Devolutions/IronRDP: Rust implementation of the Microsoft Remote Desktop Protocol (RDP)

A collection of Rust crates providing an implementation of the Microsoft Remote Desktop Protocol, with a focus on security.

Supported codecs:

• Uncompressed raw bitmap
• Interleaved Run-Length Encoding (RLE) Bitmap Codec
• RDP 6.0 Bitmap Compression
• Microsoft RemoteFX (RFX)

A full-fledged RDP client based on IronRDP crates suite, and implemented using non-blocking, asynchronous I/O.

cargo run --bin ironrdp-client -- HOSTNAME> --username USERNAME> --password PASSWORD>

Example of utilizing IronRDP in a blocking, synchronous fashion.

This example showcases the use of IronRDP in a blocking manner. It
demonstrates how to create a basic RDP client with just a few hundred lines
of code by leveraging the IronRDP crates suite.

In this basic client implementation, the client establishes a connection
with the destination server, decodes incoming graphics updates, and saves the
resulting output as a BMP image file on the disk.

cargo run --example=screenshot -- --host HOSTNAME> --username USERNAME> --password PASSWORD> --output out.bmp

Run the following PowerShell commands, and reboot.

Set-ItemProperty -Path 'HKLM:\Software\Policies\Microsoft\Windows NT\Terminal Services' -Name 'ColorDepth' -Type DWORD -Value 5
Set-ItemProperty -Path 'HKLM:\Software\Policies\Microsoft\Windows NT\Terminal Services' -Name 'fEnableVirtualizedGraphics' -Type DWORD -Value 1

Alternatively, you may change a few group policies using gpedit.msc:

1. Run gpedit.msc.

2. Enable Computer Configuration/Administrative Templates/Windows Components/Remote Desktop Services/Remote Desktop Session Host/Remote Session Environment/RemoteFX for Windows Server 2008 R2/Configure RemoteFX

3. Enable Computer Configuration/Administrative Templates/Windows Components/Remote Desktop Services/Remote Desktop Session Host/Remote Session Environment/Enable RemoteFX encoding for RemoteFX clients designed for Windows Server 2008 R2 SP1

4. Enable Computer Configuration/Administrative Templates/Windows Components/Remote Desktop Services/Remote Desktop Session Host/Remote Session Environment/Limit maximum color depth

5. Reboot.
