It waits for a connection asking for a service, and will serve 25that service if it is enabled. 26 27It verifies that the directory has the magic file "git-daemon-export-ok", and 28it will refuse to export any git directory that hasn't explicitly been marked 29for export this way (unless the '--export-all' parameter is specified). If you 30pass some directory paths as 'git-daemon' arguments, you can further restrict 31the offers to a whitelist comprising of those. 32 33By default, only `upload-pack` service is enabled, which serves 34`git-fetch-pack` and `git-ls-remote` clients, which are invoked 35from `git-fetch`, `git-pull`, and `git-clone`. 36 37This is ideally suited for read-only updates, i.e., pulling from 38git repositories. 39 40An `upload-archive` also exists to serve `git-archive`. 41 42OPTIONS 43------- 44--strict-paths:: 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. 49 50--base-path:: 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'. 56 57--base-path-relaxed:: 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. 62 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 71 whitelist. 72 73--export-all:: 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. 77 78--inetd:: 79 Have the server run as an inetd service. Implies --syslog. 80 Incompatible with --port, --listen, --user and --group options. 81 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. 88 89--port=n:: 90 Listen on an alternative port. Incompatible with '--inetd' option. 91 92--init-timeout:: 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). 96 97--timeout:: 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. 101 102--syslog:: 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. 105 106--user-path:: 107--user-path=path:: 108 Allow ~user notation to be used in requests. When 109 specified with no parameter, requests to 110 git://host/~alice/foo is taken as a request to access 111 'foo' repository in the home directory of user `alice`. 112 If `--user-path=path` is specified, the same request is 113 taken as a request to access `path/foo` repository in 114 the home directory of user `alice`. 115 116--verbose:: 117 Log details about the incoming connections and requested files. 118 119--reuseaddr:: 120 Use SO_REUSEADDR when binding the listening socket. 121 This allows the server to restart without waiting for 122 old connections to time out. 123 124--detach:: 125 Detach from the shell. Implies --syslog. 126 127--pid-file=file:: 128 Save the process id in 'file'. Ignored when the daemon 129 is run under `--inetd`. 130 131--user=user:: 132--group=group:: 133 Change daemon's uid and gid before entering the service loop. 134 When only `--user` is given without `--group`, the 135 primary group ID for the user is used. The values of 136 the option are given to `getpwnam(3)` and `getgrnam(3)` 137 and numeric IDs are not supported. 138+ 139Giving these options is an error when used with `--inetd`; use 140the facility of inet daemon to achieve the same before spawning 141`git-daemon` if needed. 142 143--enable=service:: 144--disable=service:: 145 Enable/disable the service site-wide per default. Note 146 that a service disabled site-wide can still be enabled 147 per repository if it is marked overridable and the 148 repository enables the service with an configuration 149 item. 150 151--allow-override=service:: 152--forbid-override=service:: 153 Allow/forbid overriding the site-wide default with per 154 repository configuration. By default, all the services 155 are overridable. 156 157<directory>:: 158 A directory to add to the whitelist of allowed directories. Unless 159 --strict-paths is specified this will also include subdirectories 160 of each named directory. 161 162SERVICES 163-------- 164 165These services can be globally enabled/disabled using the 166command line options of this command. If a finer-grained 167control is desired (e.g. to allow `git-archive` to be run 168against only in a few selected repositories the daemon serves), 169the per-repository configuration file can be used to enable or 170disable them. 171 172upload-pack:: 173 This serves `git-fetch-pack` and `git-ls-remote` 174 clients. It is enabled by default, but a repository can 175 disable it by setting `daemon.uploadpack` configuration 176 item to `false`. 177 178upload-archive:: 179 This serves `git-archive --remote`. It is disabled by 180 default, but a repository can enable it by setting 181 `daemon.uploadarch` configuration item to `true`. 182 183receive-pack:: 184 This serves `git-send-pack` clients, allowing anonymous 185 push. It is disabled by default, as there is _no_ 186 authentication in the protocol (in other words, anybody 187 can push anything into the repository, including removal 188 of refs). This is solely meant for a closed LAN setting 189 where everybody is friendly. This service can be 190 enabled by `daemon.receivepack` configuration item to 191 `true`. 192 193EXAMPLES 194-------- 195We assume the following in /etc/services:: 196+ 197------------ 198$ grep 9418 /etc/services 199git 9418/tcp # Git Version Control System 200------------ 201 202git-daemon as inetd server:: 203 To set up `git-daemon` as an inetd service that handles any 204 repository under the whitelisted set of directories, /pub/foo 205 and /pub/bar, place an entry like the following into 206 /etc/inetd all on one line: 207+ 208------------------------------------------------ 209 git stream tcp nowait nobody /usr/bin/git-daemon 210 git-daemon --inetd --verbose --export-all 211 /pub/foo /pub/bar 212------------------------------------------------ 213 214 215git-daemon as inetd server for virtual hosts:: 216 To set up `git-daemon` as an inetd service that handles 217 repositories for different virtual hosts, `www.example.com` 218 and `www.example.org`, place an entry like the following into 219 `/etc/inetd` all on one line: 220+ 221------------------------------------------------ 222 git stream tcp nowait nobody /usr/bin/git-daemon 223 git-daemon --inetd --verbose --export-all 224 --interpolated-path=/pub/%H%D 225 /pub/www.example.org/software 226 /pub/www.example.com/software 227 /software 228------------------------------------------------ 229+ 230In this example, the root-level directory `/pub` will contain 231a subdirectory for each virtual host name supported. 232Further, both hosts advertise repositories simply as 233`git://www.example.com/software/repo.git`. For pre-1.4.0 234clients, a symlink from `/software` into the appropriate 235default repository could be made as well. 236 237 238git-daemon as regular daemon for virtual hosts:: 239 To set up `git-daemon` as a regular, non-inetd service that 240 handles repositories for multiple virtual hosts based on 241 their IP addresses, start the daemon like this: 242+ 243------------------------------------------------ 244 git-daemon --verbose --export-all 245 --interpolated-path=/pub/%IP/%D 246 /pub/192.168.1.200/software 247 /pub/10.10.220.23/software 248------------------------------------------------ 249+ 250In this example, the root-level directory `/pub` will contain 251a subdirectory for each virtual host IP address supported. 252Repositories can still be accessed by hostname though, assuming 253they correspond to these IP addresses. 254 255selectively enable/disable services per repository:: 256 To enable `git-archive --remote` and disable `git-fetch` against 257 a repository, have the following in the configuration file in the 258 repository (that is the file 'config' next to 'HEAD', 'refs' and 259 'objects'). 260+ 261---------------------------------------------------------------- 262 [daemon] 263 uploadpack = false 264 uploadarch = true 265---------------------------------------------------------------- 266 267 268Author 269------ 270Written by Linus Torvalds <torvalds@osdl.org>, YOSHIFUJI Hideaki 271<yoshfuji@linux-ipv6.org> and the git-list <git@vger.kernel.org> 272 273Documentation 274-------------- 275Documentation by Junio C Hamano and the git-list <git@vger.kernel.org>. 276 277GIT 278--- 279Part of the linkgit:git[1] suite
