Question
Mac OS X - Port 80 Permissions
I have written a small webserver in Java and am trying to get it to run on port 80 in Mac OS X. I get a "java.net.BindException: Permission denied" error which must mean that the logged-in user does not have permission to open a port on 80...or anything below 1024 for that matter. Now my question is this:
1) Is is possible to change the user permissions on Mac OS X to allow this? If so, how are they changed?
2) If they cannot be changed, is running it from root the only way to get it to bind to 80?
Thanks,
David

As far as I know there are no limitations on which ports a user can open. You can test this by trying to bind to a different port below 1024. You could also try to startup your application as root to see if the problem still persists.
By default Mac OS X has the apache web server running which binds to port 80 during boot. You can switch the web server off from the System Preferences -> Sharing. It's labeled as "Personal Web Sharing". If apache is already running then you are not allowed to bind another service to the same port.
