Re: [whimsy] branch master updated: Add test for Whimsy master

[sebb AT ASF <se...@apache.org>]

The code below works for the current vm3/vm4 hosts.
But there are lots of ways to set up a system, and it may be that some
setups won't return the external address for the local hostname.
i.e. getaddress() might return the local network address.
In fact that is what happens if one uses Resolv.getaddress() instead.

Since no diff mails will be sent if there is no master, it occurred to
me that it might be sensible to put the code into a utility that can
be checked by Ping My Box?

Thoughts?
