Jail login

jlogin command

			% cbsd jlogin


Performs a login to the jail as root user. If the jail isn't present on the local node, but rather on one of the remote nodes, jlogin will attempt to login over ssh.

If no jail is specified, a list of all known online jails in the farm is displayed (provided remote hosts were added).

If you remotely connect to a jail and node which have tmux installed, tmux will be launched at login and the session is given the name taken from the server's nodename (taken from jlogin).

Additional sessions will automatically join the tmux session through a tmux-attach. When the last connection is closed the tmux session ends (you may detach via Ctrl + b , d to keep it running).

Should you prefer NOT to use tmux on jlogin, copy ${workdir}/defaults/jlogin.conf to ${workdir}/etc/jlogin.conf and set tmux_login to 0.

In order to deactivate "try to login?" when logging in to remote nodes, set always_rlogin to 1 in your ${workdir}/etc/jlogin.conf.


			% cbsd jlogin kde4

Starting with the version of CBSD 11.1.2, you can customize the command, redefining the action on you more suitable

This is achieved through the configuration file blogin.conf and the parameter login_cmd.

The file can be placed for the individual environment in the directory $workdir/jails-system/$jname/etc, and globally, overwriting the value from $workdir/etc/defaults/blogin.conf. To do this, create a file with your configuration in the directory $workdir/etc/

With a custom call, you can use CBSD variables - for this or that environment

For example, if you want instead of the standard behavior, when the blogin lauched ssh client, the file $workdir/etc/blogin.conf can look like this:

		login_cmd="/usr/bin/ssh your_user@${ipv4_first}"
