I usually use the default directory of /var/spool/snmptt. The SNMPTT tool also needs a spool directory to hold the incoming traps. # chown snmptt:snmptt /etc/snmp/snmptt.ini Next, copy the SNMPTT configuration file, snmptt.ini, to the /etc/snmp directory and snmpttconvertmib utilityĪlso needed are a user and group to run the SNMPTT daemon as. When a trap is received, this binary is executed by default and the trap sent to the snmptt daemon I specified the snmptthandler binary as the value of the traphandle option in the nf configuration file in the previous section. # chmod +x /usr/sbin/snmptt /usr/sbin/snmptthandler I recommend using the /usr/sbin directory First, copy the SNMPTT binaries to a suitable directory and mark them as executable.

The SNMPTT package has no installation script, so a number of manual installations steps need to take place.

This line shows how to download and unpack the SNMPTT tool:ĭownload snmptt_1.3.tgz which the latest version/stable release. You can get the SNMPTT tool from Sourceforge at. All traps will be sent to the snmptthandler script located in the /usr/sbin directory, the "disableAuthorization yes" tells to accept SNMP traps from all you can configure it to do authentication for detail refer to nf manual. Adding the default option tells the daemon that this is the default way to handle all incoming traps. The traphandle directive tells the snmptrapd daemon how to handle incoming traps and where to send them. Traphandle default /usr/sbin/snmptthandler This will make snmptrapd pass OIDs in numeric form and prevent SNMPTT from having to translate the symbolic name to numerical form." Make sure to remove the -c /etc/snmp/nf part, otherwise you will receive TRAP twice, as snmptrapd' is compiled with the default configuration file path being already set to '/etc/snmp/nf'.Īs quoted from SNMP Trap Translator documentation: "The -On is recommended. OPTIONS="-On -Lsd -p /var/run/snmptrapd.pid" #OPTIONS="-On -Lsd -c /etc/snmp/nf -p /var/run/snmptrapd.pid" The trap is then out-put to Nagios as a passive check result. If the trap matches, SNMPTT will see if the translated trap definition contains logic to output it to Nagios and execute that logic. The SNMPTT tool will then try to match the incoming trap against the collection of trap definitions that it has translated. When incoming traps are received from the snmptrapd daemon, they are passed to the SNMPTT tool.

Mib definition files for the equipment or software you need to monitor. For example, an authentication event or the change in status of an interface on a router may generate an SNMP trap that is sent to a management station of some sort, such as HP OpenView, CiscoWorks, Nagios.ĥ. The traps con-tain information about the status or an event on an SNMP-enabled device. SNMP traps are alerts and notifications generated by SNMP-enabled devices.
