Quickly add git version tags for specified chef cookbook (could easily be adapted to any other piece of infrastructure, eg. npm package.json file, as long as one is able to extract unique version identifier on specified git ref)

stunnel transparent proxy (server) on localhost. use transparent=source; connect=127.1.1.1:... in stunnel configuration (mostly borrowed from sslh documentation)
View stunnel-transparent.sh

# destination

# DROP martian packets as they would have been if route_localnet was zero
