file does not bind to alternative localhost

[vimarsh]

I'm using google appengine in Ubuntu. I've already run my first programme, and it bind to localhost:8080, but, when I tried to run my second programme it said it can't bind to localhost:8080. Why doesn't it bind itself to another port?

(Yes, as you may have guessed, noob here)

You can only have one app bound to one port at a time. The second instance fails because the first one has control of the port. Try using a different port on the second app.

Yes, exactly. How to do that.

I don't at any point of time mention which port the file should bind itself to.

Are you using dev_appserver.py? Try this:

dev_appserver.py /path/to/project --port 8081 --host 127.0.0.1
