| <h2 id="_description">DESCRIPTION</h2> |
| <div class="sectionbody"> |
| <div class="paragraph"> |
| <p>A really simple TCP Git daemon that normally listens on port "DEFAULT_GIT_PORT" |
| aka 9418. It waits for a connection asking for a service, and will serve |
| that service if it is enabled.</p> |
| </div> |
| <div class="paragraph"> |
| <p>It verifies that the directory has the magic file "git-daemon-export-ok", and |
| it will refuse to export any Git directory that hasn’t explicitly been marked |
| for export this way (unless the <code>--export-all</code> parameter is specified). If you |
| pass some directory paths as <em>git daemon</em> arguments, the offers are limited to |
| repositories within those directories.</p> |
| </div> |
| <div class="paragraph"> |
| <p>By default, only <code>upload-pack</code> service is enabled, which serves |
| <em>git fetch-pack</em> and <em>git ls-remote</em> clients, which are invoked |
| from <em>git fetch</em>, <em>git pull</em>, and <em>git clone</em>.</p> |
| </div> |
| <div class="paragraph"> |
| <p>This is ideally suited for read-only updates, i.e., pulling from |
| Git repositories.</p> |
| </div> |
| <div class="paragraph"> |
| <p>An <code>upload-archive</code> also exists to serve <em>git archive</em>.</p> |
| </div> |
| </div> |
| </div> |
| <div class="sect1"> |
| <h2 id="_options">OPTIONS</h2> |
| <div class="sectionbody"> |
| <div class="dlist"> |
| <dl> |
| <dt class="hdlist1">--strict-paths</dt> |
| <dd> |
| <p>Match paths exactly (i.e. don’t allow "/foo/repo" when the real path is |
| "/foo/repo.git" or "/foo/repo/.git") and don’t do user-relative paths. |
| <em>git daemon</em> will refuse to start when this option is enabled and no |
| directory arguments are provided.</p> |
| </dd> |
| <dt class="hdlist1">--base-path=<path></dt> |
| <dd> |
| <p>Remap all the path requests as relative to the given path. |
| This is sort of "Git root" - if you run <em>git daemon</em> with |
| <em>--base-path=/srv/git</em> on example.com, then if you later try to pull |
| <em>git://example.com/hello.git</em>, <em>git daemon</em> will interpret the path |
| as <code>/srv/git/hello.git</code>.</p> |
| </dd> |
| <dt class="hdlist1">--base-path-relaxed</dt> |
| <dd> |
| <p>If --base-path is enabled and repo lookup fails, with this option |
| <em>git daemon</em> will attempt to lookup without prefixing the base path. |
| This is useful for switching to --base-path usage, while still |
| allowing the old paths.</p> |
| </dd> |
| <dt class="hdlist1">--interpolated-path=<pathtemplate></dt> |
| <dd> |
| <p>To support virtual hosting, an interpolated path template can be |
| used to dynamically construct alternate paths. The template |
| supports %H for the target hostname as supplied by the client but |
| converted to all lowercase, %CH for the canonical hostname, |
| %IP for the server’s IP address, %P for the port number, |
| and %D for the absolute path of the named repository. |
| After interpolation, the path is validated against the directory |
| list.</p> |
| </dd> |
| <dt class="hdlist1">--export-all</dt> |
| <dd> |
| <p>Allow pulling from all directories that look like Git repositories |
| (have the <em>objects</em> and <em>refs</em> subdirectories), even if they |
| do not have the <em>git-daemon-export-ok</em> file.</p> |
| </dd> |
| <dt class="hdlist1">--inetd</dt> |
| <dd> |
| <p>Have the server run as an inetd service. Implies --syslog (may be |
| overridden with <code>--log-destination=</code>). |
| Incompatible with --detach, --port, --listen, --user and --group |
| options.</p> |
| </dd> |
| <dt class="hdlist1">--listen=<host-or-ipaddr></dt> |
| <dd> |
| <p>Listen on a specific IP address or hostname. IP addresses can |
| be either an IPv4 address or an IPv6 address if supported. If IPv6 |
| is not supported, then --listen=<hostname> is also not supported and |
| --listen must be given an IPv4 address. |
| Can be given more than once. |
| Incompatible with <code>--inetd</code> option.</p> |
| </dd> |
| <dt class="hdlist1">--port=<n></dt> |
| <dd> |
| <p>Listen on an alternative port. Incompatible with <code>--inetd</code> option.</p> |
| </dd> |
| <dt class="hdlist1">--init-timeout=<n></dt> |
| <dd> |
| <p>Timeout (in seconds) between the moment the connection is established |
| and the client request is received (typically a rather low value, since |
| that should be basically immediate).</p> |
| </dd> |
| <dt class="hdlist1">--timeout=<n></dt> |
| <dd> |
| <p>Timeout (in seconds) for specific client sub-requests. This includes |
| the time it takes for the server to process the sub-request and the |
| time spent waiting for the next client’s request.</p> |
| </dd> |
| <dt class="hdlist1">--max-connections=<n></dt> |
| <dd> |
| <p>Maximum number of concurrent clients, defaults to 32. Set it to |
| zero for no limit.</p> |
| </dd> |
| <dt class="hdlist1">--syslog</dt> |
| <dd> |
| <p>Short for <code>--log-destination=syslog</code>.</p> |
| </dd> |
| <dt class="hdlist1">--log-destination=<destination></dt> |
| <dd> |
| <p>Send log messages to the specified destination. |
| Note that this option does not imply --verbose, |
| thus by default only error conditions will be logged. |
| The <destination> must be one of:</p> |
| <div class="openblock"> |
| <div class="content"> |
| <div class="dlist"> |
| <dl> |
| <dt class="hdlist1">stderr</dt> |
| <dd> |
| <p>Write to standard error. |
| Note that if <code>--detach</code> is specified, |
| the process disconnects from the real standard error, |
| making this destination effectively equivalent to <code>none</code>.</p> |
| </dd> |
| <dt class="hdlist1">syslog</dt> |
| <dd> |
| <p>Write to syslog, using the <code>git-daemon</code> identifier.</p> |
| </dd> |
| <dt class="hdlist1">none</dt> |
| <dd> |
| <p>Disable all logging.</p> |
| </dd> |
| </dl> |
| </div> |
| </div> |
| </div> |
| <div class="paragraph"> |
| <p>The default destination is <code>syslog</code> if <code>--inetd</code> or <code>--detach</code> is specified, |
| otherwise <code>stderr</code>.</p> |
| </div> |
| </dd> |
| <dt class="hdlist1">--user-path</dt> |
| <dt class="hdlist1">--user-path=<path></dt> |
| <dd> |
| <p>Allow ~user notation to be used in requests. When |
| specified with no parameter, a request to |
| git://host/~alice/foo is taken as a request to access |
| <em>foo</em> repository in the home directory of user <code>alice</code>. |
| If <code>--user-path=</code><em><path></em> is specified, the same request is |
| taken as a request to access <em><path></em><code>/foo</code> repository in |
| the home directory of user <code>alice</code>.</p> |
| </dd> |
| <dt class="hdlist1">--verbose</dt> |
| <dd> |
| <p>Log details about the incoming connections and requested files.</p> |
| </dd> |
| <dt class="hdlist1">--reuseaddr</dt> |
| <dd> |
| <p>Use SO_REUSEADDR when binding the listening socket. |
| This allows the server to restart without waiting for |
| old connections to time out.</p> |
| </dd> |
| <dt class="hdlist1">--detach</dt> |
| <dd> |
| <p>Detach from the shell. Implies --syslog.</p> |
| </dd> |
| <dt class="hdlist1">--pid-file=<file></dt> |
| <dd> |
| <p>Save the process id in <em>file</em>. Ignored when the daemon |
| is run under <code>--inetd</code>.</p> |
| </dd> |
| <dt class="hdlist1">--user=<user></dt> |
| <dt class="hdlist1">--group=<group></dt> |
| <dd> |
| <p>Change daemon’s uid and gid before entering the service loop. |
| When only <code>--user</code> is given without <code>--group</code>, the |
| primary group ID for the user is used. The values of |
| the option are given to <code>getpwnam</code>(<code>3</code>) and <code>getgrnam</code>(<code>3</code>) |
| and numeric IDs are not supported.</p> |
| <div class="paragraph"> |
| <p>Giving these options is an error when used with <code>--inetd</code>; use |
| the facility of inet daemon to achieve the same before spawning |
| <em>git daemon</em> if needed.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Like many programs that switch user id, the daemon does not reset |
| environment variables such as <code>$HOME</code> when it runs git programs, |
| e.g. <code>upload-pack</code> and <code>receive-pack</code>. When using this option, you |
| may also want to set and export <code>HOME</code> to point at the home |
| directory of <em><user></em> before starting the daemon, and make sure any |
| Git configuration files in that directory are readable by <em><user></em>.</p> |

| <dt class="hdlist1">--[no-]informative-errors</dt> |
| <dd> |
| <p>When informative errors are turned on, git-daemon will report |
| more verbose errors to the client, differentiating conditions |
| like "no such repository" from "repository not exported". This |
| is more convenient for clients, but may leak information about |
| the existence of unexported repositories. When informative |
| errors are not enabled, all errors report "access denied" to the |
| client. The default is --no-informative-errors.</p> |

| path to the repository, hostname (%H), canonical hostname |
| (%CH), IP address (%IP), and TCP port (%P) as its command-line |
| arguments. The external command can decide to decline the |
| service by exiting with a non-zero status (or to allow it by |
| exiting with a zero status). It can also look at the $REMOTE_ADDR |
| and <code>$REMOTE_PORT</code> environment variables to learn about the |
| requestor when making this decision.</p> |
| <div class="paragraph"> |
| <p>The external command can optionally write a single line to its |

| it declines the service.</p> |

| serve a requested directory only if it is contained in one of |
| these directories. If <code>--strict-paths</code> is specified, then the |
| requested directory must match one of these directories exactly.</p> |
