Just a thought on your c3 issue... If a remote command takes forever to execute, it's typically because there is a bad name server in /etc/resolv.conf. It takes a long time for the first nameserver to fail (timeout) and then trickle to the next nameserver (repeat til you find one that works!).
So, check /etc/resolv.conf for bad juju...
