22 DESCRIPTION
23 -----------
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
39 git repositories.
41 An `upload-archive` also exists to serve 'git-archive'.
43 OPTIONS
44 -------
45 --strict-paths::
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.
51 --base-path::
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'.
58 --base-path-relaxed::
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
72 whitelist.
74 --export-all::
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.
79 --inetd::
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 an 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 Incompatible with '--inetd' option.
90 --port=n::
91 Listen on an alternative port. Incompatible with '--inetd' option.
93 --init-timeout::
94 Timeout between the moment the connection is established and the
95 client request is received (typically a rather low value, since
96 that should be basically immediate).
98 --timeout::
99 Timeout for specific client sub-requests. This includes the time
100 it takes for the server to process the sub-request and time spent
101 waiting for next client's request.
103 --max-connections::
104 Maximum number of concurrent clients, defaults to 32. Set it to
105 zero for no limit.
107 --syslog::
108 Log to syslog instead of stderr. Note that this option does not imply
109 --verbose, thus by default only error conditions will be logged.
111 --user-path::
112 --user-path=path::
113 Allow {tilde}user notation to be used in requests. When
114 specified with no parameter, requests to
115 git://host/{tilde}alice/foo is taken as a request to access
116 'foo' repository in the home directory of user `alice`.
117 If `--user-path=path` is specified, the same request is
118 taken as a request to access `path/foo` repository in
119 the home directory of user `alice`.
121 --verbose::
122 Log details about the incoming connections and requested files.
124 --reuseaddr::
125 Use SO_REUSEADDR when binding the listening socket.
126 This allows the server to restart without waiting for
127 old connections to time out.
129 --detach::
130 Detach from the shell. Implies --syslog.
132 --pid-file=file::
133 Save the process id in 'file'. Ignored when the daemon
134 is run under `--inetd`.
136 --user=user::
137 --group=group::
138 Change daemon's uid and gid before entering the service loop.
139 When only `--user` is given without `--group`, the
140 primary group ID for the user is used. The values of
141 the option are given to `getpwnam(3)` and `getgrnam(3)`
142 and numeric IDs are not supported.
143 +
144 Giving these options is an error when used with `--inetd`; use
145 the facility of inet daemon to achieve the same before spawning
146 'git-daemon' if needed.
148 --enable=service::
149 --disable=service::
150 Enable/disable the service site-wide per default. Note
151 that a service disabled site-wide can still be enabled
152 per repository if it is marked overridable and the
153 repository enables the service with an configuration
154 item.
156 --allow-override=service::
157 --forbid-override=service::
158 Allow/forbid overriding the site-wide default with per
159 repository configuration. By default, all the services
160 are overridable.
162 <directory>::
163 A directory to add to the whitelist of allowed directories. Unless
164 --strict-paths is specified this will also include subdirectories
165 of each named directory.
167 SERVICES
168 --------
170 These services can be globally enabled/disabled using the
171 command line options of this command. If a finer-grained
172 control is desired (e.g. to allow 'git-archive' to be run
173 against only in a few selected repositories the daemon serves),
174 the per-repository configuration file can be used to enable or
175 disable them.
177 upload-pack::
178 This serves 'git-fetch-pack' and 'git-ls-remote'
179 clients. It is enabled by default, but a repository can
180 disable it by setting `daemon.uploadpack` configuration
181 item to `false`.
183 upload-archive::
184 This serves 'git-archive --remote'. It is disabled by
185 default, but a repository can enable it by setting
186 `daemon.uploadarch` configuration item to `true`.
188 receive-pack::
189 This serves 'git-send-pack' clients, allowing anonymous
190 push. It is disabled by default, as there is _no_
191 authentication in the protocol (in other words, anybody
192 can push anything into the repository, including removal
193 of refs). This is solely meant for a closed LAN setting
194 where everybody is friendly. This service can be
195 enabled by `daemon.receivepack` configuration item to
196 `true`.
198 EXAMPLES
199 --------
200 We assume the following in /etc/services::
201 +
202 ------------
203 $ grep 9418 /etc/services
204 git 9418/tcp # Git Version Control System
205 ------------
207 'git-daemon' as inetd server::
208 To set up 'git-daemon' as an inetd service that handles any
209 repository under the whitelisted set of directories, /pub/foo
210 and /pub/bar, place an entry like the following into
211 /etc/inetd all on one line:
212 +
213 ------------------------------------------------
214 git stream tcp nowait nobody /usr/bin/git
215 git daemon --inetd --verbose --export-all
216 /pub/foo /pub/bar
217 ------------------------------------------------
220 'git-daemon' as inetd server for virtual hosts::
221 To set up 'git-daemon' as an inetd service that handles
222 repositories for different virtual hosts, `www.example.com`
223 and `www.example.org`, place an entry like the following into
224 `/etc/inetd` all on one line:
225 +
226 ------------------------------------------------
227 git stream tcp nowait nobody /usr/bin/git
228 git daemon --inetd --verbose --export-all
229 --interpolated-path=/pub/%H%D
230 /pub/www.example.org/software
231 /pub/www.example.com/software
232 /software
233 ------------------------------------------------
234 +
235 In this example, the root-level directory `/pub` will contain
236 a subdirectory for each virtual host name supported.
237 Further, both hosts advertise repositories simply as
238 `git://www.example.com/software/repo.git`. For pre-1.4.0
239 clients, a symlink from `/software` into the appropriate
240 default repository could be made as well.
243 'git-daemon' as regular daemon for virtual hosts::
244 To set up 'git-daemon' as a regular, non-inetd service that
245 handles repositories for multiple virtual hosts based on
246 their IP addresses, start the daemon like this:
247 +
248 ------------------------------------------------
249 git daemon --verbose --export-all
250 --interpolated-path=/pub/%IP/%D
251 /pub/192.168.1.200/software
252 /pub/10.10.220.23/software
253 ------------------------------------------------
254 +
255 In this example, the root-level directory `/pub` will contain
256 a subdirectory for each virtual host IP address supported.
257 Repositories can still be accessed by hostname though, assuming
258 they correspond to these IP addresses.
260 selectively enable/disable services per repository::
261 To enable 'git-archive --remote' and disable 'git-fetch' against
262 a repository, have the following in the configuration file in the
263 repository (that is the file 'config' next to 'HEAD', 'refs' and
264 'objects').
265 +
266 ----------------------------------------------------------------
267 [daemon]
268 uploadpack = false
269 uploadarch = true
270 ----------------------------------------------------------------
273 ENVIRONMENT
274 -----------
275 'git-daemon' will set REMOTE_ADDR to the IP address of the client
276 that connected to it, if the IP address is available. REMOTE_ADDR will
277 be available in the environment of hooks called when
278 services are performed.
