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