NFS server and mapping of user ids

[mgiann]

Hello,

I have my sheevaplug setup with ubuntu 9.04. I have nfs-kernel-server installed and running.

Now, I want to set setup the nfs server in a way that it maps user ids from my laptop to the shevaplug. I found that this can be done with the map_static option in the /etc/exports file. However this option seems to be available only in the nfs-user-server. I cannot find this package.

Has anybody here done such a setup?

Is it sufficient if I compile and install this package: http://packages.ubuntu.com/source/intrepid/nfs-user-server? Is it safe to do so and how do i revert this if things go wrong?

Thank you

if your laptop understands it, you can use nfsv4. It does userid-mapping by name and is a lot less hassle. Just create a user with the same _name_ on the plug (id does not matter). nfsv4 will do the mapping.

Or keep your user-ids manually in sync. If it is only you and your laptop that should not be too hard.

Thats a great feature for nfsv4, I didn't know of.

It does work with a linux nfs client (opensuse 11.2). However I couldn't make it work on Mac OS X 10.6.4. Has anyone succeeded in configuring this in Max OS X?

Any other alternatives that can work on the mac?

I'm currently running an NFS server on my SheevaPlug to several Mac OS X clients.  I've set it up so that everything maps to a single user on the plug (so basically world-writable by everybody, which is okay since it's just my LAN) -- if you think this setup would work for you I can give you the details on getting Mac OS X to cooperate.

that's squashing all ids. You can also try ugidd, but this needs to be run on the client, i wouldn't go this way. Either sync the ids or go for nfsv4

On the mac, nfsv4 support is described to be in alpha. I tried it against the nfsv4  server on the sheevaplug and didn't work.

Does anyone else have a different experience?

This is what I'm trying to do; more specifically to do Time Machine ( or rsync ) backups from a couple of MacBooks to a NAS attached to my plug which is running Debian Squeeze.

Any details gratefully received.
