 ===== uBus - IPC/RPC =====
-uBus is the interconnect system used by most services running on a //LEDE// setup. Services can connect to the bus and provide methods that can be called by other services or clients.
+uBus is the interconnect system used by most services running on a //OpenWrt// setup. Services can connect to the bus and provide methods that can be called by other services or clients.
-There is a CLI that can be used to communicate with services on the bus.
+See [[docs:techref:ubus|uBus Technical Reference]]
-<code>
-root@lede:/# ubus
-Usage: ubus [<options>] <command> [arguments...]
-Options:
--s <socket>:            Set the unix domain socket to connect to
--t <timeout>:           Set the timeout (in seconds) for a command to complete
--S:                     Use simplified output (for scripts)
--v:                     More verbose output
-Commands:
-- list [<path>]                 List objects
-- call <path> <method> [<message>]      Call an object method
-- listen [<path>...]                    Listen for events
-- send <type> [<message>]               Send an event
-- wait_for <object> [<object>...]       Wait for multiple objects to appear on ubus
-</code>
-To find out which services are currently running on the bus simply use the list command. This will show a complete list.
-<code>
-root@lede:/# ubus list
-dhcp
-log
-network
-network.device
-network.interface
-network.interface.loopback
-network.interface.wan
-network.interface.wan6
-network.wireless
-service
-system
-</code>
-To find out which methods a specific service provides also use the list command but add a few more parameters to see a complete list
-<code>
-root@OpenWrt:/# ubus -v list system
-'system' @6b093875
-        "board":{}
-        "info":{}
-        "upgrade":{}
-        "watchdog":{"frequency":"Integer","timeout":"Integer","stop":"Boolean"}
-        "signal":{"pid":"Integer","signum":"Integer"}
-</code>
-You can now call a remote method and receive a reply. A reply may be a simple integer return code or a more complete reply. Internally the bus uses a blob format, the CLI conveniently converts this to JSON.
-<code>
-root@lede:/# ubus call system board
-{
-        "kernel": "4.4.6",
-        "hostname": "lede",
-        "system": "MIPS Malta",
-        "release": {
-                "distribution": "LEDE",
-                "version": "HEAD",
-                "revision": "3",
-                "codename": "designated_driver",
-                "target": "malta\/le",
-                "description": "LEDE Designated Driver 3"
-        }
-}
-</code>
-You can call a method and pass it some parameters by simply appending a JSON structure to the CLI command.
-<code>
-root@lede:/# ubus call system signal '{ "pid": 123, "signum": 9 }'
-root@lede:/# echo $?
-</code>
