DESCRIPTION
       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, you can further restrict the offers to a
       whitelist comprising of those.

       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
       repositories.

       An upload-archive also exists to serve git archive.

OPTIONS
       --strict-paths
           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 whitelist is specified.

       --base-path=path
           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 example.com, then if you later try to pull
           git://example.com/hello.git, git daemon will interpret the path as
           /srv/git/hello.git.

       --base-path-relaxed
           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.

       --interpolated-path=pathtemplate
           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 whitelist.

       --export-all
           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.

       --inetd
           Have the server run as an inetd service. Implies --syslog.
           Incompatible with --port, --listen, --user and --group options.

       --listen=host_or_ipaddr
           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. Incompatible with --inetd
           option.

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

       --init-timeout=n
           Timeout 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=n
           Timeout 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.

       --max-connections=n
           Maximum number of concurrent clients, defaults to 32. Set it to
           zero for no limit.

       --syslog
           Log to syslog instead of stderr. Note that this option does not
           imply --verbose, thus by default only error conditions will be
           logged.

       --user-path, --user-path=path
           Allow ~user notation to be used in requests. When specified with no
           parameter, requests 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.

       --verbose
           Log details about the incoming connections and requested files.

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

       --detach
           Detach from the shell. Implies --syslog.

       --pid-file=file
           Save the process id in file. Ignored when the daemon is run under
           --inetd.

       --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.

       --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 are overridable.

       <directory>
           A directory to add to the whitelist of allowed directories. Unless
           --strict-paths is specified this will also include subdirectories
           of each named directory.

SERVICES
       These services can be globally enabled/disabled using the command line
       options of this command. If a 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.

       upload-pack
           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.

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

       receive-pack
           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
           daemon.receivepack configuration item to true.

EXAMPLES
       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 under the whitelisted set of directories, /pub/foo and
           /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, www.example.com and www.example.org,
           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
                               --interpolated-path=/pub/%H%D
                               /pub/www.example.org/software
                               /pub/www.example.com/software
                               /software

           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://www.example.com/software/repo.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
                               --interpolated-path=/pub/%IP/%D
                               /pub/192.168.1.200/software
                               /pub/10.10.220.23/software

           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
           objects).

                       [daemon]
                               uploadpack = false
                               uploadarch = true


ENVIRONMENT
       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
       performed.
