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