systemd-stdio-bridge — D-Bus proxy
systemd-stdio-bridge [OPTIONS...]
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).
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"
-h, --help¶--version¶
