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 Can be given more than once.
89 Incompatible with '--inetd' option.
92 Listen on an alternative port. Incompatible with '--inetd' option.
95 Timeout between the moment the connection is established and the
96 client request is received (typically a rather low value, since
97 that should be basically immediate).
100 Timeout for specific client sub-requests. This includes the time
101 it takes for the server to process the sub-request and the time spent
102 waiting for the next client's request.
104 --max-connections=<n>::
105 Maximum number of concurrent clients, defaults to 32. Set it to
109 Log to syslog instead of stderr. Note that this option does not imply
110 --verbose, thus by default only error conditions will be logged.
114 Allow {tilde}user notation to be used in requests. When
115 specified with no parameter, requests to
116 git://host/{tilde}alice/foo is taken as a request to access
117 'foo' repository in the home directory of user `alice`.
118 If `--user-path=path` is specified, the same request is
119 taken as a request to access `path/foo` repository in
120 the home directory of user `alice`.
123 Log details about the incoming connections and requested files.
126 Use SO_REUSEADDR when binding the listening socket.
127 This allows the server to restart without waiting for
128 old connections to time out.
131 Detach from the shell. Implies --syslog.
134 Save the process id in 'file'. Ignored when the daemon
135 is run under `--inetd`.
139 Change daemon's uid and gid before entering the service loop.
140 When only `--user` is given without `--group`, the
141 primary group ID for the user is used. The values of
142 the option are given to `getpwnam(3)` and `getgrnam(3)`
143 and numeric IDs are not supported.
145 Giving these options is an error when used with `--inetd`; use
146 the facility of inet daemon to achieve the same before spawning
147 'git daemon' if needed.
150 --disable=<service>::
151 Enable/disable the service site-wide per default. Note
152 that a service disabled site-wide can still be enabled
153 per repository if it is marked overridable and the
154 repository enables the service with a configuration
157 --allow-override=<service>::
158 --forbid-override=<service>::
159 Allow/forbid overriding the site-wide default with per
160 repository configuration. By default, all the services
164 A directory to add to the whitelist of allowed directories. Unless
165 --strict-paths is specified this will also include subdirectories
166 of each named directory.
171 These services can be globally enabled/disabled using the
172 command line options of this command. If a finer-grained
173 control is desired (e.g. to allow 'git archive' to be run
174 against only in a few selected repositories the daemon serves),
175 the per-repository configuration file can be used to enable or
179 This serves 'git fetch-pack' and 'git ls-remote'
180 clients. It is enabled by default, but a repository can
181 disable it by setting `daemon.uploadpack` configuration
185 This serves 'git archive --remote'. It is disabled by
186 default, but a repository can enable it by setting
187 `daemon.uploadarch` configuration item to `true`.
190 This serves 'git send-pack' clients, allowing anonymous
191 push. It is disabled by default, as there is _no_
192 authentication in the protocol (in other words, anybody
193 can push anything into the repository, including removal
194 of refs). This is solely meant for a closed LAN setting
195 where everybody is friendly. This service can be
196 enabled by `daemon.receivepack` configuration item to
201 We assume the following in /etc/services::
204 $ grep 9418 /etc/services
205 git 9418/tcp # Git Version Control System
208 'git daemon' as inetd server::
209 To set up 'git daemon' as an inetd service that handles any
210 repository under the whitelisted set of directories, /pub/foo
211 and /pub/bar, place an entry like the following into
212 /etc/inetd all on one line:
214 ------------------------------------------------
215 git stream tcp nowait nobody /usr/bin/git
216 git daemon --inetd --verbose --export-all
218 ------------------------------------------------
221 'git daemon' as inetd server for virtual hosts::
222 To set up 'git daemon' as an inetd service that handles
223 repositories for different virtual hosts, `www.example.com`
224 and `www.example.org`, place an entry like the following into
225 `/etc/inetd` all on one line:
227 ------------------------------------------------
228 git stream tcp nowait nobody /usr/bin/git
229 git daemon --inetd --verbose --export-all
230 --interpolated-path=/pub/%H%D
231 /pub/www.example.org/software
232 /pub/www.example.com/software
234 ------------------------------------------------
236 In this example, the root-level directory `/pub` will contain
237 a subdirectory for each virtual host name supported.
238 Further, both hosts advertise repositories simply as
239 `git://www.example.com/software/repo.git`. For pre-1.4.0
240 clients, a symlink from `/software` into the appropriate
241 default repository could be made as well.
244 'git daemon' as regular daemon for virtual hosts::
245 To set up 'git daemon' as a regular, non-inetd service that
246 handles repositories for multiple virtual hosts based on
247 their IP addresses, start the daemon like this:
249 ------------------------------------------------
250 git daemon --verbose --export-all
251 --interpolated-path=/pub/%IP/%D
252 /pub/192.168.1.200/software
253 /pub/10.10.220.23/software
254 ------------------------------------------------
256 In this example, the root-level directory `/pub` will contain
257 a subdirectory for each virtual host IP address supported.
258 Repositories can still be accessed by hostname though, assuming
259 they correspond to these IP addresses.
261 selectively enable/disable services per repository::
262 To enable 'git archive --remote' and disable 'git fetch' against
263 a repository, have the following in the configuration file in the
264 repository (that is the file 'config' next to 'HEAD', 'refs' and
267 ----------------------------------------------------------------
271 ----------------------------------------------------------------
276 'git daemon' will set REMOTE_ADDR to the IP address of the client
277 that connected to it, if the IP address is available. REMOTE_ADDR will
278 be available in the environment of hooks called when
279 services are performed.
