Despite the usual connection to a remote hosts, SSH can be used in several other cases. In this blog, I will present 3: proxy, tunnel and JumpServer.

I've build a DNS server which allow me to skip ads, and all those not funny informations. All devises use it as DNS profit from this functionality, mobiles, laptops, ... This feature is so addictive, that when I must replace his hardware, we can feel how it's annoying to not have it.

I'm sharing here some practices I'm following and some small tips/tools which facilitate my usage of OpenBSD in my day to day. Some a really specific to my usage, others could be re-used.

You have just upgraded your OpenBSD machine to the brand new release, but some of your applications are no more working because they do not have the required python package. This is a very common problem between python package you have installed via pkg_add and the one you have installed via "pip install". The problem is that both are installed on your machine in /usr/local/lib/python3.8/site-packages. I propose you a methodology to identify which one were installed with which tool

Since OpenBSD 6.8, boot process does not work on my ASRock J5005-ITX board. The root cause is the kernel size. In this blog, I present you 2 possible solutions

On one of my OpenBSD machine, I had, after several months of usage, a full /tmp filesystem. Despite by checking files, none were big enough to take full space of /tmp. Why [df](https://man.opensd.org/df) shows a full filesystem ? and why no big files identified by [ls](https://man.openbsd.org/ls), neither by [du](https://man.openbsd.org/du) ?
