Sysbox: devping

Usage: devping [OPTION]... [-T timeout] DEVNAME...

Ping a device. This is a diagnostic tool, used to determine whether the device is still alive. A broken device may not answer to the devping tool. Note that, this tool performs a low-level diagnostic, and it does not mean that the device (or service) is not locked on higher levels. Only the Device Framework is affected in the test. On success nothing will be printed onto the output.

Options:

Examples:

$ devping vfs tcpip
$ devping -v tmpfs
devping: tmpfs: get device MsgPort from registry ("run/dev/tmpfs")
devping: tmpfs: pinging with 5000 msec timeout
devping: tmpfs: message sent
devping: tmpfs: ping successful
