       git-daemon - A really simple server for Git repositories


       git daemon [--verbose] [--syslog] [--export-all]
                    [--timeout=<n>] [--init-timeout=<n>] [--max-connections=<n>]

                     [--user=<user> [--group=<group>]]]


       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.

       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
       --export-all parameter is specified). If you pass some directory paths
       as git daemon arguments, the offers are limited to repositories within
       those directories.

       By default, only upload-pack service is enabled, which serves git
       fetch-pack and git ls-remote clients, which are invoked from git fetch,
       git pull, and git clone.

       This is ideally suited for read-only updates, i.e., pulling from Git

       An upload-archive also exists to serve git archive.


           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.  git daemon will refuse to start when this
           option is enabled and no directory arguments are provided.

           Remap all the path requests as relative to the given path. This is
           sort of "Git root" - if you run git daemon with
           --base-path=/srv/git on, then if you later try to pull
           git://, git daemon will interpret the path as

           If --base-path is enabled and repo lookup fails, with this option
           git daemon will attempt to lookup without prefixing the base path.
           This is useful for switching to --base-path usage, while still
           allowing the old paths.

           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.

           Allow pulling from all directories that look like Git repositories
           (have the objects and refs subdirectories), even if they do not
           have the git-daemon-export-ok file.

           Have the server run as an inetd service. Implies --syslog (may be
           overridden with --log-destination=). Incompatible with --detach,
           --port, --listen, --user and --group options.

           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 --inetd option.

           Listen on an alternative port. Incompatible with --inetd option.

           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).

           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

           Maximum number of concurrent clients, defaults to 32. Set it to
           zero for no limit.

           Short for --log-destination=syslog.

           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:

               Write to standard error. Note that if --detach is specified,
               the process disconnects from the real standard error, making
               this destination effectively equivalent to none.

               Write to syslog, using the git-daemon identifier.

               Disable all logging.

           The default destination is syslog if --inetd or --detach is
           specified, otherwise stderr.

       --user-path, --user-path=<path>
           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 foo repository in the home directory of user alice. If
           --user-path=<path> is specified, the same request is taken as a
           request to access <path>/foo repository in the home directory of
           user alice.

           Log details about the incoming connections and requested files.

           Use SO_REUSEADDR when binding the listening socket. This allows the
           server to restart without waiting for old connections to time out.

           Detach from the shell. Implies --syslog.

           Save the process id in file. Ignored when the daemon is run under

       --user=<user>, --group=<group>
           Change daemon's uid and gid before entering the service loop. When
           only --user is given without --group, the primary group ID for the
           user is used. The values of the option are given to getpwnam(3) and
           getgrnam(3) and numeric IDs are not supported.

           Giving these options is an error when used with --inetd; use the
           facility of inet daemon to achieve the same before spawning git
           daemon if needed.

           Like many programs that switch user id, the daemon does not reset
           environment variables such as $HOME when it runs git programs, e.g.
           upload-pack and receive-pack. When using this option, you may also
           want to set and export HOME to point at the home directory of
           <user> before starting the daemon, and make sure any Git
           configuration files in that directory are readable by <user>.

       --enable=<service>, --disable=<service>
           Enable/disable the service site-wide per default. Note that a
           service disabled site-wide can still be enabled per repository if
           it is marked overridable and the repository enables the service
           with a configuration item.

       --allow-override=<service>, --forbid-override=<service>
           Allow/forbid overriding the site-wide default with per repository
           configuration. By default, all the services may be overridden.

           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.

           Every time a client connects, first run an external command
           specified by the <path> with service name (e.g. "upload-pack"),
           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 $REMOTE_PORT environment
           variables to learn about the requestor when making this decision.

           The external command can optionally write a single line to its
           standard output to be sent to the requestor as an error message
           when it declines the service.

           The remaining arguments provide a list of directories. If any
           directories are specified, then the git-daemon process will serve a
           requested directory only if it is contained in one of these
           directories. If --strict-paths is specified, then the requested
           directory must match one of these directories exactly.


       These services can be globally enabled/disabled using the command-line
       options of this command. If finer-grained control is desired (e.g. to
       allow git archive to be run against only in a few selected repositories
       the daemon serves), the per-repository configuration file can be used
       to enable or disable them.

           This serves git fetch-pack and git ls-remote clients. It is enabled
           by default, but a repository can disable it by setting
           daemon.uploadpack configuration item to false.

           This serves git archive --remote. It is disabled by default, but a
           repository can enable it by setting daemon.uploadarch configuration
           item to true.

           This serves git send-pack clients, allowing anonymous push. It is
           disabled by default, as there is no authentication in the protocol
           (in other words, anybody can push anything into the repository,
           including removal of refs). This is solely meant for a closed LAN
           setting where everybody is friendly. This service can be enabled by
           setting daemon.receivepack configuration item to true.


       We assume the following in /etc/services

               $ grep 9418 /etc/services
               git             9418/tcp                # Git Version Control System

       git daemon as inetd server
           To set up git daemon as an inetd service that handles any
           repository within /pub/foo or /pub/bar, place an entry like the
           following into /etc/inetd all on one line:

                       git stream tcp nowait nobody  /usr/bin/git
                               git daemon --inetd --verbose --export-all
                               /pub/foo /pub/bar

       git daemon as inetd server for virtual hosts
           To set up git daemon as an inetd service that handles repositories
           for different virtual hosts, and,
           place an entry like the following into /etc/inetd all on one line:

                       git stream tcp nowait nobody /usr/bin/git
                               git daemon --inetd --verbose --export-all

           In this example, the root-level directory /pub will contain a
           subdirectory for each virtual host name supported. Further, both
           hosts advertise repositories simply as
           git:// For pre-1.4.0 clients, a
           symlink from /software into the appropriate default repository
           could be made as well.

       git daemon as regular daemon for virtual hosts
           To set up git daemon as a regular, non-inetd service that handles
           repositories for multiple virtual hosts based on their IP
           addresses, start the daemon like this:

                       git daemon --verbose --export-all

           In this example, the root-level directory /pub will contain a
           subdirectory for each virtual host IP address supported.
           Repositories can still be accessed by hostname though, assuming
           they correspond to these IP addresses.

       selectively enable/disable services per repository
           To enable git archive --remote and disable git fetch against a
           repository, have the following in the configuration file in the
           repository (that is the file config next to HEAD, refs and

                               uploadpack = false
                               uploadarch = true


       git daemon will set REMOTE_ADDR to the IP address of the client that
       connected to it, if the IP address is available. REMOTE_ADDR will be
       available in the environment of hooks called when services are
