Just ran across this interview with Wietse Venema in the Security Focus website.
“Wietse Venema started out as a physicist, but became interested in the security of the programs he wrote to control his physics experiments. He went on to create several well-known network and security tools, including the Security Administrator’s Tool for Analyzing Networks (SATAN) and The Coroner’s Toolkit with Dan Farmer. He is also the creator of the popular MTA Postfix and TCP Wrapper.”
I liked reading it, it gives some nice insight in the mind if the creator of Postfix. Hope you enjoy it as well.
