Introduction

I'm working with Ansible and many of servers every day, so let me show you, how can waste less of your time! :)

What Ansible do?

Connects, runs, check, sends back, processes it, runs, checks, sends back and voila!
Connects... again... and again... and again...

What you can do to fix on node/remote server

Edit sshd config and disable UseDNS, it's mainly used only for logging and authentication. But.. only when you have set IgnoreRhosts in your config. So who doesn't know, should use it with clean mind. Because this has truly so far with security. :)

Get list of system apps on the device:

adb shell "echo 'apps:' && pm list packages -f | grep /system/app/ | sed 's/.*=/  - /'"

Remove application command

pm uninstall -k --user 0 app
