I was sterolizing the error. Here is exactly what the error says. [1171638601] HOST NOTIFICATION: nagiosadmin;relay-1.lctn.org;DOWN;host-notify-by-email;CRITICAL - Host Unreachable (10.10.4.89) [1171638601] Warning: Attempting to execute the command "/usr/bin/printf "%b" "***** Nagios 2.7 *****\n\nNotification Type: PROBLEM\nHost: relay-1.lctn.org\nState: DOWN\nAddress: 10.10.4.89\nInfo: CRITICAL - Host Unreachable (10.10.4.89)\n\nDate/Time: Fri Feb 16 09:10:01 CST 2007\n" | -s "Host DOWN alert for relay-1.lctn.org!" <a class="moz-txt-link-abbreviated" href="mailto:admin@lctn.org">admin@lctn.org</a>" resulted in a return code of 127. Make sure the script or binary you are trying to execute actually exists... I do not have a misccommands.cfg, but I do have commands.cfg. using the "mail" command yields nothing, but as I mentioned, I do have sendmail installed. I can telnet to localhost on port 25. The reason I suspected it stops at "email", is that if I change the contact email, it shows up in the log file with the same error. </pre> </blockquote> If you "su" to the Nagios user, and just run "mail" - does it yield anything, or "command not found"? The error seems to be (as someone previously said) it's piping your notification text to " -s "Host DOWN..."" which isn't a valid command. You need to change your notification command to pipe the result to "mail -s ...." instead of " -s ..." You may also need to try "sendmail" (I don't use sendmail so I don't know if "mail" is part of it or not.) Andy. </body> </html>
