NFS and "Permission denied" error

Hello everyone,

I'm trying to set up an NFS server, with MDK 10.1 and nfs-utils-1.0.7,
but from whichever machine I try to mount the exported directory, even
from the server itself, I always get the "Permission denied" error.

My /etc/exports file contains the following:

/tftpboot *(rw,sync,no_root_squash)

The /tftpboot directory is readable and listable by everyone.

The files /etc/hosts.allow and /etc/hosts.deny are both empty (the
network is behind a firewall, I have no need for special protections).

The "showmount -e" command shows that /tftpboot is correctly exported.

Just to be sure, I've even run "exportfs -ra" (but that's something the
script in /etc/init.d should have taken care of already), however I
noticed that instead of updating /var/lib/nfs/xtab (which is left
empty), exportfs updates /var/lib/nfs/etab. I don't know whether this
may be a problem - even if update the xtab file by hand, I get no
positive results.

I really don't know where else to look... has anyone had my same problem
or otherwise knows what's going on?

Regards,
Fabio

Hello,

I know that behavior of clients, where the portmap service is not
running on the client machine.

Please check that and let me know...

Portmap is running, and in /var/log/messages I get a line like this when
I try to mount the exported directory on the server itself:

May 23 13:40:55 localhost rpc.mountd: authenticated mount request from
localhost:972 for /tftpmount (/tftpmount)

Hi,

The next thing is if you are trying to mount it from the local server
which isn't normally a problem. Then you should check again your
settings in /etc/exports.

create a /etc/exports which looks like that:

/tftpboot 10.0.0.0/255.255.255.0(rw,sync,no_root_squash)

After that restart the nfsserver...

Most probably it will work now...

Let me know please. It's always nice to get a feedback. Thanks in
advance...

Yes, as said I've tried mounting it from the local server too, and I get
always the same error.

Mmm, well, I'm not sure why you suggest I should change that - specially
because I've not told you my subnet address and network mask - but
anyway, even if I change it that way I get the same problem.

Nope, sorry, it didn't :-/
