OK, I changed the host sshd_config setting, now I can ssh into the
jailed system.

Here is what I've done:
twp1:~ # !jexec
jexec 5 /bin/sh
# top
kvm_open: /boot/kernel/kernel: No such file or directory
# cd etc
# cat rc.conf
network_interfaces=""
rpcbind_enable="NO"
sshd_enable="YES"
syslogd_flags="-ss"

mysql_enable="yes"
mysql_limits="yes"
mysql_dbdir="/usr/local/var/db/mysql"

# hostname
twp5
#
twp5 is the jailed system.
Strange, I remember last time I can still have sshd and mysql running
in the jailed system.

Thanks
