Iodine is a tool that allows you to tunnel IPv4 data through a DNS server. This can be useful in situations where you need to access the Internet from a restrictive network, such as a public Wi-Fi hotspot or a business network that blocks certain applications. In this tutorial, we will guide you through the steps required to install iodine on Debian Latest.
Before starting, make sure you have the following:
The first thing you need to do is update your system. This ensures that you have the latest security patches and software updates.
sudo apt-get update
sudo apt-get upgrade
Iodine requires the libraries libssl-dev and libcap-dev. You can install them using the following command:
sudo apt-get install libssl-dev libcap-dev
You can download iodine from the official website using the following command:
curl -O https://code.kryo.se/iodine/iodine-0.7.0.tar.gz
Next, extract the archive:
tar -xzvf iodine-0.7.0.tar.gz
Go to the extracted directory:
cd iodine-0.7.0
Compile and install iodine:
make
sudo make install
Now that iodine is installed, you need to configure it. First, you need to create a password file. You can do this using the following command:
sudo sh -c 'echo "password" > /etc/iodine/password.txt'
sudo chmod 600 /etc/iodine/password.txt
Replace "password" with a strong password of your choice.
Next, you need to modify the /etc/default/iodine file. Open it using a text editor:
sudo nano /etc/default/iodine
Add the following lines:
IODINE_USER=tunnel
IODINE_DEVICE=tun0
IODINE_IP=192.168.1.1
IODINE_PASSWORD_FILE=/etc/iodine/password.txt
IODINE_DNS_IP=8.8.8.8
Save the file and exit the text editor.
Finally, you can start iodine using the following command:
sudo service iodine start
You can verify that iodine is running by checking the system log:
sudo tail -f /var/log/syslog
In this tutorial, we guided you through the steps required to install iodine on Debian Latest. Now that iodine is installed and configured, you can use it to tunnel IPv4 data through a DNS server.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
