Dialog to configure the CUPS server network
settings
Look for hostname on IP addresses

Whether or not to do lookups on IP addresses to get a fully-qualified hostname. This defaults to off, for performance reasons.

Port

Enter here Ports and addresses that the server will listen to. The default port 631 is reserved for the Internet Printing Protocol, and is what we use here.

You can have multiple entries, to listen to more than one port or address, or to restrict access.

Note

Unfortunately, most web browsers don't support TLS or HTTP upgrades for encryption. If you want to support web-based encryption, you'll probably need to listen on port 443, the HTTPS port.

Use the Add and Remove buttons to add and remove entries from the list.

You can enter ports on their own, e.g. 631, or hostnames with ports, e.g. myhost:80 or 1.2.3.4:631.

Max request size

Controls the maximum size of HTTP requests and print files. The default setting is 0, which disables this feature.

Timeout

The timeout (in seconds) before requests time out. The default is 300 seconds.
