snmp
Most of it is pretty straight forward. For those who are unfamiliar with snmp, here's what you need to add to /etc/snmp/snmpd.conf# sample configuration for SNMP V3 # create an SNMP V3 user with an authpassphrase and a privacy passphrase ## username authProto authpassphrase privProto privpassphrase ## -------- --------- -------------- --------- -------------- createUser someuser MD5 myauthpass DES myprivpass # Second, map the security name into a group name: ## groupName securityModel securityName ## --------- ------------- ------------ group groupv3 usm someuser # Third, create a view for us to let the group have rights to: ## incl/excl subtree mask ## --------- ------- ---- view all included .iso 80 # Fourth, create the access for that group without context ## context sec.model sec.level prefix read write notif ## ------- --------- --------- ------ ---- ----- ----- access groupv3 "" any auth exact all all all
Then test it with
shell>snmpwalk -v 3 -a MD5 -A myauthpass -x DES -X myprivpass -u someuser -l authpriv localhost interface
