pam_issue - PAM module to add issue file to user prompt

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

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)

\n

machine's network node hostname (uname -n)

\o

domain name of this system

\r

release number of operating system (uname -r)

\t

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)

noesc

Turns off escape code parsing.

issue=issue-file-name

The file to output if not using the default.

Only the auth module type is provided.

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.

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

pam.conf(5), pam.d(5), pam(7)
