Hey Dan,
When you're running the flowgraph that you're trying to connect to over
ControlPort, can you verify that they are setting up the correct endpoint?
If you run it yourself, not as a background task, it should print out
information about the endpoints. That will tell you the port number. Just
want to check to make sure your config file is getting read correctly and
setting it up on port 23456 like you specified.
We really should move the endpoint information to be sent out by the gr-log
system so you can redirect the info to a file and see the info without
requiring you to have access to stdout.
