You better block the RPC portmapper from outside connects or even shut
the service down if you don't run an NFS server.

TCP connections from outside to MySQL shouldn't be necessary either.

What the portscan service reported you about ports 21 and 23 can't be
true due to what your nmap run reports. Though running nmap on localhost
is not that much reliable. Better nmap from outside to get results like
any other from outside would see.
