openSUSE:Leap:42.3 openSUSE Leap 42.3 https://download.opensuse.org/distribution/leap/42.3/repo/oss/ dbus-1 D-Bus Message Bus System D-Bus is a message bus system, a simple way for applications to talk to one another. D-Bus supplies both a system daemon and a per-user-login-session daemon. Also, the message bus is built on top of a general one-to-one message passing framework, which can be used by any two apps to communicate directly (without going through the message bus daemon).
