# probes::EchoPing.pm(3)

an echoping(1) probe for SmokePing

## NAME

probes::EchoPing - an [echoping(1)](/echoping/1.md) probe for SmokePing

## OVERVIEW

Measures TCP or UDP echo (port 7) roundtrip times for SmokePing. Can also be  used as a base class for other [*echoping*(1)](/echoping/1.md) probes.

## SYNOPSYS

```
 *** Probes ***
 + EchoPing
```

```
 binary = /usr/bin/echoping # default value
```

```
 *** Targets ***
```

```
 probe = EchoPing
 forks = 10
```

```
 menu = Top
 title = Top Menu
 remark = Top Menu Remark
```

```
 + PROBE_CONF
```

```
 # none of these are mandatory
 timeout = 1
 waittime = 1
 udp = no
 size = 510
 tos = 0xa0
 priority = 6
```

```
 + First
 menu = First
 title = First Target
 host = router.example.com
```

```
 # PROBE_CONF can be overridden here
 ++ PROBE_CONF
 size = 300
```

## DESCRIPTION

Supported probe-specific variables:

- binary

  The location of your echoping binary.

- forks

  The number of concurrent processes to be run. See *probes::basefork*(3pm)  for details.

Supported target-level probe variables  (see [*echoping*(1)](/echoping/1.md) for details of the options):

- timeout

  The "-t" [*echoping*(1)](/echoping/1.md) option.

- waittime

  The "-w" [*echoping*(1)](/echoping/1.md) option.

- size

  The "-s" [*echoping*(1)](/echoping/1.md) option.

- udp

  The "-u" [*echoping*(1)](/echoping/1.md) option. Values other than '0' and 'no' enable UDP.

- fill

  The "-f" [*echoping*(1)](/echoping/1.md) option.

- priority

  The "-p" [*echoping*(1)](/echoping/1.md) option.

- tos

  The "-P" [*echoping*(1)](/echoping/1.md) option.

- ipversion

  The IP protocol used. Possible values are "4" and "6".  Passed to [*echoping*(1)](/echoping/1.md) as the "-4" or "-6" options.

- extraopts

  Any extra options specified here will be passed unmodified to [*echoping*(1)](/echoping/1.md).

## BUGS

Should we test the availability of the service at startup? After that it's too late to complain.

The location of the echoping binary should probably be a global variable instead of a probe-specific one. As things are, every EchoPing -derived probe  has to declare it if the default (/usr/bin/echoping) isn't correct.
