MOTD, issue.net and landscape-sysinfo
The command: landscape-sysinfo
The file: update-motd.d/50-landscape-sysinfo
landscape-sysinfo is a utility that displays information about the computer it is run on. This information is displayed upon login for console users (ssh and terminal login supported) and can also be seen at anytime by just calling landscape-sysinfo from the command line.
The /etc/issue and /etc/issue.net files are traditional text files used in older and POSIX-compliant systems.
The files /etc/issue, /etc/issue.net, and the update-motd.d system (e.g., 50-landscape-sysinfo) serve different purposes and reflect the evolution of how Linux systems display messages to users upon login or remote connection. The update-motd.d and Dynamic Message of the Day (MOTD) are part of a more dynamic system for MOTD generation
