No longer supported. 14 | 15 | Ver 2.0+ is suitable for Shandong University, Qingdao Campus, since March 2019. 16 | 17 | ## Copyright 18 | 19 | Copyright © 2018-2022 Sad Pencil 20 | 21 | MIT License 22 | 23 | ## Get the executable 24 | 25 | Static builds are available [here](https://github.com/SadPencil/sdunetd/releases). 26 | 27 | You can also compile by your self. 28 | 29 | Rename the executable to `sdunetd`. 30 | 31 | ## Generate a configuration file 32 | 33 | Run the program without any parameters and it will guide you to create a configuration file. 34 | 35 | ```bash 36 | ./sdunetd 37 | ``` 38 | 39 | ## Installation on Linux (based on systemd) 40 | 41 | 1. Copy the executable to `/usr/local/bin`, and rename it to `sdunetd` 42 | 2. `chmod +x /usr/local/bin/sdunetd` 43 | 3. Create a configuration file at `/etc/sdunetd/config.json` 44 | 4. `vi /etc/systemd/system/sdunetd.service` 45 | 46 | ```ini 47 | [Unit] 48 | Description=sdunetd 49 | After=network.target 50 | Wants=network.target 51 | 52 | [Service] 53 | Type=simple 54 | PrivateTmp=true 55 | ExecStart=/usr/local/bin/sdunetd -c /etc/sdunetd/config.json -m 56 | Restart=always 57 | 58 | [Install] 59 | WantedBy=multi-user.target 60 | ``` 61 | 62 | 6. `systemctl daemon-reload` 63 | 7. `systemctl enable sdunetd` 64 | 8. `systemctl start sdunetd` 65 | 66 | ## Installation on OpenWRT 67 | 68 | 1. Copy the executable to `/usr/local/bin`, and rename it to `sdunetd` 69 | 70 | - Note: You MUST choose proper builds according to `/proc/cpuinfo`. 71 | 72 | - Note: It might take a few minutes to copy a large file to the router. 73 | 74 | 2. `chmod +x /usr/local/bin/sdunetd` 75 | 3. Create a configuration file at `/etc/sdunetd/config.json` 76 | 4. `touch /etc/init.d/sdunetd` 77 | 5. `chmod +x /etc/init.d/sdunetd` 78 | 6. `vi /etc/init.d/sdunetd` 79 | 80 | ```shell 81 | #!/bin/sh /etc/rc.common 82 | 83 | START=60 84 | 85 | start() { 86 | (/usr/local/bin/sdunetd -c /etc/sdunetd/config.json -m -o - 2>&1 | logger -t sdunetd) & 87 | } 88 | 89 | stop() { 90 | killall sdunetd 91 | } 92 | ``` 93 | 94 | 7. `/etc/init.d/sdunetd enable` 95 | 8. `/etc/init.d/sdunetd start` 96 | 97 | ## Installation on Windows 98 | 99 | Although it is okay to create a shortcut at `startup` folder, it is better to create a service. `srvany` is a 32-bit 100 | program provided by Microsoft to let any program become a service, and you can get a 64-bit implementation at 101 | repo [birkett/srvany-ng](https://github.com/birkett/srvany-ng.git). 102 | 103 | Example: 104 | 105 | 0. Suppose `sdunetd.exe` `config.json` and `srvany.exe` are all placed at `C:\Program Files\sdunetd` 106 | 107 | 1. Create a service named `sdunetd` 108 | 109 | ```winbatch 110 | sc create "sdunetd" start= auto binPath= "C:\Program Files\sdunetd\srvany.exe" 111 | ``` 112 | 113 | 2. Import the following to the registry 114 | 115 | ```ini 116 | Windows Registry Editor Version 5.00 117 | [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\sdunetd\Parameters] 118 | "Application"="C:\\Program Files\\sdunetd\\srvany.exe" 119 | "AppDirectory"="C:\\Program Files\\sdunetd" 120 | "AppParameters"="-c \"C:\\Program Files\\sdunetd\\config.json\"" 121 | ``` 122 | 123 | ## Dynamic DNS 124 | 125 | We recommend [TimothyYe/GoDNS](https://github.com/TimothyYe/godns). In the configuration file, set `ip_interface` to 126 | your network interface to help GoDNS get the real IPv4 address. 127 | Click [here](https://github.com/TimothyYe/godns#get-an-ip-address-from-the-interface) to get detailed help. 128 | 129 | However, you can't use GoDNS behind a NAT router because the Internet traffic at SDU-Qingdao is being masqueraded, so 130 | that online services can't determine your real IPv4 address. 131 | 132 | `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 133 | need this feature, open an issue at [sdunetd](https://github.com/SadPencil/sdunetd/issues) so that we can fork a special 134 | version of GoDNS which is suitable for SDU-Qingdao. 135 | 136 | ## How to compile sdunetd 137 | 138 | Go 1.13 or higher version is **required**. 139 | 140 | This project uses **go module**. If you live in Mainland China, you might need to configure a proxy 141 | like [goproxy.cn](https://github.com/goproxy/goproxy.cn) to execute the following code. 142 | 143 | ```bash 144 | git clone https://github.com/SadPencil/sdunetd 145 | cd sdunetd 146 | make 147 | ``` 148 | 149 | To build for all supported platform: 150 | 151 | ```bash 152 | make all 153 | ``` 154 | -------------------------------------------------------------------------------- /UPDATELOG.md: -------------------------------------------------------------------------------- 1 | # Update log of sdunetd 2 | 3 | ## [v2.4.0](https://github.com/SadPencil/sdunetd/releases/tag/v2.4.0) 4 | - The network section is re-added in the configuration file. 5 | The strict mode is now re-supported, behaves like curl, but it is now a Linux-specific feature. See [this page](https://stackoverflow.com/a/73295452/7774607) for technical details. 6 | - Breaking change: the configuration file is now updated. Please re-generate the config file. 7 | - Breaking change: the version parameter is changed to `-V` instead of `-v`. 8 | - Breaking change: `-v` now stands for verbose output. 9 | - Breaking change: the log is now by default written to stderr, instead of stdout. 10 | - Breaking change: the log output is now controlled by `-o` parameter, instead of the configuration file. 11 | - Retries are now supported, specified in the configuration file. 12 | 13 | ## [v2.3.1](https://github.com/SadPencil/sdunetd/releases/tag/v2.3.1) 14 | - The network section is removed in the configuration file 15 | - Support detecting the Internet via either the auth server or the online service. In the configuration file, set `online_detection_method` to `auth` for the auth server, or `ms` for the detection url by Microsoft 16 | 17 | ## [v2.2.2](https://github.com/SadPencil/sdunetd/releases/tag/v2.2.2) 18 | 19 | The 2.2.2 version. Suitable for Shandong University, Qingdao Campus, since March 2019. 20 | 21 | Update log: 22 | 23 | - add `-l` flag to logout 24 | - add some tips on the guide 25 | 26 | ## [v2.2](https://github.com/SadPencil/sdunetd/releases/tag/v2.2) 27 | 28 | The 2.2 version. Suitable for Shandong University, Qingdao Campus, since March 2019. 29 | 30 | Update log: 31 | 32 | - add jsonp callback for disgusting 33 | 34 | ## [v2.1](https://github.com/SadPencil/sdunetd/releases/tag/v2.1) 35 | 36 | The 2.1 version. Suitable for Shandong University, Qingdao Campus, since March 2019. 37 | 38 | Update log: 39 | 40 | - `-a` flag will only output the IP address 41 | - add `-t` flag 42 | - will check whether the authenticate server reject the login, and output the given error message if so. 43 | - the return value when `-a`, `-t`, `-f` is enabled is meaningful. Returning a zero value means there is no error occurs, and vise versa. 44 | 45 | ## [v2.0](https://github.com/SadPencil/sdunetd/releases/tag/v2.0) 46 | 47 | The 2.0 version. Suitable for Shandong University, Qingdao Campus, since March 2019. 48 | 49 | ## [v1.1](https://github.com/SadPencil/sdunetd/releases/tag/v1.1) 50 | 51 | used to be suitable for SDU-Qingdao, until March 2019 52 | -------------------------------------------------------------------------------- /checks.go: -------------------------------------------------------------------------------- 1 | /* 2 | Copyright © 2018-2022 Sad Pencil 3 | Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the “Software”), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: 4 | The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software. 5 | THE SOFTWARE IS PROVIDED “AS IS”, WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
