NAME

pam_tty_audit - Enable or disable TTY auditing for specified users

CONTENTS

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.
