<div>This is interesting. I don't run OSPF on my network, but my nagios servers are using Ethernet Bonding (2 NICs, 1 IP for failover). The very weird thing from my perspective is I only get the duplicate message on a specific switch (the mgmt IP on only 1 specific switch). </div> <div> </div> <div> Shlomo </div> <div>On 11/21/07, Roger Dierauer <<a href="mailto:thurgroup@gmail.com">thurgroup@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">Hi this phaenomen is also by me so... it seams, wenn you have ospf-network roules configured so the ping retourns on a second wire... its not a problem, but an interpretation issue from nagios kind regards roger <div>2007/11/21, Dennis Hünseler <<a onclick="return top.js.OpenExtLink(window,event,this)" href="mailto:dennis@huenseler.net" target="_blank">dennis@huenseler.net</a>>: <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0pt 0pt 0pt 0.8ex; BORDER-LEFT: rgb(204,204,204) 1px solid"> <div> Hello Stephen, this isn't a nagios error. You seem to have some Problems with your network. Try pinging the monitored host from your nagios host and there you should also see duplicate icmp-replys...

I am running nagios 1.2 on AIX and an monitoring both AIX and Windows client. I do a ping test using the check_ping command, but sometimes I get a problem with the ping which says " PING WARNING - DUPLICATES FOUND!", this then sends me the notification, then almost immediately I get the recovery notification. Can anybody explain why this happens and is there anything I can do to stop getting these false errors.
