This article provides information on how to install and configure a VNC server on RedHat Enterprise Linux (RHEL) 6. The result will be either package vnc-server is not installed or If you are running CentOS 6, the server is: tigervnc-server not: vnc-. This installs latest version of RPMs: tigervnc-server-module, tigervnc and tigervnc-server. Configuring VNC server. 1. Edit the “/etc/sysconfig/vncservers” file.

If you completely disabled your firewall, you should now be good to go. If however you cannot connect, it might be that you have a firewall blocking you. We need to allow connections on port through the Linux firewall. If you added two users to your VNC server configuration file you will need to open up port as well.

Each additional user added gets the next port number, but in my example I only added one. If you are having problems, try this and then see if you can connect. You will need to be root to execute the command. The firewall exception we just added does NOT persist through reboots. In order to make the change permanent, use the following:.

Enter the password you set earlier and you should see your Linux desktop:. I get connection refused error now. Was getting timeouts before. Anything else that needs to be done? You are commenting using your WordPress. You are commenting using your Google account.

Access is also possible from a Windows system. There are a number of VNC packages available for Windows. Enter the password if one is required. The screen should load and display the remote desktop. You may also enter the port number in the form hostname screen 0 in VNC uses port TightVNC assumes port if none is specified but when we look at setting up additional desktops later in this chapter we will need to specify port numbers in order to connect. The remote desktop configurations we have explored so far in this chapter are considered to be insecure because no encryption is used.

This is acceptable when the remote connection does not extend outside of an internal network protected by a firewall. When a remote session is required over an internet connection a more secure option is needed. This is achieved by tunneling the remote desktop through a secure shell SSH connection. The ssh server is installed and activated by default on RHEL 6 systems. Assuming the SSH server is installed and active it is time to move to the other system. At the other system, log in to the remote system using the following command, which will establish the secure tunnel between the two systems:.

In the above example, hostname is either the hostname or IP address of the remote system. Log in using your account and password. The secure connection is now established and it is time to launch vncviewer so that it uses the secure tunnel. Leaving the ssh session running in the other terminal window, launch another terminal and enter the following command:. The vncviewer session will prompt for a password if one is required, and then launch the VNC viewer providing secure access to your desktop environment.

In the above example we left the ssh tunnel session running in a terminal window. If you would prefer to run the ssh session in the background, this can be achieved by using the —f and —N flags when initiating the connection:. The above command will prompt for a password for the remote server and then establish the connection in the background, leaving the terminal window available for other tasks. If you are connecting to the remote desktop from outside the firewall keep in mind that the IP address for the ssh connection will be the external IP address provided by your ISP, not the LAN IP address of the remote system since this IP address is not visible to those outside the firewall.

You will also need to configure your firewall to forward port 22 for the ssh connection to the IP address of the system running the desktop. It is not necessary to forward port Steps to perform port forwarding differ between firewalls, so refer to the documentation for your firewall, router or wireless base station for details specific to your configuration. A similar approach is taken to establishing a secure desktop session from a Windows system to an RHEL server.

Assuming that you have a VNC client installed as described above the one remaining requirement is a Windows ssh client. Once PuTTY is downloaded and installed the first step is to set up a secure connection between the Windows system and the remote Linux system with appropriate tunneling configured. When launched, PuTTY displays the following screen:. Enter the IP address or host name of the remote host or the external IP address of the gateway if you are connecting from outside the firewall.

The next step is to set up the tunnel. The screen should appear as follows:. Enter as the Source port and localhost as the Destination and click on Add. Finally return to the main screen by clicking on the Session category. Enter a name for the session in the Saved Sessions text field and press save.

Click on Open to establish the connection. A terminal window will appear with the login prompt from the remote system. Enter your user login and password credentials. The SSH connection is now established. The viewer will establish the connection, prompt for the password and then display the desktop. You are now accessing the remote desktop of a Linux system on Windows.

In the examples so far we have only covered remote access to the primary desktop. By primary desktop we mean the desktop you see when you sit at your computer and turn on the monitor. While this is fine for a single user system we should not lose sight of the fact that Linux is a multi-user operating system and it will often be necessary for more than one person to have remote desktop access at a time. While it might be fun to watch everyone fight over the mouse pointer as they share the same desktop it is clear that not much work will get done.

The solution to this is to run multiple desktops for the users to connect to. New desktop environments are created using the vncserver utility which should also have been installed by default when you installed RHEL. Installation may, however, be performed as follows:. The desktop we have used so far in this chapter is desktop New desktops must be assigned different numbers. For example to launch desktop :1 run the following command from a terminal window command-line prompt:. The vncserver tool will prompt for a password to protect the desktop and then start a new desktop in the background ready for a remote user to connect to.
