 599 <h2 id="_description">DESCRIPTION</h2>
 600 <div class="sectionbody">
 601 <div class="paragraph"><p>A really simple TCP git daemon that normally listens on port "DEFAULT_GIT_PORT"
 602 aka 9418.  It waits for a connection asking for a service, and will serve
 603 that service if it is enabled.</p></div>
 604 <div class="paragraph"><p>It verifies that the directory has the magic file "git-daemon-export-ok", and
 605 it will refuse to export any git directory that hasn&#8217;t explicitly been marked
 606 for export this way (unless the <em>--export-all</em> parameter is specified). If you
 607 pass some directory paths as <em>git daemon</em> arguments, you can further restrict
 608 the offers to a whitelist comprising of those.</p></div>
 609 <div class="paragraph"><p>By default, only <tt>upload-pack</tt> service is enabled, which serves
 610 <em>git fetch-pack</em> and <em>git ls-remote</em> clients, which are invoked
 611 from <em>git fetch</em>, <em>git pull</em>, and <em>git clone</em>.</p></div>
 612 <div class="paragraph"><p>This is ideally suited for read-only updates, i.e., pulling from
 613 git repositories.</p></div>
 614 <div class="paragraph"><p>An <tt>upload-archive</tt> also exists to serve <em>git archive</em>.</p></div>

 620 --strict-paths

 622 <dd>
 623 <p>
 624         Match paths exactly (i.e. don&#8217;t allow "/foo/repo" when the real path is
 625         "/foo/repo.git" or "/foo/repo/.git") and don&#8217;t do user-relative paths.
 626         <em>git daemon</em> will refuse to start when this option is enabled and no
 627         whitelist is specified.

 630 <dt class="hdlist1">
 631 --base-path=&lt;path&gt;

 633 <dd>
 634 <p>
 635         Remap all the path requests as relative to the given path.
 636         This is sort of "GIT root" - if you run <em>git daemon</em> with
 637         <em>--base-path=/srv/git</em> on example.com, then if you later try to pull
 638         <em>git://example.com/hello.git</em>, <em>git daemon</em> will interpret the path
 639         as <em>/srv/git/hello.git</em>.

 641 </dd>
 642 <dt class="hdlist1">
 643 --base-path-relaxed
 644 </dt>
 645 <dd>
 646 <p>
 647         If --base-path is enabled and repo lookup fails, with this option
 648         <em>git daemon</em> will attempt to lookup without prefixing the base path.
 649         This is useful for switching to --base-path usage, while still
 650         allowing the old paths.

 653 <dt class="hdlist1">
 654 --interpolated-path=&lt;pathtemplate&gt;
 655 </dt>
 656 <dd>
 657 <p>
 658         To support virtual hosting, an interpolated path template can be
 659         used to dynamically construct alternate paths.  The template
 660         supports %H for the target hostname as supplied by the client but
 661         converted to all lowercase, %CH for the canonical hostname,
 662         %IP for the server&#8217;s IP address, %P for the port number,
 663         and %D for the absolute path of the named repository.
 664         After interpolation, the path is validated against the directory
 665         whitelist.

 694         be either an IPv4 address or an IPv6 address if supported.  If IPv6
 695         is not supported, then --listen=hostname is also not supported and
