Not exactly related, but I run an unraid game server for friends and use a lot of the preconstructed docker apps for games.
Most of them come with the server name preset and the server password preset.
I’ve jumped into many a “private” server called Docker-GAMENAME with the password still set to “Docker”
I think it was some XMPP related server I ran quite a few years ago which had ‘i_have_read_the_manual = 0’ or something similar buried into default configuration file. And it would just silently exit if that variable was not set properly.
Maybe we need more things like that.
