Unfortunately duckdb doesn’t have an official package for OpenBSD so we need to compile it from source.
It turns out you can’t get extensions after compilation because there are no official packages for OpenBSD. So make sure to compile with the extensions you need.
Switch to a known release tag: git checkout tags/v1.1.2
pkg_add gmake cmake
git clone https://github.com/duckdb/duckdb.git
cd duckdb

SSH has had a history of vulnerabilities which could lead to remote code execution or compromise your server. Spiped protects against 0-day vulnerabilities. It prevents anyone without the key from even attempting to connect.
From the author:
Since data is authenticated before being forwarded to the target, this can allow you to SSH to a host while protecting you in the event that someone finds an exploitable bug in the SSH daemon — this serves the same purpose as port knocking or a firewall which restricts source IP addresses which can connect to SSH.> Spiped is a utility for creating encrypted and authenticated pipes between socket addresses. It’s like a force field for your SSH connection.
What is spiped?
Spiped is a utility for creating encrypted and authenticated pipes between socket addresses. It’s like a force field for your SSH connection.
Why use spiped?
Step 1: Install spiped
On Ubuntu or Debian:
sudo apt update
sudo apt install spiped
On CentOS or Fedora:
sudo yum install epel-release
sudo yum install spiped
Step 2: Generate a secret key
Spiped needs a shared secret key. Create one:
dd if=/dev/urandom bs=32 count=1 of=/etc/spiped-secret
chmod 600 /etc/spiped-secret
This creates a 32-byte random key and restricts access to root.
Step 3: Set up spiped on your VPS
Create a systemd service file:
sudo nano /etc/systemd/system/spiped-ssh.service
Paste this content:
[Unit]
Description=Spiped for SSH
After=network.target
[Service]
Type=simple
ExecStart=/usr/bin/spiped -d -s [0.0.0.0]:8022 -t [127.0.0.1]:22 -k /etc/spiped-secret
Restart=always
[Install]
WantedBy=multi-user.target
This tells spiped to:
Save and close the file.
Step 4: Start and enable the service
sudo systemctl start spiped-ssh
sudo systemctl enable spiped-ssh
Step 5: Configure your firewall
Allow incoming connections on port 8022:
For UFW:
sudo ufw allow 8022/tcp
For firewalld:
sudo firewall-cmd --add-port=8022/tcp --permanent
sudo firewall-cmd --reload
Step 6: Set up spiped on your local machine
Install spiped on your local machine using the same method as Step 1.
Create a script to start the local spiped instance:
nano ~/spiped-ssh-connect.sh
Add this content:
#!/bin/bash
spiped -e -s [127.0.0.1]:8022 -t [YOUR_VPS_IP]:8022 -k /path/to/spiped-secret
Replace [YOUR_VPS_IP]
with your VPS’s actual IP address.
Make the script executable:
chmod +x ~/spiped-ssh-connect.sh
Step 7: Connect to your VPS
Start the local spiped instance:
~/spiped-ssh-connect.sh
In a new terminal, connect via SSH:
ssh -p 8022 username@localhost
You’re now connected through an encrypted spiped tunnel!
Optional: Disable password authentication
For maximum security, use SSH keys and disable password authentication:
On your local machine, generate an SSH key pair:
ssh-keygen -t ed25519 -C "your_email@example.com"
Copy the public key to your VPS:
ssh-copy-id -p 8022 username@localhost
On your VPS, edit the SSH config:
sudo nano /etc/ssh/sshd_config
Set these options:
PasswordAuthentication no
PubkeyAuthentication yes
Restart the SSH service:
sudo systemctl restart ssh
Can’t connect? Check these:
Is spiped running on both machines?
sudo systemctl status spiped-ssh
Are you using the correct port (8022)?
Is your firewall allowing connections?
Did you copy the secret key to your local machine?
Are the IP addresses in your local script correct?
Spiped vs. VPN
Why use spiped instead of a VPN?
However, a VPN secures all traffic. Choose based on your needs.
You’ve now fortified your VPS’s SSH connection. Spiped adds a powerful layer of security, making life much harder for attackers.
Remember:
With these steps, you’ve significantly boosted your server’s security. Sleep easier knowing your VPS is better protected against SSH-based attacks.

or with www.
like www.yoursite.com
. One should redirect to the other and you should keep is consistent for SEO.
If you redirect naked to www.
, and you use Go, you can use the following Go middleware to have all naked requests redirect with 301 to www.
:
func RedirectNakedToWWW(handler http.Handler) http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
// if host doesn't have www. redirect
if !strings.HasPrefix(r.Host, "www.") {
http.Redirect(w, r, fmt.Sprintf("https://www.%s", r.Host)+r.URL.String(), http.StatusMovedPermanently)
return
}
handler.ServeHTTP(w, r)
})
}
