xrdp - an open source RDP server

Overview

xrdp provides a graphical login to remote machines using Microsoft Remote Desktop Protocol (RDP). xrdp accepts connections from a variety of RDP clients: FreeRDP, rdesktop, NeutrinoRDP and Microsoft Remote Desktop Client (for Windows, Mac OS, iOS and Android).

RDP transport is encrypted using TLS by default.

Features

Remote Desktop Access

Connect to a Linux desktop using RDP from anywhere (requires xorgxrdp Xorg module)
Reconnect to an existing session
Session resizing
RDP/VNC proxy (connect to another RDP/VNC server via xrdp)

Access to Remote Resources

two-way clipboard transfer (text, bitmap, file)
audio redirection (requires to build additional modules)
drive redirection (mount local client drives on remote machine)

Quick Start

Most Linux distributions should distribute the latest release of xrdp in their repository. You would need xrdp and xorgxrdp packages for the best experience. It is recommended that xrdp depends on xorgxrdp, so it should be sufficient to install xrdp. If xorgxrdp is not provided, use Xvnc server.

xrdp listens on 3389/tcp. Make sure your firewall accepts connection to 3389/tcp from where you want to access.

Ubuntu / Debian

apt install xrdp

RedHat / CentOS / Fedora

On RedHat and CentOS, make sure to enable EPEL packages first.

yum install epel-release

Install xrdp package.

yum install xrdp

yum is being replaced with dnf, so you may need to use dnf instead of yum in the above commands.

Environment

xrdp primarily targets to GNU/Linux. Tested on x86, x86_64, SPARC and PowerPC.

xorgxrdp and RemoteFX Codec have special optimization for x86 and x86_64 using SIMD instructions.

FreeBSD is not a primary target of xrdp. It is working on FreeBSD except for the drive redirection feature.

Other operating systems such as macOS are not supported so far, but we welcome your contributions.

Compiling

Prerequisites

To compile xrdp from the packaged sources, you need basic build tools - a compiler (gcc or clang) and the make program. Additionally, you would need openssl-devel, pam-devel, libX11-devel, libXfixes-devel, libXrandr-devel. More additional software would be needed depending on your configuration.

To compile xrdp from a checked out git repository, you would additionally need autoconf, automake, libtool and pkgconfig.

Get the source and build it

If compiling from the packaged source, unpack the tarball and change to the resulting directory.

If compiling from a checked out repository, please make sure you've got the submodules cloned too (use git clone --recursive https://github.com/neutrinolabs/xrdp)

Then run following commands to compile and install xrdp:

./bootstrap
./configure
make
sudo make install

If you want to use audio redirection, you need to build and install additional pulseaudio modules. The build instructions can be found at wiki.
