OP makes an argument about what should be the sensible default in 2022, and who should do explicit configuration.&lt;p&gt;I think the point that nowadays easy single user linux configuration should be preferred over multi-user configurations is good.&lt;p&gt;IMO distros could make this easy by turning privileged ports into an (advanced) installation question. Then the clearly single-user-focused distros would default to 80, and the more server-oriented or conservative distros would default to the current behavior, but both could do which ever.&lt;p&gt;&amp;gt; Start your service on port 8080, for example.&lt;p&gt;In the era of Let&amp;#x27;s Encrypt, this is really about 80 and 443. The background for the OP is probably to host &amp;quot;normal&amp;quot; sites on single user hardware.&lt;p&gt;If you were to give out to non-technical users addresses like &amp;quot;&lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;example.org:8080&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;example.org:8080&lt;/a&gt;&amp;quot; which then transform into &amp;quot;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;example.org:8443&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;example.org:8443&lt;/a&gt;&amp;quot;, that&amp;#x27;s just horrible UX. Those kinds of numbers in the URL probably also look to many people like someone is trying to hack them. Furthermore addresses are also communicated word-of-mouth &amp;quot;go to example dot org&amp;quot;.&lt;p&gt;So no, using unprivileged ports is not an actual workaround for the use cases OP is referring to.</text><parent_chain><item><author>antimeme</author><text>This article is nonsense.  Privileged ports are a security feature.  They have literally nothing to do with mainframes.  On multi-user systems, they&amp;#x27;re incredibly important because they give external clients confidence that the services provided on them are authorized by the system and not just by any user -- some of whom may not be as trustworthy as others.  Most systems in this era of cheap hardware are single user, BUT NOT ALL SYSTEMS.  It&amp;#x27;s fine for Windows and Mac OS to do without them and it&amp;#x27;s fine to configure your own Linux system to disable them if that&amp;#x27;s what you want, but it&amp;#x27;s completely insane to argue that they&amp;#x27;re a security flaw because some people work around them using insecure practices.  There are plenty of secure ways to work around them, most obviously by USING A NON-PRIVILEGED PORT.  Start your service on port 8080, for example, and give out a URL like &lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;example.com:8080&amp;#x2F;path&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;example.com:8080&amp;#x2F;path&lt;/a&gt;.  It&amp;#x27;s really that simple.  Take the time to understand the actual purpose of a feature before urging others to abolish it.</text></item></parent_chain></comment><story><title>Dear Linux, Privileged Ports Must Die</title><url>https://ar.al/2022/08/30/dear-linux-privileged-ports-must-die/</url></story>

It just doesn&amp;#x27;t make sense to have this as the default anymore, as it tends to cause more security issues that it prevents.</text><parent_chain><item><author>antimeme</author><text>This article is nonsense.
