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
Print a short help text and exit.
−−version
Print a short version string and exit.
On success, 0 is returned, a non−zero failure code otherwise.
