PAM_ISSUE(8)							 Linux-PAM Manual						      PAM_ISSUE(8)

NAME

       pam_issue - PAM module to add issue file to user prompt

SYNOPSIS

       pam_issue.so [noesc] [issue=issue-file-name]

DESCRIPTION

       pam_issue is a PAM module to prepend an issue file to the username prompt. It also by default parses escape codes in the issue file similar
       to some common getty's (using x format).

       Recognized escapes:

       d
	   current day

       l
	   name of this tty

       m
	   machine architecture (uname -m)

       

	   machine's network node hostname (uname -n)

       o
	   domain name of this system

       
	   release number of operating system (uname -r)

       	
	   current time

       s
	   operating system name (uname -s)

       u
	   number of users currently logged in

       U
	   same as u except it is suffixed with "user" or "users" (eg. "1 user" or "10 users")

       v
	   operating system version and build date (uname -v)

OPTIONS

       noesc
	   Turns off escape code parsing.

       issue=issue-file-name
	   The file to output if not using the default.

MODULE TYPES PROVIDED

       Only the auth module type is provided.

RETURN VALUES

       PAM_BUF_ERR
	   Memory buffer error.

       PAM_IGNORE
	   The prompt was already changed.

       PAM_SERVICE_ERR
	   A service module error occurred.

       PAM_SUCCESS
	   The new prompt was set successfully.

EXAMPLES

       Add the following line to /etc/pam.d/login to set the user specific issue at login:

		   auth optional pam_issue.so issue=/etc/issue
