  21DESCRIPTION
  22-----------
  23A really simple TCP git daemon that normally listens on port "DEFAULT_GIT_PORT"
  24aka 9418.  It waits for a connection asking for a service, and will serve
  25that service if it is enabled.
  26
  27It verifies that the directory has the magic file "git-daemon-export-ok", and
  28it will refuse to export any git directory that hasn't explicitly been marked
  29for export this way (unless the '--export-all' parameter is specified). If you
  30pass some directory paths as 'git-daemon' arguments, you can further restrict
  31the offers to a whitelist comprising of those.
  32
  33By default, only `upload-pack` service is enabled, which serves
  34`git-fetch-pack` and `git-peek-remote` clients that are invoked
  35from `git-fetch`, `git-ls-remote`, and `git-clone`.
  36
  37This is ideally suited for read-only updates, i.e., pulling from
  38git repositories.
  39
  40An `upload-archive` also exists to serve `git-archive`.
  41
  42OPTIONS
  43-------
  44--strict-paths::
  45        Match paths exactly (i.e. don't allow "/foo/repo" when the real path is
  46        "/foo/repo.git" or "/foo/repo/.git") and don't do user-relative paths.
  47        git-daemon will refuse to start when this option is enabled and no
  48        whitelist is specified.
  49
  50--base-path::
  51        Remap all the path requests as relative to the given path.
  52        This is sort of "GIT root" - if you run git-daemon with
  53        '--base-path=/srv/git' on example.com, then if you later try to pull
  54        'git://example.com/hello.git', `git-daemon` will interpret the path
  55        as '/srv/git/hello.git'.
  56
  57--interpolated-path=pathtemplate::
  58        To support virtual hosting, an interpolated path template can be
  59        used to dynamically construct alternate paths.  The template
  60        supports %H for the target hostname as supplied by the client but
  61        converted to all lowercase, %CH for the canonical hostname,
  62        %IP for the server's IP address, %P for the port number,
  63        and %D for the absolute path of the named repository.
  64        After interpolation, the path is validated against the directory
  65        whitelist.
  66
  67--export-all::
  68        Allow pulling from all directories that look like GIT repositories
  69        (have the 'objects' and 'refs' subdirectories), even if they
  70        do not have the 'git-daemon-export-ok' file.
  71
  72--inetd::
  73        Have the server run as an inetd service. Implies --syslog.
  74        Incompatible with --port, --listen, --user and --group options.
  75
  76--listen=host_or_ipaddr::
  77        Listen on an a specific IP address or hostname.  IP addresses can
  78        be either an IPv4 address or an IPV6 address if supported.  If IPv6
  79        is not supported, then --listen=hostname is also not supported and
  80        --listen must be given an IPv4 address.
  81        Incompatible with '--inetd' option.
  82
  83--port=n::
  84        Listen on an alternative port.  Incompatible with '--inetd' option.
  85
  86--init-timeout::
  87        Timeout between the moment the connection is established and the
  88        client request is received (typically a rather low value, since
  89        that should be basically immediate).
  90
  91--timeout::
  92        Timeout for specific client sub-requests. This includes the time
  93        it takes for the server to process the sub-request and time spent
  94        waiting for next client's request.
  95
  96--syslog::
  97        Log to syslog instead of stderr. Note that this option does not imply
  98        --verbose, thus by default only error conditions will be logged.
  99
 100--user-path, --user-path=path::
 101        Allow ~user notation to be used in requests.  When
 102        specified with no parameter, requests to
 103        git://host/~alice/foo is taken as a request to access
 104        'foo' repository in the home directory of user `alice`.
 105        If `--user-path=path` is specified, the same request is
 106        taken as a request to access `path/foo` repository in
 107        the home directory of user `alice`.
 108
 109--verbose::
 110        Log details about the incoming connections and requested files.
 111
 112--reuseaddr::
 113        Use SO_REUSEADDR when binding the listening socket.
 114        This allows the server to restart without waiting for
 115        old connections to time out.
 116
 117--detach::
 118        Detach from the shell. Implies --syslog.
 119
 120--pid-file=file::
 121        Save the process id in 'file'.
 122
 123--user=user, --group=group::
 124        Change daemon's uid and gid before entering the service loop.
 125        When only `--user` is given without `--group`, the
 126        primary group ID for the user is used.  The values of
 127        the option are given to `getpwnam(3)` and `getgrnam(3)`
 128        and numeric IDs are not supported.
 129+
 130Giving these options is an error when used with `--inetd`; use
 131the facility of inet daemon to achieve the same before spawning
 132`git-daemon` if needed.
 133
 134--enable=service, --disable=service::
 135        Enable/disable the service site-wide per default.  Note
 136        that a service disabled site-wide can still be enabled
 137        per repository if it is marked overridable and the
 138        repository enables the service with an configuration
 139        item.
 140
 141--allow-override=service, --forbid-override=service::
 142        Allow/forbid overriding the site-wide default with per
 143        repository configuration.  By default, all the services
 144        are overridable.
 145
 146<directory>::
 147        A directory to add to the whitelist of allowed directories. Unless
 148        --strict-paths is specified this will also include subdirectories
 149        of each named directory.
 150
 151SERVICES
 152--------
 153
 154upload-pack::
 155        This serves `git-fetch-pack` and `git-peek-remote`
 156        clients.  It is enabled by default, but a repository can
 157        disable it by setting `daemon.uploadpack` configuration
 158        item to `false`.
 159
 160upload-archive::
 161        This serves `git-archive --remote`.
 162
 163EXAMPLES
 164--------
 165We assume the following in /etc/services::
 166+
 167------------
 168$ grep 9418 /etc/services
 169git             9418/tcp                # Git Version Control System
 170------------
 171
 172git-daemon as inetd server::
 173        To set up `git-daemon` as an inetd service that handles any
 174        repository under the whitelisted set of directories, /pub/foo
 175        and /pub/bar, place an entry like the following into
 176        /etc/inetd all on one line:
 177+
 178------------------------------------------------
 179        git stream tcp nowait nobody  /usr/bin/git-daemon
 180                git-daemon --inetd --verbose --export-all
 181                /pub/foo /pub/bar
 182------------------------------------------------
 183
 184
 185git-daemon as inetd server for virtual hosts::
 186        To set up `git-daemon` as an inetd service that handles
 187        repositories for different virtual hosts, `www.example.com`
 188        and `www.example.org`, place an entry like the following into
 189        `/etc/inetd` all on one line:
 190+
 191------------------------------------------------
 192        git stream tcp nowait nobody /usr/bin/git-daemon
 193                git-daemon --inetd --verbose --export-all
 194                --interpolated-path=/pub/%H%D
 195                /pub/www.example.org/software
 196                /pub/www.example.com/software
 197                /software
 198------------------------------------------------
 199+
 200In this example, the root-level directory `/pub` will contain
 201a subdirectory for each virtual host name supported.
 202Further, both hosts advertise repositories simply as
 203`git://www.example.com/software/repo.git`.  For pre-1.4.0
 204clients, a symlink from `/software` into the appropriate
 205default repository could be made as well.
 206
 207
 208git-daemon as regular daemon for virtual hosts::
 209        To set up `git-daemon` as a regular, non-inetd service that
 210        handles repositories for multiple virtual hosts based on
 211        their IP addresses, start the daemon like this:
 212+
 213------------------------------------------------
 214        git-daemon --verbose --export-all
 215                --interpolated-path=/pub/%IP/%D
 216                /pub/192.168.1.200/software
 217                /pub/10.10.220.23/software
 218------------------------------------------------
 219+
 220In this example, the root-level directory `/pub` will contain
 221a subdirectory for each virtual host IP address supported.
 222Repositories can still be accessed by hostname though, assuming
 223they correspond to these IP addresses.
