OpenBSD NFS Performance Tuning - Part 2

By Finde Labs |  Mar 15, 2019  | scripting, openbsd, tuning, nfs

Part two NFS performance tuning. I have some new data to publish. I reran the full NFS test, this time with the script transferring three files, with one sync and unmount in between the three transfers. I saw more interesting behavior that is worth noting, as well as publishing the script used to compile these logs.

Using Vultr Startup Scripts

By Finde Labs |  Feb 12, 2019  | openbsd, scripting, vultr

In a previous article, I wrote of my OpenBSD-Wireguard ansible configuration that I’ve been using for my personal VPN’s recently.

Using Vultr’s startup scripts in addition to the OpenBSD-Wireguard ansible playbook, one is able to deploy a wireguard VPN to any of Vultr’s datacenters within ten minutes. This includes the OS installation by Vultr, as well as the playbook execution following a final reboot.

OpenBSD with tmux

Being able to take off from work, and the next morning, be able to hop back into my tmux session from the day before is truly lifechanging. I used a custom screen config for a little while before stumbling across tmux. I read into tmux one day at work, and was simply amazed at how much easier it was to configure than screen! This led me to conduct an in-depth comparison between tmux and screen. Did you know, screen has some 254 known bugs? Some go back to 2005 the last time I checked.

Tmux is an active project that is significantly easier to configure, and just as stable in my experiance.

Using ifstated to watch an egress link

By Finde Labs |  Jan 19, 2019  | openbsd, ifstated, scripting

While developing my own OpenBSD router, I stumbled across a built-in service called ifstated. Previously, I was using a cronjob to run a script every five minutes to check the status of pppoe0. However, ifstated is able to do everything that my script could, in a more powerful way.

The inspiration for this configuration file originated heavily from calomel’s tutorial. I did modify a handful of items though, to better tailor it to my own router’s design.
