Is there a document that summarizes this configuration info? The signal to noise ration on the forums is pretty high.
Sometimes K.I.S.S. is the best way (edit your snmpd.conf file - not sure where it is on your server but try /etc/snmp/snmd.conf)
this one use v2c readonly to any thing that can get to the server over UDP 161 (you need to protect it with iptables or some type of firewall):
rocommunity public
sysLocation 1234 Main St, Hometown, CA 12345
sysContact MIS Department - (555) 555-5555
To protect a little bit more, you can add an IP after the community string
Here's a couple links that can help:
Easy And Simple Snmpd Conf Sample - Hummy
Manpage of SNMPD.CONF
Yeah, I'm not finding documentation either. I guess they expect we'll all just pay them for professional services to configure this stuff for us. Not.
