

mount: wrong fs type, bad option, bad superblock on 192.168.178.31:/mnt/Main,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount.<type> helper program)
In some cases useful info is found in syslog - try
dmesg | tail or so

I followed the tips from ben.goodacre.name/tech/Error:_mount:_wrong_fs_type,_bad_option,_bad_super block_%28NFS%29]Error: mount: wrong fs type, bad option, bad superblock (NFS) - ben.goodacre.name/tech and here is what my terminal says :

MyComputer ~ $ sudo apt-get install nfs-common
Reading package lists... Done

MyComputer ~ $ rpcinfo -p
The program 'rpcinfo' is currently not installed. You can install it by typing:
sudo apt-get install rpcbind

MyComputer ~ $ sudo apt-get install rpcbind
Reading package lists... Done

Portmap is of course not runing, nfs IS installed and it seems that i cant install the "rpcbind" package... Same with chkconfig.

I am getting kinda crazy here and i am no Linux Guru ... What is wrong ? What should i do ???

PS: I'm runing the brand new version of Linux Mint Cinamon (I think it's n*15)
