NAME

     pam_echo -- Echo PAM module

SYNOPSIS

     [service-name] module-type control-flag pam_echo [arguments]

DESCRIPTION

     The echo service module for PAM displays its arguments to the user, separated by spaces, using the current conversation function.

     If the % character occurs anywhere in the arguments to pam_echo, it is assumed to introduce one of the following escape sequences:

     %H    The name of the host on which the client runs (PAM_RHOST).

     %s    The current service name (PAM_SERVICE).

     %t    The name of the controlling tty (PAM_TTY).

     %U    The applicant's user name (PAM_RUSER).

     %u    The target account's user name (PAM_USER).

     Any other two-character sequence beginning with % expands to the character following the % character.

       pam_echo - PAM module for printing text messages

SYNOPSIS

       pam_echo.so [file=/path/message]

DESCRIPTION

       The pam_echo PAM module is for printing text messages to inform user about special things. Sequences starting with the % character are
       interpreted in the following way:

       %H
	   The name of the remote host (PAM_RHOST).

       %h
	   The name of the local host.

       %s
	   The service name (PAM_SERVICE).

       %t
	   The name of the controlling terminal (PAM_TTY).

       %U
	   The remote user name (PAM_RUSER).

       %u
	   The local user name (PAM_USER).

       All other sequences beginning with % expands to the characters following the % character.

OPTIONS

       file=/path/message
	   The content of the file /path/message will be printed with the PAM conversion function as PAM_TEXT_INFO.

MODULE TYPES PROVIDED

       All module types (auth, account, password and session) are provided.

RETURN VALUES

       PAM_BUF_ERR
	   Memory buffer error.

       PAM_SUCCESS
	   Message was successful printed.

       PAM_IGNORE
	   PAM_SILENT flag was given or message file does not exist, no message printed.

EXAMPLES

       For an example of the use of this module, we show how it may be used to print information about good passwords:

	   password optional pam_echo.so file=/usr/share/doc/good-password.txt
	   password required pam_unix.so
