Generally all are automated processing of some life problems, data collection and related activities. So generally no client access to home server needs. But many times brain suddenly has ideas. Some small ideas, some small bugs or small optimizations, after code modification completes, there&rsquo;s a deployment need. Because home server doesn&rsquo;t have a stable external network IP, external network cannot directly connect to server. So we need <code>internal network penetration</code>.</p>https://time-friend.com/en/archive/network-notes-network-protocols-and-network-layering/Thu, 30 Aug 2018 00:00:00 +0000https://time-friend.com/en/archive/network-notes-network-protocols-and-network-layering/<p>The Bible has a Tower of Babel story, God to prevent humans from uniting, made humans speak different languages. Humans couldn&rsquo;t communicate, couldn&rsquo;t reach &ldquo;agreement&rdquo;, Tower of Babel plan failed.</p> <p>A thousand years later, a group of engineers to solve this problem, formulated various protocols and standards, let various devices communicate through protocols, then through internet achieved world interconnection.</p> <p>Like the code we write now, using universal programming languages, world is thus connected. Our computer languages are also a kind of protocol.</p>
