PAM_TTY_AUDIT(8) Linux-PAM Manual PAM_TTY_AUDIT(8)
pam_tty_audit - Enable or disable TTY auditing for specified
users
pam_tty_audit.so [disable=patterns] [enable=patterns]
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.
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?).
Only the session type is supported.
PAM_SESSION_ERR
Error reading or modifying the TTY audit flag. See the system
log for more details.
PAM_SUCCESS
Success.
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.
Audit all administrative actions.
