Like the Spanish Inquisition, nobody expected the internet. Its earliest appearance (as ARPANET) took place in the same year—1969—as the comedy troupe behind the Spanish Inquisition quip, Monty Python. But during its first decade, the internet was treated as a convenience for file-sharing and a couple other applications; few observers anticipated how it would alter modern life until decades later. The major institution that brought computers into the internet age was the University of California at Berkeley, which created a version of Unix that they called the Berkeley Software Distribution and is now known as BSD.

OpenBSD's sppp_pap_input function used attacker-controlled length fields as the bcmp comparison length for credential validation. Sending zero-length name and password fields caused bcmp to return 0 unconditionally, bypassing PAP authentication entirely. The vulnerability was introduced in 1999 and survived for 27 years before being fixed.

The NetBSD Foundation’s 2026 AGM covers progress on NetBSD 11.0 (now at RC5), the CVS-to-Git/Mercurial migration, and infrastructure challenges like LLM scraping and hardware aging. Highlights include five Google Summer of Code projects, CNA onboarding for security advisories, and plans to streamline release cycles. The full IRC log details team updates from core, admins, releng, and security.

System administrators must manage software packages. With a mix of Unix-family operating systems, you must use the commands specific to each platform. On Red-Hat-derived systems, these include rpm, dnf (formerly yum), and urpmi. On Debian derivatives such as the many Ubuntu variants, these include apt and dpkg. On FreeBSD, one command pkg does it all. On OpenBSD, it's a family of commands starting pkg_, and on Solaris, similarly named pkg. Here are explanations through examples of how to manage software packages and answer questions about installed or missing software using these commands across all those operating systems.

Traduction de l'article EN → FR 'OpenSMTPD Is The Mail Server For The Future' décrivant la bascule d'exim vers OpenSMTPD définitive dans OpenBSD, depuis la v7.9 — article de Peter N.M. Hansteen

The SMTP mail server for the 21st century and onwards is OpenSMTPD, which is developed as an integral part of OpenBSD, but available in a portable variety too.

It was one of those things that I had fully intended to do years ago, but I only got around to actually doing once there was a definite deadline to get it done.

The time has come, as OpenBSD 7.9 will leave the exim package behind, and exim users will need to find a replacement before upgrading. This article describes my transition to OpenBSD's own OpenSMTPD mail server.

Network-oriented readers will be familiar with the concept of overload tables, commonly used with state tracking options to create adaptive rulesets for such things as punishing password-guessing botnets. A downside to tables that would tend to fill up indefinitely is that at some point they will be quite full, and the administrator would need to either manually run pfctl expire or set up a crontab entry to weed out old entries at intervals.
