Closing port 631 (IPP)

jrdioko · 11-13-2005, 02:18 PM

What needs to be done to stop IPP from listening on port 631? I understand this is needed for CUPS to let you use the web interface, but is there a way to stop it and still be able to print using CUPS? If so, is there a way to temporarily start it again to use the web interface for a short period of time?

Thanks.

There are quite many options in cupsd.conf. Not exactly what you want maybe, but you definitely can restrict the access.

I've looked in cupsd.conf and it's not clear to me what needs to be done, as I don't really understand how much of the server aspect of CUPS is needed to print. I'd like to be able to continue printing through my direct usb connection to the printer, but close this port and not allow remote access. What changes do I need to make to cupsd.conf to do this?

Comment the line with "Listen" to

Code:

#Listen *.631

then add

Code:

Listen 127.0.0.1:631

Then the port is closed to the world and CUPS is still listening locally.
