systemd-stdio-bridge — D-Bus proxy
systemd-stdio-bridge [OPTIONS...]
systemd-stdio-bridge implements a proxy for a D-Bus endpoint. It expects to
receive an open connection to a bus when started, and will also connect to a (different) bus as a
client. It will then act as a server on the first connection, and forward messages between the two
busses. 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¶
