Do both amito and weather have gateway.2wire.net as their domainname?

Did amito's firewall rules change with the upgrade?!

What's the output, on amito, of 'rpcinfo -p weather'?

Does 'mount -t nfs -o nfsvers=3 weather:/ /srv/weather' succeed?

You can mount with '-v' to get a more verbose failure.

(Do you mean "weather:/var ..." or "weather:/home ..." in fstab?)
