NAME

6       tping - Send echo messages to LAM nodes.
7

SYNTAX

9       tping [-hv] [-c <count>] [-d <delay>] [-l <length>] <nodes>
10

OPTIONS

12       -h            Print the command help menu.
13
14       -v            Turn OFF verbose mode.
15
16       -c <count>    Send <count> messages.
17
18       -d <delay>    Delay <delay> seconds between each message.
19
20       -l <length>   Each message is <length> bytes long.
21

DESCRIPTION

23       The  tping command sends messages to, and collects replies from, a list
24       of nodes, via the LAM echo server.  It is similar to the  UNIX  ping(8)
25       command, and is used as a quick diagnosis of the LAM network.
26
27       Unless  options are specified, tping sends a 1 byte message an infinite
28       number of times, displaying the roundtrip time of each  message  as  it
29       completes, with a delay of 1 second between roundtrips.  After the loop
30       is broken (with keyboard interrupt, eg: ^C),  tping  prints  statistics
31       about all roundtrip messages.
32

EXAMPLES

34       tping h
35           Echo messages to the local node.
36
37       tping -v n7 -l 1000 -c 10
38           Echo  1000  byte  messages  to  node 7.  Stay silent while working.
39           Stop after 10 roundtrips and report statistics.
40

BUGS

42       There is no built-in timeout and tping will wait forever to receive  an
43       echo.  If no echo is received, due to a dead link or node, tping hangs.
44       Stop the process with a keyboard suspend signal (eg: ^Z) and  terminate
45       LAM  with  lamhalt(1)  or lamwipe(1) (although the use of lamwipe(1) is
46       deprecated).
