I'm using this tutorial to configure SNMP on my Windows server and Munin on my Linux server: http://munin-monitoring.org/wiki/Using_SNMP_plugins. 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 192.168.2.8:4949/tcp : 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...
