You may have these on a non-connected lan.

Maybe the method that has the most chances of returning the correct
result would be to look for a default route in the output of 'route'. I
think the way to recognize it is to look for:
- a genmask of 0.0.0.0
- check that the Flags contain 'U'
I don't know how portable this is. 'route' may return things in a
different format on Solaris for instance. In particular I've seen
Solaris machines for which 'route' returns nothing and yet they have a
functional internet access. I'm still puzzled by this one.
On Linux you can also parse /proc/net/route, not that it's more
portable, but it saves the creation of a process.
