ansible flush handlers

In ansible playbooks, handlers (such as to restart a service) normally happen at the end of a run.
If you need ansible to run a handler between two tasks, there is “flush_handlers”.

Serial port console

This is how to get serial port console working on a Ubuntu 16.04 (or any systemd based OS) and how to access it with idrac/ssh.

To get serial port working on a running system:

systemctl enable [email protected]
systemctl start [email protected]

Update Grub:

To get serial console during boot up, including the grub menu:

Go ahead and edit /etc/default/grub

GRUB_TERMINAL="console serial"
# also, it takes so long to boot a server, adding 10
# second to the grub menu is more good than harm

Access it via idrac

ssh <idrac-ip> console com2


I browse pornhub for the articles. Not only is this an interesting article on the drop in traffic during the Hawaii Missile Alert, I also discovered that their insight’s blog has a lot of good data analysis type articles. The blog itself is SFW with no bad images, though of course the logo and items mentioned in the articles themselves would not be. #yourtech-dailies
