You cannot have multiple processes listen on the same address and port, no matter whether they're in a jail or not. If this patch for multiple IP numbers in jails breaks that behaviour, then it does not fix INADDR_ANY behaviour, despite what the subject says. :-) > # /usr/sbin/sshd -p 666 > # jail / temp <yourip> /usr/sbin/sshd -p 666 That last command _must_ fail with errno EADDRINUSE.
