Grace à Techsys j'ai eu la chance d'assister à l'édition 2019 de PassTheSalt. C'est une conférence orientée sécurité informatique en locution anglaise par son caractère international. C'est la deuxième édition, elle se tient cette année encore à Polytech Lille. Chaque demi journée est regroupée par thème technique.

A brief history of configuration / @markburgess_osl

from vmsprawl to containersprawl
concern business value => adapt particulare case, tweaking like apt database
photo intéressante : bidonville vs la city => mutation improvement with chef : from configuration to timeplanning
mais ce qui manque le plus => les forêts !

## Tunnel SSH

Whoops, I forgot to create my dynamic tunnel on this SSH session. No problem, just press [enter] in the ssh session, then literally ~C to open the SSH options prompt (ssh>). You can then specify your tunnel option of -D 8022 or whatever and it will create it.
	#!/bin/bash
	# Source http://lzone.de/blog/Nagios+Check+for+Systemd+Failed+Units
	if [ -f /bin/systemctl ]; then
	failed=$(/bin/systemctl --failed --no-legend)
	failed=${failed/ */} # Strip everything after first space
	failed=${failed/.service/} # Strip .service suffix if [ "$failed" != "" ]; then
	echo "Failed units: $failed"
	exit 1
	else
	echo "No failed units."
