jail and networking

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 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 and 
ListenAddress :: then add ListenAddress

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.
