Manual Pages  — PAM_ECHO


pam_echo – Echo PAM module



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


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:
  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.conf(5), pam(8)


The pam_echo module and this manual page were developed for the FreeBSD Project by ThinkSec AS and NAI Labs, the Security Research Division of Network Associates, Inc. under DARPA/SPAWAR contract N66001-01-C-8035 ("CBOSS"), as part of the DARPA CHATS research program.
