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}
|
|

## 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
|
|

## 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
|
|

|
|
|
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
