Linux NFS connectivity question.

(And, yes, this is in the right forum as you will shortly discover.)

We have a mix of FreeBSD and Linux machines here at work now, but there are some ... curious networking issues. The main one I wanted to ask about was NFS: none of our FreeBSD clients can moutn Linux NFS exports. The error given on the client is "permissions denied" and the log entry on the Linux server looks like this:

rpc.mountd: refused mount request from 10.0.0.12 for /home2/files (/): no export entry

A successful mount from a Linux client looks like this:

rpc.mountd: authenticated mount request from 10.0.0.153:617 for /home2/files (/home2/files)

Googling hasn't helped. Documents found suggest adding insecure to the export or adding -P to the mount command to connect from a privileged port. Neither change the error message.

Any clues?

Questions

I just tried mounting a Linux export from an old FreeBSD box. It worked.

1. What is your mount command?

2. What does your exports file look like?

I did not have any problems with exports as:

/home/pictures 192.168.0.0/255.255.255.0(rw,no_root_squash)

and this mount command (from freebsd):

mount dual:/home/pictures /mnt

What vewrsion of NFS you using...

NFS v2 support from Linux is Okay... Has a set of issues...

NFS v3 support from Linux is Okay... Has a different set of issues...

What do the Exports look like in /etc/exports

Are you running lockd on the Linux box?

And are the "Secure or Insecure" mount requests? If they are secure, Someone has to login that has rights to the export from the machine doing the request... or you have to tell it (the exporter) to allow anyway...

NF S Versions

Some NFSen can export a subdirectory. Others only allow a complete filesystem.

Boot to the head...

Turned out to be a silly problem in /etc/exports. If the server knows the requesting client by *name* - e.g. in /etc/hosts - then you have to include the *name* of the client in /etc/exports; the IP address doesn't work.

NFS versions? Dunno.
lockd? Yep.

Exports line: /home2/files 10.0.0.*(rw,root_squash,sync,anongid=401)
I duplicated the line and replaced the 10.0.0.* with the name of the client (and did exportfs -a) and it worked.

The mount command was: mount isengard:/home2/files ./files
which worked after I changed the exports list.

Thanks everyone, anyway.

What I like best about that.

a) the fix makes sense (usually) b) the fix tends to stay fixed!
