Rustdesk-ID-Change

• The script use to change the rustdesk ID. As a open source remote control software, the "once good" a software can not manually change the ID even though you have host your own ID server or relay server.
• That sucks, I gathered the issue in the rustdesk and paied my effort to try to fix this problem. Both Windows, Linux, and MacOS works
• If you want to know more detail about how to id change works, you can look into the source code of those file
• Actually, it is pretty simple to reverse engineer the rustdesk id change, only need to change the toml file with string 'id = "desired_id"', and then the enc_id corresponding to this id will be generated.
• Even more, the enc_id, the password, the key_paris, are all separated, it means that if you have the enc_id of the desired id, then you can change the id of rustdesk while maintaining all other settings unchanged.

The script to modify the rustdesk id of windows, linux, and MacOS

• Both can run remotely, it will automatically restart the rustdesk service
• The best way is to use ssh to see how it works and the process
• Since the rustdesk will down when you input the new ID name
• Windows shell may not be able to enter the powershell mode)
• Windows using the irm url | iex to execute (url -> powershell file)
• Linux using the bash script to run it
• MacOs using the bash script to run it

The logic behind the win id change(v1.3.8 verified)

General process: Back toml file -> Add a new line to toml file (id = "desired_id") -> start the rustdesk

• Write the powershell script file
• Using nginx to host them
• Execute irm url | iex
  • irm -> Invoke-Expression
  • iex -> Invoke-RestMethod

The logic behind the linux id change (v1.3.8 verified)

General process: Back toml file -> generate enc_id -> inject this enc_id to the original toml file

• Stop rustdesk service: systemctl stop rustdesk.service
• Back up original toml file: cp RustDesk.toml RustDesk.toml.bak
• Write the line (id = "desiredID") to file RustDesk.toml
• Start rustdesk service to see the encID value
  • systemctl start rustdesk.service
  • cat RustDesk.toml (you will see the encryped id value)
• Substitute the original encID with the desired one
• Make the file unmutable: chattr +i Rustdesk.toml
• Start the rustdesk to see the final result

The logic behind the MacOS id change (v1.3.9 verified)

General process: back toml file -> generate enc_id (new toml file) -> restore password

• plist file location: /Users/jona/library/Preferences/com.carriez.rustdesk.plist
• RustDesk.toml file location: /Users/jona/library/Preferences/com.carriez.RustDesk/RustDesk.toml
• MacOS's script is diff with the one in the linux
  • Because when we execute the commad equivalent to the 'systemctl start rustdesk.service'
  • The GUI of MacOS rustdesk opened automatically which will autogenerate the toml file based on the new desired id
  • So all the settings are diff with the previous one and the password is initially empty
  • Thus we extract the password value from the original toml file and inject it to the new toml file
  • And then make it immutable
