Creating And Running DNS Apps On Technitium DNS Server

Technitium DNS Server version 6.0 has just been released with a new shiny feature called DNS Apps that allows you to build and run custom applications on your DNS server. Just like how a web application runs on a web server, think of a DNS application running on a DNS Server. This makes the DNS server more powerful allowing you to run custom apps based on your own business logic.

Technitium DNS Server v6

DNS Apps

The DNS applications are written in .NET as a class library project. The compiled DLL file with its references are then zipped and installed on the DNS server as an App. There are ready to use apps available in the DNS App Store to install from the DNS Server web console. The source code too is available on GitHub which can be forked and modified as required.

Technitium DNS Server With The Default DNS App Installed

APP Record

To use these apps you need to add the proprietary APP record to your primary zone. The APP record specifies the name of the installed app, the class path that handles the requests, and custom record data if any. When the DNS server received a request that hits the APP record, the request is then handed over to the installed DNS app as specified by the APP record. From here, the DNS App is responsible to generate a valid response to the DNS request. This entire process will look quite simple once you try to configure the APP record.

The APP Record Configuration

You can have an APP record per sub domain name and one APP record for the zone apex. If a sub domain or a record exists, the DNS server will use it to respond to the DNS request. If a sub domain or a record does not exists and you have an APP record configured at the zone apex then the APP record's request handler is called by the DNS server and the response returned by the DNS App is sent back to the requesting client.

A Sample DNS Zone With APP Records

I am running a sample DNS zone that has an APP record which is configured for a DNS App called "What Is My DNS". The DNS App essentially just returns the IP address of the client querying it and so can be used to find out the IP address of your DNS server. 

To try it, you can query for mydns.home.zare.im using nslookup on the command line and you will get a response back containing the IP address of your DNS server. If you query for the domain name directly to the name server ns1.technitium.net, you will get a response back with your own public IP address. You can see the source code of this DNS App here.

Creating DNS Apps

Since the DNS Apps are .NET based, to create your own DNS App you will require to have Visual Studio 2019 installed with .NET 5 SDK. The app itself is a .NET 5 class library project and requires two references to be added to the project namely, DnsApplicationCommon.dll and TechnitiumLibrary.Net.dll. Both of these DLLs are included in the DNS server setup and you can find them in the directory where the DNS server is installed.

Once you have the class library project ready with the two DLL references added, you can now create a class which implements IDnsApplicationRequestHandler interface. In here, there are two important functions to implement.

The first is InitializeAsync() which is called when the DNS App first starts or when the app config is updated from the web console to allow reloading the latest config. The app config is a simple text based config file for any initial config that the app may require e.g. if the app uses a database, you can have the database connection string stored as the config.

The second and the most important function is ProcessRequestAsync() which gets called by the DNS server when the request hits an APP record. This method provides the original request, the IP address of the client, and other relevant details that may be required to process the request. The response returned by this function is returned to the client.

The implementation uses Task based Async programming to allow you to scale the DNS application easily.

The IDnsApplicationRequestHandler interface also requires implementing two properties. The Description property allows you to provide a description for the app which gets displayed on the web console. And the ApplicationRecordDataTemplate property allows you to provide a template with the format of record data in the APP record that is expected. This template is displayed to the user to help with adding the APP record with the expected record data.

You can always refer to the code from the Default DNS App on GitHub to get your app working.

Deploying DNS Apps

Once you have the DNS App code ready, all you need to do is compile the code in Release mode and create a new zip file containing all the compiled files. In the DNS server web console, go to the Apps tab and click Install. Give a name for the app you are installing, browse the zip file that you had created, and proceed to install the app. Now as the app is installed, you will see it listed with the details like class path and the description on the web console. You can now go to the Zones tab and edit your primary zone to add an APP record for the DNS App.

Installing DNS App

You can now try to test your code by querying This Server using the DNS Client tab. The DNS Client will show you the output that your DNS App returns.

Conclusion

With DNS Apps feature, you can develop apps that provide simple split horizon responses or complex response based on things like geo-location and the health of the web server configured in the record. The apps can be coded to use databases with any business logic to process responses. This unique feature makes your DNS server even more powerful.

Technitium DNS Server v5 Released!

I am really happy to announce the release of Technitium DNS Server v5. This version is a major upgrade with many new core features, a lot of memory and CPU optimizations, and multiple bug fixes done. Download the latest update now!

Technitium DNS Server v5

Technitium DNS Server is a free, open source software that can be used by anyone be it a novice or an expert user. The server aims to have a user friendly approach, providing an easy to use web based GUI, and with defaults that allow the server to run out-of-the-box.

The DNS server can be used to self host domain names, used as a local resolver on a desktop or laptop computer, or used as a DNS server for the entire local network. It supports many useful and powerful features like blocking domain names using block lists, overriding records for any domain, use forwarders or conditional forwarders with DNS-over-TLS or DNS-over-HTTPS, and host your own DNS-over-TLS or DNS-over-HTTPS service.

The DNS Server is cross platform and can run on Windows, Linux and macOS. It has small footprint and thus can run even on a Raspberry Pi.

Once you have used Technitium DNS Server, you will realize how powerful it is and how silly it is to rely on your ISP's DNS servers.

Conditional Forwarder Zone

Features that you may find interesting in this release:

• QNAME minimization support in recursive resolver for privacy.
• ANAME propriety record support to allow using CNAME like feature at zone root.
• Primary and Secondary zone support with NOTIFY implementation and zone transfer support. 
• Stub zone support that allows the DNS server to keep track of the name servers of the zone.
• Conditional Forwarder zone support which allows to configure multiple forwarders for a specific domain name with all protocol support including DNS-over-HTTP or DNS-over-TLS protocols.
• Ability to override records of a live domain name using conditional forwarder or stub zone. This allows you to easily implements things like forced Google safe search or YouTube's restricted mode.
• Concurrent querying with more than one forwarder allows to get fastest response from multiple forwarders.
• Option to change the DNS Server local ports for TCP and UDP protocols. 

Read the change log to know more in details about the latest release.

Conditional Forwarder Zone with Overridden Records For Google Force Safe Search

The DNS Server code has been optimized for CPU, memory and concurrency. The server now notably has a very small memory footprint which allows loading a couple of million blocked domain names easily via the blocks list URLs on a Raspberry Pi with just 1 GB RAM. The time it takes to load the blocked lists too has improved significantly.

The DNS server now internally uses a new ByteTree data structure which is a complete lock less implementation allowing concurrent threads to do read and write operations. This allows the DNS server to handle large amount of concurrent requests easily while also allowing it to update the cache data parallelly.

With the limited hardware that is available with me for testing, the DNS server was load tested on a machine with Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz on a 1 Gbps wired Ethernet network. The server could resolve more than 2 million requests per minute with an average 30% CPU utilization consistently for 3 hours. The client machine that was used to bombard requests however would peak out at 100% CPU preventing from adding any more load on the server for the load test. This update is supposed to fix issues in the previous version that caused the CPU to peak, failing to handle load more that couple of thousand requests per second.

Any comment or feedback is really appreciated and helps a lot in adding new features and fixing bugs. Do send your feedback or support requests to support@technitium.com. For any feature request or reporting bug, do create an issue on GitHub.

The DNS Server code is available under GNU General Public Licence (GPL) v3 on GitHub.

Technitium DNS Server v1.3 Released!

Technitium DNS Server is an open source tool that can be used for self hosting a local DNS server for privacy & security or, used for experimentation/testing by software developers on their computer. It works out-of-the-box with no or minimal configuration and provides a user friendly web console accessible using any web browser.

Technitium DNS Server v1.3

Version 1.3 adds following awesome new features:

•  DNS-over-TLS and DNS-over-HTTPS forwarder protocol support.
• HTTP and SOCKS5 network proxy support.

The DNS Server is cross platform and can be deployed on Windows 10, Linux or macOS (using .NET Core or Mono Framework). Read this blog post to learn how to run DNS Server on Ubuntu.

Nobody really bothers about domain name resolution since it works automatically behind the scenes and is complex to understand. Most computer software use the operating system's DNS resolver that usually query the configured ISP's DNS server using UDP protocol. This way works well for most people but, your ISP can see and control what website you can visit even when the website employ HTTPS security. Not only that, some ISPs can redirect, block or inject content into non-HTTPS websites you visit even when you use a different DNS provider like Google DNS or Cloudflare DNS. Having Technitium DNS Server configured to use DNS-over-TLS or DNS-over-HTTPS forwarders, these privacy & security issues can be mitigated very effectively.

Developers regularly use the hosts file for configuring an IP address for a domain under testing. However, using the hosts file is cumbersome at times and can only be used to resolve domain name to an IP address. With a fully configurable DNS server running on your local machine, you can configure not just simple A records (for IP address) but, also configure other types of records like CNAME or MX etc. This allow you to have more control and power when you want to do testing that simulates the exact configuration that you have running on production.

Technitium DNS Server is open source and available under GNU General Public Licence (GPL) v3 on GitHub.

• Kademlia based Distributed Hash Table (DHT) implemented for allowing Bit Chat to rely less on torrent trackers for finding peers. DHT implementation uses a UDP based protocol to connect to other nodes.
• Socks 5 Proxy support implemented to allow Bit Chat users to hide behind a proxy. User can even configure Bit Chat to use Tor Network, which provides a Socks 5 interface. However, since Tor doesn't support routing UDP packets, user will have to rely on Http torrent trackers to find peer.

Bit Chat Socks 5 Proxy Config

• Bit Chat can now act as a TCP Relay for allowing other peers behind NAT to accept connection requests. This should allow two peers to connect with each other via a random 3rd peer. This feature depends on DHT module to find peers to start a TCP relay.
• Network Info feature added to allow user to get internet connectivity related information including UPnP port forwarding & Socks 5 proxy status information.

Bit Chat Network Info

As the number of Bit Chat users increase, the peer-to-peer connectivity will improve due to DHT and TCP relay features.

Bit Chat Version 3.0 Released With Upgraded Cryptography!

Technitium Bit Chat version 3.0 (alpha) is now available to download from the main website and via automatic update mechanism for existing installations. The software checks for new update automatically with every start but, you can also use the Check For Updates option in the main menu to get an update instantly.

The latest version has protocol level updates which makes it incompatible with the previous versions and thus all peers must use the updated version to be able to chat. You wont notice any changes in the user interface (UI) since the changes are only related to the protocol.

The primary aim of this update is to improve the cryptography implementation used in Bit Chat. The newly added code provides strong cryptography with following features:

• The new protocol (v3) implements Perfect Forward Secrecy (PFS) using Elliptic Curve Diffie-Hellman (ECDHE_RSA 256bits) and Diffie Hellman (DHE_RSA 2048bits) for ephemeral key exchange mechanism with RSA for authentication using certificate (Bit Chat profile certificate). Mono framework doesn't implement ECDHE algorithm and hence Linux version of Bit Chat can use only DHE algorithm while Windows version of Bit Chat is able to use both the algorithms. AES 256bits in CBC mode is used to encrypt the data as it was in previous protocol.
• Key re-negotiation feature is added to protocol to negotiate new ephemeral key for data encryption based on time and data transferred. This allows the encrypted data channel to remain always ON while ensuring the protocol security by using different ephemeral keys.
• Authenticated encryption (Encrypt-then-MAC) is implemented using HMAC-SHA256 to check if the encrypted data was authentic (that is, to check if the encrypted data was modified in any manner while in transit).
• In addition to profile certificate based authentication, pre-shared key is used to establish the encrypted channel. The pre-shared key used here is the Group Chat password that was set while creating the chat. So, using a password for your Group Chat will improve the protocol security.
• The security of encrypted profile file (which is stored on your computer and contains your RSA private key for the profile certificate) is also improved by implementing PBKFD2 using HMAC-SHA256 with 200,000 iterations. This implementation will improve security of the file against password cracking or brute force attacks.

The above features updates are in addition to the existing ones listed below:

• Peer-to-peer architecture similar to how Bittorrent works. Infact, Bit Chat uses Bittorrent trackers to find peers in your group chat. So, you connect directly to peers without any server in the middle! Another advantage is that the data is routed through shortest path, that is, if your friend uses Internet from the same service provider as that of you, then the communication is not going to leave the local network of the service provider. And if your friend is on private LAN network, the communication stays in the private network itself, so you don't even need Internet for private LAN chat!
• A complete end-to-end encryption with digital certificate (profile certificate) based authentication combined with peer-to-peer network means nobody can snoop on your messages and you can ensure the identity of your friends.
• Transfer huge files with ease! All peers in the group that participate in file transfer share the bandwidth. It works similar to how files are shared using Bittorrent but, in a close group of users. Also, files transfered are encrypted just like your messages.

The source code is updated on GitHub and you can inspect the TechnitiumLibrary.Security .Cryptography project for verifying the implementation. And as always, send your feedback to support@bitchat.im.
