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 -- Eng. Bruno Landau Albrecht e-mail/G-Talk: brunol...@gmail.com http://hardwaresw.blogspot.com.br/
