]
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.
- 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
