22 | DESCRIPTION | |
23 | ----------- | |
62cd033d | 24 | A really simple TCP git daemon that normally listens on port "DEFAULT_GIT_PORT" |
355f5412 JH |
25 | aka 9418. It waits for a connection asking for a service, and will serve |
26 | that service if it is enabled. | |
7fc9d69f | 27 | |
62cd033d LAS |
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 | |
2707da9c | 30 | for export this way (unless the '--export-all' parameter is specified). If you |
0b444cdb | 31 | pass some directory paths as 'git daemon' arguments, you can further restrict |
2707da9c | 32 | the offers to a whitelist comprising of those. |
62cd033d | 33 | |
355f5412 | 34 | By default, only `upload-pack` service is enabled, which serves |
0b444cdb TR |
35 | 'git fetch-pack' and 'git ls-remote' clients, which are invoked |
36 | from 'git fetch', 'git pull', and 'git clone'. | |
355f5412 JH |
37 | |
38 | This is ideally suited for read-only updates, i.e., pulling from | |
39 | git repositories. | |
7fc9d69f | 40 | |
0b444cdb | 41 | An `upload-archive` also exists to serve 'git archive'. |

43 | OPTIONS |
44 | ------- | |
ce335fe0 | 45 | --strict-paths:: |
4dbd1352 AE |
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. | |
0b444cdb | 48 | 'git daemon' will refuse to start when this option is enabled and no |
4dbd1352 AE |
49 | whitelist is specified. |
50 | ||
62b4698e | 51 | --base-path=<path>:: |
b21c31c9 | 52 | Remap all the path requests as relative to the given path. |
0b444cdb | 53 | This is sort of "GIT root" - if you run 'git daemon' with |
b21c31c9 | 54 | '--base-path=/srv/git' on example.com, then if you later try to pull |
0b444cdb | 55 | 'git://example.com/hello.git', 'git daemon' will interpret the path |
603968d2 | 56 | as '/srv/git/hello.git'. |
b21c31c9 | 57 | |
73a7a656 JA |
58 | --base-path-relaxed:: |
59 | If --base-path is enabled and repo lookup fails, with this option | |
0b444cdb | 60 | 'git daemon' will attempt to lookup without prefixing the base path. |
73a7a656 JA |
61 | This is useful for switching to --base-path usage, while still |
62 | allowing the old paths. | |
63 | ||
62b4698e | 64 | --interpolated-path=<pathtemplate>:: |
49ba83fb JL |
65 | To support virtual hosting, an interpolated path template can be |
66 | used to dynamically construct alternate paths. The template | |
dd467629 JL |
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, | |
49ba83fb | 70 | and %D for the absolute path of the named repository. |
dd467629 JL |
71 | After interpolation, the path is validated against the directory |
72 | whitelist. | |
49ba83fb | 73 | |
2707da9c PB |
74 | --export-all:: |
75 | Allow pulling from all directories that look like GIT repositories | |
4dbd1352 | 76 | (have the 'objects' and 'refs' subdirectories), even if they |
2707da9c PB |
77 | do not have the 'git-daemon-export-ok' file. |
78 | ||
62cd033d | 79 | --inetd:: |
bce8230d | 80 | Have the server run as an inetd service. Implies --syslog. |
9cddf56e EFL |
81 | Incompatible with --detach, --port, --listen, --user and --group |
82 | options. | |
dd467629 | 83 | |
62b4698e | 84 | --listen=<host_or_ipaddr>:: |
62854410 MH |
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 | |
dd467629 JL |
87 | is not supported, then --listen=hostname is also not supported and |
88 | --listen must be given an IPv4 address. | |
3a3a29c1 | 89 | Can be given more than once. |
dd467629 | 90 | Incompatible with '--inetd' option. |
7fc9d69f | 91 | |
62b4698e | 92 | --port=<n>:: |
dd467629 | 93 | Listen on an alternative port. Incompatible with '--inetd' option. |
7fc9d69f | 94 | |
62b4698e | 95 | --init-timeout=<n>:: |
2707da9c PB |
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). | |
99 | ||
62b4698e | 100 | --timeout=<n>:: |
2707da9c | 101 | Timeout for specific client sub-requests. This includes the time |
62854410 MH |
102 | it takes for the server to process the sub-request and the time spent |
103 | waiting for the next client's request. | |
2707da9c | 104 | |
62b4698e | 105 | --max-connections=<n>:: |
3bd62c21 SB |
106 | Maximum number of concurrent clients, defaults to 32. Set it to |
107 | zero for no limit. | |
108 | ||
9048fe1c PB |
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. | |
112 | ||
3240240f | 113 | --user-path:: |
62b4698e | 114 | --user-path=<path>:: |
4fce51cf | 115 | Allow {tilde}user notation to be used in requests. When |
603968d2 | 116 | specified with no parameter, requests to |
4fce51cf | 117 | git://host/{tilde}alice/foo is taken as a request to access |
603968d2 JH |
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`. | |
122 | ||
b5cf3c8b PB |
123 | --verbose:: |
124 | Log details about the incoming connections and requested files. | |
125 | ||
6c35119a ML |
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. | |
130 | ||
131 | --detach:: | |
132 | Detach from the shell. Implies --syslog. | |
133 | ||
62b4698e | 134 | --pid-file=<file>:: |
bdd73795 JH |
135 | Save the process id in 'file'. Ignored when the daemon |
136 | is run under `--inetd`. | |
6c35119a | 137 | |
62b4698e ŠN |
138 | --user=<user>:: |
139 | --group=<group>:: | |
678dac6b TS |
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 | |
0b444cdb | 148 | 'git daemon' if needed. |
678dac6b | 149 | |
62b4698e ŠN |
150 | --enable=<service>:: |
151 | --disable=<service>:: | |
355f5412 JH |
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 | |
62854410 | 155 | repository enables the service with a configuration |
355f5412 JH |
156 | item. |
157 | ||
62b4698e ŠN |
158 | --allow-override=<service>:: |
159 | --forbid-override=<service>:: | |
355f5412 JH |
160 | Allow/forbid overriding the site-wide default with per |
161 | repository configuration. By default, all the services | |
162 | are overridable. | |
163 | ||
4dbd1352 AE |
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. | |
168 | ||
355f5412 JH |
169 | SERVICES |
170 | -------- | |
171 | ||
bdd73795 JH |
172 | These services can be globally enabled/disabled using the |
173 | command line options of this command. If a finer-grained | |
0b444cdb | 174 | control is desired (e.g. to allow 'git archive' to be run |
bdd73795 JH |
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. | |
178 | ||
355f5412 | 179 | upload-pack:: |
0b444cdb | 180 | This serves 'git fetch-pack' and 'git ls-remote' |
355f5412 JH |
181 | clients. It is enabled by default, but a repository can |
182 | disable it by setting `daemon.uploadpack` configuration | |
183 | item to `false`. | |
184 | ||
e2b1d1cc | 185 | upload-archive:: |
0b444cdb | 186 | This serves 'git archive --remote'. It is disabled by |
bdd73795 | 187 | default, but a repository can enable it by setting |
74190d23 | 188 | `daemon.uploadarch` configuration item to `true`. |
bdd73795 JH |
189 | |
190 | receive-pack:: | |
0b444cdb | 191 | This serves 'git send-pack' clients, allowing anonymous |
bdd73795 JH |
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 | -------- | |

0b444cdb TR |
209 | 'git daemon' as inetd server:: |
210 | To set up 'git daemon' as an inetd service that handles any | |
49ba83fb JL |
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 | ------------------------------------------------ | |
963a653f JN |
216 | git stream tcp nowait nobody /usr/bin/git |
217 | git daemon --inetd --verbose --export-all | |

221 | ||
0b444cdb TR |
222 | 'git daemon' as inetd server for virtual hosts:: |
223 | To set up 'git daemon' as an inetd service that handles | |
49ba83fb JL |
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 | ------------------------------------------------ | |
963a653f JN |
229 | git stream tcp nowait nobody /usr/bin/git |
230 | git daemon --inetd --verbose --export-all | |
49ba83fb JL |
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. | |
243 | ||
244 | ||
0b444cdb TR |
245 | 'git daemon' as regular daemon for virtual hosts:: |
246 | To set up 'git daemon' as a regular, non-inetd service that | |
dd467629 JL |
247 | handles repositories for multiple virtual hosts based on |
248 | their IP addresses, start the daemon like this: | |
249 | + | |
250 | ------------------------------------------------ | |
963a653f | 251 | git daemon --verbose --export-all |
dd467629 JL |
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. | |
261 | ||
f368f5a6 | 262 | selectively enable/disable services per repository:: |
0b444cdb | 263 | To enable 'git archive --remote' and disable 'git fetch' against |
f368f5a6 JH |
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'). | |

275 | ENVIRONMENT |
276 | ----------- | |
0b444cdb | 277 | 'git daemon' will set REMOTE_ADDR to the IP address of the client |
53ffb878 JH |
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. | |
