These are my notes that I want to summarize about the OpenBSD
operating system. 

## Get some filesystem information

```console
$ dumpfs /dev/rsd1a
magic	19540119 (FFS2)	time	Thu Nov 16 21:14:34 2023
[...] (snip; lots of output...)

## Python

### ModuleNotFoundError

I recently tried to look at CHIRP, a tool to program (amateur) radios.
But at its start I only got an error:

~~~console
$ chirp

Most of these kind of errors look like this and it's quite clear: we need to install
a package called yattag -- more precisely it is a python module.

I do install python modules this way:

~~~console
$ python3 -m pip install --user --upgrade yattag

## Cloudlog

Cloudlog is a webapplication written in PHP that allows ham radio amateurs
to log contacts online. I host my own instance on my server and I finally
looked into why I never got satellites shown in <kbd>SAT Timers</kbd>.

I use php-fpm and it is running as the user `www`. It is kind of jailed and it
cannot read `/etc/ssl/cert.pem` -- so the https connections cannot be verified
and it failes at downloading the satellites infos from other websites.

I solved this by copying `/etc/ssl` to `/var/www/etc/ssl` via rsync, keeping file
permissions intact. I may setup a cronjob for this maybe.

~~~console
$ doas cp -r /etc/ssl etc/ssl
$ doas rcctl restart php80_fpm
~~~

## Apache (Server)

As I host my own Cloudlog instance on my server I run into problems sometimes.
The SAT and Hams.at tools never worked for me and I looked into this today. I
got some weird SSL related errors and I thought first it was a misconfiguration
in my `php.ini` file but it finally turned out, that `ServerRoot` in my Apache
configuration pointed to `/var/www` and Cloudlog wasn't able to read the main
CA file from `/etc/ssl/cert.pem`. I copied `/etc/ssl` to `/var/www/etc/ssl` and
it works just fine -- now I need a solution to update these certs when the OS
updates the files in `/etc/ssl` because a symlink did not work for this.

tl;dr;

~~~console
$ doas rsync -avhzrp /etc/ssl/ etc/ssl
