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

operating system.

### 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
|
|

ModuleNotFoundError: No module named 'yattag'

|
|
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
|
|
$ cd /var/www
|
|
$ doas rsync -avhzrp /etc/ssl/ etc/ssl
|
|

That was the second part, counting from where we stopped from the previous directory.
|
|
|
|
There was a draft post left in `2022` which I deleted, now I had to renumber the folders
|
|
from `28-*` to `34-` to a number lower by 1.
|
|
|
|
~~~console
|
|
$ for i in {29..34}; do zmv -n -W $i'*' $((--i))'*'; done

So, there is still one post left that is actually a draft post and I'd like to
|
|
remove the leading number from that directory.
|
|
|
|
~~~console
|
|
$ zmv -n -W '59-*' '*'
