NAME

       tping - Send echo messages to LAM nodes.

SYNOPSIS

       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 statistics 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 lamwipe(1) (although the use
       of lamwipe(1) is deprecated).
