SYNOPSIS top 

       pam_echo.so [file=/path/message]

DESCRIPTION top 

       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 top
