What SNMP manager tool would you recommend?
 

hello

I'm trying to learn about SNMP but I don't know which SNMP management tool to install.Any suggestions?
As an agent Im thinking of using snmpd daemon

And last but not least...is learning SNMP a must if one wants to master network security?

thank you

For Windows or Linux?

net-snmp.
in the past it was known as ucd-snmp.

If you're looking for an SNMP MANAGEMENT console, though, you're going to want to look in the direction of something similar to OpenNMS, which is an open source tomcat-based SNMP management platform.
