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

mingetty - minimal getty for consoles
SYNOPSIS
mingetty [--noclear] [--nonewline] [--noissue] [--nohangup] [--nohostname] [--long-hostname] [--loginprog=/bin/login] [--nice=10]
[--delay=5] [--chdir=/home] [--chroot=/chroot] [--autologin username] [--loginpause] tty
DESCRIPTION
mingetty is a minimal getty for use on virtual consoles. Unlike agetty(8), mingetty is not suitable for serial lines. I recommend using
mgetty(8) for this purpose.
OPTIONS --noclear
Do not clear the screen before prompting for the login name (the screen is normally cleared).
--nonewline
Do not print a newline before writing out /etc/issue.
--noissue
Do not output /etc/issue.
--nohangup
Do not call vhangup() to disable writing to this tty by other applications.
--nohostname
Do not print the hostname before the login prompt.
--long-hostname
By default the hostname is only printed until the first dot. With this option enabled, the full text from gethostname() is shown.
--loginprog /bin/login
Change the login app.
--nice 10
Change the priority by calling nice().
--delay 5
Sleep this many seconds after startup of mingetty.
--chdir /home
Change into this directory before calling the login prog.
--chroot /chroot
Call chroot() with this directory name.
--autologin username
Log the specified user automatically in without asking for a login name and password. Check the -f option from /bin/login for this.
--loginpause
Wait for any key before dropping to the login prompt. Can be combined with --autologin to save memory by lazily spawning shells.
ISSUE ESCAPES
mingetty recognizes the following escapes sequences which might be embedded in the /etc/issue file:
d insert current day (localtime),
l insert line on which mingetty is running,
m inserts machine architecture (uname -m),
inserts machine's network node hostname (uname -n),
o inserts domain name,
inserts operating system release (uname -r),
insert current time (localtime),
s inserts operating system name,
u resp. U the current number of users which are currently logged in. U inserts "n users", where as u only inserts "n".
v inserts operating system version (uname -v).
EXAMPLE
"Linux eos i386 #1 Tue Mar 19 21:54:09 MET 1996" was produced by putting "s
m v" into /etc/issue.
FILES
/etc/issue, /var/run/utmp.
