Cannot register service: RPC: Unable to receive
While creating my NFS server, I stumbled around the error "Cannot register service: RPC: Unable to receive". After searching a while I found out that this problem was caused by PortSentry which prevented PortMapper to start. Stopping PortSentry solved the problem.
So, if you find yourself in the same position just shutdown portsentry by:
[code]
/etc/init.d/portsentry stop
[/code]
