25 A really simple TCP git daemon that normally listens on port "DEFAULT_GIT_PORT"
26 aka 9418. It waits for a connection asking for a service, and will serve
27 that service if it is enabled.
29 It verifies that the directory has the magic file "git-daemon-export-ok", and
30 it will refuse to export any git directory that hasn't explicitly been marked
31 for export this way (unless the '--export-all' parameter is specified). If you
32 pass some directory paths as 'git daemon' arguments, you can further restrict
33 the offers to a whitelist comprising of those.
35 By default, only `upload-pack` service is enabled, which serves
36 'git fetch-pack' and 'git ls-remote' clients, which are invoked
37 from 'git fetch', 'git pull', and 'git clone'.
39 This is ideally suited for read-only updates, i.e., pulling from
42 An `upload-archive` also exists to serve 'git archive'.
47 Match paths exactly (i.e. don't allow "/foo/repo" when the real path is
48 "/foo/repo.git" or "/foo/repo/.git") and don't do user-relative paths.
49 'git daemon' will refuse to start when this option is enabled and no
50 whitelist is specified.
53 Remap all the path requests as relative to the given path.
54 This is sort of "GIT root" - if you run 'git daemon' with
55 '--base-path=/srv/git' on example.com, then if you later try to pull
56 'git://example.com/hello.git', 'git daemon' will interpret the path
57 as '/srv/git/hello.git'.
60 If --base-path is enabled and repo lookup fails, with this option
61 'git daemon' will attempt to lookup without prefixing the base path.
62 This is useful for switching to --base-path usage, while still
63 allowing the old paths.
65 --interpolated-path=<pathtemplate>::
66 To support virtual hosting, an interpolated path template can be
67 used to dynamically construct alternate paths. The template
68 supports %H for the target hostname as supplied by the client but
69 converted to all lowercase, %CH for the canonical hostname,
70 %IP for the server's IP address, %P for the port number,
71 and %D for the absolute path of the named repository.
72 After interpolation, the path is validated against the directory
76 Allow pulling from all directories that look like GIT repositories
77 (have the 'objects' and 'refs' subdirectories), even if they
78 do not have the 'git-daemon-export-ok' file.
81 Have the server run as an inetd service. Implies --syslog.
82 Incompatible with --detach, --port, --listen, --user and --group
85 --listen=<host_or_ipaddr>::
86 Listen on a specific IP address or hostname. IP addresses can
87 be either an IPv4 address or an IPv6 address if supported. If IPv6
88 is not supported, then --listen=hostname is also not supported and
89 --listen must be given an IPv4 address.
90 Can be given more than once.
91 Incompatible with '--inetd' option.
94 Listen on an alternative port. Incompatible with '--inetd' option.
97 Timeout (in seconds) between the moment the connection is established
98 and the client request is received (typically a rather low value, since
99 that should be basically immediate).
102 Timeout (in seconds) for specific client sub-requests. This includes
103 the time it takes for the server to process the sub-request and the
104 time spent waiting for the next client's request.
106 --max-connections=<n>::
107 Maximum number of concurrent clients, defaults to 32. Set it to
111 Log to syslog instead of stderr. Note that this option does not imply
112 --verbose, thus by default only error conditions will be logged.
116 Allow {tilde}user notation to be used in requests. When
117 specified with no parameter, requests to
118 git://host/{tilde}alice/foo is taken as a request to access
119 'foo' repository in the home directory of user `alice`.
120 If `--user-path=path` is specified, the same request is
121 taken as a request to access `path/foo` repository in
122 the home directory of user `alice`.
125 Log details about the incoming connections and requested files.
128 Use SO_REUSEADDR when binding the listening socket.
129 This allows the server to restart without waiting for
130 old connections to time out.
133 Detach from the shell. Implies --syslog.
136 Save the process id in 'file'. Ignored when the daemon
137 is run under `--inetd`.
141 Change daemon's uid and gid before entering the service loop.
142 When only `--user` is given without `--group`, the
143 primary group ID for the user is used. The values of
144 the option are given to `getpwnam(3)` and `getgrnam(3)`
145 and numeric IDs are not supported.
147 Giving these options is an error when used with `--inetd`; use
148 the facility of inet daemon to achieve the same before spawning
149 'git daemon' if needed.
152 --disable=<service>::
153 Enable/disable the service site-wide per default. Note
154 that a service disabled site-wide can still be enabled
155 per repository if it is marked overridable and the
156 repository enables the service with a configuration
159 --allow-override=<service>::
160 --forbid-override=<service>::
161 Allow/forbid overriding the site-wide default with per
162 repository configuration. By default, all the services
165 --informative-errors::
166 --no-informative-errors::
167 When informative errors are turned on, git-daemon will report
168 more verbose errors to the client, differentiating conditions
169 like "no such repository" from "repository not exported". This
170 is more convenient for clients, but may leak information about
171 the existence of unexported repositories. When informative
172 errors are not enabled, all errors report "access denied" to the
173 client. The default is --no-informative-errors.
175 --access-hook=<path>::
176 Every time a client connects, first run an external command
177 specified by the <path> with service name (e.g. "upload-pack"),
178 path to the repository, hostname (%H), canonical hostname
179 (%CH), ip address (%IP), and tcp port (%P) as its command line
180 arguments. The external command can decide to decline the
181 service by exiting with a non-zero status (or to allow it by
182 exiting with a zero status). It can also look at the $REMOTE_ADDR
183 and $REMOTE_PORT environment variables to learn about the
184 requestor when making this decision.
186 The external command can optionally write a single line to its
187 standard output to be sent to the requestor as an error message when
188 it declines the service.
191 A directory to add to the whitelist of allowed directories. Unless
192 --strict-paths is specified this will also include subdirectories
193 of each named directory.
198 These services can be globally enabled/disabled using the
199 command line options of this command. If a finer-grained
200 control is desired (e.g. to allow 'git archive' to be run
201 against only in a few selected repositories the daemon serves),
202 the per-repository configuration file can be used to enable or
206 This serves 'git fetch-pack' and 'git ls-remote'
207 clients. It is enabled by default, but a repository can
208 disable it by setting `daemon.uploadpack` configuration
212 This serves 'git archive --remote'. It is disabled by
213 default, but a repository can enable it by setting
214 `daemon.uploadarch` configuration item to `true`.
217 This serves 'git send-pack' clients, allowing anonymous
218 push. It is disabled by default, as there is _no_
219 authentication in the protocol (in other words, anybody
220 can push anything into the repository, including removal
221 of refs). This is solely meant for a closed LAN setting
222 where everybody is friendly. This service can be
223 enabled by setting `daemon.receivepack` configuration item to
228 We assume the following in /etc/services::
231 $ grep 9418 /etc/services
232 git 9418/tcp # Git Version Control System
235 'git daemon' as inetd server::
236 To set up 'git daemon' as an inetd service that handles any
237 repository under the whitelisted set of directories, /pub/foo
238 and /pub/bar, place an entry like the following into
239 /etc/inetd all on one line:
241 ------------------------------------------------
242 git stream tcp nowait nobody /usr/bin/git
243 git daemon --inetd --verbose --export-all
245 ------------------------------------------------
248 'git daemon' as inetd server for virtual hosts::
249 To set up 'git daemon' as an inetd service that handles
250 repositories for different virtual hosts, `www.example.com`
251 and `www.example.org`, place an entry like the following into
252 `/etc/inetd` all on one line:
254 ------------------------------------------------
255 git stream tcp nowait nobody /usr/bin/git
256 git daemon --inetd --verbose --export-all
257 --interpolated-path=/pub/%H%D
258 /pub/www.example.org/software
259 /pub/www.example.com/software
261 ------------------------------------------------
263 In this example, the root-level directory `/pub` will contain
264 a subdirectory for each virtual host name supported.
265 Further, both hosts advertise repositories simply as
266 `git://www.example.com/software/repo.git`. For pre-1.4.0
267 clients, a symlink from `/software` into the appropriate
268 default repository could be made as well.
271 'git daemon' as regular daemon for virtual hosts::
272 To set up 'git daemon' as a regular, non-inetd service that
273 handles repositories for multiple virtual hosts based on
274 their IP addresses, start the daemon like this:
276 ------------------------------------------------
277 git daemon --verbose --export-all
278 --interpolated-path=/pub/%IP/%D
279 /pub/192.168.1.200/software
280 /pub/10.10.220.23/software
281 ------------------------------------------------
283 In this example, the root-level directory `/pub` will contain
284 a subdirectory for each virtual host IP address supported.
285 Repositories can still be accessed by hostname though, assuming
286 they correspond to these IP addresses.
288 selectively enable/disable services per repository::
289 To enable 'git archive --remote' and disable 'git fetch' against
290 a repository, have the following in the configuration file in the
291 repository (that is the file 'config' next to 'HEAD', 'refs' and
294 ----------------------------------------------------------------
298 ----------------------------------------------------------------
303 'git daemon' will set REMOTE_ADDR to the IP address of the client
304 that connected to it, if the IP address is available. REMOTE_ADDR will
305 be available in the environment of hooks called when
306 services are performed.
