SYNTAX

OPTIONS
-h
Print the command help menu.
-v
-c <count>
-d <delay>
Delay <delay> seconds between each message.
-l <length>
Each message is <length> bytes long.
DESCRIPTION
The
tping
command sends messages to, and collects replies from,
a list of nodes, via the LAM echo server.
It is similar to the UNIX ping(8) command, and is used as a quick
diagnosis of the LAM network.
Unless options are specified,
tping
sends a 1 byte message an infinite number of times,
displaying the roundtrip time of each message as it completes,
with a delay of 1 second between roundtrips.
After the loop is broken (with keyboard interrupt, eg: ^C),
tping
prints statistics about all roundtrip messages.
EXAMPLES
BUGS
There is no built-in timeout and
tping
will wait forever to receive an echo.
If no echo is received, due to a dead link or node,
tping
hangs.
Stop the process with a keyboard suspend signal (eg: ^Z) and
terminate LAM with wipe(1).
