I want to make an NFS share between my 2 PC's
One is slackware 32 current as server/client
The other is ubuntu 10.04 as client/server

Slackware can see the shared folder of ubuntu
But I can't mount the shared folder of slackware in ubuntu.
The error message is :
mount-nfs : an incorrect mount option was specified

Also when I run a 'showmount -e IP_Server' in the ubuntu PC
I have this message :
'clnt_create : RPC : Program not registred'.

On 10.0.0.1, you need to put:

/whatever/directory 10.0.0.2(rw,no_root_squash)

in /etc/exports - this says 10.0.0.2 is allowed to mount /whatever/directory as an nfs filesystem with full rights. Then, on 10.0.0.2, you can add a line in /etc/fstab:

10.0.0.1:/whatever/directory /mnt/mountfolder nfs rw,suid,soft 0 0

or simply issue a mount command at the command line:

mount -t nfs //10.0.0.1/whatever/diretory /mnt/mountfolder

are you sure the nfs server is running? what about portmap? you should get portmap up and running before nfs-server. what says rpcinfo?

J'ai fait ça mais toujours pas de montage possible sur poste client.

voilà pour le rpcinfo sur serveur :

You got a

127.0.0.1 localhost

in your /etc/hosts ?

Yes I've got one
127.0.0.1 localhost

in my /etc/hosts

I'm going to read all this.
NFS and Network in general are part of my favorites themes.

But, I'm wondering if the problem is not coming from a bug in my Client PC, as far as I can't even see my slackware server in the neighbourhood of my client PC when I can see other servers as for exemple my NAS (Synology).

Hi,

Not knowing your '/etc/exports' file nor any of the 'hosts' files it is hard to aid you.
All the necessary services are running?

Hello,

Surely the services are running!!

I can see all remote servers/client (NAS,and my other PC (ubuntu)) in my slackware PC.
But I can't see the slackware PC in my other PC (ubuntu).

Here are the exports and fstab files in both PC.

I want to share a folder (ASRock) of my slackware PC in my other PC (ubuntu)
So here is the /etc/exports file in the slackware PC
/home/njb/ASRock/ 192.168.1.29(rw,all_squash,anonuid=5000,anongid=5000,sync)

I want to mount this folder (ASRock) of my slackware PC in my other PC (ubuntu)
So here is the /etc/fstab file in my other PC (ubuntu)
192.168.1.30:/home/njb/ASRock /media/ASRock nfs suid,dev,exec,auto,user,async,rsize=8192,wsize=8192,soft,timeo=14,intr 0 0

I always get an error message in the other PC (ubuntu)
'incorrect mount option was specified'
And what seems strange is that I can make other NFS mounts in this other PC (ubuntu)

Mount it from the command line. Give less and less options until you have no such error. Then you know which option is invalid.
