24 A really simple TCP git daemon that normally listens on port "DEFAULT_GIT_PORT"
25 aka 9418. It waits for a connection asking for a service, and will serve
26 that service if it is enabled.
28 It verifies that the directory has the magic file "git-daemon-export-ok", and
29 it will refuse to export any git directory that hasn't explicitly been marked
30 for export this way (unless the '--export-all' parameter is specified). If you
31 pass some directory paths as 'git-daemon' arguments, you can further restrict
32 the offers to a whitelist comprising of those.
34 By default, only `upload-pack` service is enabled, which serves
35 'git-fetch-pack' and 'git-ls-remote' clients, which are invoked
36 from 'git-fetch', 'git-pull', and 'git-clone'.
38 This is ideally suited for read-only updates, i.e., pulling from
41 An `upload-archive` also exists to serve 'git-archive'.
46 Match paths exactly (i.e. don't allow "/foo/repo" when the real path is
47 "/foo/repo.git" or "/foo/repo/.git") and don't do user-relative paths.
48 'git-daemon' will refuse to start when this option is enabled and no
49 whitelist is specified.
52 Remap all the path requests as relative to the given path.
53 This is sort of "GIT root" - if you run 'git-daemon' with
54 '--base-path=/srv/git' on example.com, then if you later try to pull
55 'git://example.com/hello.git', 'git-daemon' will interpret the path
56 as '/srv/git/hello.git'.
59 If --base-path is enabled and repo lookup fails, with this option
60 'git-daemon' will attempt to lookup without prefixing the base path.
61 This is useful for switching to --base-path usage, while still
62 allowing the old paths.
64 --interpolated-path=pathtemplate::
65 To support virtual hosting, an interpolated path template can be
66 used to dynamically construct alternate paths. The template
67 supports %H for the target hostname as supplied by the client but
68 converted to all lowercase, %CH for the canonical hostname,
69 %IP for the server's IP address, %P for the port number,
70 and %D for the absolute path of the named repository.
71 After interpolation, the path is validated against the directory
75 Allow pulling from all directories that look like GIT repositories
76 (have the 'objects' and 'refs' subdirectories), even if they
77 do not have the 'git-daemon-export-ok' file.
80 Have the server run as an inetd service. Implies --syslog.
81 Incompatible with --port, --listen, --user and --group options.
83 --listen=host_or_ipaddr::
84 Listen on a specific IP address or hostname. IP addresses can
85 be either an IPv4 address or an IPv6 address if supported. If IPv6
86 is not supported, then --listen=hostname is also not supported and
87 --listen must be given an IPv4 address.
88 Incompatible with '--inetd' option.
91 Listen on an alternative port. Incompatible with '--inetd' option.
94 Timeout between the moment the connection is established and the
95 client request is received (typically a rather low value, since
96 that should be basically immediate).
99 Timeout for specific client sub-requests. This includes the time
100 it takes for the server to process the sub-request and the time spent
101 waiting for the next client's request.
103 --max-connections=n::
104 Maximum number of concurrent clients, defaults to 32. Set it to
108 Log to syslog instead of stderr. Note that this option does not imply
109 --verbose, thus by default only error conditions will be logged.
113 Allow {tilde}user notation to be used in requests. When
114 specified with no parameter, requests to
115 git://host/{tilde}alice/foo is taken as a request to access
116 'foo' repository in the home directory of user `alice`.
117 If `--user-path=path` is specified, the same request is
118 taken as a request to access `path/foo` repository in
119 the home directory of user `alice`.
122 Log details about the incoming connections and requested files.
125 Use SO_REUSEADDR when binding the listening socket.
126 This allows the server to restart without waiting for
127 old connections to time out.
130 Detach from the shell. Implies --syslog.
133 Save the process id in 'file'. Ignored when the daemon
134 is run under `--inetd`.
138 Change daemon's uid and gid before entering the service loop.
139 When only `--user` is given without `--group`, the
140 primary group ID for the user is used. The values of
141 the option are given to `getpwnam(3)` and `getgrnam(3)`
142 and numeric IDs are not supported.
144 Giving these options is an error when used with `--inetd`; use
145 the facility of inet daemon to achieve the same before spawning
146 'git-daemon' if needed.
150 Enable/disable the service site-wide per default. Note
151 that a service disabled site-wide can still be enabled
152 per repository if it is marked overridable and the
153 repository enables the service with a configuration
156 --allow-override=service::
157 --forbid-override=service::
158 Allow/forbid overriding the site-wide default with per
159 repository configuration. By default, all the services
163 A directory to add to the whitelist of allowed directories. Unless
164 --strict-paths is specified this will also include subdirectories
165 of each named directory.
170 These services can be globally enabled/disabled using the
171 command line options of this command. If a finer-grained
172 control is desired (e.g. to allow 'git-archive' to be run
173 against only in a few selected repositories the daemon serves),
174 the per-repository configuration file can be used to enable or
178 This serves 'git-fetch-pack' and 'git-ls-remote'
179 clients. It is enabled by default, but a repository can
180 disable it by setting `daemon.uploadpack` configuration
184 This serves 'git-archive --remote'. It is disabled by
185 default, but a repository can enable it by setting
186 `daemon.uploadarch` configuration item to `true`.
189 This serves 'git-send-pack' clients, allowing anonymous
190 push. It is disabled by default, as there is _no_
191 authentication in the protocol (in other words, anybody
192 can push anything into the repository, including removal
193 of refs). This is solely meant for a closed LAN setting
194 where everybody is friendly. This service can be
195 enabled by `daemon.receivepack` configuration item to
200 We assume the following in /etc/services::
203 $ grep 9418 /etc/services
204 git 9418/tcp # Git Version Control System
207 'git-daemon' as inetd server::
208 To set up 'git-daemon' as an inetd service that handles any
209 repository under the whitelisted set of directories, /pub/foo
210 and /pub/bar, place an entry like the following into
211 /etc/inetd all on one line:
213 ------------------------------------------------
214 git stream tcp nowait nobody /usr/bin/git
215 git daemon --inetd --verbose --export-all
217 ------------------------------------------------
220 'git-daemon' as inetd server for virtual hosts::
221 To set up 'git-daemon' as an inetd service that handles
222 repositories for different virtual hosts, `www.example.com`
223 and `www.example.org`, place an entry like the following into
224 `/etc/inetd` all on one line:
226 ------------------------------------------------
227 git stream tcp nowait nobody /usr/bin/git
228 git daemon --inetd --verbose --export-all
229 --interpolated-path=/pub/%H%D
230 /pub/www.example.org/software
231 /pub/www.example.com/software
233 ------------------------------------------------
235 In this example, the root-level directory `/pub` will contain
236 a subdirectory for each virtual host name supported.
237 Further, both hosts advertise repositories simply as
238 `git://www.example.com/software/repo.git`. For pre-1.4.0
239 clients, a symlink from `/software` into the appropriate
240 default repository could be made as well.
243 'git-daemon' as regular daemon for virtual hosts::
244 To set up 'git-daemon' as a regular, non-inetd service that
245 handles repositories for multiple virtual hosts based on
246 their IP addresses, start the daemon like this:
248 ------------------------------------------------
249 git daemon --verbose --export-all
250 --interpolated-path=/pub/%IP/%D
251 /pub/192.168.1.200/software
252 /pub/10.10.220.23/software
253 ------------------------------------------------
255 In this example, the root-level directory `/pub` will contain
256 a subdirectory for each virtual host IP address supported.
257 Repositories can still be accessed by hostname though, assuming
258 they correspond to these IP addresses.
260 selectively enable/disable services per repository::
261 To enable 'git-archive --remote' and disable 'git-fetch' against
262 a repository, have the following in the configuration file in the
263 repository (that is the file 'config' next to 'HEAD', 'refs' and
266 ----------------------------------------------------------------
270 ----------------------------------------------------------------
275 'git-daemon' will set REMOTE_ADDR to the IP address of the client
276 that connected to it, if the IP address is available. REMOTE_ADDR will
277 be available in the environment of hooks called when
278 services are performed.
