These are random notes -- more or less about OpenBSD. Some may
not fit here well, but they could relate to OpenBSD or similar
operating systems in some way...
## Get some filesystem information
```console
$ dumpfs /dev/rsd1a
magic 19540119 (FFS2) time Thu Nov 16 21:14:34 2023
[...] (snip; lots of output...)
```
This can be helpful if you want to know, which filesystem you actually
use on your OpenBSD box.
## Python
### ModuleNotFoundError
Install python modules with pip.
~~~console
$ python3 -m pip install --user --upgrade ${example_module}
~~~
## Git
## Cloudlog (server)
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
sending incremental file list
created directory etc/ssl
./
cert.pem
ikeca.cnf

x509v3.cnf

$ doas rcctl restart php80_fpm
php80_fpm(ok)
php80_fpm(ok)
~~~
## Cloudlog (client)
Use of the online logging tool Cloudlog on my OpenBSD machine.
First off, connect the TX-500 with the computer (CAT cable) and
start `rigctld`:
```console
$ rigctld -m 2014 -r /dev/cuaU0 -s 9600 -v
```
I use `2014` which is actually a Kenwood TS-2000 -- but on OpenBSD hamlib is currently
at version 4.4 and the TX-500 is only available on
[version ≥4.5](https://github.com/Hamlib/Hamlib/blob/master/NEWS#L199).
For newer hamlib versions (≥4.5) use the rig 2050 like:
```console
$ rigctld -m 2050 -r /dev/cuaU0 -s 9600 -v
```
In combination with Digirig I would probably use something like this,
because otherwise Digirig would instantly key the transceiver:
```console
$ rigctld -m 2014 -r /dev/cuaU0 -s 9600 --set-conf=rts_state=OFF -v
```
Well, I tested this on my desk at home but never used my Laptop for
doing digital modes with my TX-500 though -- but I want this to be noted
here just in case I should need it someday.
On another terminal start [`cloudlogbashcat.sh`](https://github.com/g0wfv/CloudlogBashCat):
```console
$ cloudlogbashcat.sh
```
Now, if you open the website of your Cloudlog installation (and if you have
setup your rigs) and select the radio that uses cloudlogbashcat.
## Z-Shell
### Where is this alias defined?
I defined an alias `ls` but I forgot where it was.
~~~console
$ PS4='+%x:%I>' zsh -i -x -c '' |& grep ls
~~~
There will be a lot of screen output probably.
### Renaming multiple directories
~~~console
$ count=1; zmv -n '*' '$f[1,4]/$((count++))-$f[12,-1]'
mv -- 2023-08-05-problems-with-apt-keys-on-my-hotspots 2023/51-problems-with-apt-keys-on-my-hotspots
mv -- 2023-08-26-dmrhost-on-a-raspberrypi4-with-openbsd-or-freebsd 2023/52-dmrhost-on-a-raspberrypi4-with-openbsd-or-freebsd
mv -- 2023-09-16-openbsd-current-built-from-source 2023/53-openbsd-current-built-from-source
~~~
Moves subdirectories into other folder structure with a counting variable.
~~~console
$ count=16; zmv -Q '*(/)' '$((count++))-$f[12,-1]'
mv -- 2021-08-08-win10-grub2-and-uefi 16-win10-grub2-and-uefi
mv -- 2021-08-12-running-n1mm-logger-on-linux 17-running-n1mm-logger-on-linux
mv -- 2021-10-03-winlink-and-vara-on-linux 18-winlink-and-vara-on-linux
mv -- 2021-10-03-wordlist-generation 19-wordlist-generation
mv -- 2021-10-26-processes-accessing-mountpoints 20-processes-accessing-mountpoints
~~~
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
mv -- 29-using-nfs-on-a-raspberry-pi 28-using-nfs-on-a-raspberry-pi
mv -- 30-vpn-tunnel-into-hamnet-on-fedora-36 29-vpn-tunnel-into-hamnet-on-fedora-36
mv -- 31-winlink-on-linux-fix-invalid-handle-on-logfiles 30-winlink-on-linux-fix-invalid-handle-on-logfiles
mv -- 32-hamnet-on-the-pfsense 31-hamnet-on-the-pfsense
mv -- 33-changing-network-metrics-on-linux 32-changing-network-metrics-on-linux
mv -- 34-change-git-submodule-url 33-change-git-submodule-url
~~~
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-*' '*'
mv -- 59-pat-winlink-on-openbsd pat-winlink-on-openbsd
~~~
