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.
