Nfs Permission Pbm.

[Sofiane LARDJANE]

Hi all,

I want to export a directory from hostA server :
on hostA
# cat /etc/exports
/test access=hostB,ro

When trying to mount on hostB permission denied is displayed. however on hostA when I put in /etc/exports this line :
/test ro
then on hostB, I can mount it without problems !

Can u advise please ?

Sofiane.

From hostB, if you do showmount -e hostA, what does it show? Does it show that share is allowed to be mounted from hostB?

[Michael Steele_2]

/test -access=hostB,ro,root=hostB

esportfs -av (* re-export *)
exportfs -v (* list exported *0
exportfs -uav (* unexport *)

verify you DNS with nslookup and /etc/hosts. Use fully Qualified domain name in /etc/hosts.

If you substitute the IP address for the host name then you're not resolving the host name.

check nsswitch.conf for correct hostname resolution.

check your nfs

rpcinfo -p ( master/client ) (* verify rpcbind, status, nfs, mountd, nlockmgr, llockmgr *)

You show;
/test access=hostB,ro

Is that a typo? Should be;
/test -access=hostB,ro

access is an option switch, but you show no - in front of it.

thx for your help but still not working.

I check all the configuration files and all daemons and it's ok. I also change the hostname by it's Ip @ and still not working !

[Glen R. Bartlett]

As others have eluded to, this sounds like a name / resolution issue.

With no hostname specified in the exports file, its a blanket allowance for any host to mount it.

Not to be insulting, but I assume hostA and hostB can ping each other fine using those names?

There are no alias issues in /etc/hosts?

Does /etc/xtab show /test as being exported properly i.e. /etc/xtab resolves symbolic link? (if /test is one).

[Sofiane LARDJANE]

hostA and hostB ping together so I don't think it's host/name resolution issue !

thx,

i had the same problem.
try to just write /test on /etc/exports

[Sofiane LARDJANE]

When I just write /test on /etc/exports it can be mounted , my problem is the option -access ?

[Glen R. Bartlett]

Try changing the line in /etc/exports to:

/test -ro=hostB

And execute exportfs -a to refresh.

Hope this helps,
Glen

exportfs error: unknown option: ro=hostB

What version of HP-UX are you running?

/test -access=hostB,ro

Works fine for me on 11i v1
Are the following processes running?
biod
nfsd
rpcbind
rpcd
lockd
statd
mountd

What command are you using to try to mount the remote directory?
