We’ve put together this guide to help you learn everything you need to know about turn server on Debian, so let’s get started!
📝 What is a Turn Server?
Before we get into the specifics of setting up a turn server on Debian, let’s first define what a turn server is. A turn server is a piece of software that relays network traffic between hosts. It can be used to bypass firewalls, NATs, and other network obstacles that might otherwise prevent direct communication between hosts.
In other words, a turn server can be used to establish a secure and reliable connection between hosts that would otherwise be unable to communicate directly.
🔍 How Does a Turn Server Work?
A turn server works by acting as an intermediary between two hosts that are unable to communicate directly. When one host sends a message to the other, the turn server receives the message and relays it to the other host. This allows the two hosts to communicate with each other, even if they are behind firewalls or NATs.
The turn server uses a protocol called Session Traversal Utilities for NAT (STUN) to determine the IP address and port number of each host. It then uses a protocol called Traversal Using Relays around NAT (TURN) to relay messages between the hosts.
🔧 Setting up a Turn Server on Debian
Now that we’ve covered the basics of what a turn server is and how it works, let’s get into the nitty-gritty of setting one up on Debian. Here’s a step-by-step guide to help you get started:
Step |
Description |
|---|---|
1 |
Install Coturn on your Debian server. |
2 |
Configure Coturn by editing the /etc/turnserver.conf file. |
3 |
Start the Coturn service using the systemctl command. |
4 |
Configure your client to use the newly created turn server. |
5 |
Test your connection to ensure that everything is working correctly. |
And that’s it! Of course, there are many more nuances to setting up a turn server on Debian, but these five steps should give you a general idea of what’s involved.
👍 Advantages of Using a Turn Server
Now that we’ve covered how to set up a turn server, let’s take a look at some of the advantages of using one:
1. Secure Connections
A turn server can be used to establish secure connections between hosts, even if they are behind firewalls or NATs. This is especially important for sensitive information, such as financial data or personal information.
2. Reliable Communication
Since a turn server relays messages between hosts, it ensures that communication is reliable. Even if one host is experiencing network issues, the turn server can help to maintain a stable connection.
3. Bypassing Firewalls and NATs
A turn server can help to bypass firewalls and NATs, which can otherwise prevent direct communication between hosts. This makes it an ideal solution for remote workers who need to access company resources.
👎 Disadvantages of Using a Turn Server
While turn servers offer many advantages, there are also some potential disadvantages to consider:
1. Increased Latency
Since a turn server relays messages between hosts, it can introduce some latency into the communication. This can be especially noticeable in real-time applications like video conferencing.
2. Increased Bandwidth Usage
A turn server can also increase bandwidth usage, since it relays messages between hosts. This can be a concern for organizations with limited bandwidth.
3. Configuration Complexity
Setting up and configuring a turn server can be a complex process, especially for those who are new to networking. This can be a barrier to adoption for some organizations.

🤔 Frequently Asked Questions
1. What is a turn server used for?
A turn server is used to relay network traffic between hosts that are unable to communicate directly. It can be used to bypass firewalls, NATs, and other network obstacles.
2. How do I set up a turn server on Debian?
Setting up a turn server on Debian involves installing the Coturn software, configuring it, starting the service, and configuring your client to use the turn server. For more detailed instructions, please see the section above.
3. What are the advantages of using a turn server?
The advantages of using a turn server include secure connections, reliable communication, and the ability to bypass firewalls and NATs.
4. What are the disadvantages of using a turn server?
The disadvantages of using a turn server include increased latency, increased bandwidth usage, and configuration complexity.
5. Can I use a turn server with any operating system?
Yes, turn servers can be used with any operating system. However, the specific installation and configuration process may differ depending on the operating system in question.
6. Does a turn server use a lot of resources?
A turn server can use a significant amount of CPU and memory resources, especially if it is relaying a large amount of traffic. However, this can be mitigated by optimizing the configuration and hardware used.
7. Is a turn server necessary for all applications?
No, a turn server is not necessary for all applications. However, it can be a valuable tool for establishing secure and reliable communication between hosts that would otherwise be unable to communicate directly.
8. What is the difference between a turn server and a STUN server?
A turn server is used to relay messages between hosts that are unable to communicate directly, while a STUN server is used to determine the IP address and port number of a host. Both servers use the STUN protocol to communicate.
9. Can I run multiple turn servers on the same network?
Yes, you can run multiple turn servers on the same network. However, it’s important to ensure that they are properly configured and not conflicting with each other.
10. Can I use a turn server with IPv6?
Yes, turn servers can be used with IPv6. However, the specific configuration may differ depending on the turn server software in use.
11. Can I use a turn server with WebRTC?
Yes, turn servers can be used with WebRTC to establish secure and reliable communication between hosts that are unable to communicate directly.
12. How do I test if my turn server is working correctly?
You can test your turn server by establishing a connection between two hosts and monitoring the traffic between them. There are also many testing tools available online that can help you verify that your turn server is working correctly.
13. What is the cost of using a turn server?
The cost of using a turn server depends on a variety of factors, including the specific turn server software in use, the amount of traffic being relayed, and the hardware used to run the server. However, there are many free and open source turn server solutions available.
