Ubuntu16/Windows2012/CentOS7 cheat-sheet (started 23 May 2016)

  1. VMWare tools prereq: yum install perl gcc make kernel-headers kernel-devel -y
  2. aborted yum transactions should be cleaned up: yum-complete-transaction –cleanup-only
  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 ¬¬):

    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.
