console.handlers

console.handlers(5)					   System Administrator's Manual				       console.handlers(5)

NAME

       console.handlers - file specifying handlers of console lock and unlock events

DESCRIPTION

       /etc/security/console.handlers determines which programs will be run when an user obtains the console lock at login time, and when the user
       loses it on log out. It is read by the pam_console module.

       The format is:

       handler-filename lock|unlock [flag ...]

       Where handler-filename is a name of the executable to be run, lock or unlock specifies on which event it should be run, and  flags  specify
       how should pam_console call it.

       Additionally there should be a line which specifies glob patterns of console devices.

       The format of this line is: console-name consoledevs regex [regex ...]

       Where  console-name is a name of the console class - currently ignored - and regexes are regular expression patterns which specify the name
       of the tty device.  Only the first such line is consulted.

FLAGS

       logfail
	      The pam_console module should log error to the system log if the return value of the handler is not zero or if the handler  can  not
	      be executed.

       wait   The pam_console should wait for the handler to exit before continuing.

       setuid The handler should be executed with uid/gid of the user which obtained the console lock.

       tty    The handler will get a tty name as obtained from PAM as a parameter.

       user   The handler will get an user name as obtained from PAM as a parameter.

       Anything else will be added directly as a parameter to the handler executable.
