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 between the moment the connection is established and the
97 client request is received (typically a rather low value, since
98 that should be basically immediate).
101 Timeout for specific client sub-requests. This includes the time
102 it takes for the server to process the sub-request and the time spent
103 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
165 A directory to add to the whitelist of allowed directories. Unless
166 --strict-paths is specified this will also include subdirectories
167 of each named directory.
172 These services can be globally enabled/disabled using the
173 command line options of this command. If a finer-grained
174 control is desired (e.g. to allow 'git archive' to be run
175 against only in a few selected repositories the daemon serves),
176 the per-repository configuration file can be used to enable or
180 This serves 'git fetch-pack' and 'git ls-remote'
181 clients. It is enabled by default, but a repository can
182 disable it by setting `daemon.uploadpack` configuration
186 This serves 'git archive --remote'. It is disabled by
187 default, but a repository can enable it by setting
188 `daemon.uploadarch` configuration item to `true`.
191 This serves 'git send-pack' clients, allowing anonymous
192 push. It is disabled by default, as there is _no_
193 authentication in the protocol (in other words, anybody
194 can push anything into the repository, including removal
195 of refs). This is solely meant for a closed LAN setting
196 where everybody is friendly. This service can be
197 enabled by `daemon.receivepack` configuration item to
202 We assume the following in /etc/services::
205 $ grep 9418 /etc/services
206 git 9418/tcp # Git Version Control System
209 'git daemon' as inetd server::
210 To set up 'git daemon' as an inetd service that handles any
211 repository under the whitelisted set of directories, /pub/foo
212 and /pub/bar, place an entry like the following into
213 /etc/inetd all on one line:
215 ------------------------------------------------
216 git stream tcp nowait nobody /usr/bin/git
217 git daemon --inetd --verbose --export-all
219 ------------------------------------------------
222 'git daemon' as inetd server for virtual hosts::
223 To set up 'git daemon' as an inetd service that handles
224 repositories for different virtual hosts, `www.example.com`
225 and `www.example.org`, place an entry like the following into
226 `/etc/inetd` all on one line:
228 ------------------------------------------------
229 git stream tcp nowait nobody /usr/bin/git
230 git daemon --inetd --verbose --export-all
231 --interpolated-path=/pub/%H%D
232 /pub/www.example.org/software
233 /pub/www.example.com/software
235 ------------------------------------------------
237 In this example, the root-level directory `/pub` will contain
238 a subdirectory for each virtual host name supported.
239 Further, both hosts advertise repositories simply as
240 `git://www.example.com/software/repo.git`. For pre-1.4.0
241 clients, a symlink from `/software` into the appropriate
242 default repository could be made as well.
245 'git daemon' as regular daemon for virtual hosts::
246 To set up 'git daemon' as a regular, non-inetd service that
247 handles repositories for multiple virtual hosts based on
248 their IP addresses, start the daemon like this:
250 ------------------------------------------------
251 git daemon --verbose --export-all
252 --interpolated-path=/pub/%IP/%D
253 /pub/192.168.1.200/software
254 /pub/10.10.220.23/software
255 ------------------------------------------------
257 In this example, the root-level directory `/pub` will contain
258 a subdirectory for each virtual host IP address supported.
259 Repositories can still be accessed by hostname though, assuming
260 they correspond to these IP addresses.
262 selectively enable/disable services per repository::
263 To enable 'git archive --remote' and disable 'git fetch' against
264 a repository, have the following in the configuration file in the
265 repository (that is the file 'config' next to 'HEAD', 'refs' and
268 ----------------------------------------------------------------
272 ----------------------------------------------------------------
277 'git daemon' will set REMOTE_ADDR to the IP address of the client
278 that connected to it, if the IP address is available. REMOTE_ADDR will
279 be available in the environment of hooks called when
280 services are performed.
