SmartDNS-rs

English | 中文

SmartDNS-rs 🐋 is a local DNS server imspired by C SmartDNS to accepts DNS query requests from local clients, obtains DNS query results from multiple upstream DNS servers, and returns the fastest access results to clients. Avoiding DNS pollution and improving network access speed, supports high-performance ad filtering.

Features

Multiple upstream DNS servers

Supports configuring multiple upstream DNS servers and query at the same time.the query will not be affected, Even if there is a DNS server exception.
Return the fastest IP address

Supports finding the fastest access IP address from the IP address list of the domain name and returning it to the client to avoid DNS pollution and improve network access speed.
Support for multiple query protocols

Supports UDP, TCP, DoT, DoQ, DoH, DoH3 queries and service, and non-53 port queries, effectively avoiding DNS pollution and protect privacy, and support query DNS over socks5, http proxy.
Domain IP address specification

Supports configuring IP address of specific domain to achieve the effect of advertising filtering, and avoid malicious websites.
DNS domain forwarding

Supports DNS forwarding, ipset and nftables. Support setting the domain result to ipset and nftset set when speed check fails.
Windows / MacOS / Linux multi-platform support

Supports installing as a service and running it at startup.
Support IPV4, IPV6 dual stack

Supports IPV4, IPV6 network, support query A, AAAA record, dual-stack IP selection, and filter IPV6 AAAA record.
DNS64

Supports DNS64 translation.
High performance, low resource consumption

Tokio-based multi-threaded asynchronous I/O model; caches query results; supports most-used domain name expired prefetching, query '0' milliseconds, without eliminating the impact of DoH and DoT encryption.

Note: The C version of smartdns is very functional, but because it only supports Linux, while MacOS and Windows can only be supported through Docker or WSL. Therefore, I want to develop a rust version of SmartDNS that supports compiling to Windows, MacOS, Linux and Android Termux environment to run, and is compatible with its configuration.

It is still under development, please do not use it in production environment, welcome to try and provide feedback.

Please refer to TODO for the function coverage

Installing

MacOS

If you have installed brew, you can directly use the following command to install.
```
brew update
brew install smartdns
```
Note: Listening on port 53 requires root permission, so sudo is required.

The command sudo smartdns service start for brew installed smartdns is the same as sudo brew services start smartdns.

If you don't have brew installed, just download the compiled program compression package and install it as below.
Windows / Linux

Go to here to download the package and decompress it.
1. Get help
```
./smartdns help
```
2. Run as foreground, easy to check the running status
```
./smartdns run -c ./smartdns.conf -v
```
  - -v is enabled to print debug logs.
3. Run as background service, run automatically at startup
  
  Get help of service management commands.
```
./smartdns service help
```
  Note: Installed as a system service, administrator / root permissions are required.
  
  Service management is compatible with all systems, call sc on Windows; call launchctl or brew on MacOS; call Systemd or OpenRc on Linux.

Configuration

The following is the simplest example configuration

# Listen on local port 53
bind 127.0.0.1:53  

# Configure bootstrap-dns, if not configured, call the system_conf, 
# it is recommended to configure, so that it will be encrypted.
server https://1.1.1.1/dns-query  -bootstrap-dns -exclude-default-group
server https://8.8.8.8/dns-query  -bootstrap-dns -exclude-default-group

# Configure default upstream server
server https://cloudflare-dns/dns-query
server https://dns.quad9.net/dns-query
server https://dns.google/dns-query

# Configure the Office(Home) upstream server
server 192.168.1.1 -exclude-default-group -group office

# Domain names ending with ofc are forwarded to the office group for resolution
nameserver /ofc/office

# Set static IP for domain name
address /test.example.com/1.2.3.5

# Block Domains (Ad Blocking)
address /ads.example.com/#

# The following features are not yet supported in the [C SmartDNS](https://github.com/pymumu/smartdns) and are only applicable to SmartDNS-rs.
# Configure DoH3
server-h3 1.1.1.1

# Configure DoQ
server-quic unfiltered.adguard-dns.com

For more advanced configurations, please refer to here , and refer to TODO for the function coverage.

Building

Assuming you have installed Rust, then you can open the terminal and execute these commands:

git clone https://github.com/mokeyish/smartdns-rs.git
cd smartdns-rs

# install https://github.com/casey/just
cargo install just

# build
just build

# print help
./target/release/smartdns --help

# run
sudo ./target/release/smartdns run -c ./etc/smartdns/smartdns.conf

For cross-compilation, it is recommended to use cross (requires Docker).
