Why WireGuard for Manjaro?
WireGuard System Requirements
| Requirement | Details |
|---|---|
| Kernel Version | 5.6 or higher |
| Disk Space | Minimal; less than 1 MB |
| CPU | Any modern CPU |
| RAM | At least 256 MB |
Other Requirements
You’ll also need configuration files from your VPN provider. These are the settings that tell WireGuard how to connect to your VPN service. No install needed here; just a simple download from your provider’s website.
Preparations Before Installing WireGuard
WireGuard doesn’t come pre-configured for any specific VPN service. Thus, make sure to jot down your service provider’s public keys, DNS, and endpoint details. You’ll need them.
Proceed to update your system, and make sure the supporting tools are updated (WireGuard has been integrated into the Linux kernel since 5.6). We’re also going to enable it to start by default using systemctl.
pamac update
pamac install wireguard-tools
systemctl enable wg-quick@wg0
Installing WireGuard
After installing the tools, it’s time to place your configuration files. These usually come from your VPN provider and go into the /etc/wireguard/ directory. Make sure to name it something memorable like wg0.conf.
sudo cp Downloads/WolfWireGuard-US-FREE-313016.conf /etc/wireguard/wg0.conf
Additional Considerations
Also, keep an eye on your firewall settings. WireGuard operates over UDP, so make sure to allow it in your firewall rules.
Configuring WireGuard on Manjaro
Best Practices for WireGuard Scripts
Scripts are your best friend when it comes to automating configurations. For DNS resolution, you’ll want to use resolvconf or systemd-resolved. Here’s a sample script to set up DNS:
echo "nameserver 8.8.8.8" | sudo resolvconf -a tun.%i -m 0 -x[Picture Prompt]: A screenshot of a terminal window showing the above script being executed.
IP Routes
Routing is crucial. Use the ip command to set up routes. For example, to route all traffic through the VPN:
sudo ip route add 0.0.0.0/0 dev wg0Customizing Settings
You can edit the WireGuard configuration file located at /etc/wireguard/wg0.conf to customize settings. Use a text editor like nano:
sudo nano /etc/wireguard/wg0.confOptimizing WireGuard
To optimize, consider using the PersistentKeepalive option in your configuration file. This is especially useful if you’re behind a NAT.
Using WireGuard on Manjaro
Simply run:
sudo wg-quick up wg0
Confirming Traffic Routing
To confirm that your traffic is being routed through WireGuard, you can use the wg command:
sudo wg show wg0This will display the latest handshake, confirming that data is being transferred.
Troubleshooting WireGuard
| Scenario | Probable Cause | Solution | Command |
|---|---|---|---|
| WireGuard service won’t start | Incorrect configuration file | Validate the configuration file for syntax errors. | sudo wg-quick up [config-file] |
| Connection established but no internet | DNS resolution issue | Edit the WireGuard configuration to use a reliable DNS. | sudo nano /etc/wireguard/wg0.conf |
| Slow connection speed | Server overload or distance | Switch to a closer or less crowded WireGuard server. | sudo wg set wg0 peer [peer] endpoint [new-server]:[port] |
| Frequent disconnections | Unstable network | Test your network stability. If the issue persists, try another WireGuard server. | ping -c 4 [server-ip] |
| Cannot access local network resources | Incorrect AllowedIPs setting | Modify the AllowedIPs in your WireGuard configuration to include your local network range. | sudo nano /etc/wireguard/wg0.conf |
