How to: Configure the management IP
Posted by Wouter Debie, Last modified by Dries Decock on 28 November 2023 12:05 PM

By default the ByteBlower-sever will use DHCP to get its management ip. In some lab-environments this is not wanted. This page explains you how you can configure a fixed-ip on the management interface.

All this configuration is done by using our ByteBlower-Configurator tool on the server.

Start the byteblower-configurator

Dismiss the welcome-screen

Select System Configuration

Select Network configuration

Select the management interface that you want to change. In most cases it will be Interface man0

In "Review the interface configuration" you can see its current configuration. We want to change this to a static ip. Select Connectivity to change the configuration

Provide all the needed information. IPv6 is optional

Everything is configured. Use the TAB-key to select <OK>. Select < Back > to go all the way back to the Main menu

Now save and exit
to apply the configuration

Now your server will have the configured IP-settings.

Expert Info: Releasing the DHCP unique identifier (DUID)

The DHCP server and client recognize each other based on the DUID. This value stays fixed across reboots and tends to ensure that the same devices get the same IP addresses each time. In rare occasions one might want to clear this association.

Clearing the DUID is a manual action and differs between ByteBlower systems. The type can be determined with lsb_release -a In case of doubt, do contact support.

On the Debian based systems, clearing is done as follows:

echo UNINITIALIZED > /var/lib/dbus/machine-id
echo UNINITIALIZED > /etc/machine-id

For the older, Excentux based systems, the following commands are required:

mkdir -p /tmp/images
mkdir -p /tmp/config
mount /dev/disk/by-label/IMAGES /tmp/images
mount /tmp/images/config.img /tmp/config
cd /tmp/config
rm dhcpcd*
