 431 <h2 id="_description">DESCRIPTION</h2>
 432 <div class="sectionbody">
 433 <div class="paragraph"><p>A really simple TCP git daemon that normally listens on port "DEFAULT_GIT_PORT"
 434 aka 9418.  It waits for a connection asking for a service, and will serve
 435 that service if it is enabled.</p></div>
 436 <div class="paragraph"><p>It verifies that the directory has the magic file "git-daemon-export-ok", and
 437 it will refuse to export any git directory that hasn&#8217;t explicitly been marked
 438 for export this way (unless the <em>--export-all</em> parameter is specified). If you
 439 pass some directory paths as <em>git daemon</em> arguments, you can further restrict
 440 the offers to a whitelist comprising of those.</p></div>
 441 <div class="paragraph"><p>By default, only <tt>upload-pack</tt> service is enabled, which serves
 442 <em>git fetch-pack</em> and <em>git ls-remote</em> clients, which are invoked
 443 from <em>git fetch</em>, <em>git pull</em>, and <em>git clone</em>.</p></div>
 444 <div class="paragraph"><p>This is ideally suited for read-only updates, i.e., pulling from
 445 git repositories.</p></div>
 446 <div class="paragraph"><p>An <tt>upload-archive</tt> also exists to serve <em>git archive</em>.</p></div>
 447 </div>
 448 <h2 id="_options">OPTIONS</h2>
 449 <div class="sectionbody">
 450 <div class="dlist"><dl>
 451 <dt class="hdlist1">
 452 --strict-paths
 453 </dt>
 454 <dd>
 455 <p>
 456         Match paths exactly (i.e. don&#8217;t allow "/foo/repo" when the real path is
 457         "/foo/repo.git" or "/foo/repo/.git") and don&#8217;t do user-relative paths.
 458         <em>git daemon</em> will refuse to start when this option is enabled and no
 459         whitelist is specified.
 460 </p>
 461 </dd>
 462 <dt class="hdlist1">
 463 --base-path=&lt;path&gt;
 464 </dt>
 465 <dd>
 466 <p>
 467         Remap all the path requests as relative to the given path.
 468         This is sort of "GIT root" - if you run <em>git daemon</em> with
 469         <em>--base-path=/srv/git</em> on example.com, then if you later try to pull
 470         <em>git://example.com/hello.git</em>, <em>git daemon</em> will interpret the path
 471         as <em>/srv/git/hello.git</em>.
 472 </p>
 473 </dd>
 474 <dt class="hdlist1">
 475 --base-path-relaxed
 476 </dt>
 477 <dd>
 478 <p>
 479         If --base-path is enabled and repo lookup fails, with this option
 480         <em>git daemon</em> will attempt to lookup without prefixing the base path.
 481         This is useful for switching to --base-path usage, while still
 482         allowing the old paths.
 483 </p>
 484 </dd>
 485 <dt class="hdlist1">
 486 --interpolated-path=&lt;pathtemplate&gt;
 487 </dt>
 488 <dd>
 489 <p>
 490         To support virtual hosting, an interpolated path template can be
 491         used to dynamically construct alternate paths.  The template
 492         supports %H for the target hostname as supplied by the client but
 493         converted to all lowercase, %CH for the canonical hostname,
 494         %IP for the server&#8217;s IP address, %P for the port number,
 495         and %D for the absolute path of the named repository.
 496         After interpolation, the path is validated against the directory
 497         whitelist.
 498 </p>
 499 </dd>
 500 <dt class="hdlist1">
 501 --export-all
 502 </dt>
 503 <dd>
 504 <p>
 505         Allow pulling from all directories that look like GIT repositories
 506         (have the <em>objects</em> and <em>refs</em> subdirectories), even if they
 507         do not have the <em>git-daemon-export-ok</em> file.

 526         be either an IPv4 address or an IPv6 address if supported.  If IPv6
 527         is not supported, then --listen=hostname is also not supported and
 528         --listen must be given an IPv4 address.
