NFS mount Permission denied

Rajendra prasad NVR — Tue, 01 Mar 2011 05:23:49 GMT

I had entered below line in /etc/exportfs
/var/opt/ignite/recovery/archives/ttux -anon=2,access=ttux
and exportfs -av.

When i try to mount from ttux it is giving error Permission denied.

But it work fine if i put/var/opt/ignite/recovery/archives/ttux -anon=2 and re-export it work fine.

My problem is exporting to every one is security breach. How to export to access nfs mount to a single system.

Thanks in advance.

What HP-UX version are you using?
Specify the FQDN instead of just ttux.

Hi,
Did you checked the hosts entry in NFS server.
you need to have the host entry for the client in /etc/hosts file on NFS server, in case if you don't have the DNS configured.

Thanks,
Shan.

On the Ignite server, run "nslookup ".

If the command cannot find the name "ttux", you may have a problem in the reverse mapping (IP -> name) records of your DNS. Ask your DNS administrator to fix that. As a workaround, you can add the name and IP address of ttux to /etc/hosts and try the command again.

Once nslookup can report the name of ttux when queried by IP address, your IP-to-hostname lookup works. You must use the _exact_ name reported by nslookup in your /etc/exports line: if nslookup reports "Name: ttux.company.com", you must specify "access=ttux.company.com", not just "access=ttux".

Hello,

This is peculiar issue with net recovery...
make sure DNS entry is fine and working with forward and revers look up of rserver FQDN , IP. This should resolve the issue.

It is working fine if remove anon=2,access=ttux
in /etc/exports that means to every one nfs share. But i want to know what is correct syntax to nfs share in ignite sever setup.

If i give share to every one it is working which lead to security issue.

Have you specified the FQDN instead of just ttux, as I said above?

>> /var/opt/ignite/recovery/archives/ttux -anon=2,access=ttux

Your syntax is correct. Have you checked the permission of that directory ?

If you feel all fine, then try to change the option. Add following with the existing one.

rw=ttux,root=ttux

Final will be looks like this:

/var/opt/ignite/recovery/archives/ttux -rw=ttux,anon=2,access=ttux,root=ttux

Now try to re-export and try to mount.

this would also be a security leak... IMHO ignite doesn't require this...

Rajendra,

you said that if you export the share to everyone it can be mounted without problems. That should clearly point to a name resolution problem. Post the o/p of:

# nsquery hosts ttux

nsquery is similar to nslookup but it works by using nsswitch.conf which is the same way name resolution works with nfs.
