The previous tip was about change the banner after login. This tip, however, was to change the banner of the login prompt aka pre-login message.
The file to change is /etc/issue. It also support escape codes to display some additional info :
b = Insert the baudrate of the current line. d = Insert the current date. s = Insert the system name, the name of the operating system. l = Insert the name of the current tty line. m = Insert the architecture identifier of the machine, eg. i486 n = Insert the nodename of the machine, also known as the hostname. o = Insert the NIS domainname of the machine. O = Insert the DNS domainname of the machine. r = Insert the release number of the OS, eg. 1.1.9. t = Insert the current time. u = Insert the number of current users logged in. U = Insert the string “1 user” or “<n> users” where <n> is the number of users login.
Adiós !!!
