23 A really simple TCP git daemon that normally listens on port "DEFAULT_GIT_PORT"
24 aka 9418. It waits for a connection asking for a service, and will serve
25 that service if it is enabled.
27 It verifies that the directory has the magic file "git-daemon-export-ok", and
28 it will refuse to export any git directory that hasn't explicitly been marked
29 for export this way (unless the '--export-all' parameter is specified). If you
30 pass some directory paths as 'git-daemon' arguments, you can further restrict
31 the offers to a whitelist comprising of those.
33 By default, only `upload-pack` service is enabled, which serves
34 `git-fetch-pack` and `git-ls-remote` clients, which are invoked
35 from `git-fetch`, `git-pull`, and `git-clone`.
37 This is ideally suited for read-only updates, i.e., pulling from
40 An `upload-archive` also exists to serve `git-archive`.
45 Match paths exactly (i.e. don't allow "/foo/repo" when the real path is
46 "/foo/repo.git" or "/foo/repo/.git") and don't do user-relative paths.
47 git-daemon will refuse to start when this option is enabled and no
48 whitelist is specified.
51 Remap all the path requests as relative to the given path.
52 This is sort of "GIT root" - if you run git-daemon with
53 '--base-path=/srv/git' on example.com, then if you later try to pull
54 'git://example.com/hello.git', `git-daemon` will interpret the path
55 as '/srv/git/hello.git'.
58 If --base-path is enabled and repo lookup fails, with this option
59 `git-daemon` will attempt to lookup without prefixing the base path.
60 This is useful for switching to --base-path usage, while still
61 allowing the old paths.
63 --interpolated-path=pathtemplate::
64 To support virtual hosting, an interpolated path template can be
65 used to dynamically construct alternate paths. The template
66 supports %H for the target hostname as supplied by the client but
67 converted to all lowercase, %CH for the canonical hostname,
68 %IP for the server's IP address, %P for the port number,
69 and %D for the absolute path of the named repository.
70 After interpolation, the path is validated against the directory
74 Allow pulling from all directories that look like GIT repositories
75 (have the 'objects' and 'refs' subdirectories), even if they
76 do not have the 'git-daemon-export-ok' file.
79 Have the server run as an inetd service. Implies --syslog.
80 Incompatible with --port, --listen, --user and --group options.
82 --listen=host_or_ipaddr::
83 Listen on an a specific IP address or hostname. IP addresses can
84 be either an IPv4 address or an IPV6 address if supported. If IPv6
85 is not supported, then --listen=hostname is also not supported and
86 --listen must be given an IPv4 address.
87 Incompatible with '--inetd' option.
90 Listen on an alternative port. Incompatible with '--inetd' option.
93 Timeout between the moment the connection is established and the
94 client request is received (typically a rather low value, since
95 that should be basically immediate).
98 Timeout for specific client sub-requests. This includes the time
99 it takes for the server to process the sub-request and time spent
100 waiting for next client's request.
103 Log to syslog instead of stderr. Note that this option does not imply
104 --verbose, thus by default only error conditions will be logged.
106 --user-path, --user-path=path::
107 Allow ~user notation to be used in requests. When
108 specified with no parameter, requests to
109 git://host/~alice/foo is taken as a request to access
110 'foo' repository in the home directory of user `alice`.
111 If `--user-path=path` is specified, the same request is
112 taken as a request to access `path/foo` repository in
113 the home directory of user `alice`.
116 Log details about the incoming connections and requested files.
119 Use SO_REUSEADDR when binding the listening socket.
120 This allows the server to restart without waiting for
121 old connections to time out.
124 Detach from the shell. Implies --syslog.
127 Save the process id in 'file'. Ignored when the daemon
128 is run under `--inetd`.
130 --user=user, --group=group::
131 Change daemon's uid and gid before entering the service loop.
132 When only `--user` is given without `--group`, the
133 primary group ID for the user is used. The values of
134 the option are given to `getpwnam(3)` and `getgrnam(3)`
135 and numeric IDs are not supported.
137 Giving these options is an error when used with `--inetd`; use
138 the facility of inet daemon to achieve the same before spawning
139 `git-daemon` if needed.
141 --enable=service, --disable=service::
142 Enable/disable the service site-wide per default. Note
143 that a service disabled site-wide can still be enabled
144 per repository if it is marked overridable and the
145 repository enables the service with an configuration
148 --allow-override=service, --forbid-override=service::
149 Allow/forbid overriding the site-wide default with per
150 repository configuration. By default, all the services
154 A directory to add to the whitelist of allowed directories. Unless
155 --strict-paths is specified this will also include subdirectories
156 of each named directory.
161 These services can be globally enabled/disabled using the
162 command line options of this command. If a finer-grained
163 control is desired (e.g. to allow `git-archive` to be run
164 against only in a few selected repositories the daemon serves),
165 the per-repository configuration file can be used to enable or
169 This serves `git-fetch-pack` and `git-ls-remote`
170 clients. It is enabled by default, but a repository can
171 disable it by setting `daemon.uploadpack` configuration
175 This serves `git-archive --remote`. It is disabled by
176 default, but a repository can enable it by setting
177 `daemon.uploadarchive` configuration item to `true`.
180 This serves `git-send-pack` clients, allowing anonymous
181 push. It is disabled by default, as there is _no_
182 authentication in the protocol (in other words, anybody
183 can push anything into the repository, including removal
184 of refs). This is solely meant for a closed LAN setting
185 where everybody is friendly. This service can be
186 enabled by `daemon.receivepack` configuration item to
191 We assume the following in /etc/services::
194 $ grep 9418 /etc/services
195 git 9418/tcp # Git Version Control System
198 git-daemon as inetd server::
199 To set up `git-daemon` as an inetd service that handles any
200 repository under the whitelisted set of directories, /pub/foo
201 and /pub/bar, place an entry like the following into
202 /etc/inetd all on one line:
204 ------------------------------------------------
205 git stream tcp nowait nobody /usr/bin/git-daemon
206 git-daemon --inetd --verbose --export-all
208 ------------------------------------------------
211 git-daemon as inetd server for virtual hosts::
212 To set up `git-daemon` as an inetd service that handles
213 repositories for different virtual hosts, `www.example.com`
214 and `www.example.org`, place an entry like the following into
215 `/etc/inetd` all on one line:
217 ------------------------------------------------
218 git stream tcp nowait nobody /usr/bin/git-daemon
219 git-daemon --inetd --verbose --export-all
220 --interpolated-path=/pub/%H%D
221 /pub/www.example.org/software
222 /pub/www.example.com/software
224 ------------------------------------------------
226 In this example, the root-level directory `/pub` will contain
227 a subdirectory for each virtual host name supported.
228 Further, both hosts advertise repositories simply as
229 `git://www.example.com/software/repo.git`. For pre-1.4.0
230 clients, a symlink from `/software` into the appropriate
231 default repository could be made as well.
234 git-daemon as regular daemon for virtual hosts::
235 To set up `git-daemon` as a regular, non-inetd service that
236 handles repositories for multiple virtual hosts based on
237 their IP addresses, start the daemon like this:
239 ------------------------------------------------
240 git-daemon --verbose --export-all
241 --interpolated-path=/pub/%IP/%D
242 /pub/192.168.1.200/software
243 /pub/10.10.220.23/software
244 ------------------------------------------------
246 In this example, the root-level directory `/pub` will contain
247 a subdirectory for each virtual host IP address supported.
248 Repositories can still be accessed by hostname though, assuming
249 they correspond to these IP addresses.
251 selectively enable/disable services per repository::
252 To enable `git-archive --remote` and disable `git-fetch` against
253 a repository, have the following in the configuration file in the
254 repository (that is the file 'config' next to 'HEAD', 'refs' and
