Network Managers

====================================================================================

Netplan uses .yaml files for network configuration, these are stored in /etc/netplan

Check DHCP IP leases info

netplan ip leases interfacename

Changes to interfaces are made in the .yaml files, once changes have been made they need to be applied.

To test changes, use the try command. This essentially implements the change for a set amount of time, after which the change is reverted.

netplan try

You can also set a custom timeout time using the below command:

netplan try --timeout=15

To permanently apply a change, use the below command:

netplan apply
