TIL CUPS, the print queue server came from Apple and enables a web server by default (port 631) on a lot of #Linux systems. Is this really a good idea?
@tomosaigon It's bound to localhost, (not 127.0.0.1) and inaccessible from the network. It can be *made* so, but it must be explicitly done so.
@tomosaigon Yes and no.
> the server has to bind to an ip address, not a hostname, so it actually is 127.0.0.1 is it not? Practically speaking, how is it different?
Yes, practically speaking, localhost == 127.0.0.1. In the case of CUPS, it is *only* listening for requests from the local system. Any other requests are dropped by default.
