Stretch Messaggio del giorno

Versioni Compatibili Debian 9 "stretch"

Come rendere permanenti le modifiche a /etc/motd

Introduzione

Possiamo fare in modo che al momento del login via SSH o via terminale, Debian Stretch ci mostri alcune utili informazioni di sistema.
Per fare questo occorre installare alcuni pacchetti e modificare alcuni file.

Installazione

# install lsb-release 
apt-get install lsb-release

# install figlet to enable ASCII art
apt-get install figlet

# create directory
mkdir /etc/update-motd.d/

# change to new directory
cd /etc/update-motd.d/

# create dynamic files
touch 00-header && touch 10-sysinfo && touch 90-footer

# make files executable
chmod +x /etc/update-motd.d/*

# remove MOTD file
rm /etc/motd
