Network Monitoring (SNMP) - richnadeau/Tech-Journal-SYS265 GitHub Wiki

Network Monitoring allows us to monitor different servers on one server.

First, you will need to enable and setup snmp on the firewall. On the nmon server (centos), you will need to install nmon services with #sudo yum install net-snmp-utils.

Then to install snmp server on web01, you install by #sudo yum install net-snmp-utils net-snmp. On the firewall for web01 you will need to allow snmp service and reload firewall.

Installing snmp service on ad01-rich is easy as you can just go to server manager on mgmt01 to install the service through that. Same goes for installing snmp tools for mgmt01 you can just do it through server manager.

The snmp service security will need to be fixed by adding the community string to it as well as nmon01 to be able to send snmp packets to and from ad01. When edited, apply and restart service.

Command to do a network monitor: #snmpwalk -Os -c <Comm_String> -v2c <server_name> system

Definitely want to know more about how to do this protocol securely (that's what the project is for). Are there any more protocols that work similarly to snmp or is this the only protocol like it? If so is that protocol more or less secure than snmp?
