NFS Issue?

your_shadow03 · 05-11-2009, 06:32 AM

I have two RHEL Machines rh1 and rh2.I tried to creat rh1 as NFS Server and edited /etc/exports as:

Code:

/home/fdmin/arch                          *(rw,sync,no_root_squash)

And exports -a worked without any error.
Restarted nfs
Showmount -e localhost showing good.

I tried running this on rh2
It says:

Code:

# mount -t nfs rh1:/home/fdmin/arch /tmp/res
mount: rhn1:/home/fdmin/arc/ failed, reason given by server: Permission denied
#

Showmount -e rh1 worked and shows fine on rh2 but rh2 is not able to mount rh1.

Also, If I try making rh2 as server and rh1 as client it works fine.
Why does the first setup doesnt work?

what do your logs say?

your_shadow03 · 05-11-2009, 01:01 PM

Which logs?are you talking about /var/log/messages?
It doesnt show any error?

On neither machine? How odd.

Cheers,
Tink

Is the firewall/selinux enabled on either host? Are you using tcp_wrppers? Is there any other firewall in the picture (cisco or any other hardware firewall)?

I'd take a look at your permissions for the exported directory. Try bringing it all the way forward (777) then scaling back.

Its 777 what chmod says.
se-Linux is disabled too.

What about the firewall? Any firewalls involved?

Code:

#service iptables stop

shows no output

chrism01 · 05-12-2009, 11:26 PM

That's normal for *nix. If you issue a basic cmd and it works, there's normally no output.
what we need is

iptables -L

on both systems when iptables is up. Mind you if it doesn't work after you've stopped iptables on BOTH systems, then its not an iptables issue.
Have checked tcp_wrappers (hosts.allow, hosts.deny) in /etc ?

your_shadow03 · 05-13-2009, 03:09 AM

/etc/hosts.allow and /etc/hosts.deny seems to be completely hashed.

your_shadow03 · 05-13-2009, 03:11 AM

[root@131e ~]# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination
[root@131e ~]#

Question...

Are you using /etc/hosts.allow /etc/hosts.deny?

-C

chrism01 · 05-13-2009, 07:54 PM

Use
service iptables stop
on BOTH systems and try again. If it doesn't work, show us hosts.allow, hosts.deny from BOTH systems. Saying they are 'hashed' is meaningless!
(They are plain text files)
