Listening on port 55550
Posted on 2015-02-07
I have received a simple server python script from a contract developer that I am trying to set up on a local computer for testing. The script is set up to listen on port 55550 which I am having trouble with. I have attempted to set up port forwarding on my linksys router but every time I attempt to test with the script I get an error associated with port 55550. I have tried running port scanners against my internet IP address but I cannot find any open reports. I assume my ISP blocks port scanning at the service level because every port I scan fails.
What I am trying to figure out is whether or not port 55550 has access through my ISP, if not I need to find an alternate port that I can modify the python script to listen on. The python script is listening for a REST protocol communication from a mobile device that is outside my local network that the script is running on.
How do I figure out if port 55550 is available through my ISP? If this port is not an option because of some restriction my ISP has established, how do I find other open ports that I can use?
My ISP is Windstream DSL. I have tried to find information on their technical pages but have had zero luck. I had even less luck speaking with someone in their technical support center.
