Имя (Name)

pam_tty_audit - Enable or disable TTY auditing for specified users

---

Синопсис (Synopsis)

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

---

Описание (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.

---

Параметры (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?).

Предоставляемые типы модулей (Module types provided)

Only the session type is supported.

---

Возвращаемое значение (Return value)

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

PAM_SUCCESS Success.

---

Примечание (Note)

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.

Примеры (Examples)
