  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-peek-remote` clients that are invoked
  35 from `git-fetch`, `git-ls-remote`, 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 --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 +
 130 Giving these options is an error when used with `--inetd`; use
 131 the 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
 151 SERVICES
 152 --------
 153
 154 upload-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
 160 upload-archive::
 161         This serves `git-archive --remote`.
 162
 163 EXAMPLES
 164 --------
 165 We assume the following in /etc/services::
 166 +
 167 ------------
 168 $ grep 9418 /etc/services
 169 git             9418/tcp                # Git Version Control System
 170 ------------
 171
 172 git-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
 185 git-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 +
 200 In this example, the root-level directory `/pub` will contain
 201 a subdirectory for each virtual host name supported.
 202 Further, both hosts advertise repositories simply as
 203 `git://www.example.com/software/repo.git`.  For pre-1.4.0
 204 clients, a symlink from `/software` into the appropriate
 205 default repository could be made as well.
 206
 207
 208 git-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 +
 220 In this example, the root-level directory `/pub` will contain
 221 a subdirectory for each virtual host IP address supported.
 222 Repositories can still be accessed by hostname though, assuming
 223 they correspond to these IP addresses.
