I have Nagios running on a local server, and I occasionally get some emails from it with the subject "*** SECURITY information for ***". The body of the message is just a few characters. I've done some searching in my Nagios logs and online, and I have no idea what these emails are or what they mean. The latest instance was last night. I had my local network torn apart for a few hours, and when I reconnected everything, I had about 40 of these emails waiting for me. The Nagios I'm using is from Ubuntu 9.10. I'm using only a very few HTTP, ssh, & ping monitors. Nothing complex at all. alex@artichoke:~$ cat /etc/issue Ubuntu 9.10 \n \l alex@artichoke:~$ dpkg --list | grep nagios ii nagios-images 0.4 Collection of images and icons for the nagio ii nagios-plugins 1.4.13+git200906171200-1ubuntu3 Plugins for the nagios network monitoring an ii nagios-plugins-basic 1.4.13+git200906171200-1ubuntu3 Plugins for the nagios network monitoring an ii nagios-plugins-standard 1.4.13+git200906171200-1ubuntu3 Plugins for the nagios network monitoring an ii nagios3 3.0.6-5ubuntu3 A host/service/network monitoring and manage ii nagios3-common 3.0.6-5ubuntu3 support files for nagios3 ii nagios3-doc 3.0.6-5ubuntu3 documentation for nagios3 I'll paste in 1 example email, including all the headers. If anyone has any idea what these mean, I'd be very grateful for some input. thanks, alex ======================================================== Return-Path: X-Original-To: root Delivered-To: alex@artichoke.dean Received: by artichoke.dean (Postfix) id 6FAC3212C7; Sun, 28 Nov 2010 21:29:59 -0600 (CST) Delivered-To: root@artichoke.dean Received: by artichoke.dean (Postfix, from userid 122) id 654D6212C9; Sun, 28 Nov 2010 21:29:59 -0600 (CST) To: root@artichoke.dean From: nagios@artichoke.dean Auto-Submitted: auto-generated Subject: *** SECURITY information for artichoke *** Message-Id: <20101129032959.654D6212C9@artichoke.dean> Date: Sun, 28 Nov 2010 21:29:59 -0600 (CST) artichoke : Nov 28 21:29:59 : nagios : ÇìP --------------------------------------------------- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
