listen on localhost:8000: [Errno 98] Address already in use.

[Sameer Regmi]

I installed codenode, and when I do
$ codenode-admin run

I get error message :
2009-11-20 13:05:02-0800 [-] twisted.internet.error.CannotListenError:
Couldn't listen on localhost:8000: [Errno 98] Address already in use.

Could you let me know how I can solve this.

Could you let me know how I can solve this.

You already have another program listening on the port "8000".
Maybe another running Codenode instance? Just stop that one and
start the other.


To choose another port, you have to use "twistd', which "codenode-admin"
is a wrapper of (I consider this a bug / missing feature, and we'll fix this).
If you want to use twistd right now, I can explain how to do that if needed.

Yes we have another program (website) listening on that port and I should not stop that so I need to choose another port.

Yes, could you explain that to me. Thank you very much.

I just remembered an easier way of changing ports is to edit the "APP_PORT" settings option
in the file "frontend/settings.py" in the directory that is create when you did
"codenode-admin init -name mycodenode".


The better way is for someone to improve this function:
http://github.com/codenode/codenode/blob/master/codenode/management/commands.py#L50
to allow the passing of the frontend port. It could be a fairly easy first patch if you feel up
to it :-) - else just use the settings file.
