It's been a while since I experimented with jails but I'm pretty sure it is the reason I changed my sshd_config When you start sshd on the base system by default it binds against 0.0.0.0 and :: which is every ip4 and ip6 address configured on the base system, which includes the aliased ip's for your jails. This is represented by the *:22 from sockstat. When you start the jail it can't start sshd because the base already has that address/port in use. In /etc/ssh/sshd_config comment out the ListenAddress 0.0.0.0 and ListenAddress :: then add ListenAddress 10.0.0.3 service sshd restart start your jail and try again The jail config is fine as the jail only sees the one ip address assigned to it.
