DHCP fallback address

["Bruno L. Albrecht" <brunolalb gmail com>]

Hello all,

I've been struggling with some configuration here and hope you could give me a hint.

Currently using 

• Ubuntu 18.04,
• kernel 4.15.0-43-generic,
• NetworkManager version 1.10.6,
• dhclient version isc-dhclient-4.3.5

Installed Ubuntu in a virtual machine (Virtual Box) and edited the network connections to have a Host only adapter, disabled the DHCP on VirtualBox.

My objective: to configure the DHCP client's fallback address and timeout.

What I did: edited the /etc/dhcp/dhclient.conf to contain a lease option for the mentioned network adapter with a specific IP address.

I attached a few files:

• dhclient.conf
  
• dhclient-enp0s8.conf (check lines 42-43, where the lease should end)
  
• journalctl.txt (output of "journalctl -u NetworkManager" after stopping the dhclient app and restarting the NetworkManager service)

Seems like the NetworkManager is incorrectly overwriting the dhclient.

Any other info I should send?

Best regards and happy 2019!

Bruno
