NAME

       tping - Send echo messages to LAM nodes.

SYNTAX

       tping [-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 statis-
       tics about all roundtrip messages.

EXAMPLES

       tping 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 wipe(1) (although the use of wipe(1)
       is deprecated).
