I'm using this tutorial to configure SNMP on my Windows server and Munin on my Linux server: SNMP on the Windows server works fine, I have checked that with the snmpwalk tool on Linux.

When Munin runs an update I got the following error:

2011/10/03 15:20:22 Failed to connect to node : Connection timed out

This is 'correct' since SNMP is UDP and runs on port 161. Did I miss something in the tutorial? I have the feeling the SNMP configurator of Munin is not setting the host to SNMP or something...

Munin is attempting to contact a munin-node. You haven't configured it correctly. What's your munin.conf, and how is your node setup so far? – Kvisle Oct 31 '11 at 11:08
Thanks for your comment, I have already fixed this issue. Something was wrong in my configuration indeed. – Marthijn Oct 31 '11 at 13:07
