GuideLike many linuxjournal readers, I have also lived in today's very popular "tech nomads" life, between networks, from one access point to another, where we are in different parts of the real world and remain connected to the Internet and other networks we use on a daily basis. Recently I have found that more and more network environments are starting to block common ports such as SMTP (port), SSH (Port 22), and so on.

The Rosinstall_generator can installed via a Debian package from the ROS repositories:
sudo apt-get update
sudo apt-get install Python-rosinstall-generator
For other platforms (where the Debian package isn't available) it can be installed from PyPI using PIP:
sudo pip

There used to be a lot of users asking us how to build Docker engine and related Debian packages. Maybe they want to try some new features, so they need to get the latest release version as soon as possible.
Here I share how to build the latest Docker version on Raspberry Pi. But note that although it is not very difficult but time-consuming.
So let's start, follow me into the Rabbit cave to explore (_ Tr
