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. The VNC server has an index referred to as the Session or Display. Only one server can run on a given display. If the vncserver setup. To start the VNC desktop run the vncserver command. You will see a short message like the following from the vncserver before it goes into the. RESTART VNC SERVER PI

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. If the network interface serving the VNC sessions is protected by a firewall, you need to manually open the port used by your session in the firewall.

If starting multiple sessions you may alternatively open a range of ports. See Chapter 23, Masquerading and Firewalls for details on how to configure the firewall. For persistent sessions, the VNC display and the X display usually have the same number. To start a session with a resolution of x pixel and with a color depth of bit, enter the following command:. The vncserver command picks an unused display number when none is given and prints its choice.

See man 1 vncserver for more options. When running vncserver for the first time, it asks for a password for full access to the session. If needed, you can also provide a password for view-only access to the session. The password s you are providing here are also used for future sessions started by the same user. They can be changed with the vncpasswd command.

Make sure to use strong passwords of significant length eight or more characters. Do not share these passwords. To terminate the session shut down the desktop environment that runs inside the VNC session from the VNC viewer as you would shut it down if it was a regular local X session. If you prefer to manually terminate a session, open a shell on the VNC server and make sure you are logged in as the user that owns the VNC session you want to terminate.

Run the following command to terminate the session that runs on display :1 : vncserver -kill Persistent VNC sessions are configured in a single per-user configuration. Multiple sessions started by the same user will all use the same start-up and password files. After you enable the VNC session management as described in Procedure You will be presented with the login screen.

After you log in, the 'VNC' icon will appear in the system tray of your desktop environment. Click the icon to open the VNC Session window. If it does not appear or if your desktop environment does not support icons in the system tray, run vncmanager-controller manually. This is equivalent to an one-time session. It is not visible to others and will be terminated after you disconnect from it.

The session is visible to other users and keeps running even after you disconnect from it. Here you can specify the name of the persistent session so that it is easily identified when reconnecting. The session will be freely accessible without having to log in under user credentials. You need to log in with a valid user name and password to access the session.

Lists the valid user names in the Allowed users text box. This does not terminate your active VNC session. For Method 1 and Method 2, you must connect to a specific active session or display ID using one of two options:.

For example, if the display ID is 3, it can be specified as or just as 3. Use For simplicity, the instructions below use the fully-qualified VNC port number. The following screenshot shows connecting to Clear Linux OS host Follow these steps:. Right-click a connection node and select Properties…. See Figure 3.

For Method 3, only the system administrator can stop and disable the VNC service by using these commands:. By default, VNC traffic is not encrypted. This is accomplished by following these steps:. Configure the VNC server to only accept connection from localhost by adding the -localhost option.

Your client system will forward traffic from the localhost the client destined for a specified fully-qualified VNC port number on the client to your Clear Linux OS host with the same port number. It should look like this:. Edit the systemd service script vncserver :[X].

The example below uses vncserver No change is needed to the xvnc service script. After you have restarted your VNC session, you can verify that it only accepts connections from localhost by using the netstat command like this:. Add the Clear Linux OS network-basic bundle to get the netstat command. Figure 6 shows two VNC sessions and accepting connections from any host as specified by the 0.

This is before the -localhost option was used. Figure 7 shows two VNC sessions and only accepting connections from localhost as specified by This is after the -localhost option was used. Replace [client port number] with an available client port number for example: For simplicity, you can make the [client port number] the same as the [fully-qualified VNC port number].

In the Source port field, enter an available client port number for example: For simplicity, you can make the Source port the same as the fully-qualified VNC port number. In the Destination field, enter localhost: plus the fully-qualified VNC port number. Enter localhost and the fully-qualified VNC port number.
