Use PuTTY to manage the Red Hat Using SSH in the graphic environment

By default, installing Red Hat Enterprise Linux (RHEL) provides a text Console where you should work. Experienced Linux administrators like this method because the command line provides sufficient flexibility and direct access to all options of all commands. However, it is not just a command line, but a graphical option can also be used to manage the Red Hat Enterprise Linux.

Before you start, there is a memo: although some graphic tools provide many options, they still provide no command line options. However, as long as you do not need to go deep into the system, these graphic tools are enough.

Obtain graphic access

There are different ways to access a graphic desktop. First, you have to make a basic choice: Do you want to install a fully sophisticated graphic desktop? If so, make sure that the graphic desktop mode is installed when you install the Red Hat Enterprise-level Linux server, or you can add it later, the command used in this process is yum-y groupinstall "GNOME Desktop Environment ". In some cases, you may not want to run a fully sophisticated graphic desktop on your server (to save system resources ).

To run a complete GNOME graphic environment, you should have at least MB of available random memory (RAM ).

Another way is to make sure that the required tools are installed and can be remotely accessed through an SSH connection. On a Linux desktop, you can use the ssh-X command to open a graphical connection to your server. If you are running Windows, you will need PuTTY and an X-client, such as Xming. After these are installed, you can open a connection to the server and run the graphic application program there.

To configure PuTTY on Windows to send graph sessions, you must first ensure that PuTTY and Xming have been installed on your Windows computer. PuTTY is responsible for processing SSH connections, while Xming ensures that your Windows computer displays graphical sessions from Linux servers. After the two are installed, make sure that Xming is in the starting state. Open PuTTY and choose Connection> SSH> X11. Make sure that Enable X11 Forwarding is selected and enter localhost at X Display Location.

After configuring PuTTY to send a graph session, save your settings. Select Sessions and enter the server name and IP address. (make sure that the SSH process is listening for port 22 or change the default port address ). Next, click Save to Save your settings.

At this time, you have configured PuTTY to receive the graphical interface from your server. To perform the test, open a session from PuTTY to your server and run the system configuration language (system-config-language) command. The graphic interface allows you to change the language settings. All these highlights are:The program runs on your server, but the screen is displayed on your desktop..
