Running MIDAS at CERN is proving more challenging than I expected. The network environement is not
as benign as I am used to (i.e. at TRIUMF) and our machines are being constantly probed by something/
somebody.

08 Jun 2007, Stefan Ritt, Suggestion, RFC- ACLs for midas rpc, mserver, mhttpd access

First I have a general question: mserver is started through xinetd, and xinetd has
the options "only_from" and "no_access". This is equivalent to the tcp_wrapper
functionality. Why not using this? It's possible without changing anything in midas.
