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 --detach, --port, --listen, --user and --group
84 --listen=<host_or_ipaddr>::
85 Listen on a specific IP address or hostname. IP addresses can
86 be either an IPv4 address or an IPv6 address if supported. If IPv6
87 is not supported, then --listen=hostname is also not supported and
88 --listen must be given an IPv4 address.
89 Can be given more than once.
90 Incompatible with '--inetd' option.
93 Listen on an alternative port. Incompatible with '--inetd' option.
96 Timeout (in seconds) between the moment the connection is established
97 and the client request is received (typically a rather low value, since
98 that should be basically immediate).
101 Timeout (in seconds) for specific client sub-requests. This includes
102 the time it takes for the server to process the sub-request and the
103 time spent waiting for the next client's request.
105 --max-connections=<n>::
106 Maximum number of concurrent clients, defaults to 32. Set it to
110 Log to syslog instead of stderr. Note that this option does not imply
111 --verbose, thus by default only error conditions will be logged.
115 Allow {tilde}user notation to be used in requests. When
116 specified with no parameter, requests to
117 git://host/{tilde}alice/foo is taken as a request to access
118 'foo' repository in the home directory of user `alice`.
119 If `--user-path=path` is specified, the same request is
120 taken as a request to access `path/foo` repository in
121 the home directory of user `alice`.
124 Log details about the incoming connections and requested files.
127 Use SO_REUSEADDR when binding the listening socket.
128 This allows the server to restart without waiting for
129 old connections to time out.
132 Detach from the shell. Implies --syslog.
135 Save the process id in 'file'. Ignored when the daemon
136 is run under `--inetd`.
140 Change daemon's uid and gid before entering the service loop.
141 When only `--user` is given without `--group`, the
142 primary group ID for the user is used. The values of
143 the option are given to `getpwnam(3)` and `getgrnam(3)`
144 and numeric IDs are not supported.
146 Giving these options is an error when used with `--inetd`; use
147 the facility of inet daemon to achieve the same before spawning
148 'git daemon' if needed.
151 --disable=<service>::
152 Enable/disable the service site-wide per default. Note
153 that a service disabled site-wide can still be enabled
154 per repository if it is marked overridable and the
155 repository enables the service with a configuration
158 --allow-override=<service>::
159 --forbid-override=<service>::
160 Allow/forbid overriding the site-wide default with per
161 repository configuration. By default, all the services
164 --informative-errors::
165 --no-informative-errors::
166 When informative errors are turned on, git-daemon will report
167 more verbose errors to the client, differentiating conditions
168 like "no such repository" from "repository not exported". This
169 is more convenient for clients, but may leak information about
170 the existence of unexported repositories. When informative
171 errors are not enabled, all errors report "access denied" to the
172 client. The default is --no-informative-errors.
175 A directory to add to the whitelist of allowed directories. Unless
176 --strict-paths is specified this will also include subdirectories
177 of each named directory.
182 These services can be globally enabled/disabled using the
183 command line options of this command. If a finer-grained
184 control is desired (e.g. to allow 'git archive' to be run
185 against only in a few selected repositories the daemon serves),
186 the per-repository configuration file can be used to enable or
190 This serves 'git fetch-pack' and 'git ls-remote'
191 clients. It is enabled by default, but a repository can
192 disable it by setting `daemon.uploadpack` configuration
196 This serves 'git archive --remote'. It is disabled by
197 default, but a repository can enable it by setting
198 `daemon.uploadarch` configuration item to `true`.
201 This serves 'git send-pack' clients, allowing anonymous
202 push. It is disabled by default, as there is _no_
203 authentication in the protocol (in other words, anybody
204 can push anything into the repository, including removal
205 of refs). This is solely meant for a closed LAN setting
206 where everybody is friendly. This service can be
207 enabled by setting `daemon.receivepack` configuration item to
212 We assume the following in /etc/services::
215 $ grep 9418 /etc/services
216 git 9418/tcp # Git Version Control System
219 'git daemon' as inetd server::
220 To set up 'git daemon' as an inetd service that handles any
221 repository under the whitelisted set of directories, /pub/foo
222 and /pub/bar, place an entry like the following into
223 /etc/inetd all on one line:
225 ------------------------------------------------
226 git stream tcp nowait nobody /usr/bin/git
227 git daemon --inetd --verbose --export-all
229 ------------------------------------------------
232 'git daemon' as inetd server for virtual hosts::
233 To set up 'git daemon' as an inetd service that handles
234 repositories for different virtual hosts, `www.example.com`
235 and `www.example.org`, place an entry like the following into
236 `/etc/inetd` all on one line:
238 ------------------------------------------------
239 git stream tcp nowait nobody /usr/bin/git
240 git daemon --inetd --verbose --export-all
241 --interpolated-path=/pub/%H%D
242 /pub/www.example.org/software
243 /pub/www.example.com/software
245 ------------------------------------------------
247 In this example, the root-level directory `/pub` will contain
248 a subdirectory for each virtual host name supported.
249 Further, both hosts advertise repositories simply as
250 `git://www.example.com/software/repo.git`. For pre-1.4.0
251 clients, a symlink from `/software` into the appropriate
252 default repository could be made as well.
255 'git daemon' as regular daemon for virtual hosts::
256 To set up 'git daemon' as a regular, non-inetd service that
257 handles repositories for multiple virtual hosts based on
258 their IP addresses, start the daemon like this:
260 ------------------------------------------------
261 git daemon --verbose --export-all
262 --interpolated-path=/pub/%IP/%D
263 /pub/192.168.1.200/software
264 /pub/10.10.220.23/software
265 ------------------------------------------------
267 In this example, the root-level directory `/pub` will contain
268 a subdirectory for each virtual host IP address supported.
269 Repositories can still be accessed by hostname though, assuming
270 they correspond to these IP addresses.
272 selectively enable/disable services per repository::
273 To enable 'git archive --remote' and disable 'git fetch' against
274 a repository, have the following in the configuration file in the
275 repository (that is the file 'config' next to 'HEAD', 'refs' and
278 ----------------------------------------------------------------
282 ----------------------------------------------------------------
287 'git daemon' will set REMOTE_ADDR to the IP address of the client
288 that connected to it, if the IP address is available. REMOTE_ADDR will
289 be available in the environment of hooks called when
290 services are performed.
