suse sles vnc server

SUSE Linux Enterprise Server supports two different kinds of VNC sessions: One-time sessions that “live” as long as the VNC connection from the client is. The SUSE Linux Enterprise Server (SLES) 11 SP 1 distribution provides not only a KDE4 graphical interface (KDE 4 version ), but also VNC server.

This application works on the same principle as the x0vncserver. Various configurations are possible depending on your use case. All following configuration use the xorg-xXvnc package, unless mentioned otherwise. If you have multiple X servers running on multiple virtual terminals, only the currently active one will be active over VNC.

This is limitation of X server. This command uses encryption and password protection by default. You must setup your password first. You can connect to it using VNC display number matching the X display number :0 for first session, :1 for second session, etc. Following configurations share their own sessions that are independent on the content of real screen. Unlimited amount of sessions can run at once.

Use case: When you want your personal permanent session that will last until you manually terminate it. If it doesn't exist, it will create default one, which will:. Xvnc will use encryption and password protection by default. See [Security]. The permanent session gets next free VNC display number assigned in above example it was You can use that to connect to it. Use case: When you want to allow users to connect, start their session by logging in and automatically terminate the session when they disconnect.

The sessions are spawned automatically and the individual users do not need to prepare anything advance. Since Leap The VNC server listens on display number Every connection gets new session assigned. Virtual Network Computing VNC enables you to access a remote computer via a graphical desktop, and run remote graphical applications. VNC is platform-independent and accesses the remote machine from any operating system.

A VNC server can offer both kinds of sessions simultaneously on different ports, but an open session cannot be converted from one type to the other. To connect to a VNC service provided by a server, a client is needed. The actual display or port number you specify in the VNC client must be the same as the display or port number picked by the vncserver command on the target machine. See Section By running vncviewer without specifying --listen or a host to connect to, it will show a window to ask for connection details.

Enter the host into the VNC server field like in Section The VNC protocol supports different kinds of encrypted connections, not to be confused with password authentication. Remmina is a modern and feature rich remote desktop client. To use Remmina, verify whether the remmina package is installed on your system, and install it if not.

Remember to install the VNC plug-in for Remmina as well:. The main application window shows the list of stored remote sessions. Here you can add and save a new remote session, quick-start a new session without saving it, start a previously saved session, or set Remmina's global preferences.

To add and save a new remote session, click in the top left of the main window. The Remote Desktop Preference window opens. Complete the fields that specify your newly added remote session profile. The most important are:. If the communication between the client and the remote server is not encrypted, activate Disable encryption , otherwise the connection fails. Confirm with Save. Your new profile will be listed in the main window.

You can either start a previously saved session, or quick-start a remote session without saving the connection details. To start a remote session quickly without adding and saving connection details, use the drop-down box and text box at the top of the main window. Remote sessions are opened in tabs of a separate window. Each tab hosts one session. To edit a saved remote session, right-click its name in Remmina's main window and select Edit.

Refer to Section To copy a saved remote session, right-click its name in Remmina's main window and select Copy. In the Remote Desktop Preference window, change the name of the profile, optionally adjust relevant options, and confirm with Save. To Delete a saved remote session, right-click its name in Remmina's main window and select Delete. Confirm with Yes in the next dialog. If you need to open a remote session from the command line or from a batch file without first opening the main application window, use the following syntax:.

Remmina's profile files are stored in the. To determine which profile file belongs to the session you want to open, run Remmina, click the session name in the main window, and read the path to the profile file in the window's status line at the bottom. While Remmina is not running, you can rename the profile file to a more reasonable file name, such as sle You can even copy the profile file to your custom directory and run it using the remmina -c command from there.

A one-time session is initiated by the remote client. It starts a graphical login screen on the server. This way you can choose the user which starts the session and, if supported by the login manager, the desktop environment.

When you terminate the client connection to such a VNC session, all applications started within that session will be terminated, too. One-time VNC sessions cannot be shared, but it is possible to have multiple sessions on a single host at the same time. Activate Enable access using a web browser if you plan to access the VNC session in a Web browser window. If necessary, also check Open Port in Firewall for example, when your network interface is configured to be in the External Zone.

If you have more than one network interface, restrict opening the firewall ports to a specific interface via Firewall Details. In case not all needed packages are available yet, you need to approve the installation of missing packages. YaST makes changes to the display manager settings.

You need to log out of your current graphical session and restart the display manager for the changes to take effect. The default configuration on SUSE Linux Enterprise Server serves sessions with a resolution of x pixels at a color depth of bit. Other configurations can be made available on different ports , see Section VNC display numbers and X display numbers are independent in one-time sessions.

A VNC display number is manually assigned to every configuration that the server supports :1 in the example above. Whenever a VNC session is initiated with one of the configurations, it automatically gets a free X display number.

By default, both the VNC client and server try to communicate securely via a self-signed SSL certificate, which is generated after installation. You can either use the default one, or replace it with your own.

When using the self-signed certificate, you need to confirm its signature before the first connection—both in the VNC viewer and the Web browser. You can skip this section, if you do not need or want to modify the default configuration. One-time VNC sessions are started via the systemd socket xvnc. By default it offers six configuration blocks: three for VNC viewers vnc1 to vnc3 , and three serving a JavaScript client vnchttpd1 to vnchttpd3.

By default only vnc1 and vnchttpd1 are active. For a list of options, see Xvnc --help. When adding custom configurations, make sure they are not using ports that are already in use by other configurations, other services, or existing persistent VNC sessions on the same host. When activating Remote Administration as described in Procedure If the network interface serving the VNC sessions is protected by a firewall, you need to manually open the respective ports when activating additional ports for VNC sessions.

See Chapter 23, Masquerading and Firewalls for instructions. A persistent session can be accessed from multiple clients simultaneously. This is ideal for demonstration purposes where one client has full access and all other clients have view-only access. Another use case are trainings where the trainer might need access to the trainee's desktop. This type of persistent VNC session is initiated on the server. The session and all applications started in this session run regardless of client connections until the session is terminated.

Access to persistent sessions is protected by two possible types of passwords:. Open a shell and make sure you are logged in as the user that should own the VNC session.

The method described below will work for display :0 for all users and will work when nobody is logged into the system. Using the method described below seems to avoid that issue as well. Warnings Using this method to access display :0 can create a security problem if the system you have connected to is not physically secure. Anyone that has access to the physical system can see what you are doing and take control of the keyboard and mouse.

If you lose your connection or disconnect without logging out then anyone at the physical system can take control while still logged in as you. Directly modifying the xorg. Therefor it is Very Important to make a backup copy of your xorg. Step 1 The following modifications need to be made to the file "xorg. You will need to be the "root" user to have rights to modify the file. Locate the section titled "Section "Module"" and add the following line: Load "vnc" 2. Locate the section titled "Section "Device"".

All of the following lines can be added including the comments so there is a reference to what each setting does. Option "usevnc" If this option is disabled no password is required for client connections.

The rfbauth option specifies the location of a password file to use for authenticating viewers. If enabled the first connection will remain active and the second will be denied. If disabled the original connection will be terminated and the new connection takes over. Option "dontdisconnect" View only session disallows input from viewers Option "viewonly" Enable these options to activate the http server.

This allows java-enabled web browsers to act as vnc viewers. The VNC server will look in "httpdir" for the Java class files to send to the viewer. Option "useraccept" Step 2 Create a password for an authenticated connection. Login or su as root. Run the following command to set the password to be used for VNC access: vncpasswd You will be asked to enter the password 2 times to confirm.

You will then be asked if you would like to enter a "Read Only" password. If you would like to setup a password that only allows the person connecting to view the screen and not have keyboard and mouse control then answer yes and enter a new password different than the first password used for full access otherwise answer no. To enable XDMCP and root user access for the default displaymanager gdm there are three files that will need to be modified. Most systems are setup behind an already existing firewall so running the firewall on this server or desktop system is not required.

If the firewall is needed then an exception for TCP port will need to be added to the "Allowed Services". Step 5 Restart the system or switch to runlevel 3 init 3 then back to runlevel 5 init 5 to restart all the graphics components. Additional notes for "Option "rfbport" """ listed above in the Section "Device" section of the xorg. If port is used, the person connecting will be viewing display :0 which is what is being displayed on the monitor physically connected to the system.

If someone is already logged in then the connecting user will see what is currently being displayed for the logged in user rather than the login screen. If the connecting user closes the VNC client without logging out first then the next user to connect will see the desktop in the same state it was left in unless some other user connects or there is a"real" user at the system. I mention this as a reminder not to leave the system logged in as the "root" user or some other user you would not want other people to have access to.

Published on Sep Number of Views: I noticed today that it's working again so I thought I should post some notes on how to to get it working. There are some official ref notes on the Net: Internet Docs but they still don't work for me.

Maybe they'll work for you, so it's worth a read. If you have any suspicions that you are short a few RPMs, here's what was installed by default in mine: Code:. User Type: 3-Advanced.

One is an example and one is just the jar file. It is up to you. Thank You,. Sorry for my total noob comments.
