tping(1)


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).
