Adding Exceptions on the Firewall

Adding Exceptions on the Firewall

If you cannot log in to the server through the graphical client tool, such as VNC, it may because the firewall function is enabled and no exception is added on the firewall.


  1. Log in to the server through the iBMC port as the root user. Right-click the desktop and choose Open in Terminal from the shortcut menu to access the CLI.

    To use the PuTTY to remotely log in to the server, you must enable root remote access. For details, see How to Enable or Disable Root Remote Connection.

  2. Run the rcSuSEfirewall2 status command to check the firewall status.

    unused indicates that the firewall is disabled, and running indicates that the firewall is enabled.
    LogServer:~ # rcSuSEfirewall2 status
    Checking the status of SuSEfirewall2                                                running

  3. Run the rcSuSEfirewall2 stop command to disable the firewall temporarily.


    This command only disables the firewall but does not change its self-running status. Therefore, you need to further change its self-running status.

    LogServer:~ # rcSuSEfirewall2 stop
    Shutting down the Firewall                                                          done

    After you disable the firewall, you can run the check command to verify whether the firewall is disabled.

  4. Add exceptions on the firewall, and then restart the firewall.

    1. Choose Computer > YaST.
    2. Select Firewall under Security and Users.
    3. Click the Allowed Services tab and add exceptions, such as VNC, VNC Server.

    Select Enable Firewall Automatic Starting on the Start-Up tab and click Save Settings and Restart Firewall Now.
