NAME

6       systemd-stdio-bridge - D-Bus proxy
7

SYNOPSIS

9       systemd-stdio-bridge [OPTIONS...]
10

DESCRIPTION

12       systemd-stdio-bridge implements a proxy between STDIN/STDOUT and a
13       D-Bus bus. It expects to receive an open connection via STDIN/STDOUT
14       when started, and will create a new connection to the specified bus. It
15       will then forward messages between the two connections. This program is
16       suitable for socket activation: the first connection may be a pipe or a
17       socket and must be passed as either standard input, or as an open file
18       descriptor according to the protocol described in sd_listen_fds(3). The
19       second connection will be made by default to the local system bus, but
20       this can be influenced by the --user, --system, --machine=, and
21       --bus-path= options described below.
22
23       sd-bus(3) uses systemd-stdio-bridge to forward D-Bus connections over
24       ssh(1), or to connect to the bus of a different user, see
25       sd_bus_set_address(3).
26

OPTIONS

28       The following options are understood:
29
30       --user
31           Talk to the service manager of the calling user, rather than the
32           service manager of the system.
33
34       --system
35           Talk to the service manager of the system. This is the implied
36           default.
37
38       -M, --machine=
39           Execute operation on a local container. Specify a container name to
40           connect to, optionally prefixed by a user name to connect as and a
41           separating "@" character. If the special string ".host" is used in
42           place of the container name, a connection to the local system is
43           made (which is useful to connect to a specific user's user bus:
44           "--user --machine=lennart@.host"). If the "@" syntax is not used,
45           the connection is made as root user. If the "@" syntax is used
46           either the left hand side or the right hand side may be omitted
47           (but not both) in which case the local user name and ".host" are
48           implied.
49
50       -p PATH, --bus-path=PATH
51           Path to the bus address. Default:
52           "unix:path=/run/dbus/system_bus_socket"
53
54       -h, --help
55           Print a short help text and exit.
56
57       --version
58           Print a short version string and exit.
59

EXIT STATUS

61       On success, 0 is returned, a non-zero failure code otherwise.
