This blog helps you to get started with configuring sudo and learn how to avoid the most common mistakes. But the title “getting started with sudo” sounds a lot less interesting :-) Based on responses to my talks, one of the most popular configuration option of sudo is insults. You should not think about anything serious here: just some funny messages when a user mistypes a password. But as some users find these messages inappropriate, these are now disabled by default, but can be enabled.

... ➦The first sudo blog...
Let me tell you a personal story, how this blog was born.
First a bit of introduction. I am Peter Czanik, working for the past nine years as syslog-ng evangelist at Balabit. Obviously I also deal with the commercial variant, but my focus is Open Source. That is one of the reasons why I was very happy to learn that Todd Miller, developer of the sudo application, became my colleague when Balabit was acquired by One Identity last year.
