Configure network interfaces

Configure the first interface as the management interface:

IP address: 10.0.0.11

Network mask: 255.255.255.0 (or /24)

Default gateway: 10.0.0.1
The provider interface uses a special configuration without an IP address assigned to it. Configure the second interface as the provider interface:

Replace INTERFACE_NAME with the actual interface name. For example, eth1 or ens224.

For Ubuntu:
- Edit the /etc/network/interfaces file to contain the following:
```
# The provider network interface
auto INTERFACE_NAME
iface INTERFACE_NAME inet manual
up ip link set dev $IFACE up
down ip link set dev $IFACE down
```
For RHEL or CentOS:
- Edit the /etc/sysconfig/network-scripts/ifcfg-INTERFACE_NAME file to contain the following:
  
  Do not change the HWADDR and UUID keys.
```
DEVICE=INTERFACE_NAME
TYPE=Ethernet
ONBOOT="yes"
BOOTPROTO="none"
```
For SUSE:
- Edit the /etc/sysconfig/network/ifcfg-INTERFACE_NAME file to contain the following:
```
STARTMODE='auto'
BOOTPROTO='static'
```
Reboot the system to activate the changes.

Set the hostname of the node to controller.
