R e n d r a g

I spent an hour this afternoon cleaning up our OpManager install, making sure the new servers in the NZ office are monitored correctly.

And then I realised that we don’t have SNMP enabled on the XenServer hosts over there.

Turns out it’s not too hard though:

Edit /etc/sysconfig/iptables

Add in amongst the other allows:

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

# service iptables restart

Edit /etc/snmp/snmpd.conf (aka change public to something more secure)

# service snmpd restart
# chkconfig snmpd on

Yup, that was easy 🙂
