No.  gpsfake is not supposed to ever use the default as that would
conflict with a running gosd.

Weird.

Notice it is bound to 127.0.0.1?  You tried to connect with:

> kalach@kalach1:~/gpsd$ ./gpsd -N gpsd://192.168.10.10

But gpsd is not listening on 192.168.10.10!

You need to tell gpsfake to tell gpsd to use the -G option to listen
on an IP that is not localhost.

That is a much easier problem to fix.

Easy to fix.
