Hi, folks.  I have a question about the caServer as provided by the
pcaspy python package.  I hope this is an appropriate place to ask.

I'm wondering how to specify the network that the caServer binds to.  If
I run the example/dummy.py server script that comes with the source, it
works fine if I have an active outward-facing network interface.
However, if I'm offline I get the following error:

servo:~/src/pcaspy/git 0$ python ./example/dummy.py 
filename="../../../../src/cas/io/bsdSocket/casDGIntfIO.cc" line number=121
server isnt attached to a network - unable to continue
filename="../../../../src/cas/io/bsdSocket/caServerIO.cc" line number=131
Attempt to set server's IP address/port failed unable to attach any interface
filename="../../../../src/cas/generic/caServerI.cc" line number=62
server isnt attached to a network - CA server internals init unable to continue
terminate called after throwing an instance of 'int'
Aborted
servo:~/src/pcaspy/git 0$ 

Presumably it's trying to bind to an interface that doesn't exist or is
not configured.  I would like to specify that the server just bind to
the loopback interface.  Does anyone know accomplish this?

Any advice would be great appreciated.  Thanks!

jamie.
