Static builds are available here.

You can also compile by your self.

Rename the executable to sdunetd.

Run the program without any parameters and it will guide you to create a configuration file.

./sdunetd

1. Copy the executable to /usr/local/bin, and rename it to sdunetd
2. chmod +x /usr/local/bin/sdunetd
3. Create a configuration file at /etc/sdunetd/config.json
4. vi /etc/systemd/system/sdunetd.service

[Unit]
Description=sdunetd
After=network.target
Wants=network.target

[Service]
Type=simple
PrivateTmp=true
ExecStart=/usr/local/bin/sdunetd -c /etc/sdunetd/config.json -m
Restart=always

[Install]
WantedBy=multi-user.target

6. systemctl daemon-reload
7. systemctl enable sdunetd
8. systemctl start sdunetd

1. Copy the executable to /usr/local/bin, and rename it to sdunetd

• Note: You MUST choose proper builds according to /proc/cpuinfo.

• Note: It might take a few minutes to copy a large file to the router.

2. chmod +x /usr/local/bin/sdunetd
3. Create a configuration file at /etc/sdunetd/config.json
4. touch /etc/init.d/sdunetd
5. chmod +x /etc/init.d/sdunetd
6. vi /etc/init.d/sdunetd

#!/bin/sh /etc/rc.common

START=60
 
start() { 
  (/usr/local/bin/sdunetd -c /etc/sdunetd/config.json -m -o - 2>&1 | logger -t sdunetd) &
}

stop() { 
  killall sdunetd
}

7. /etc/init.d/sdunetd enable
8. /etc/init.d/sdunetd start

Although it is okay to create a shortcut at startup folder, it is better to create a service. srvany is a 32-bit program provided by Microsoft to let any program become a service, and you can get a 64-bit implementation at repo birkett/srvany-ng.

Example:

0. Suppose sdunetd.exe config.json and srvany.exe are all placed at C:\Program Files\sdunetd

1. Create a service named sdunetd

sc create "sdunetd" start= auto binPath= "C:\Program Files\sdunetd\srvany.exe"

2. Import the following to the registry

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\sdunetd\Parameters]
"Application"="C:\\Program Files\\sdunetd\\srvany.exe"
"AppDirectory"="C:\\Program Files\\sdunetd"
"AppParameters"="-c \"C:\\Program Files\\sdunetd\\config.json\""

We recommend TimothyYe/GoDNS. In the configuration file, set ip_interface to your network interface to help GoDNS get the real IPv4 address. Click here to get detailed help.

However, you can't use GoDNS behind a NAT router because the Internet traffic at SDU-Qingdao is being masqueraded, so that online services can't determine your real IPv4 address.

sdunetd is able to detect your real IPv4 address at SDU-Qingdao no matter you are under a router or not. So, if you do need this feature, open an issue at sdunetd so that we can fork a special version of GoDNS which is suitable for SDU-Qingdao.

Go 1.13 or higher version is required.

This project uses go module. If you live in Mainland China, you might need to configure a proxy like goproxy.cn to execute the following code.

git clone https://github.com/SadPencil/sdunetd
cd sdunetd
make

To build for all supported platform:

make all
