NAME

       systemd-stdio-bridge - D-Bus proxy

SYNOPSIS

       systemd-stdio-bridge [OPTIONS...]

DESCRIPTION

       systemd-stdio-bridge implements a proxy between STDIN/STDOUT and a D-Bus bus. It expects
       to receive an open connection via STDIN/STDOUT when started, and will create a new
       connection to the specified bus. It will then forward messages between the two
       connections. This program is suitable for socket activation: the first connection may be a
       pipe or a socket and must be passed as either standard input, or as an open file
       descriptor according to the protocol described in sd_listen_fds(3). The second connection
       will be made by default to the local system bus, but this can be influenced by the --user,
       --system, --machine=, and --bus-path= options described below.

       sd-bus(3) uses systemd-stdio-bridge to forward D-Bus connections over ssh(1), or to
       connect to the bus of a different user, see sd_bus_set_address(3).

OPTIONS

       The following options are understood:

       --user
           Talk to the service manager of the calling user, rather than the service manager of
           the system.

       --system
           Talk to the service manager of the system. This is the implied default.

       -M, --machine=
           Execute operation on a local container. Specify a container name to connect to,
           optionally prefixed by a user name to connect as and a separating "@" character. If
           the special string ".host" is used in place of the container name, a connection to the
           local system is made (which is useful to connect to a specific user's user bus:
           "--user --machine=lennart@.host"). If the "@" syntax is not used, the connection is
           made as root user. If the "@" syntax is used either the left hand side or the right
           hand side may be omitted (but not both) in which case the local user name and ".host"
           are implied.

       -p PATH, --bus-path=PATH
           Path to the bus address. Default: "unix:path=/run/dbus/system_bus_socket"

           Added in version 251.

       -h, --help
           Print a short help text and exit.

       --version
           Print a short version string and exit.

EXIT STATUS

       On success, 0 is returned, a non-zero failure code otherwise.
