Starting Remote Desktop Protocol server sesman already running xrdp already running
Introduction What s xRDP? Taking directly from the xRDP website. Xrdp is the main server accepting connections from RDP clients. Xrdp contains the RDP, security, MCS, ISO, and TCP layers, a simple window manager and a few controls. Its a multi threaded single process server. It is in this process were the central management of the sessions are maintained. Central management includes shadowing a session and administrating pop ups to users. Xrdp is control by the configuration file xrdp.ini. RDP has 3 security levels between the RDP server and RDP client. Low, medium and high. Low is 40 bit, data from the client to server is encrypted, medium is 40 bit encryption both ways and high is 128 bit encryption both ways. Xrdp currently supports all 3 encryption levels via the xrdp.ini file. RSA key exchange is used with both client and server randoms to establish the RC4 keys before the client connect. Modules are loaded at runtime to provide the real functionality. Many different modules can be created to present one of many different desktops to the user. The modules are loadable to conserve memory and support both GPL and non GPL modules. Multi threaded to provide optimal user performance. One client cant slow them all down. One multi threaded process is also required for session shadowing with any module. The module doesnt have to consider shadowing, the xrdp server does it. For example, you could shadow a VNC, RDP or a custom module session all from the same shadowing tool. Build in window manager for sending pop ups to any user running any module. Also can be user to provide connection errors or prompts. libvnc Libvnc, a VNC module for xrdp. Libvnc provides a connection to VNC servers. Its a simple client only supporting a few VNC encodings(raw, cursor, copyrect). Emphasis on being small and fast. Normally, the xrdp server and the Xvnc server are the same machine so bitmap compression encodings would only slow down the session. librdp Librdp, an RDP module for xrdp. Librdp provides a connection to RDP servers. It only supports RDP4 connections currently. sesman Sesman, the session manager. Sesman is xrdps session manager. Xrdp connect to sesman to verify the user name / password, and also starts the user session if credentials are ok. This is a multi process / Linux only session manager. Sessions can be started or viewed from the command line via sesrun. STEP 1 Setup xRDP Same onyour CUBE Linux Compute Server:
STEP 2.0.0 (optional) How To Setup xRDP Same Session Remote Desktop on your CUBE Linux Compute Server: 2.0.1) Login as root via SSH 2.0.2) cd/etc/xrdp/ 2.0.3) Editthe xrdp.ini file as the root user. Open and edit the xrdp.ini file. For same session sharing, locate and modify the last line of the xrdp.ini configuration file.
vi/etc/X11/Xrdp.ini 2.0.4) Save the xrdp.ini and restart the xrdp service (command is below)
2.0.5) Next, For you MPI local or distributed Users, edit the following files
2.0.6) For users of xRDP same session management.
STEP 2.1.0 Open the Microsoft Remote Desktop client on your Windows Machine.
(see screen capture below) STEP 2.2.0 Pay Attention to a few things while logging in.
(see screen capture below)
STEP 2.3.0 Login process for you the secondary RDP user:
(see screen capture below)
(see screen capture below) Final Thoughts pertaining toxRDP/remote desktop connections and screen sharing on 64-bit Linux. Other/Secondary users who do not need to login toan already running/existing remote desktop session. Do not enter the port number the server, leave the port setting as -1. Logging in this way ensure you will have aunique NONSHAREDremote desktop experience. ThePrimary or the originator of the xRDP session. Do not use SYSTEM > LOGOUT to close the RDP session.Simply minimize the session orclick the X to close your window out.

Uh Oh! If the output of these commands look something like what you see below: $ glxinfo|head -n 25 Then please add this information to the end of the xorg.conf file and reboot the server.

The installer can be run as a separate step in the process, or can be run at a later time to get updates, etc. Some of the more important commandline options of nvidia-installer are: nvidia-installer options uninstall latest update ui=none This how to install for xRDP was installed ontoa CentOS release 6.7 (Final) Linux using PADT, Inc.
