Without that, adapter teaming is useless.<o:p></o:p> <![if !supportEmptyParas]> <![endif]><o:p></o:p> Another thing to try if you are really set on putting two NICs in your Nagios box would be to set up a source routing scheme of some sort. Just create static route statements on your box that point to some hosts out one interface, and point the rest out of the other interface. This can get very confusing very quickly though if you have many hosts on your network…I know on our network I would not relish trying to set a scheme like that up.<o:p></o:p> <![if !supportEmptyParas]> <![endif]><o:p></o:p> Currently I have Nagios on a SunFire 280R running Solaris 9 with only a single NIC and right now I have ~200 hosts and ~800 services being monitored and have not noticed any issue with the checks completing relatively quickly.<o:p></o:p> <![if !supportEmptyParas]> <![endif]><o:p></o:p> Neal Starr<o:p></o:p> Data Engineer, BSCS, CCNA<o:p></o:p> Cox Communications - Kansas<o:p></o:p> 316-260-7311<o:p></o:p> AIM: nealstarr1<o:p></o:p> <![if !supportEmptyParas]> <![endif]><o:p></o:p> -----Original Message----- From: Lambeth, Darwin [mailto:darwin.lambeth@starmountain.com] Sent: Monday, November 17, 2003 3:06 PM To: 'Jack Doyle'; nagios-users@lists.sourceforge.net Subject: RE: [Nagios-users] using multiple network cards <![if !supportEmptyParas]> <![endif]><o:p></o:p> You may want to consider adapter teaming.
