  21 DESCRIPTION
  22 -----------
  23 A really simple TCP git daemon that normally listens on port "DEFAULT_GIT_PORT"
  24 aka 9418.  It waits for a connection asking for a service, and will serve
  25 that service if it is enabled.
  26
  27 It verifies that the directory has the magic file "git-daemon-export-ok", and
  28 it will refuse to export any git directory that hasn't explicitly been marked
  29 for export this way (unless the '--export-all' parameter is specified). If you
  30 pass some directory paths as 'git-daemon' arguments, you can further restrict
  31 the offers to a whitelist comprising of those.
  32
  33 By default, only `upload-pack` service is enabled, which serves
  34 `git-fetch-pack` and `git-ls-remote` clients, which are invoked
  35 from `git-fetch`, `git-pull`, and `git-clone`.
  36
  37 This is ideally suited for read-only updates, i.e., pulling from
  38 git repositories.
  39
  40 An `upload-archive` also exists to serve `git-archive`.
  41
  42 OPTIONS
  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 --base-path-relaxed::
  58         If --base-path is enabled and repo lookup fails, with this option
  59         `git-daemon` will attempt to lookup without prefixing the base path.
  60         This is useful for switching to --base-path usage, while still
  61         allowing the old paths.
  62
  63 --interpolated-path=pathtemplate::
  64         To support virtual hosting, an interpolated path template can be
  65         used to dynamically construct alternate paths.  The template
  66         supports %H for the target hostname as supplied by the client but
  67         converted to all lowercase, %CH for the canonical hostname,
  68         %IP for the server's IP address, %P for the port number,
  69         and %D for the absolute path of the named repository.
  70         After interpolation, the path is validated against the directory
  71         whitelist.
  72
  73 --export-all::
  74         Allow pulling from all directories that look like GIT repositories
  75         (have the 'objects' and 'refs' subdirectories), even if they
  76         do not have the 'git-daemon-export-ok' file.
  77
  78 --inetd::
  79         Have the server run as an inetd service. Implies --syslog.
  80         Incompatible with --port, --listen, --user and --group options.
  81
  82 --listen=host_or_ipaddr::
  83         Listen on an a specific IP address or hostname.  IP addresses can
  84         be either an IPv4 address or an IPV6 address if supported.  If IPv6
  85         is not supported, then --listen=hostname is also not supported and
  86         --listen must be given an IPv4 address.
  87         Incompatible with '--inetd' option.
  88
  89 --port=n::
  90         Listen on an alternative port.  Incompatible with '--inetd' option.
  91
  92 --init-timeout::
  93         Timeout between the moment the connection is established and the
  94         client request is received (typically a rather low value, since
  95         that should be basically immediate).
  96
  97 --timeout::
  98         Timeout for specific client sub-requests. This includes the time
  99         it takes for the server to process the sub-request and time spent
 100         waiting for next client's request.
 101
 102 --syslog::
 103         Log to syslog instead of stderr. Note that this option does not imply
 104         --verbose, thus by default only error conditions will be logged.
 105
 106 --user-path::
 107 --user-path=path::
 108         Allow ~user notation to be used in requests.  When
 109         specified with no parameter, requests to
 110         git://host/~alice/foo is taken as a request to access
 111         'foo' repository in the home directory of user `alice`.
 112         If `--user-path=path` is specified, the same request is
 113         taken as a request to access `path/foo` repository in
 114         the home directory of user `alice`.
 115
 116 --verbose::
 117         Log details about the incoming connections and requested files.
 118
 119 --reuseaddr::
 120         Use SO_REUSEADDR when binding the listening socket.
 121         This allows the server to restart without waiting for
 122         old connections to time out.
 123
 124 --detach::
 125         Detach from the shell. Implies --syslog.
 126
 127 --pid-file=file::
 128         Save the process id in 'file'.  Ignored when the daemon
 129         is run under `--inetd`.
 130
 131 --user=user::
 132 --group=group::
 133         Change daemon's uid and gid before entering the service loop.
 134         When only `--user` is given without `--group`, the
 135         primary group ID for the user is used.  The values of
 136         the option are given to `getpwnam(3)` and `getgrnam(3)`
 137         and numeric IDs are not supported.
 138 +
 139 Giving these options is an error when used with `--inetd`; use
 140 the facility of inet daemon to achieve the same before spawning
 141 `git-daemon` if needed.
 142
 143 --enable=service::
 144 --disable=service::
 145         Enable/disable the service site-wide per default.  Note
 146         that a service disabled site-wide can still be enabled
 147         per repository if it is marked overridable and the
 148         repository enables the service with an configuration
 149         item.
 150
 151 --allow-override=service::
 152 --forbid-override=service::
 153         Allow/forbid overriding the site-wide default with per
 154         repository configuration.  By default, all the services
 155         are overridable.
 156
 157 <directory>::
 158         A directory to add to the whitelist of allowed directories. Unless
 159         --strict-paths is specified this will also include subdirectories
 160         of each named directory.
 161
 162 SERVICES
 163 --------
 164
 165 These services can be globally enabled/disabled using the
 166 command line options of this command.  If a finer-grained
 167 control is desired (e.g. to allow `git-archive` to be run
 168 against only in a few selected repositories the daemon serves),
 169 the per-repository configuration file can be used to enable or
 170 disable them.
 171
 172 upload-pack::
 173         This serves `git-fetch-pack` and `git-ls-remote`
 174         clients.  It is enabled by default, but a repository can
 175         disable it by setting `daemon.uploadpack` configuration
 176         item to `false`.
 177
 178 upload-archive::
 179         This serves `git-archive --remote`.  It is disabled by
 180         default, but a repository can enable it by setting
 181         `daemon.uploadarch` configuration item to `true`.
 182
 183 receive-pack::
 184         This serves `git-send-pack` clients, allowing anonymous
 185         push.  It is disabled by default, as there is _no_
 186         authentication in the protocol (in other words, anybody
 187         can push anything into the repository, including removal
 188         of refs).  This is solely meant for a closed LAN setting
 189         where everybody is friendly.  This service can be
 190         enabled by `daemon.receivepack` configuration item to
 191         `true`.
 192
 193 EXAMPLES
 194 --------
 195 We assume the following in /etc/services::
 196 +
 197 ------------
 198 $ grep 9418 /etc/services
 199 git             9418/tcp                # Git Version Control System
 200 ------------
 201
 202 git-daemon as inetd server::
 203         To set up `git-daemon` as an inetd service that handles any
 204         repository under the whitelisted set of directories, /pub/foo
 205         and /pub/bar, place an entry like the following into
 206         /etc/inetd all on one line:
 207 +
 208 ------------------------------------------------
 209         git stream tcp nowait nobody  /usr/bin/git
 210                 git daemon --inetd --verbose --export-all
 211                 /pub/foo /pub/bar
 212 ------------------------------------------------
 213
 214
 215 git-daemon as inetd server for virtual hosts::
 216         To set up `git-daemon` as an inetd service that handles
 217         repositories for different virtual hosts, `www.example.com`
 218         and `www.example.org`, place an entry like the following into
 219         `/etc/inetd` all on one line:
 220 +
 221 ------------------------------------------------
 222         git stream tcp nowait nobody /usr/bin/git
 223                 git daemon --inetd --verbose --export-all
 224                 --interpolated-path=/pub/%H%D
 225                 /pub/www.example.org/software
 226                 /pub/www.example.com/software
 227                 /software
 228 ------------------------------------------------
 229 +
 230 In this example, the root-level directory `/pub` will contain
 231 a subdirectory for each virtual host name supported.
 232 Further, both hosts advertise repositories simply as
 233 `git://www.example.com/software/repo.git`.  For pre-1.4.0
 234 clients, a symlink from `/software` into the appropriate
 235 default repository could be made as well.
 236
 237
 238 git-daemon as regular daemon for virtual hosts::
 239         To set up `git-daemon` as a regular, non-inetd service that
 240         handles repositories for multiple virtual hosts based on
 241         their IP addresses, start the daemon like this:
 242 +
 243 ------------------------------------------------
 244         git daemon --verbose --export-all
 245                 --interpolated-path=/pub/%IP/%D
 246                 /pub/192.168.1.200/software
 247                 /pub/10.10.220.23/software
 248 ------------------------------------------------
 249 +
 250 In this example, the root-level directory `/pub` will contain
 251 a subdirectory for each virtual host IP address supported.
 252 Repositories can still be accessed by hostname though, assuming
 253 they correspond to these IP addresses.
 254
 255 selectively enable/disable services per repository::
 256         To enable `git-archive --remote` and disable `git-fetch` against
 257         a repository, have the following in the configuration file in the
 258         repository (that is the file 'config' next to 'HEAD', 'refs' and
 259         'objects').
 260 +
 261 ----------------------------------------------------------------
 262         [daemon]
 263                 uploadpack = false
 264                 uploadarch = true
 265 ----------------------------------------------------------------
