twisted.internet.error.CannotListenError: Couldn't listen on any:80: [Errno 13] Permission denied
I am currently working on a project to create a TCP server on mac os mountain lion. I wrote a script called: Server.py
Within this python script, I used twisted to listen upon port 80 as shown below:
reactor.listenTCP(80, factory)
reactor.run()
How ever I am getting errors as such:
File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/twisted/internet/posixbase.py", line 436, in listenTCP
p.startListening()
File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/twisted/internet/tcp.py", line 641, in startListening
raise CannotListenError, (self.interface, self.port, le)
twisted.internet.error.CannotListenError: Couldn't listen on any:80: [Errno 13] Permission denied.
I am thinking is it because the tcp.py script has the wrong permission for admin user? or is there a way to set permission on the port < 1024? (To change the permission, how would it affects the security of such a server?)
Any better solutions is apprieciated.
Answer
Just go to the terminal and type sudo python server.py. Now it will ask password, type your password. Your problem will be solved. Happy coding
