pam_tty_audit
PAM_TTY_AUDIT(8) Linux-PAM Manual PAM_TTY_AUDIT(8) NAME
pam_tty_audit - Enable or disable TTY auditing for specified users SYNOPSIS
pam_tty_audit.so [disable=patterns] [enable=patterns] 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. 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?). MODULE TYPES PROVIDED
Only the session type is supported. RETURN VALUES
PAM_SESSION_ERR Error reading or modifying the TTY audit flag. See the system log for more details. PAM_SUCCESS Success. NOTES
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. EXAMPLES
Audit all administrative actions. session required pam_tty_audit.so disable=* enable=root SEE ALSO
