the first test just checks to see if someone gives a dhcp lease. the second will fail unless that specific server gives a dhcp lease.
it's possible you have a dhcp server trying to give a 0 second lease or the plugin may have a bug, are you sure it said 1 DHCPOFFER and max lease time 0 seconds? try -vvv to see who is giving you these leases. You generally only need 1 dhcp server per subnet or if you have more you should make sure they have non-overlapping address pools. I actually made a wrapper script to this to actually warn me of rogue dhcp servers on the network after an incident with some clumsy person installing vmware with it's dhcp and sending a laptop off to the wrong subnet... so you might want to check why the second attempt says you had 3 DHCPOFFERS. I would investigate if that was the case on my network... -h Hari Sekhon abid dar wrote: > Having a weird situation.. > > /usr/local/nagios/libexec/check_dhcp > DHCP ok: Received 1 DHCPOFFER(s), max lease time = 0 sec. > > /usr/local/nagios/libexec/check_dhcp -s xx.xxx.xxx.xxx (our dhcp server) > DHCP problem: Received 3 DHCPOFFER(s), 0 of 1 requested servers responded, > max lease time = 284400 sec. > > why is it getting a DHCP okay when I do flat check_dhcp but when I specify I > dont get a valid response. > > Also, the verbose option does not give any more information.. but thats not > really important.. > > Any thoughts? > > > > > > > > __________________________________________________ > Do You Yahoo!? > Tired of spam?
