  3. How to reboot headless server with passphrase? here there are 2 of the best ones I’ve managed to found so far (after spending lots of hours trying out multiple impossible configurations ¬¬):

    https://stinkyparkia.wordpress.com/2014/10/14/remote-unlocking-luks-encrypted-lvm-using-dropbear-ssh-in-ubuntu-server-14-04-1-with-static-ipst/

    https://github.com/chadoe/luks-triple-unlock/blob/master/install.sh

    After configuring the servers that way, one can decrypt the LUKS partition via SSH (using password or rsa-key) or an USB flash drive and let the system boot as usual. Quite useful in my case.

 

Ubuntu 16_04 64bit

  1. Static IP is not updated. Must restart server.

Windows 2012 R2 DC

  1. Firewall must be updated explicitly for the 3389 port to get remote desktop work.
