Just install and configure SNMP.

The specific opinions are as follows:

First, you need to install SNMP. Please refer to the SNMP installation instructions for LINUX system. Generally speaking, SNMP services have been automatically installed in Linux. The following command can detect whether the SNMP service is installed and the installed file package.

Then remove the following # sign, # viewmib2included.iso.org.dod.internet.mgmt.mib-2fc. Then change the AccessNotConfigGroup ""any noauthexactsystemviewnone "to: AccessNotConfigGroup" "any noauthexactMIB 2None or: AccessNotConfigGroup" "any noauthexactallNone.

Then generally start and stop SNMP: servicesnmpppdstart | stop | restart command. Or: #/etc/rc.d/init.d/snmpdrestart.

Finally, you can set up a firewall. If Linux starts the firewall, please open UDP port 16 1. Ensure that the iptables firewall of Linux has opened the udp 16 1 port to access the SUM monitoring server. You can modify iptables rules by editing the /etc/sysconfig/iptables file.
