Scroll down to port tcp and click on OK. Repeat the previous stop for port udp. Click on the Apply button located in the toolbar and exit the firewall tool. Remote desktop access from other Linux based systems can be achieved using the vncviewer tool.
This tool is contained within a package named vnc which may be installed on RHEL using the following command sequence in a terminal window:. The vncviewer tool is available for a wide range of operating systems and a quick internet search will likely provide numerous links providing details on how to obtain and install this tool on your chosen platform. Alternatively, run the command without any options to be prompted for the details of the remote server:.
If you configured the remote system to prompt to approve a connection a dialog will appear on the remote system. Until the connection is approved the vncviewer session will wait. Once approved, or if no approval is required, VNC will prompt for the password assuming one was defined :. If you see a message similar to the following then you may need to use the secure method of remote desktop display outlined in the next section:.
Otherwise, enter the password and a new screen will appear containing the desktop from the remote system. Note that if the remote desktop is configured to prompt you before allowing remote access you will need to accept the connection on the remote system before the desktop will appear in the viewer. If remote desktop control was enabled you can interact with the desktop as if you were sitting at the remote screen.
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. You would have to list the contents of those RPM's to see where it has placed the configuration files. If you don't know how something in a program works, the manual page is usually a good place to start learning ;- Features may vary between VNC servers, and they may be suited to specific tasks, but they all do essentially the same thing.
