Before you can successfully run pysiriproxy you must first follow the complete installation instructions.
After pysiriproxy has been installed you can run the following commands to start pysiriproxy:
$ cd /opt/pysiriproxy
$ sudo ./pysiriproxy
Note
pysiriproxy must be run with sudo because it binds to a port that is less than 1024, and needs root privileges to do so.
