Guys,

I was wondering if one of you could provide some insight into this
issue I'm having with snmp. I'm trying to make my redhat linux server
a trap receiver to send out notifications for pages. Unfortunately
there's not much information on the web in the sense of a step-by-step
guide as far as installing and configuring snmp. In any case, I've
looked high and low and east and west and still have not been able to
make my snmp run. I've tried everything short of pulling my hair out.

At first I tried downloading and installing the latest file from
sourceforge but that didn't go well, so I later decided to install
SNMP from the RPM package on the redhat update page:
net-snmp-5.1.2-13.2.i386.rpm

I later installed all the dependencies the installation asked for as missing:

net-snmp-libs-5.1.2-13.2
elfutils-libelf-devel-0.97-5
elfutils-devel-0.97-5

The package installed all the necessary scripts on /etc/init.d:
snmpd
snmptrapd

When I run a remote snmpget or snmpwalk, it works perfect. The problem
is that I cannot process or receive traps. Any ideas as to what I
might be missing or what I have misconfigured?

Below you can find the configuration files as well as the debug
outputs for my system:
