In the previous item, we saw how to build, start and stop a jail. The rc scripts allow us to easily start and stop a jail.
Starting the jail (from the host):
slackbox# /etc/rc.d/jail onestart server Configuring jails:. Starting jails: server.erewhon.net.
Then log into the jail via ssh;
slackbox# ssh 192.168.0.100
Closing the jail (again from the host);
slackbox# /etc/rc.d/jail onestop server
For this to work, the following has to be set in /etc/rc.conf:
# For jails # Do not start automatically jail_enable="NO" # General jail options jail_list="server" jail_interface="rl0" jail_devfs_ruleset="devfsrules_jail" jail_devfs_enable="YES" # Specific options for the jail 'server'. jail_server_rootdir="/home/jails/192.168.0.100" jail_server_hostname="server.erewhon.net" jail_server_ip="192.168.0.100"
See /etc/defaults/rc.conf for an overview of all the settings that can be used.
