I have a gui-less flowgraph that runs in the background with sudo
privileges. While I can run ControlPort normally from GRC, it doesn't seem
to work properly with my backgrounded FG - I get timeout errors. My config
files are setup so that both FGs do actually call ControlPort and Perf Mon
(verified in log files). The FG and the monitoring apps are all running on
the same PC.
Setup is Ubuntu 12.04 x64 with GR 3.7.4, built on the weekend.
Attempting to run Perf Mon, I get:
$ gr-perf-monitorx 127.0.0.1 23456
2014-05-22 11:01:54.450720 /usr/bin/gr-perf-monitorx: error: Traceback

{
}
Attempting to run Ctrl Port Mon, I get:
A blank canvas screen like this: http://i.imgur.com/8N88fcU.png
and console output like:
$ gr-ctrlport-monitor 127.0.0.1 23456

ctrlport-monitor: radio.get threw exception (exception

{
}).
...
My ctrlport.conf file has just one uncommented line:
ControlPort.Endpoints = tcp -t 5000 -h 127.0.0.1 -p 23456
I had extended the timeout, attempting to resolve the problem, but had no
luck.
Very Respectfully,
Dan CaJacob
