Bug#733658:

[Armin Müller <nimra123de@yahoo.de>]

Hi,
got exactly the same beahviour.
but i got the rpcinfo in both pathes, in
> usr/sbin/rpcinfo guess from the package libc-bin
> usr/bin/rpcinfo guess from the package rpcbind

root@disaster:~# rpcinfo -u localhost nfs 3
rpcinfo: RPC: Port mapper failure - Authentication error
program 100003 version 3 is not available

Doesn´t matter which rpcinfo i use, i got the same output from both.

I just comment the Line 121 from /etc/init.d/nfs-kernel-server out:
#RPCMOUNTDOPTS="$RPCMOUNTDOPTS --no-nfs-version 3"

So now i can use nfsv3, but i guess thats not what it should be.
