git-daemon(1) ============= NAME ---- git-daemon - A really simple server for git repositories SYNOPSIS -------- [verse] 'git daemon' [--verbose] [--syslog] [--export-all] [--timeout=n] [--init-timeout=n] [--max-connections=n] [--strict-paths] [--base-path=path] [--base-path-relaxed] [--user-path | --user-path=path] [--interpolated-path=pathtemplate] [--reuseaddr] [--detach] [--pid-file=file] [--enable=service] [--disable=service] [--allow-override=service] [--forbid-override=service] [--inetd | [--listen=host_or_ipaddr] [--port=n] [--user=user [--group=group]] [directory...] DESCRIPTION ----------- A really simple TCP git daemon that normally listens on port "DEFAULT_GIT_PORT" aka 9418. It waits for a connection asking for a service, and will serve that service if it is enabled. It verifies that the directory has the magic file "git-daemon-export-ok", and it will refuse to export any git directory that hasn't explicitly been marked for export this way (unless the '--export-all' parameter is specified). If you pass some directory paths as 'git-daemon' arguments, you can further restrict the offers to a whitelist comprising of those. By default, only `upload-pack` service is enabled, which serves 'git-fetch-pack' and 'git-ls-remote' clients, which are invoked from 'git-fetch', 'git-pull', and 'git-clone'. This is ideally suited for read-only updates, i.e., pulling from git repositories. An `upload-archive` also exists to serve 'git-archive'. OPTIONS ------- --strict-paths:: Match paths exactly (i.e. don't allow "/foo/repo" when the real path is "/foo/repo.git" or "/foo/repo/.git") and don't do user-relative paths. 'git-daemon' will refuse to start when this option is enabled and no whitelist is specified. --base-path:: Remap all the path requests as relative to the given path. This is sort of "GIT root" - if you run 'git-daemon' with '--base-path=/srv/git' on example.com, then if you later try to pull 'git://example.com/hello.git', 'git-daemon' will interpret the path as '/srv/git/hello.git'. --base-path-relaxed:: If --base-path is enabled and repo lookup fails, with this option 'git-daemon' will attempt to lookup without prefixing the base path. This is useful for switching to --base-path usage, while still allowing the old paths. --interpolated-path=pathtemplate:: To support virtual hosting, an interpolated path template can be used to dynamically construct alternate paths. The template supports %H for the target hostname as supplied by the client but converted to all lowercase, %CH for the canonical hostname, %IP for the server's IP address, %P for the port number, and %D for the absolute path of the named repository. After interpolation, the path is validated against the directory whitelist. --export-all:: Allow pulling from all directories that look like GIT repositories (have the 'objects' and 'refs' subdirectories), even if they do not have the 'git-daemon-export-ok' file. --inetd:: Have the server run as an inetd service. Implies --syslog. Incompatible with --port, --listen, --user and --group options. --listen=host_or_ipaddr:: Listen on an a specific IP address or hostname. IP addresses can be either an IPv4 address or an IPV6 address if supported. If IPv6 is not supported, then --listen=hostname is also not supported and --listen must be given an IPv4 address. Incompatible with '--inetd' option. --port=n:: Listen on an alternative port. Incompatible with '--inetd' option. --init-timeout:: Timeout between the moment the connection is established and the client request is received (typically a rather low value, since that should be basically immediate). --timeout:: Timeout for specific client sub-requests. This includes the time it takes for the server to process the sub-request and time spent waiting for next client's request. --max-connections:: Maximum number of concurrent clients, defaults to 32. Set it to zero for no limit. --syslog:: Log to syslog instead of stderr. Note that this option does not imply --verbose, thus by default only error conditions will be logged. --user-path:: --user-path=path:: Allow ~user notation to be used in requests. When specified with no parameter, requests to git://host/~alice/foo is taken as a request to access 'foo' repository in the home directory of user `alice`. If `--user-path=path` is specified, the same request is taken as a request to access `path/foo` repository in the home directory of user `alice`. --verbose:: Log details about the incoming connections and requested files. --reuseaddr:: Use SO_REUSEADDR when binding the listening socket. This allows the server to restart without waiting for old connections to time out. --detach:: Detach from the shell. Implies --syslog. --pid-file=file:: Save the process id in 'file'. Ignored when the daemon is run under `--inetd`. --user=user:: --group=group:: Change daemon's uid and gid before entering the service loop. When only `--user` is given without `--group`, the primary group ID for the user is used. The values of the option are given to `getpwnam(3)` and `getgrnam(3)` and numeric IDs are not supported. + Giving these options is an error when used with `--inetd`; use the facility of inet daemon to achieve the same before spawning 'git-daemon' if needed. --enable=service:: --disable=service:: Enable/disable the service site-wide per default. Note that a service disabled site-wide can still be enabled per repository if it is marked overridable and the repository enables the service with an configuration item. --allow-override=service:: --forbid-override=service:: Allow/forbid overriding the site-wide default with per repository configuration. By default, all the services are overridable. :: A directory to add to the whitelist of allowed directories. Unless --strict-paths is specified this will also include subdirectories of each named directory. SERVICES -------- These services can be globally enabled/disabled using the command line options of this command. If a finer-grained control is desired (e.g. to allow 'git-archive' to be run against only in a few selected repositories the daemon serves), the per-repository configuration file can be used to enable or disable them. upload-pack:: This serves 'git-fetch-pack' and 'git-ls-remote' clients. It is enabled by default, but a repository can disable it by setting `daemon.uploadpack` configuration item to `false`. upload-archive:: This serves 'git-archive --remote'. It is disabled by default, but a repository can enable it by setting `daemon.uploadarch` configuration item to `true`. receive-pack:: This serves 'git-send-pack' clients, allowing anonymous push. It is disabled by default, as there is _no_ authentication in the protocol (in other words, anybody can push anything into the repository, including removal of refs). This is solely meant for a closed LAN setting where everybody is friendly. This service can be enabled by `daemon.receivepack` configuration item to `true`. EXAMPLES -------- We assume the following in /etc/services:: + ------------ $ grep 9418 /etc/services git 9418/tcp # Git Version Control System ------------ 'git-daemon' as inetd server:: To set up 'git-daemon' as an inetd service that handles any repository under the whitelisted set of directories, /pub/foo and /pub/bar, place an entry like the following into /etc/inetd all on one line: + ------------------------------------------------ git stream tcp nowait nobody /usr/bin/git git daemon --inetd --verbose --export-all /pub/foo /pub/bar ------------------------------------------------ 'git-daemon' as inetd server for virtual hosts:: To set up 'git-daemon' as an inetd service that handles repositories for different virtual hosts, `www.example.com` and `www.example.org`, place an entry like the following into `/etc/inetd` all on one line: + ------------------------------------------------ git stream tcp nowait nobody /usr/bin/git git daemon --inetd --verbose --export-all --interpolated-path=/pub/%H%D /pub/www.example.org/software /pub/www.example.com/software /software ------------------------------------------------ + In this example, the root-level directory `/pub` will contain a subdirectory for each virtual host name supported. Further, both hosts advertise repositories simply as `git://www.example.com/software/repo.git`. For pre-1.4.0 clients, a symlink from `/software` into the appropriate default repository could be made as well. 'git-daemon' as regular daemon for virtual hosts:: To set up 'git-daemon' as a regular, non-inetd service that handles repositories for multiple virtual hosts based on their IP addresses, start the daemon like this: + ------------------------------------------------ git daemon --verbose --export-all --interpolated-path=/pub/%IP/%D /pub/192.168.1.200/software /pub/10.10.220.23/software ------------------------------------------------ + In this example, the root-level directory `/pub` will contain a subdirectory for each virtual host IP address supported. Repositories can still be accessed by hostname though, assuming they correspond to these IP addresses. selectively enable/disable services per repository:: To enable 'git-archive --remote' and disable 'git-fetch' against a repository, have the following in the configuration file in the repository (that is the file 'config' next to 'HEAD', 'refs' and 'objects'). + ---------------------------------------------------------------- [daemon] uploadpack = false uploadarch = true ---------------------------------------------------------------- Author ------ Written by Linus Torvalds , YOSHIFUJI Hideaki and the git-list Documentation -------------- Documentation by Junio C Hamano and the git-list .
