I have a CentOS machine that has selinux in enforcing/targeted mode and is monitored with snmp checks by nagios successfully. The SE boolean value for snmpd_disable_trans is off on my machine and I can still query snmp. I would recommend the following: . check the firewall/iptables rules for udp port 161 . enable logging in iptables to see if the firewall is dropping packets (requires more work) . check the source and string under the com2sec definition in snmpd.conf . check the view definition in snmpd.conf, defaults are a bit restrictive . try using the setroubleshoot browser to see if any snmpd related warnings pop up. These warnings can include a section called Allowing Access.
