What is Resolvconf?
Resolvconf is a Linux utility that manages the Domain Name System (DNS) configuration for the Linux system. It is used to configure the DNS resolver with the required DNS servers and search domains. Resolvconf provides an easy way to manage the DNS configuration of a Linux system and is used by many Linux distributions.
How Resolvconf Works
When a Linux system needs to resolve a domain name to an IP address, it uses the Domain Name System (DNS) to perform the resolution. The DNS resolver requests the IP address of the domain name from the DNS servers configured in /etc/resolv.conf file. Resolvconf is used to manage the /etc/resolv.conf file and configure the DNS resolver with the required DNS servers and search domains.
Why Use Resolvconf with Wireguard?
Wireguard does not natively manage DNS settings. Therefore, to use the VPN, users need to ensure that their DNS settings are correctly configured. Resolvconf is an easy and efficient method for managing DNS settings on Linux systems, and it works well with Wireguard.
How to Configure Resolvconf with Wireguard?
To configure Resolvconf with Wireguard, you need to complete the following steps:
Step 1: Install Wireguard and Resolvconf
The first step is to ensure that both Wireguard and Resolvconf are installed on your Linux system. You can install both using the following commands:
sudo apt-get update sudo apt-get install wireguard resolvconf
Step 2: Generate the Wireguard Configuration
The next step is to generate the Wireguard configuration file. You can do this by running the following command:
umask 077 wg genkey | tee privatekey | wg pubkey > publickey
This command creates a private key and public key pair that will be used to encrypt the data transmitted over the VPN.
Step 3: Configure Wireguard
After generating the Wireguard configuration file, the next step is to configure Wireguard. You can create a configuration file by running the following command:
sudo nano /etc/wireguard/wg0.conf
Then, copy and paste the following configuration into the wg0.conf file:
[Interface] PrivateKey = (privatekey generated in step 2) Address = 10.0.0.1/24 ListenPort = 51820 [Peer] PublicKey = (publickey generated in step 2) AllowedIPs = 10.0.0.2/32 Endpoint = (public IP address of the remote server):51820
Make sure to replace the generated private key and public key with the output from step 2.
Step 4: Enable IP Forwarding
The next step is to enable IP forwarding on your system. You can do this by running the following command:
sudo sysctl -w net.ipv4.ip_forward=1
This command enables IP forwarding on your system, allowing packets to be forwarded between the VPN server and clients.
Step 5: Configure Resolvconf
The final step is to configure Resolvconf with the required DNS servers and search domains. You can do this by creating a new file called wg-resolv.conf in the /etc/resolvconf/resolv.conf.d/ directory. This file should contain the DNS servers that you want to use. For example:
nameserver 8.8.8.8 nameserver 8.8.4.4 search domain.com
Save and close the file when you’re done. Then, update Resolvconf by running the following command:
sudo resolvconf -u
