Configuring Network Boot Listener

The OS Deployment node is the central entry point for the deployment of operating systems to the devices within your network. With this functionality you can install completely new devices with an empty hard disk, you can reinstall existing devices with new operating systems or repair existing systems.

A network boot listener node has only Configuration subnode. The following topic guides you through the network boot listener configurations.

Configuration node of network boot listener

The Configuration node allows you to configure specific aspects of the network boot listener. The following parameters are available:


Parameter

Description

OSD Role

The type of OSD role the device is assigned to. This may be either Image Repository , Network Boot Listener or Image Repository and Network Boot Listener , if the OSD agent executes both roles.

Internal DHCP

Check this box if you want to use the DHCP gateway of the OSD module instead of specifically configuring your own DHCP server. In this case a DHCP gateway is installed that is redirecting the computers to the OSD manager and get installed, instead of adding the necessary options to your existing DHCP server. If you do not use this option make sure you have a DHCP server on a different machine that is configured as explained in the configuration options of the Prerequisites topic, preferably with the 066/067 options.

DHCP Server Address

The IP address or DNS name of the DHCP server which redirects the PXE requests to the local TFTP server. The DHCP server must have the protocol BOOTP activated.

Skip DHCP Check

If the DHCP server is installed on the same device as the OSD Manager device you must check this box, as the DHCP server cannot be verified in this case. This test verifies if the BOOTP protocol is activated on the DHCP server.

Unicast Server Port (TCP)

This parameter determines on which port the unicast server should listen and to which port the clients should send their requests and acknowledgements. It is only available in the general configuration, not on project level. Modifying this parameters requires restarting the unicast server and, to be correctly applied, restarting all related OSD agents as well. In addition all projects need to be rebuilt if this parameter is modified as it is embedded during the WinPE ISO image build. The default would be the agent port in TCP, typically 1613.

Multicast Server Port (UDP)

This parameter determines on which port the multicast server should listen and to which port the clients should send their requests and acknowledgements. It is only available in the general configuration, not on project level. Modifying this parameters requires restarting the multicast server and, to be correctly applied, restarting all related OSD agents as well. In addition all projects need to be rebuilt if this parameter is modified as it is embedded during the WinPE ISO image build. The default would be the agent port in UDP, typically 1610.

Network Interfaces

Defines on which local interfaces the agent listens. This can be either all interfaces or some specific ones.

To configure or modify Network Boot Listeners

To configure or modify the configuration of a network boot listener proceed as follows:

  1. Select the Configuration node of the network boot listener to modify in the left window pane.
  2. Select Edit> Properties.
    The Properties window appears.
  3. Make the desired changes in the respective boxes:

    Parameter

    Description

    Internal DHCP

    Check this box if you want to use the DHCP gateway of the OSD module instead of specifically configuring your own DHCP server. In this case a DHCP gateway is installed that is redirecting the computers to the OSD manager and get installed, instead of adding the necessary options to your existing DHCP server.If you do not use this option make sure you have a DHCP server on a different machine that is configured as explained in the configuration options of the Prerequisites topic, preferably with the 066/067 options. If you clear this box, the following two boxes become available.

    DHCP Server Address

    Enter the IP address or DNS name of the DHCP server which redirects the PXE requests to the local TFTP server. The DHCP server must have the protocol BOOTP activated.This option is only available if the internal DHCP gateway is not used.

    Skip DHCP Check

    If the DHCP server is installed on the same device as the OSD Manager device you must check this text box, because the DHCP server cannot be verified in this case. This test verifies if the BOOTP protocol is activated on the DHCP server.This option is only available if the internal DHCP gateway is not used.

    Unicast Server Port (TCP)

    This parameter determines on which port the unicast server should listen and to which port the clients should send their requests and acknowledgements. It is only available in the general configuration, not on project level. Modifying this parameters requires restarting the unicast server and, to be correctly applied, restarting all related OSD agents as well. In addition all projects need to be rebuilt if this parameter is modified as it is embedded during the WinPE ISO image build. The default would be the agent port in TCP, typically 1613. Only modify this default value if absolutely necessary.

    Multicast Server Port (UDP)

    This parameter determines on which port the multicast server should listen and to which port the clients should send their requests and acknowledgements. It is only available in the general configuration, not on project level. Modifying this parameters requires restarting the multicast server and, to be correctly applied, restarting all related OSD agents as well. In addition all projects need to be rebuilt if this parameter is modified as it is embedded during the WinPE ISO image build. The default would be the agent port in UDP, typically 1610. Only modify this default value if absolutely necessary.

    Interfaces

    For the Interfaces you need to define on which local interfaces the agent is to listen. You have the following options: All Interfaces: Check this radio button to listen on all local network interfaces. Custom Interfaces: CCheck this radio button to only listen on some local network interfaces. The box below displays the list of available interfaces. Check the boxes of all interfaces to listen to.

  4. (Optional) Click Create New Test Project to test your new settings via a test deployment.
  5. Click OK to confirm the changes and close the window.

Any changes made were saved and applied to the selected network boot listener.
