PAM_TTY_AUDIT(8)						 Linux-PAM Manual						  PAM_TTY_AUDIT(8)

NAME
       pam_tty_audit - Enable or disable TTY auditing for specified users

SYNOPSIS
       pam_tty_audit.so [disable=patterns] [enable=patterns]

DESCRIPTION
       The pam_tty_audit PAM module is used to enable or disable TTY auditing. By default, the kernel does not audit input on any TTY.

OPTIONS
       disable=patterns
	   For each user matching one of comma-separated glob patterns, disable TTY auditing. This overrides any previous enable option matching
	   the same user name on the command line.

       enable=patterns
	   For each user matching one of comma-separated glob patterns, enable TTY auditing. This overrides any previous disable option matching
	   the same user name on the command line.

       open_only
	   Set the TTY audit flag when opening the session, but do not restore it when closing the session. Using this option is necessary for
	   some services that don't fork() to run the authenticated session, such as sudo.

       log_passwd
	   Log keystrokes when ECHO mode is off but ICANON mode is active. This is the mode in which the tty is placed during password entry. By
	   default, passwords are not logged. This option may not be available on older kernels (3.9?).

MODULE TYPES PROVIDED
       Only the session type is supported.

RETURN VALUES
       PAM_SESSION_ERR
	   Error reading or modifying the TTY audit flag. See the system log for more details.

       PAM_SUCCESS
	   Success.

NOTES
       When TTY auditing is enabled, it is inherited by all processes started by that user. In particular, daemons restarted by an user will still
       have TTY auditing enabled, and audit TTY input even by other users unless auditing for these users is explicitly disabled. Therefore, it is
       recommended to use disable=* as the first option for most daemons using PAM.

       To view the data that was logged by the kernel to audit use the command aureport --tty.

EXAMPLES
       Audit all administrative actions.
