Failed to mount the root directory via nfs
 

I am a newbie at Linux and I am trying to connect my thin client to my Linux server, this is the error I get at the workstation computer, I am lost with this error, I have checked nfs services and it is running, but I do Not know how to fix this error so my thin client can connect to my server, below is the error I get from my workstation. Can some please help as I need to get this to work for my boss?

This is the error i get


Running dhcp on port 67

Mounting root filesystem:192.168.1.4/opt/ltsp/i386 from:
Mount: Unknown host
Mount: nfsmount failed: Connection refused nfs warning: mount version newer than kernel
RPC: send msg returned error 22
nfs:rpc call returned error 22
nfs-get-root: getattr error=22
nfs_read-super= get root inode failed
Mount: mpounting-192.168.1.4/opt/ltsp/i386 on/mnt failed: Invalid argument

Error! Failed to mount the root directory via NFS


Possible reasons include:

1) NFS services may not be running on the server

2) Workstation IP does not map to a hostname, either in /etc/hosts or in DNS.

3) Wrong address for NFS server in the dhcp config file

4) Wrong pathname for root directory in the DHCP config file

In my opinion, correct syntax should be :
192.168.1.4:/opt/ltsp/i386

(note the ':' between ip and file path)
Could you post your dhcp conf ?

Dhcpd details
 

Thank you for your reply, as i said i am brand new in Linux less then one week old learing Linux, so be easy on me. As mentinoned before the thin client is supose to connect and log in to the Linux server, but i ran in to the problem mentioned in my last post. Here are the dhcpd details. Soory that it is so lenghty. By the way iam using a Thin client mangement system to help administer the thin clients once i log in.

Any ways here is my dhcpd information
