The path aboev is 109 characters. Can this limit please be raised to a higher number, perhaps 256, to ensure such union address can be used as hostnames? A workaround is to use '-S none' to disable the control socket, but it is quite a a blunt hammer, and I thought it might be worth a try to ask if you could raise the size limit instead. -- Happy hacking Petter Reinholdtsen

Sorry, this is a Linux API limitation and not something that OpenSSH can change. See unix(7). Given what you've posted, you could probably work around it by shortening the path prefix in ControlPath. Not pretty, but it would let you use onion addresses here. -- Colin Watson (he/him) [[email protected]]
