28 A really simple TCP Git daemon that normally listens on port "DEFAULT_GIT_PORT"
29 aka 9418. It waits for a connection asking for a service, and will serve
30 that service if it is enabled.
32 It verifies that the directory has the magic file "git-daemon-export-ok", and
33 it will refuse to export any Git directory that hasn't explicitly been marked
34 for export this way (unless the `--export-all` parameter is specified). If you
35 pass some directory paths as 'git daemon' arguments, you can further restrict
36 the offers to a whitelist comprising of those.
38 By default, only `upload-pack` service is enabled, which serves
39 'git fetch-pack' and 'git ls-remote' clients, which are invoked
40 from 'git fetch', 'git pull', and 'git clone'.
42 This is ideally suited for read-only updates, i.e., pulling from
45 An `upload-archive` also exists to serve 'git archive'.
50 Match paths exactly (i.e. don't allow "/foo/repo" when the real path is
51 "/foo/repo.git" or "/foo/repo/.git") and don't do user-relative paths.
52 'git daemon' will refuse to start when this option is enabled and no
53 whitelist is specified.
56 Remap all the path requests as relative to the given path.
57 This is sort of "Git root" - if you run 'git daemon' with
58 '--base-path=/srv/git' on example.com, then if you later try to pull
59 'git://example.com/hello.git', 'git daemon' will interpret the path
60 as '/srv/git/hello.git'.
63 If --base-path is enabled and repo lookup fails, with this option
64 'git daemon' will attempt to lookup without prefixing the base path.
65 This is useful for switching to --base-path usage, while still
66 allowing the old paths.
68 --interpolated-path=<pathtemplate>::
69 To support virtual hosting, an interpolated path template can be
70 used to dynamically construct alternate paths. The template
71 supports %H for the target hostname as supplied by the client but
72 converted to all lowercase, %CH for the canonical hostname,
73 %IP for the server's IP address, %P for the port number,
74 and %D for the absolute path of the named repository.
75 After interpolation, the path is validated against the directory
79 Allow pulling from all directories that look like Git repositories
80 (have the 'objects' and 'refs' subdirectories), even if they
81 do not have the 'git-daemon-export-ok' file.
84 Have the server run as an inetd service. Implies --syslog (may be
85 overridden with `--log-destination=`).
86 Incompatible with --detach, --port, --listen, --user and --group
89 --listen=<host_or_ipaddr>::
90 Listen on a specific IP address or hostname. IP addresses can
91 be either an IPv4 address or an IPv6 address if supported. If IPv6
92 is not supported, then --listen=hostname is also not supported and
93 --listen must be given an IPv4 address.
94 Can be given more than once.
95 Incompatible with `--inetd` option.
98 Listen on an alternative port. Incompatible with `--inetd` option.
101 Timeout (in seconds) between the moment the connection is established
102 and the client request is received (typically a rather low value, since
103 that should be basically immediate).
106 Timeout (in seconds) for specific client sub-requests. This includes
107 the time it takes for the server to process the sub-request and the
108 time spent waiting for the next client's request.
110 --max-connections=<n>::
111 Maximum number of concurrent clients, defaults to 32. Set it to
115 Short for `--log-destination=syslog`.
117 --log-destination=<destination>::
118 Send log messages to the specified destination.
119 Note that this option does not imply --verbose,
120 thus by default only error conditions will be logged.
121 The <destination> must be one of:
125 Write to standard error.
126 Note that if `--detach` is specified,
127 the process disconnects from the real standard error,
128 making this destination effectively equivalent to `none`.
130 Write to syslog, using the `git-daemon` identifier.
135 The default destination is `syslog` if `--inetd` or `--detach` is specified,
140 Allow {tilde}user notation to be used in requests. When
141 specified with no parameter, requests to
142 git://host/{tilde}alice/foo is taken as a request to access
143 'foo' repository in the home directory of user `alice`.
144 If `--user-path=path` is specified, the same request is
145 taken as a request to access `path/foo` repository in
146 the home directory of user `alice`.
149 Log details about the incoming connections and requested files.
152 Use SO_REUSEADDR when binding the listening socket.
153 This allows the server to restart without waiting for
154 old connections to time out.
157 Detach from the shell. Implies --syslog.
160 Save the process id in 'file'. Ignored when the daemon
161 is run under `--inetd`.
165 Change daemon's uid and gid before entering the service loop.
166 When only `--user` is given without `--group`, the
167 primary group ID for the user is used. The values of
168 the option are given to `getpwnam(3)` and `getgrnam(3)`
169 and numeric IDs are not supported.
171 Giving these options is an error when used with `--inetd`; use
172 the facility of inet daemon to achieve the same before spawning
173 'git daemon' if needed.
175 Like many programs that switch user id, the daemon does not reset
176 environment variables such as `$HOME` when it runs git programs,
177 e.g. `upload-pack` and `receive-pack`. When using this option, you
178 may also want to set and export `HOME` to point at the home
179 directory of `<user>` before starting the daemon, and make sure any
180 Git configuration files in that directory are readable by `<user>`.
183 --disable=<service>::
184 Enable/disable the service site-wide per default. Note
185 that a service disabled site-wide can still be enabled
186 per repository if it is marked overridable and the
187 repository enables the service with a configuration
190 --allow-override=<service>::
191 --forbid-override=<service>::
192 Allow/forbid overriding the site-wide default with per
193 repository configuration. By default, all the services
196 --[no-]informative-errors::
197 When informative errors are turned on, git-daemon will report
198 more verbose errors to the client, differentiating conditions
199 like "no such repository" from "repository not exported". This
200 is more convenient for clients, but may leak information about
201 the existence of unexported repositories. When informative
202 errors are not enabled, all errors report "access denied" to the
203 client. The default is --no-informative-errors.
205 --access-hook=<path>::
206 Every time a client connects, first run an external command
207 specified by the <path> with service name (e.g. "upload-pack"),
208 path to the repository, hostname (%H), canonical hostname
209 (%CH), IP address (%IP), and TCP port (%P) as its command-line
210 arguments. The external command can decide to decline the
211 service by exiting with a non-zero status (or to allow it by
212 exiting with a zero status). It can also look at the $REMOTE_ADDR
213 and `$REMOTE_PORT` environment variables to learn about the
214 requestor when making this decision.
216 The external command can optionally write a single line to its
217 standard output to be sent to the requestor as an error message when
218 it declines the service.
221 A directory to add to the whitelist of allowed directories. Unless
222 --strict-paths is specified this will also include subdirectories
223 of each named directory.
228 These services can be globally enabled/disabled using the
229 command-line options of this command. If finer-grained
230 control is desired (e.g. to allow 'git archive' to be run
231 against only in a few selected repositories the daemon serves),
232 the per-repository configuration file can be used to enable or
236 This serves 'git fetch-pack' and 'git ls-remote'
237 clients. It is enabled by default, but a repository can
238 disable it by setting `daemon.uploadpack` configuration
242 This serves 'git archive --remote'. It is disabled by
243 default, but a repository can enable it by setting
244 `daemon.uploadarch` configuration item to `true`.
247 This serves 'git send-pack' clients, allowing anonymous
248 push. It is disabled by default, as there is _no_
249 authentication in the protocol (in other words, anybody
250 can push anything into the repository, including removal
251 of refs). This is solely meant for a closed LAN setting
252 where everybody is friendly. This service can be
253 enabled by setting `daemon.receivepack` configuration item to
258 We assume the following in /etc/services::
261 $ grep 9418 /etc/services
262 git 9418/tcp # Git Version Control System
265 'git daemon' as inetd server::
266 To set up 'git daemon' as an inetd service that handles any
267 repository under the whitelisted set of directories, /pub/foo
268 and /pub/bar, place an entry like the following into
269 /etc/inetd all on one line:
271 ------------------------------------------------
272 git stream tcp nowait nobody /usr/bin/git
273 git daemon --inetd --verbose --export-all
275 ------------------------------------------------
278 'git daemon' as inetd server for virtual hosts::
279 To set up 'git daemon' as an inetd service that handles
280 repositories for different virtual hosts, `www.example.com`
281 and `www.example.org`, place an entry like the following into
282 `/etc/inetd` all on one line:
284 ------------------------------------------------
285 git stream tcp nowait nobody /usr/bin/git
286 git daemon --inetd --verbose --export-all
287 --interpolated-path=/pub/%H%D
288 /pub/www.example.org/software
289 /pub/www.example.com/software
291 ------------------------------------------------
293 In this example, the root-level directory `/pub` will contain
294 a subdirectory for each virtual host name supported.
295 Further, both hosts advertise repositories simply as
296 `git://www.example.com/software/repo.git`. For pre-1.4.0
297 clients, a symlink from `/software` into the appropriate
298 default repository could be made as well.
301 'git daemon' as regular daemon for virtual hosts::
302 To set up 'git daemon' as a regular, non-inetd service that
303 handles repositories for multiple virtual hosts based on
304 their IP addresses, start the daemon like this:
306 ------------------------------------------------
307 git daemon --verbose --export-all
308 --interpolated-path=/pub/%IP/%D
309 /pub/192.168.1.200/software
310 /pub/10.10.220.23/software
311 ------------------------------------------------
313 In this example, the root-level directory `/pub` will contain
314 a subdirectory for each virtual host IP address supported.
315 Repositories can still be accessed by hostname though, assuming
316 they correspond to these IP addresses.
318 selectively enable/disable services per repository::
319 To enable 'git archive --remote' and disable 'git fetch' against
320 a repository, have the following in the configuration file in the
321 repository (that is the file 'config' next to `HEAD`, 'refs' and
324 ----------------------------------------------------------------
328 ----------------------------------------------------------------
333 'git daemon' will set REMOTE_ADDR to the IP address of the client
334 that connected to it, if the IP address is available. REMOTE_ADDR will
335 be available in the environment of hooks called when
336 services are performed.
