Remote desktop protocol (RDP)

remote Desktop Protocol(RDP)

Remote desktop protocol (RDP) is a secure network rule designed for remote management, similarly as for remote access to virtual desktops, applications, and an RDP terminal server.
RDP allows network administrators to remotely diagnose and resolve problems individual subscribers encounter. RDP is on the market for many versions of the Windows, macOS or as an open-source.
Noteworthy properties of RDP include encryption, revolving credit authentication, bandwidth reduction, resource sharing, the power to use multiple displays and therefore the ability to disconnect temporarily without logging off. RDP also allows for the redirection of functions like audio and printing.
RDP can support up to 64,000 independent channels for data transmission. Data is encrypted using 128-bit keys, and therefore the bandwidth reduction feature optimizes the info transfer rate in low-speed connections.
The RDP protocol is meant to supply remote access through port 3389. An RDP-enabled application or service packages the info that’s to be transmitted, and therefore the Microsoft Communications Service directs the info to an RDP channel. From there, the software system encrypts the RDP data and adds it to a frame so it is transmitted.
The Terminal Server Device Redirector Driver handles all RDP protocol activity. This driver is formed of subcomponents like the RDP driver (Wdtshare.sys), which handles user interfaces, transfers, encryption, compression, and framing. The transport driver (Tdtcp.sys) is chargeable for packaging the protocol in such the simplest way that enables it to be sent across a TCP/IP network.

The Remote Window Isn’t the Correct Size

Incorrect window size is another common Remote Desktop Connection issue. after you create the remote desktop connection, the window is just too large, too small, or doesn’t correlate to the settings you input.
You have two potential fixes here.
First, you’ll be able to force the Remote Desktop connection to use a particular size via the Run function. Hit Windows key + R, then input:

mstsc.exe /h:X /w:X

Where “X” is that the height and width of the Remote Desktop viewing window you desire. Remote Desktop will remember your settings for future remote viewing settings.
The Remote Desktop Connection client encompasses a handy screen resolution slider that scrolls from 640×480 up to Full Screen for your screen. certify to line the slider to Full Screen if you wish a full-screen remote connection for every connection.

How to Save Your Remote Desktop Connection Custom Settings

If you often hook up with several different servers or clients, saving a custom configuration for every Remote Desktop will save time within the future. you’ll be able to set the optimum width, height, and color settings for every server or terminal.
Open the Remote Desktop Connection dialog, then select Show Options. you’ll now see the Connection settings options. Select Save As, specify your save location, then select Save to make a custom Remote Desktop Connection file (.RDP).
Now, browse to the Remote Desktop Connection configuration file. you’ll be able to edit the configuration file employing a text editor, like Notepad or Notepad++. Right-click the configuration file and choose Open with…, then select your text editor.
The first four lines show your remote connection screen size options (plus whether multi-monitor mode is available). you’ll be able to edit the screen mode to line whether the remote window session appears full screen. for example, “id:i:2” sets full screen, whereas “id:i:1” sets the remote connection to seem in an exceedingly window.
If you set the screen mode to “2” for full screen, the desktop width and desktop height automatically match the screen size of the host client. However, if you’re using screen mode “1,” you’ll be able to use the desktop width and desktop height settings to line a selected window size.
After you confirm your settings, add the subsequent string to the tip of the file:

smart sizing:i:1

Smart sizing allows you to dynamically alter your screen settings without messing around with configuration files while the Remote Desktop connection is active. However, you must add the string for each custom configuration you create.

Ubuntu server RDP – option 1 – xrdp

Access via SSH and install XRDP

sudo apt install xrdp
sudo systemctl enable xrdp

Ubuntu server RDP – option 2 – vnc

Another option with full remote desktop functionality is VNC. This requires a client application on the Windows PC and a server on Ubuntu.
On the remote PC, install the TightVNC Server component after checking for updates:

sudo apt update

Then install the server utility:

sudo apt install tightvncserver

You’ll then need to run it:

sudo tightvncserver
At this point, you’ll be prompted to set a password for the connection. You’ll also be given a desktop number, usually:1. Keep a note of this.
 

Now that TightVNC Server is set up on Ubuntu, you’ll need to install the client on Windows. This can be downloaded from www.tightvnc.com/download.php—make sure you choose the right version, as it is available in 32-bit and 64-bit flavors.

TightVNC tools are only available as a bundle, so once installed, look for TightVNC Viewer in Windows search.

Once you’ve launched the viewer, input the IP address of the Ubuntu box in Remote Host, followed by the desktop number. So, it might look like this:

192.168.0.99:1

Input the password when prompted and commence your remote desktop activity!

TightVNC can be set More Secure – By default, TightVNC will encrypt your password, but nothing else. This makes it insecure for connections over the internet. Fortunately, it can be made more secure, thanks to SSH and Xming.
To use this, download and install the Xming tool for Windows from Sourceforge. Once this is done, look for the desktop shortcut, right-click, and choose Properties.
Click Apply to save the change, then OK. Double-click the icon to run Xming, then open PuTTY. Here, expand the menu on the left to Connection > SSH > X11.
Check Enable X11 Forwarding, then return to Session at the top of the menu.

It will be most secure of RDP over SSH or VNC over SSH (Mixing VNC with SSH) is used
