FreeBSD 6.x versions have in ports a service for snmp monitoring: net-snmp, located in /usr/ports/net-mgmt/net-snmp, and also available as package. Here are few tips for setting up and debug a snmp service: Tip 1. Configure your net-snmp service ---------------------------------------------------- After you've installed net-snmp package you wll find an example config file here: /usr/local/share/snmp/snmpd.conf.example In order to setup net-snmp service, rename snmpd.conf.example file to snmpd.conf and copy it to: /usr/local/etc/snmp/snmpd.conf Also you could generate a snmpd.conf with a Perl script: # snmpconf -g basic_setup Tip 2. Verify your net-snmp service ---------------------------------------------- Before checking functionality of snmp to make sure that is started, you can do a ps: # ps awux | grep snmpd If the process is started, to make sure it works we can scan from outside to see if is port 161 is open: # nmap 10.0.0.1 sU -p 161 After modifying snmpd.conf and starting the service, you can test functionalty of snmp service with snmpwalk: # /usr/local/bin/snmpwalk -v 2c -c public 127.0.0.1 Tip 3. Accessing a net-snmp information from command line --------------------------------------------------------------------------------- To get info about a specific snmp parameter of snmp service: # /usr/local/bin/snmpget -v 2c -c private 127.0.0.1 system.sysUpTime.0 |
