Its connectionless so as you send a request to it (or as it sends a trap out) it doesn't require a response. If you send an snmpwalk to it and it doesn't respond it could be because of network issues, a firewall, or very commonly an invalid community string. The default is public. Once you get the daemon up and running Try this command (change "public" to your community string if you changed it: snmpwalk -v2c -c public your.hostname.com That should send a bunch of stuff to std out. Once you get that info you can start getting information from the machines. I too use SNMP a lot for nagios, it works great. -Mike
