Hi Graham. 

Whether or not you are connected to the internet isn't really the issue, is it? 
All that means is that you have a route to the WAN port of your edge router. I 
mean, the real issue is finding out if you can reach a particular server on a 
particular port using DNS, or else a given IP address, whether or not it is "on 
the internet". That is I think, what you really mean. 

The code I posted, while it has some exterraneous code dependent on sqlYoga 
calls, neverless is a framework for doing that. 

1. Outer loop to allow user to retry (not strictly necessary but it lets the 
user attempt to fix the problem before dumping him).
2. Inner loop to open socket to prescribed server (Not necessary either, but 
you may want to check multiple times for the open socket in case of slow 
connections, and timeout after x tries).
