  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, --user-path=path::
 107         Allow ~user notation to be used in requests.  When
 108         specified with no parameter, requests to
 109         git://host/~alice/foo is taken as a request to access
 110         'foo' repository in the home directory of user `alice`.
 111         If `--user-path=path` is specified, the same request is
 112         taken as a request to access `path/foo` repository in
 113         the home directory of user `alice`.
 114
 115 --verbose::
 116         Log details about the incoming connections and requested files.
 117
 118 --reuseaddr::
 119         Use SO_REUSEADDR when binding the listening socket.
 120         This allows the server to restart without waiting for
 121         old connections to time out.
 122
 123 --detach::
 124         Detach from the shell. Implies --syslog.
 125
 126 --pid-file=file::
 127         Save the process id in 'file'.  Ignored when the daemon
 128         is run under `--inetd`.
 129
 130 --user=user, --group=group::
 131         Change daemon's uid and gid before entering the service loop.
 132         When only `--user` is given without `--group`, the
 133         primary group ID for the user is used.  The values of
 134         the option are given to `getpwnam(3)` and `getgrnam(3)`
 135         and numeric IDs are not supported.
 136 +
 137 Giving these options is an error when used with `--inetd`; use
 138 the facility of inet daemon to achieve the same before spawning
 139 `git-daemon` if needed.
 140
 141 --enable=service, --disable=service::
 142         Enable/disable the service site-wide per default.  Note
 143         that a service disabled site-wide can still be enabled
 144         per repository if it is marked overridable and the
 145         repository enables the service with an configuration
 146         item.
 147
 148 --allow-override=service, --forbid-override=service::
 149         Allow/forbid overriding the site-wide default with per
 150         repository configuration.  By default, all the services
 151         are overridable.
 152
 153 <directory>::
 154         A directory to add to the whitelist of allowed directories. Unless
 155         --strict-paths is specified this will also include subdirectories
 156         of each named directory.
 157
 158 SERVICES
 159 --------
 160
 161 These services can be globally enabled/disabled using the
 162 command line options of this command.  If a finer-grained
 163 control is desired (e.g. to allow `git-archive` to be run
 164 against only in a few selected repositories the daemon serves),
 165 the per-repository configuration file can be used to enable or
 166 disable them.
 167
 168 upload-pack::
 169         This serves `git-fetch-pack` and `git-ls-remote`
 170         clients.  It is enabled by default, but a repository can
 171         disable it by setting `daemon.uploadpack` configuration
 172         item to `false`.
 173
 174 upload-archive::
 175         This serves `git-archive --remote`.  It is disabled by
 176         default, but a repository can enable it by setting
 177         `daemon.uploadarch` configuration item to `true`.
 178
 179 receive-pack::
 180         This serves `git-send-pack` clients, allowing anonymous
 181         push.  It is disabled by default, as there is _no_
 182         authentication in the protocol (in other words, anybody
 183         can push anything into the repository, including removal
 184         of refs).  This is solely meant for a closed LAN setting
 185         where everybody is friendly.  This service can be
 186         enabled by `daemon.receivepack` configuration item to
 187         `true`.
 188
 189 EXAMPLES
 190 --------
 191 We assume the following in /etc/services::
 192 +
 193 ------------
 194 $ grep 9418 /etc/services
 195 git             9418/tcp                # Git Version Control System
 196 ------------
 197
 198 git-daemon as inetd server::
 199         To set up `git-daemon` as an inetd service that handles any
 200         repository under the whitelisted set of directories, /pub/foo
 201         and /pub/bar, place an entry like the following into
 202         /etc/inetd all on one line:
 203 +
 204 ------------------------------------------------
 205         git stream tcp nowait nobody  /usr/bin/git-daemon
 206                 git-daemon --inetd --verbose --export-all
 207                 /pub/foo /pub/bar
 208 ------------------------------------------------
 209
 210
 211 git-daemon as inetd server for virtual hosts::
 212         To set up `git-daemon` as an inetd service that handles
 213         repositories for different virtual hosts, `www.example.com`
 214         and `www.example.org`, place an entry like the following into
 215         `/etc/inetd` all on one line:
 216 +
 217 ------------------------------------------------
 218         git stream tcp nowait nobody /usr/bin/git-daemon
 219                 git-daemon --inetd --verbose --export-all
 220                 --interpolated-path=/pub/%H%D
 221                 /pub/www.example.org/software
 222                 /pub/www.example.com/software
 223                 /software
 224 ------------------------------------------------
 225 +
 226 In this example, the root-level directory `/pub` will contain
 227 a subdirectory for each virtual host name supported.
 228 Further, both hosts advertise repositories simply as
 229 `git://www.example.com/software/repo.git`.  For pre-1.4.0
 230 clients, a symlink from `/software` into the appropriate
 231 default repository could be made as well.
 232
 233
 234 git-daemon as regular daemon for virtual hosts::
 235         To set up `git-daemon` as a regular, non-inetd service that
 236         handles repositories for multiple virtual hosts based on
 237         their IP addresses, start the daemon like this:
 238 +
 239 ------------------------------------------------
 240         git-daemon --verbose --export-all
 241                 --interpolated-path=/pub/%IP/%D
 242                 /pub/192.168.1.200/software
 243                 /pub/10.10.220.23/software
 244 ------------------------------------------------
 245 +
 246 In this example, the root-level directory `/pub` will contain
 247 a subdirectory for each virtual host IP address supported.
 248 Repositories can still be accessed by hostname though, assuming
 249 they correspond to these IP addresses.
 250
 251 selectively enable/disable services per repository::
 252         To enable `git-archive --remote` and disable `git-fetch` against
 253         a repository, have the following in the configuration file in the
 254         repository (that is the file 'config' next to 'HEAD', 'refs' and
 255         'objects').
 256 +
 257 ----------------------------------------------------------------
 258         [daemon]
 259                 uploadpack = false
 260                 uploadarch = true
 261 ----------------------------------------------------------------
