Just remembered something else: do you jexec into the jail, or do
you do a proper logon (eg. ssh into the jail). I think that if you
jexec into the jail and then try to ssh, you might have a problem
because you aren't really logged in to the jail and thus have no
(psuedo) tty associated with your session..
