pub fn firewall_hint(port: u16, needs_http01: bool) -> Option<String>Expand description
The firewall this machine runs, and the one line that opens a port.
Detected and printed, never run. Opening a port is a change to how much of this machine the internet can reach, and that decision is not one a convenience command gets to make silently — even when it is obviously the right one, which it usually is.
