Overview
The SecureTTY service module for PAM, pam_securetty provides functionality for only one PAM category: account management. In terms of the module-type parameter, this is the “account” feature. It also provides null functions for authentication and session management.
SecureTTY Account Management Module
The SecureTTY account management component (pam_sm_acct_mgmt()), returns failure if the user is attempting to authenticate as superuser, and the process is attached to an insecure TTY. In all other cases, the module returns success.
A TTY is considered secure if it is listed in /etc/ttys and has the TTY_SECURE flag set.
The following options may be passed to the authentication module:
debug-
syslog(3) debugging information at LOG_DEBUG level.
no_warn-
suppress warning messages to the user. These messages include reasons why the user's authentication attempt was declined.
