systemd systemd-stdio-bridge 1 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_fds3. 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-bus3 uses systemd-stdio-bridge to forward D-Bus connections over ssh1, or to connect to the bus of a different user, see sd_bus_set_address3. The following options are understood: -p PATH --bus-path=PATH Path to the bus address. Default: unix:path=/run/dbus/system_bus_socket On success, 0 is returned, a non-zero failure code otherwise. dbus-daemon1 dbus-broker1 D-Bus systemd1
