NFS Shares initally worked, after reboot don't connect anymore.

[ScottyK]

Recently I followed a tutorial I found to allow my desktop and Notebook to connect and share files via NFS.

After following the tutorial, everything worked, and I was able to share files!

Since then both computers have rebooted, and now neither will connect.

Looking at the drives in Dolphin, I can see that the share on the other computer is disconnected. When I go to click on it, I get the following error -

An error occurred while accessing '/home/scott on 192.168.1.68', the system responded: mount: only root can mount 192.168.1.68:/home/scott on /home/scott/Notebook

First I verified that the notebook was still at 192.168.1.68 and it is.

Next I opened dolphin in root to see of that worked. When I click on the drive while in Dolphin (root) I get this error message..

An error occurred while accessing '/home/scott on 192.168.1.68', the system responded: mount.nfs: access denied by server while mounting 192.168.1.68:/home/scott

The connectivity is good, for I can still connect to both drives via SAMBA.

Both computers are giving the same errors.

The tutorial I followed is located here: http://mostlylinux.wordpress.com/net.../#introduction

check your hosts allow/deny files and exports ,,,,,,,and lets see them and the fstab line

Desktop -

Allow -

rpcbind mountd nfsd statd lockd rquotad : 127.0.0.1 192.168.1.68

Deny -

rpcbind mountd nfsd statd lockd rquotad : ALL

fstab

192.168.1.68:/home/scott /home/scott/Notebook nfs rw,hard,intr,noexec 0 0

Notebook is the same, with the exception of 192.168.1.99 instead of 192.168.1.68

Whats the output of:

sudo showmount -e <IP_OF_OTHER_COMPUTER>

[oshunluvr]

you're probably running ito the nfsV4 vs. nfsV3 issues. exports are different and that tutorial is getting long in the tooth.

Notebook -

sudo showmount -e

clnt_create: RPC: Port mapper failure - Authentication error

Desktop -

sudo showmount -e

clnt_create: RPC: Port mapper failure - Authentication error

You have to provide an IP address to 'another' PC for the command to work.

[ScottyK]

Placing the IP address at the end of the command generates the same error.

It's been a long day at work, I'm probably missing the obvious.

On the laptop that I want to be able to access the other laptop, this is the fstab entry:

# shared
192.168.xx.xxx:/home/paul /home/paul/shared nfs rw,hard,intr,noexec,users 0 0
(my actual IP masked for this post)

I followed the same tutorial you cited, and it works perfectly here.

If the mounts aren't showing, you can't mount them because they aren't exported. What are the contents of /etc/exports

[ScottyK]

/home/scott 192.168.1.99(rw,sync,no_subtree_check)

[oshunluvr]

Hmmm, run this on both ends and try again:

sudo exportfs -ra

sudo exportfs -ra

Seems to have no effect.

However the Samba share in /home/public suddenly showed up, and I can now transfer files using Samba

Maybe you could try autofs with nfs v4. I have it working perfectly on Kubuntu 13.10 and 12.04 over Nas4Free and FreeNas nfs shares.

auto.master only needs :
/net -hosts

Then restart autofs : service autofs restart

Then simply : ls /net/<nfs-server-name>

The share names won't appear until you try to use them.

It got issues trying to use nfs v3 as I did before with Kubuntu 8.04 and 10.04.

Hope this helps...
