TPING(1) LAM COMMANDS TPING(1)NAMEtping - Send echo messages to LAM nodes.
SYNTAXtping [-hv] [-c <count>] [-d <delay>] [-l <length>] <nodes>
OPTIONS-h Print the command help menu.
-v Turn OFF verbose mode.
-c <count> Send <count> messages.
-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.
EXAMPLEStping h
Echo messages to the local node.
tping-v n7 -l 1000 -c 10
Echo 1000 byte messages to node 7. Stay silent while working.
Stop after 10 roundtrips and report statistics.
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 lamhalt(1) or lamwipe(1) (although the use of lamwipe(1) is
deprecated).
