Network connection detection

Factual Questions
1

I have googled a bit and whas unable to find what I was looking for. I am trying to locate some kind of a simple network monitor that would allow me to plug in an IP addy and it would ping every 30 seconds or so and be able to alert when a connection dropped. Logging capability would be cool but just something that would chirp at me or something if a ping did not return. Only needs to handle 1 address so I hope its not asking too much to find a freeware utility that does it.

Thanks.

Neotrace is probably more than you need, but it will do it. They used to offer a limited-function unlimited-use free trial version. Worth looking into.

Try MRTG:

I don’t know about the playing a sound part, but poke around the site, I have to imagine someone has had to do that before.

If MRTG doesn’t do it, go to http://www.tucows.com and search their list of networking utilities.

Or you could just write a BATCH FILE, fanboy!! :smiley:

On Windows, PingPlotter (www.pingplotter.exe) does what you want and more, but it’s $15.

Or on unix, check out Nagios (www.nagios.org)

Or try this batch file:



@echo off

echo Wscript.Sleep 30000 > sleep.vbs

:start

ping 1.2.3.4 |find "TTL" >NUL
if errorlevel 1 echo error pinging 1.2.3.4

start /w wscript.exe sleep.vbs

goto start

Sorry about the sleep kludge. If you want it to email you on failure, check out the simple blat utility at http://www.interlog.com/~tcharron/blat.html
