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.
Only the session type is supported.
When TTY auditing is enabled, it is inherited by all processes started by that user. In particular, daemons restarted by a 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.
The patterns are comma separated lists of glob patterns or ranges of uids. A range is specified as min_uid:max_uid where one of these values can be empty. If min_uid is empty only user with the uid max_uid will be matched. If max_uid is empty users with the uid greater than or equal to min_uid will be matched.
Please note that passwords in some circumstances may be logged by TTY auditing even if the log_passwd is not used. For example, all input to an ssh session will be logged - even if there is a password being typed into some software running at the remote host because only the local TTY state affects the local TTY auditing.
Audit all administrative actions.
