The aim of this project is to give some informations when you log into a server through SSH.

Warning This is Debian and Debian-related distributions only.
You need to install some packages:
apt-get install figlet lsb-release python-utmp bc
Optionnally, you can install
needrestart which is used to show a message if your server need a reboot (main reason (and the only one I know): you have upgraded your kernel).
If you don't install
needrestart, it will work, but you won't be warned about the need for a reboot.
needrestart warns you about services that need to be restarted too (but is slower than
checkrestart for that, see below).
You can optionnally install
debian-goodies which provides
checkrestart, which will be used to warn you about services that need to be restarted. Relying on
needrestart for that is slow (±7 seconds) while
checkrestart do it faster (less than one second).
NB: if you use Debian 11 Bullseye, install
python3-utmp instead of
python-utmp and change
sed -e "s/python/python3/" -i update-motd.d/20-system-info update-motd.d/sysinfo.py
cp -r update-motd.d/ /etc rm /etc/motd ln -s /var/run/motd /etc/motd
Disabling for some users
Just create a
/etc/update-motd.d/hushlogin file containing the names of the users, like:
You will find a working salt formula in
cd /srv/salt git clone https://framagit.org/luc/dynamic-motd.git motd salt your_server state.sls motd
