Let me see if I can explain a little better. The issue (I think, based on what you've told us) is that you have a user on System A that is trying to modify a file (via an NFS mount) on System B. Keep in mind here that in effect user A is simply trying to change a file on System B. If user A doesn't have /permission/ to change that file on System B he won't be able to. The fact that NFS is set to RW gives him the capability to change the file, but only if he has the correct permissions to that file. Does that make sense? In effect the user accounts on System A and System B must be identical (not exactly, but or this, let's keep it simple) in order for this to work. This means UIDs and GIDs. If you have two user accounts 'Bob' (one on each system), and the UIDs don't match, then even though Bob can mount the filesystem via NFS, he won't be able to modify the file since the UIDs don't match. Really, this isn't an NFS issue, so much as a file permissions issue ON THE SYSTEMS. Do this, have that user log into the NFS server via ssh and see if he can modify the file that you are having trouble with. If I'm right, he won't be able to that way either. You know, after reading this to myself, I realize how crappy it sounds. I'll be glad to work with you offlist since I deal with NFS a lot. -- <div><div></div><div>Libenter homines id quod volunt credunt -- Caius Julius Caesar Mark Haney Sr. Systems Administrator ERC Broadband (828) 350-2415 Call (866) ERC-7110 for after hours support -- ubuntu-users mailing list <a href="mailto:ubuntu-users@lists.ubuntu.com" target="_blank">ubuntu-users@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-users" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-users</a> </div></div></blockquote></div> hey mark thankyou for the mail and now its seems working this is the etc/export on the server /home/users <a href="http://10.4.139.3" target="_blank">10.4.139.3</a>(rw,no_root_squash,async) /srv <a href="http://10.4.139.3" target="_blank">10.4.139.3</a>(rw,no_root_squash,async) and the clients etc/fstab is 10.4.139.2:/srv /srv nfs rsize=8192,wsize=8192,timeo=14,intr 10.4.139.2:/home/users /home/users nfs rsize=8192,wsize=8192,timeo=14,intr this is working at the moment but i dont know wen it will stop working :) donny </div>
