It waits for a connection asking for a service, and will serve 26that service if it is enabled. 27 28It verifies that the directory has the magic file "git-daemon-export-ok", and 29it will refuse to export any git directory that hasn't explicitly been marked 30for export this way (unless the '--export-all' parameter is specified). If you 31pass some directory paths as 'git-daemon' arguments, you can further restrict 32the offers to a whitelist comprising of those. 33 34By default, only `upload-pack` service is enabled, which serves 35'git-fetch-pack' and 'git-ls-remote' clients, which are invoked 36from 'git-fetch', 'git-pull', and 'git-clone'. 37 38This is ideally suited for read-only updates, i.e., pulling from 39git repositories. 40 41An `upload-archive` also exists to serve 'git-archive'. 42 43OPTIONS 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. 50 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'. 57 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. 63 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. 73 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. 78 79--inetd:: 80 Have the server run as an inetd service. Implies --syslog. 81 Incompatible with --port, --listen, --user and --group options. 82 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. 89 90--port=n:: 91 Listen on an alternative port. Incompatible with '--inetd' option. 92 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). 97 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. 102 103--max-connections:: 104 Maximum number of concurrent clients, defaults to 32. Set it to 105 zero for no limit. 106 107--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. 110 111--user-path:: 112--user-path=path:: 113 Allow ~user notation to be used in requests. When 114 specified with no parameter, requests to 115 git://host/~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`. 120 121--verbose:: 122 Log details about the incoming connections and requested files. 123 124--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. 128 129--detach:: 130 Detach from the shell. Implies --syslog. 131 132--pid-file=file:: 133 Save the process id in 'file'. Ignored when the daemon 134 is run under `--inetd`. 135 136--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+ 144Giving these options is an error when used with `--inetd`; use 145the facility of inet daemon to achieve the same before spawning 146'git-daemon' if needed. 147 148--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. 155 156--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. 161 162<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. 166 167SERVICES 168-------- 169 170These services can be globally enabled/disabled using the 171command line options of this command. If a finer-grained 172control is desired (e.g. to allow 'git-archive' to be run 173against only in a few selected repositories the daemon serves), 174the per-repository configuration file can be used to enable or 175disable them. 176 177upload-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`. 182 183upload-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`. 187 188receive-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`. 197 198EXAMPLES 199-------- 200We assume the following in /etc/services:: 201+ 202------------ 203$ grep 9418 /etc/services 204git 9418/tcp # Git Version Control System 205------------ 206 207'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------------------------------------------------ 218 219 220'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+ 235In this example, the root-level directory `/pub` will contain 236a subdirectory for each virtual host name supported. 237Further, both hosts advertise repositories simply as 238`git://www.example.com/software/repo.git`. For pre-1.4.0 239clients, a symlink from `/software` into the appropriate 240default repository could be made as well. 241 242 243'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+ 255In this example, the root-level directory `/pub` will contain 256a subdirectory for each virtual host IP address supported. 257Repositories can still be accessed by hostname though, assuming 258they correspond to these IP addresses. 259 260selectively 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---------------------------------------------------------------- 271 272 273ENVIRONMENT 274----------- 275'git-daemon' will set REMOTE_ADDR to the IP address of the client 276that connected to it, if the IP address is available. REMOTE_ADDR will 277be available in the environment of hooks called when 278services are performed. 279 280 281 282Author 283------ 284Written by Linus Torvalds <torvalds@osdl.org>, YOSHIFUJI Hideaki 285<yoshfuji@linux-ipv6.org> and the git-list <git@vger.kernel.org> 286 287Documentation 288-------------- 289Documentation by Junio C Hamano and the git-list <git@vger.kernel.org>. 290 291GIT 292--- 293Part of the linkgit:git[1] suite
