Wireguard all the things.

The good thing about wireguard besides its security is that it keeps things very simple plus OpenBSD simplicity makes the whole environment easy to setup even with crossing platform, such us iOS, Android, Windows, Linux and so on. For this setup you need only "libqrencode" and "wireguard-tools" to create qr codes to import the vpn configuration on your devices, so for this we do...

The complete idiot's guide to OpenBSD on the Pinebook Pro.

Today I will show you how I installed the latest snapshot of OpenBSD on my Pinebook Pro with plenty of detail so that you can do it, too. I will include instructions for setting up full disk encryption, and conclude with a summary of my experience running OpenBSD on this device...

A reckless guide to OpenBSD.

Welcome to a new weekly series of articles for intermediate to advanced level users of OpenBSD, focusing on aspects of using and customising the system that are not broadly covered or encouraged by the project's own official documentation, (hence the term ‘reckless guide’)...

Native IPv6 with OpenBSD and Aussie Broadband

We are coming on two decades since IPv6 became a recognised standard and generally available but it is still not being widely adopted by people and organisations that have easy access to IPv4 address space. Even if you have a native IPv4 address, it will typically be in the form of some CG-NAT or other NAT on your customer premises equipment (CPE)...

Heap Overflow in OpenBSD's slaacd via Router Advertisement

In this blog post we analyze a heap overflow vulnerability we discovered in the IPv6 stack of OpenBSD, more specifically in its slaacd daemon. This issue, whose root cause can be found in the mishandling of Router Advertisement messages containing a DNSSL option with a malformed domain label, was patched by OpenBSD on March 21, 2022. A proof-of-concept to reproduce the vulnerability is provided.

How to talk to a local IPMI under OpenBSD.

Much like Linux, modern versions of OpenBSD are theoretically able to talk to a suitable local IPMI using the standard ipmi(4) kernel driver. This is imprecise although widely understood terminology; in more precise terms, OpenBSD can talk to a machine's BMC (Baseboard Management Controller) that implements the IPMI specification using one of a number of standard interfaces, as covered in the "System Interfaces" section of ipmi(4). However, OpenBSD throws us a curve ball in that the ipmi(4) driver is normally present in the default OpenBSD kernel but not enabled...
