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 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 don't fork() to run the authenticated session, such as sudo.
MODULE SERVICES PROVIDED
Only the session service 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.
EXAMPLES
Audit all administrative actions.
session required pam_tty_audit.so disable=* enable=root
