That's basic script programming.

man bash man ping man mail

#! /bin/sh

H='10.0.0.2' ping -q -c 1 $H &> /dev/null || echo "Host $H died" | mail root -s "Host $H died"

RTFM? Thanks. I knew there was a tool somewhere on the list.

Two lines more, and make H a space-separated list of host/ip#; make a cron job that calls the script, and I think you're done. ;) HH="10.0.0.2 10.0.0.3" for H in $HH; do ping ..... done Cheers, Leen

Good point. What about the "mon" tool? Anybody have any opinions on this? Carl William Spitzer IV wrote on 09/07/2004 01:00:08 PM: ping

That's file if you want root notified. What about mailing a user perhaps at your online or squirl mail account which you can check while on the road?

Exactly what did you not understand from mail's manpage?

Manpage?? What manpage? What's manpage? What are they for? Why would I want one? What would I see there? Would you read it for me and tell me what it says?

Check out BigBrother it should fit the bill.

Or Nagios. No licensing issues with Nagios like there are with BB either. I use it heavily myself. http://www.nagios.org/ -- Jarod C. Wilson, RHCE jcw@wilsonet.com

Let's say my email server crashed and Big Brother/Sister is watching it. How would I be alerted over email? Is there another method to being alerted? -- Tom Nielsen Neuro Logic Systems, Inc. 1.805.389.5435 x18 www.neuro-logic.com

Dude: send your alert email to your cell phone. No one would send alerts to the same server that is down. Lemmie see, Where did I put that Clue Bat... ;-) -- _____________________________________ John Andersen
