1. Firewall Settings

Open “/etc/sysconfig/iptables” with “vi” editor and add the following line to allow SNMP connections:

-A RH-Firewall-1-INPUT -m state --state NEW -m udp -p udp --dport 161 -j ACCEPT

Restart iptables service:

service iptables restart

2. Configurate SNMPD

Edit “/etc/snmp/snmpd.conf” and insert the following lines:

com2sec MY-TRUST-NET      public

group   notConfigGroup v1            MY-TRUST-NET

Note: Replace “” with your Subnet.

Now start the SNMP-Deamon with:
