I was trying to use hosts.deny for this, and it clearly does not work
the way I thought it did. I thought that I could block rpcbind using 

rpcbind: ALL 

but my external nmap scan still found rpcbind running. Oh well. I do
not need rpcbind so I just uninstalled it. 

Probably I should investigate iptables so that other services I
accidentally install do not open up security holes. I have never
enjoyed working with it, though.
