WireGuard Guide for Ubuntu

🔒 WireGuard Complete Guide

Ubuntu Server Setup & Configuration

1 🔄 Update System

Always start by updating your system packages to ensure you have the latest security patches and dependencies:

sudo apt update && sudo apt upgrade -y

💡 Tip: The -y flag automatically confirms the upgrade prompt. Remove it if you want to review packages before upgrading.

2 📦 Install WireGuard

Install WireGuard and required tools:

sudo apt install wireguard wireguard-tools -y

For Ubuntu 18.04 and earlier, you may need to add the PPA first:

sudo add-apt-repository ppa:wireguard/wireguard sudo apt update sudo apt install wireguard wireguard-tools -y

3 🔑 Generate Keys

Generate private and public key pairs:

wg genkey | sudo tee /etc/wireguard/private.key sudo chmod 600 /etc/wireguard/private.key sudo cat /etc/wireguard/private.key | wg pubkey | sudo tee /etc/wireguard/public.key

⚠️ Security Note: Keep your private key secure! The chmod 600 command ensures only root can read the private key.

4 ⚙️ Configure WireGuard

Create and edit the WireGuard configuration file:

sudo nano /etc/wireguard/wg0.conf

Add the following configuration (example for server):

[Interface] # Server configuration PrivateKey = <your_server_private_key> Address = 10.8.0.1/24 ListenPort = 51820 SaveConfig = true # Enable IP forwarding (for server/gateway setups) PostUp = echo 1 > /proc/sys/net/ipv4/ip_forward PostUp = iptables -A FORWARD -i wg0 -j ACCEPT PostUp = iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE PostDown = iptables -D FORWARD -i wg0 -j ACCEPT PostDown = iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE [Peer] # Client 1 PublicKey = <client_1_public_key> AllowedIPs = 10.8.0.2/32 # Optional: PresharedKey for additional security # PresharedKey = <preshared_key> [Peer] # Client 2 PublicKey = <client_2_public_key> AllowedIPs = 10.8.0.3/32

📝 Configuration Notes:

• Address: The VPN IP address for this interface
• ListenPort: UDP port WireGuard listens on (default: 51820)
• SaveConfig: Automatically save runtime configuration
• AllowedIPs: IP ranges that can be routed through this peer

5 🌐 Enable IP Forwarding (Server Only)

For server/gateway setups, permanently enable IP forwarding:

sudo nano /etc/sysctl.conf

Uncomment or add this line:

net.ipv4.ip_forward=1

Apply the changes:

sudo sysctl -p

6 🎮 Manage WireGuard

Start WireGuard:

sudo wg-quick up wg0

Stop WireGuard:

sudo wg-quick down wg0

Enable on Boot:

sudo systemctl enable wg-quick@wg0

Disable Autostart:

sudo systemctl disable wg-quick@wg0

Check Status:

sudo systemctl status wg-quick@wg0

sudo wg show

Restart After Config Changes:

sudo wg-quick down wg0 && sudo wg-quick up wg0

7 🔥 Configure Firewall

If using UFW (Ubuntu's default firewall), allow WireGuard port:

sudo ufw allow 51820/udp

Allow forwarding (if acting as server):

sudo nano /etc/ufw/before.rules

Add these lines at the beginning (after the header comments):

# NAT table rules *nat :POSTROUTING ACCEPT [0:0] -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE COMMIT

Also edit UFW's sysctl settings:

sudo nano /etc/ufw/sysctl.conf

Ensure this line is uncommented:

net/ipv4/ip_forward=1

Reload UFW:

sudo ufw reload

🔧 Troubleshooting

Check Logs:

sudo journalctl -xe | grep wireguard

Verify Interface:

ip a show wg0

Test Connectivity:

ping 10.8.0.1

Check Active Connections:

sudo wg show wg0 latest-handshakes

✅ Quick Command Reference

🚀 Start/Stop

wg-quick up wg0
wg-quick down wg0

💾 Auto-start

systemctl enable wg-quick@wg0
systemctl disable wg-quick@wg0

📊 Monitor

wg show
systemctl status wg-quick@wg0

⚙️ Configure

nano /etc/wireguard/wg0.conf
wg-quick down wg0 && wg-quick up wg0

🎉 Setup Complete! Your WireGuard VPN is now configured. Remember to:

• Keep your private keys secure
• Regularly update your system
• Monitor connection logs for unusual activity
• Document your peer configurations

 Model data; chrome://on-device-internals/

 

Step 1: Force Download via Components Page

This is the most reliable method:

1. Go to: chrome://components/
2. Find: "Optimization Guide On Device Model"
3. Click: "Check for update" button
4. Wait for it to download (you'll see the version number update)
5.  

 

3. Monitor the download:
   • Open a new tab: chrome://on-device-internals
   • Go to the "Model Status" tab
   • You should see Gemini Nano downloading
4. Wait 5-15 minutes for download to complete
5. Verify it's ready:

await LanguageModel.availability();  // Should return 'available'

 

const session = await LanguageModel.create({ outputLanguage: 'lt' });
const result = await session.prompt('Parasyk haiku apie kodavimą');
console.log(result);
