SYSTEMD-STDIO-BRIDGE(1) systemd-stdio-bridge 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_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
[email protected]"). 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.
On success, 0 is returned, a non-zero failure code otherwise.
