SYSTEMD-STDIO-BRIDGE(1) systemd-stdio-bridge SYSTEMD-STDIO-BRIDGE(1)
NAME
systemd-stdio-bridge - D-Bus proxy
SYNOPSIS
systemd-stdio-bridge [OPTIONS...]
DESCRIPTION
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).
OPTIONS
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.
EXIT STATUS
On success, 0 is returned, a non-zero failure code otherwise.
