syspatch(8) and /tmp sizing


On my new OpenBSD servers, I decided to use memory filesystem for /tmp. After looking at old servers usage, I decided that 64M of memory space would be enough. # grep mfs /etc/fstab swap /tmp mfs rw,nodev,nosuid,-s=64m 0 0 And that seemed well sized. Until I ran syspatch(8) and got a whole bunch of errors:

Running Arch Linux using OpenBSD vmd(8)


I had difficulties running Linux as a virtual machine using OpenBSD vmd(8). Ubuntu LTS crashed during installation wizard, Debian 9 does not seem to ship with virtio drivers, Alpine randomly freezes the console and Slackware … well slack has not been updated in years. Arch Linux seems to run well. And as I didn’t find a complete guide to install and run it using OpenBSD vmd(8), here are my notes.

Automated OpenBSD deployment on vmd(8)


Now that I have an OpenBSD server hosted in the Wild and capable of doing virtualization , I’ll migrate all my VM hosted on Synology Virtual Machine Manager. But even if the OpenBSD installer is straight forward, deploying tens of VM takes some time. So I set up an automated environment that provides fast and (nearly) finger-less deployment.

OpenBSD 6.5 with FDE on Online/Scaleway start-2-L/SuperMicro X11SSE-F


Online by Scaleway provides dedicated servers in France. The start-2-L reference is a “small” server that ships with KVM over IP. It is based on SuperMicro X11SSE-F . So far, the hardware seems to be supported pretty well and it is possible to run OpenBSD with Full Disk Encryption.

Automount Synology NFS shares from OpenBSD


A nice thing I like about macOS is that it automatically mounts CIFS shares from my Synology NAS. OpenBSD doesn’t seem to have any mounting utilities for SAMBA shares any more. But it can mount NFS shares. And those can be automatically mounted and unmounted using the amd(8) stock tool. So let’s configure the OpenBSD instances for automounting NFS shares.
