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 matchin 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 dont fork() to run the authenticated session, such as sudo.
Only the session service 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.
Audit all administrative actions.
