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=<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 --detach, --port, --listen, --user and --group
82 options.
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.
92 --port=<n>::
93 Listen on an alternative port. Incompatible with '--inetd' option.
95 --init-timeout=<n>::
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).
100 --timeout=<n>::
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
107 zero for no limit.
109 --syslog::
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.
113 --user-path::
114 --user-path=<path>::
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`.
123 --verbose::
124 Log details about the incoming connections and requested files.
126 --reuseaddr::
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.
131 --detach::
132 Detach from the shell. Implies --syslog.
134 --pid-file=<file>::
135 Save the process id in 'file'. Ignored when the daemon
136 is run under `--inetd`.
138 --user=<user>::
139 --group=<group>::
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.
145 +
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.
150 --enable=<service>::
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
156 item.
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
162 are overridable.
164 <directory>::
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.
169 SERVICES
170 --------
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
177 disable them.
179 upload-pack::
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
183 item to `false`.
185 upload-archive::
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`.
190 receive-pack::
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
198 `true`.
200 EXAMPLES
201 --------
202 We assume the following in /etc/services::
203 +
204 ------------
205 $ grep 9418 /etc/services
206 git 9418/tcp # Git Version Control System
207 ------------
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:
214 +
215 ------------------------------------------------
216 git stream tcp nowait nobody /usr/bin/git
217 git daemon --inetd --verbose --export-all
218 /pub/foo /pub/bar
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:
227 +
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
234 /software
235 ------------------------------------------------
236 +
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:
249 +
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 ------------------------------------------------
256 +
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
266 'objects').
267 +
268 ----------------------------------------------------------------
269 [daemon]
270 uploadpack = false
271 uploadarch = true
272 ----------------------------------------------------------------
275 ENVIRONMENT
276 -----------
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.
