Port 80 premission denied

Hi,

I want to run ruby on rails on port 80 but got permission denied error. I don't want to start server as root so how to add user permissions to start server on port 80? Can you help?

Re: Port 80 premission denied

What have you tried?

A quick google search suggests that setcap can be used to allow certain executables bind to the usually protected ports 1-1023). Other hits suggest redirecting the incoming connection on port 80 to another, unprotected port. Have you tried these suggestions?

I saw that i can do some port mapping. But port mapping looks like hack/workaround. It is not enough to add user to proper group?

I tried to add user to networking group(no success). In google i found solution to map port to 80(didn't try). Port mapping is the only solution?

Re: Port 80 premission denied

Are you trying to run your ruby on rails website as a regular user?

I would suggest running it on a different port (>1023) as a regular user.
Then I would suggest setting up a separate HTTP server (with lighttpd or nginx) that acts as a reverse proxy listening on port 80.

EDIT Of course one could also try to shoehorn one's OS into allowing users to open ports in the range [1-1023], but I thought I'd also give a little more elegant solution.
