             [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-peek-remote clients that are invoked from git-fetch, git-ls-remote, 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.

--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.

--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.

--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.

<directory>

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

upload-pack

This serves git-fetch-pack and git-peek-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.

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-daemon

                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-daemon

                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.
