However, since no obvious changes around "localpeer" handling occurred between 2.4.15 and 2.4.22 it looks like your previous system (ubuntu 18.04) behaved differently and used to return "s017.domain.local" with gethostname() and 'hostname' command (without the -f) (Please note that hostname command relies on uname() internally, and not on gethostname(), but the manual confirms that hostname command without arguments "will print the name of the system as returned by the gethostname(2) function.") Could you confirm? Thanks
