  \__ \  __/ |   \ V /  __/ |

Warning This Debian and Debian-related distributions only.

Dependencies

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).

Installation

cp -r update-motd.d/ /etc
rm /etc/motd
ln -s /var/run/motd /etc/motd

This is the for of ldidry/dynamic-motd

Diffrence :

  • Remove salt
  • Add some cache to avoid a connection stuck during 30 secondes
