The method used for this is VNC (Virtual Network Computing).
Before, trying anything, you need to know this. The machine that you use to access a Remote machine is called the client. And the Remote Desktop is the server. In VNC what happens is, we install a VNC server software in server side (Remote machine) and access it though a client software.
Let's get in to business. It's pretty easy. Here I'm telling doing remote desktop for a Linux machine from any environment. I did this Ubuntu 10.04 Lucid Lynx but applicable to other distros as well.
- In Server (Remote machine), first install vnc4server package from Synaptic Package Manager. (Go to System -> Administration -> Synaptic Package Manager) Search for vnc.
- Install the package named vnc4server. Or, in terminal,
sudo apt-get install vnc4server
- Then, go to client machine and install xvnc4viewer. By terminal or from Synaptic. This is accesses the server and displays the virtual desktop.
apt-get install xvnc4viewerNow the installation is over. How to run?
- First, create a server instance in the Remote machine you want to connect to by, entering command 'vnc4server' in terminal. Your output would look similar to below if everything went smooth.
kasun@uom:~$ vnc4serverNOTE: In the first run it will ask to set a password. Give a strong password to it as anyone with it can access your server if it's turned on.
New 'uom:1 (kasun)' desktop is uom:1
Starting applications specified in /home/kasun/.vnc/xstartup
Log file is /home/kasun/.vnc/uom:1.log
You can create any number instances as you like. They will be numbered as <host>:<id> which will be distinguised by a port number. You can know the port number by looking at the log file from ~/.vnc/<host>:<id>.log. ex. cat ~/.vnc/uom\:1.log . You need port to access the server instance. Port number is generally 5901 or nearby. And server IP address (do ifconfig)
Now go to Client.
- Run xvnc4viewer . It will ask for the server to connect to: give it in the format <ip>:<port> ex. 10.100.1.100:5901
- OR, there are Microsoft Windows alternatives available such as RealVNC. Download it from here. (Filling the form is not compulsory!)
