SNMPD on linux

Hi,

I’m starting to use The Dude for SNMP monitoring here at work and it’s wonderful for all network equipment and Windows boxes.

… but I’m having real problems with getting SNMP working reliably with some Linux boxes.
(I’ve had no problems with our Red-hat boxes)
The boxes in question are Ubuntu based. (8.10)

Basically, the SNMP services go up and down every 5/10 minutes. There doesn’t appear to be a pattern to it although it seems to be down for 5 minutes every 15 mins (approx).

When I reprobe from the polling menu the items stay on “timeout” for a while before going back to OK.

While writing this; the interface that the system is using to communicating on has dissappeared from the SNMP/Interfaces tab and even though I know it’s still up (I’m connected to the server through it) it will not come back with a refresh.

I should be able to stop the SNMP service and restart it and all should be fine for about 5/10 minutes.

Has anyone else seen this problem? Have I misconfigured somthing on the Linux box?

Just ask if you need any more info/screen shots etc

Thanks,

Aikidoka

Make sure you get the latest net-snmp for ubutu.
net-snmp has some odd bugs in it.

I have a Suse 10 server. snmp refused to report CPU%, but after a bit of searching on googled, this turned out to be a net-snmp issue.
I upgraded net-snmp and the problem went away.

Thank you, I will try to look to see if there is a newer version available to download.

Thanks again,
