I have recently installed v4b2. Apart from some issues installing and configuring, the main issue I have encountered is that I can no longer connect with SNMP to my Windows 7 box.
Here's the thing.
It shows 'down' although I can connect with SNMP from another network monitoring system (PRTG). The only agents are 'default' and 'server' - I have not set up any agents. However when I do an SMNPwalk I have a different two choices for agent - 'default' and 'local'. Trying 'default' gets me a timeout. But trying 'local' does a successful walk. But 'local' isn't one of my choices from the 'general settings' tab, of course. (I don't even know why it's there as an option when doing an SMNPwalk.)
This seems like a bug to me. The SNMP monitoring is working ok on the Win 2003 server boxes and the Ubuntu box, so I suspect that it's a bug related to Windows 7, maybe?
