SNMP on various systems

CentOS Server

To enable SNMP on a CentOS server, install the net-snmp-utils and net-snmp packages with yum (yum install net-snmp-utils net-snmp -y as root or with sudo) and edit the configuration file at /etc/snmp/snmpd.conf to suit your needs.

Windows Server (Via AD DS)

To enable SNMP on a Windows server managed by AD DS, install the SNMP feature through Server Manager, and (if needed) install the associated Remote Administration Feature (i.e. SNMP-Tools) on the appropriate server. If needed, enable remote management.

  • Note: To install the Remote Administration Feature locally as a Domain Admin, I had to run Server Manager as Administrator

On the server you want to manage, allow Remote Management through the firewall with PowerShell: Set-NetFirewallRule -DisplayGroup "Remote Event Log Management" -Enabled True

pfSense Firewall/Router

To enable SNMP on a pfSense firewall/router, go to the web admin interface, and, from the Services drop-down, select SNMP. Fill in the fields with the appropriate values, save, and click the restart service button at the top of the page
