Remove / Uninstall packages marked ‘rc’ on Debian / Ubuntu.

While checking the status of packages using dpkg, it is possible to see a ‘rc’ state for some unused packages, this corresponds to:

• r: the package was marked for removal
• c: the configuration files are currently present in the system

In other words: the package is not completely removed (config files are still present), but not installed anymore (and obviously not used).

To see a list of packages marked as ‘rc’:

Setting up Qemu with a tap interface

There are two parts to networking within QEMU:

• The virtual network device that is provided to the guest (e.g. a PCI network card).
• The network backend that interacts with the emulated NIC (e.g. puts packets onto the host's network).

Example: User mode network

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. :)
