man pam_issue (8): 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:

: current day

: name of this tty

: machine architecture (uname -m)

: machine's network node hostname (uname -n)

: domain name of this system

: release number of operating system (uname -r)

: current time

: operating system name (uname -s)

: number of users currently logged in

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

: 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
