A rare beast.
Couldn’t resist, so I grabbed it for the collection.

Configuring WireGuard on CentOS, Debian, Ubuntu, and FreeBSD in four different ways

Below is a set of snippets for configuring WireGuard for three different Linux distributions and FreeBSD.
The setup assumes a Debian server with a 10.9.21.0/24 network.

Server, Debian

apt install wireguard-tools
nano /etc/network/interfaces.d/wg0

auto wg0
iface wg0 inet static
    address 10.9.21.1/32
    pre-up ip link add wg0 type wireguard
    pre-up wg setconf wg0 /etc/wireguard/wg0.conf
    up ip -4 route add 10.9.21.0/24 dev wg0
    # up /bin/systemctl restart sshd.service
    post-down ip link del wg0

umask 077
cd /etc/wireguard/
wg genkey > server-private.key
wg pubkey < server-private.key > server-public.key

nano /etc/wireguard/wg0.conf

[Interface]
ListenPort = 1234
PrivateKey = <server-private.key>

[Peer]
# Debian client
PublicKey = <public.key>
AllowedIPs = 10.9.21.3/32

The stock Keychron keycaps with the OSA profile look not bad, but I’m not a lover of typewriters aesthetic.
Since I’m used to hitting combos like CTRL/SUPER/ALT/SHIFT with a single finger for certain shortcuts, I needed to find low-profile keycaps that are all the same height.
Pressing two keys simultaneously may be unfamiliar to casual typists, but if you use a tiling WM, where everything from launching apps to window management - is shortcut-based, it makes total sense.
I immediately picked up some pretty decent low-profile Womier keycaps.
The undersides might have some mold marks, but with a little modding, they are actually quite good.
I also picked up some OUTEMU Half-height switches for testing.
They are low-profile, but that’s all.
The tactile feel is non-existent.
Looking ahead: the stock Keychron Silk POM Tactile Bananas are very good, but they honestly can’t be compared to the Gazzew Boba Black U4T.

We have a Deeper DP4H13S10 sonar, and the goal is to increase its signal range.
The original Deeper Range Extender costs about €195.
How can we solve this using what we already have? And even make it better?
It’s very simple.
