9.1 Accessing VNC Consoles

If VNC services are configured on the server, you can access the VNC consoles screens in OES Remote Manager. The accessibility to the VNC consoles via OES Remote Manager for Linux is limited to user root; it is not available to user Admin. This form of remote administration is less secure that SSH; therefore, we recommend using this feature only in a secure environment (behind a firewall).

IMPORTANT:VNC access is disabled by default to prevent cross-site scripting. You must disable the HttpOnly setting in the /etc/opt/novell/httpstkd.conf file in order to enable the VNC console display. For information, see Section A.4, HttpOnly Command.

  1. If VNC services are not configured on the server, you can configure them as follows:

    1. In YaST, log in as the root user, then click Network Services > Remote Administration.

    2. On the Remote Administration page, select the following options:

      • Allow Remote Administration

      • Open Port in Firewall (default port is 5801)

    3. Click Finish.

    4. Restart the display manager by entering the following command at the command line:

      rcxdm restart

  2. Verify that pop-up blocking is disabled in your web browser.

  3. Log in to OES Remote Manager as the root user.

  4. Select Manage Linux > VNC Consoles.

  5. If VNC Consoles is disabled, a message is displayed instead of the console. You must disable the HttpOnly setting in the /etc/opt/novell/httpstkd.conf file in order to enable the VNC console display. For information, see Section A.4, HttpOnly Command.

  6. Click the 1024 X 728 button on the VNC Console Screens page.

Clicking the VNC Consoles link opens a Java applet in a secondary browser window. The following table explains what you can do from this window.
