# tping(1)

Send echo messages to LAM nodes.

## 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)](/ping/8.md) 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)](/lamhalt/1.md) or [lamwipe(1)](/lamwipe/1.md) (although the use of [lamwipe(1)](/lamwipe/1.md) is deprecated).
