PaperCut uses the Application Server to manage user and account information, manage printers, calculate print costs, provide a web browser interface to administrators and end users, and much more. See Stop and start the Application Server. Test and ensure the web interface is working. On Linux systems, only privileged programs that run as root can use ports under In line with security best practice PaperCut runs as a non-privileged user.
Enable ports 80 (HTTP) and 443 (HTTPS)
To enable port 80 and , use iptables or ipchains on old systems to port-forward 80 to The following commands provide an example. Consult your distribution's documentation to see how to persist the iptables rules between system restarts:. These commands would typically be placed in an rc init script or the iptables startup config script as provided by your distribution.
When you are done, restart the Application Server.

Another option may be to disable the proxy from starting in the first place. You must be logged in to post a comment. Will ask if ok to overwrite existing file if present. Changing the virtual host macros not required, but keeps things consistent. Stop for any errors. Connected to localhost. Wait, I hear you say, you can find that with lsof or netstat.
Try lsof -i grep http What will be a problem is that lsof needs root privs to see other users' processes, so you should use sudo lsof -i and I'd try it without the grep , just to make sure Hi all, thanks for the suggestions so far, but hasn't turned up anything - even as root, and without greps, there is nothing listed as actually listening to port Did you try lsof -i while still connected in that Telnet session? Again, I know: even if you figure it out that way, it would not be the answer to your question You need to run these commands as root to show other users' processes, for example: sudo lsof -i '' Mac OS X includes an Apache web server that can be controlled using apachectl as root.
According to Wikipedia : When launchd scans through the job plists at boot time it reserves and listens on all of the ports requested by those jobs. So then I guess my idea was right that sudo lsof -i '' might not actually return anything, unless one runs that while connected in the Telnet session? I believe your answer is probably the solution; it just doesn't match all comments from the OP.

Thanks for this brilliant answer. I've now managed to solve it: 1. There was a mistake in httpd. But launchd was listening on port 80, ready to forward requests to a non-existent server. However launchd wasn't listening in the conventional sense - that is - the results of sudo lsof -i was blank, likewise for netstat 4.

I guess launchd does some magic like xinetd in that it doesn't officially listen on a port, but somehow manages to allow connections to the port by bribing the kernel. For me what solved the issue was running sudo apachectl stop in the terminal. This did not work for me, but this version did show what was running OS High Sierra Just to make the actual answer clear in case users are searching for this.
