6 Service Configuration: Administration Server Network Configuration #

Start YaST › System › Network Settings.

Switch to the Overview tab, select the interface with the Device identifier, eth0 and choose Edit.

Switch to the Address tab and activate Statically Assigned IP Address. Provide an IPv4 IP Address, a Subnet Mask, and a fully qualified Hostname. Examples in this book assume the default IP address of 192.168.124.10 and a network mask of 255.255.255.0. Using a different IP address requires adjusting the Crowbar configuration in a later step as described in Chapter 7, Crowbar Setup.

Check the settings on the General tab. The device needs to be activated At Boot Time. Confirm your settings with Next.

Back on the Network Settings dialog, switch to the Routing tab and enter a Default IPv4 Gateway. The address depends on whether you have provided an external gateway for the admin network. In that case, use the address of that gateway. If not, use xxx.xxx.xxx.1, for example, 192.168.124.1. Confirm your settings with OK.

Choose Hostname/DNS from the Network Settings dialog and set the Hostname and Domain Name. Examples in this book assume admin.cloud.example.com for the host/domain name.

If the Administration Server has access to the outside, you can add additional name servers here that will automatically be used to forward requests. The Administration Server's name server will automatically be configured during the SUSE OpenStack Cloud Crowbar installation to forward requests for non-local records to those server(s).

Last, check if the firewall is disabled. Return to YaST's main menu (YaST Control Center) and start Security and Users › Firewall. On Start-Up › Service Start, the firewall needs to be disabled. Confirm your settings with Next.
