Hi Everyone,
I've export a directory from the AIX NFS server. It don't have any problem being NFS mounted by other AIX system. While I tried to use one linux doing the same NFS mount, it returned the " permittion denied" error.

Is there anything special I should do on this linux client before I do the "NFS mount" ?


Appreciate for any suggestion
Regards
Denny

Can someone help me ? Is there any NFS log I can check ?

nfso -p -o nfs_use_reserved_ports=1

by the way, look at your network installation.
"Permission denied" usually means "I don't know this guy".
1) go to the AIX system, and type "ping -c 3 my_linux_client".
2) On the AIX server system, "cat /etc/exports" in order to verify that your fileystem is correctly exported.
3) usually, on Linux systems, "mount aix_server:/shared_filesystem /mnt" works without problem.

Is the nfso command mentioned above not only applicable to an AIX NFS client?

I have the same problems, by the way.

The exports on the AIX server are listed without any options, only -root=myclient
where myclient is an antry in the hosts file with the proper IP address.

I use RedHat ES3, trying to connect to an NFS server on an AIX 4.3 cluster.

This is the dump of nfso -a:

portcheck= 0
udpchecksum= 1
nfs_socketsize= 60000
nfs_tcp_socketsize= 60000
nfs_setattr_error= 0

nfs_v2_pdts= 1
nfs_v3_pdts= 1
nfs_v2_vm_bufs= 1000
nfs_v3_vm_bufs= 1000


I tried mostly with the client defaults, and also with option "udp"

The problem is that I cannot use "trial and error" since it seems that in some occasions the portmapper dies on the AIX server.

I have the same problem here and I found out why I get this error:
on my server my uid is 500 and on my client 501 so they dont match which cause the access denied.

well, I'm a bit confused what your exact issue is, but here is how I mount on my Redhat server an AIX mount:

10.28.1.61:/u37/somedir /mnt/somedir nfs rsize=8192,wsize=8192,intr,posix 0 0

and on AIX, that export looks like:
/u33/cold_backups -root=hqs6000aortal2,access=hqs6000aortal2

portal2 being the Redhat box. Key is making SURE hostname is in /etc/hosts on the AIX box and that your UID/GID matches up between the two boxes. I hope this makes sense.

Hi,

I configured on NFS at Linux site (client of AIX) as follow:

Directory: /mnt/testdatalinuxclient
Host: <ip of aix server>
Permision is Read/Write and chmod -R 777 /mnt/testdatalinuxclient

At aix server, I use command:
mount -o proto=udp <ip of Linux client>:/mnt/testdatalinuxclient /mnt/testdataaixserver

Mount failed. Error message:

mount: 1831-008 giving up on:
<ip of linuxclient>:/mnt/testdatalinuxclient
vmount: Operation not permitted.

Please help me fix this. Thanks so much.

It works well. Thanks Mark Taylor.
