nfs dont want to work

stefane321 · 06-08-2007, 04:56 PM

My server is a Fedora core 6 and my client a suse 10.2

On the server I edited /etc/exports like this:

Quote:

/var/www/html 192.168.0.138(rw,sync,all_squash,anonuid=500,anongid=500)

After I did :

exportfs-a
service nfs restart
service network restart

On the client I did:

Quote:

mount -t nfs 192.168.0.100:/var/www/html /home/stephane/web2

But I always got these error:

Quote:

mount server reported tpc not available,falling back to udp.
mount: RPC: Program not registred

I searched a lot on google so I configured :

hosts.allow:

Quote:

portmap:192.168.0.138
lockd:192.168.0.138
mountd:192.168.0.138
rquotad:192.168.0.138
statd:192.168.0.138

hosts.deny:

Quote:

portmap:ALL
lockd:ALL
mountd:ALL
rquotad:ALL
statd:ALL

I opened these port:

Quote:

111:tcp, 111:udp, 2049:tcp, 2049:udp, 4001:tcp, 4001:udp, 4002:tcp, 4002:udp, 4003:tcp, 4003:udp, 4004:tcp, 4004:udp

Like explained in this post:

http://www.linuxquestions.org/questi...d.php?t=294069

I did :

Quote:

1. Create the file "/etc/sysconfig/nfs" and add the following contents:

STATD_PORT=4001
LOCKD_TCPPORT=4002
LOCKD_UDPPORT=4002
MOUNTD_PORT=4003

2. Append the following to the file "/etc/services":

rquotad 4004/tcp # rpc.rquotad tcp port
rquotad 4004/udp # rpc.rquotad udp port

3. Restart the nfs services:

/etc/init.d/nfs restart
/etc/init.d/nfslock restart

If I do rpcinfo -p I got:

Quote:

100000 2 tcp 111 portmapper

portmap is essencial to nfs to work.
Is portmap running ?

stefane321 · 06-08-2007, 07:23 PM

Yes, Portmap is runnig

marozsas · 06-09-2007, 10:31 AM

like in the thread you mentioned, if you disable the firewall, did you got the nfs mount to work ?
And just for testing, try to disable SELinux too.
(SELINUX=disabled in /etc/selinux/config)

stefane321 · 06-09-2007, 10:57 PM

Yes I tried it.

I disabled the firewall and its dont work.

Thanks!

Any other idea?

What do you get if you do:

rpcinfo -p <server IP>

from the client machine?

stefane321 · 06-10-2007, 07:32 AM

If I do on the :

Quote:

rpcinfo -p 192.168.0.100

I got:

Quote:

No remote programs registered.

Hey, I could be wrong, but the service nfs is the client. On the server the right service is nfs-server or something like that. Check. I don't have a working nfs server here at home, but I believe you didn't start the right service on server.

Just check the right name of nfs server. Take a look at /etc/init.d for scripts that have nfs on name. I just remembered another related one: nfs-lock, which is need in the server side.

searching a little bit on my home machine (a Fedora 7) looks like there is no a standalone nfs server. Instead, nfs server is built on kernel, and there is no a /etc/init.d/nfs-server script or whatever on this machine.

I don't know if it is the same in FC6.

At the work, my nfs server is running on an opensuse 10.2, so it wont help anyway.

..and it is strange rpcinfo tells there is no programs registerd on server. Are you sure portmap is running on server ?

POST EDIT: Never mind, I checked in F7 and the nfs server is /etc/init.d/nfs. Probably is the same in FC6.
But now, who is the nfs client ??? It is kernel based ?

stefane321 · 06-11-2007, 01:56 PM

If I do on the server :

ps -aux

I got 8 nfsd process is it normal?

Sorry for everybody,

My bug was stupid !

I did a mistake in the hosts.allow file I entered a wrong ip address.
