Hi, I think then you have some other problem. I faced a similar problem when the console would say something like this - either login incorrect or user name not found. All I did to make it work is a host $chmod -R 777 <path to targetrfs> host $chown -R root <path to targetrfs> (I donno whether this makes sense since root can however override??) Following this give a host $/usr/sbin/exportfs -av host $/sbin/service nfs restart host $/etc/init.d/iptables stop and invariablly this happened when I compiled/made changes inthe rfs (mostly switching between user and root) Maybe the mechanism is different with ubuntu- some one using ubuntu c(w)ould throw more light.

This especially happens if you switch between root and <user> frequently. Try chowning the rootfs to the appropriate user once again. Hope this may land up in some clue.
