Simple Network Management Protocol (SNMP) is an “Internet-standard protocol for managing devices on IP networks”.

SNMPv3 moves away from the community string idea from older version, and into a username & password combo. The installation and setup is actually pretty straight forward. Here’s what you need to do:

Yum will pick up the dependencies you need. Now as root, run (make sure snmpd is stopped first)

You’ll get the following output…

Before testing make sure that UDP 161 is permitted through iptables, and restart snmpd

You should test your installation from another workstation using the SNMPWALK command.

If the command fails, you will see an error. If you’re successful, your screen will fill up with a lot of SNMP messages.

Enjoy!

    I think it’s supposed to be:

    iptables -A INPUT -p udp –dport 161 -j ACCEPT

    (instead of -p tcp)
