Hi,
showmount -e fails on an NFS server (CentOS with RPCMOUNTDOPTS="-N 1 -N 2")
whose mountd offers NFSV3 only and Debian's showmount seems to speak NFSV1
only. In the rpcinfo -p output below, the latter is the CentOS box.

That's the showmount error message:
tkorber@exdpr:~$ showmount -e storeob-ha02
rpc mount export: RPC: Program/version mismatch; low version = 3, high version = 3
I think it would be a good idea to make also showmount speak NFSV3.
Here's a patch against the version in Lenny:

I believe this has been fixed a long time ago around 1.1.5 upstream
version.
