However, snmptrapd and nagios are running on the same box and I'm not sure how to pass the traps to Nagios without using ncsa.

Hi,

    I've the same configuration but I can't get snmptrapd to work with 
nagios.
I've defined a volatile and passive service as described:

/etc/nagios/services.cfg:
#
#       Generic snmp-trap definition template
#
define service {
        name                            generic-snmp-trap
        register                        0
        service_description             SNMP Trap
        is_volatile                     1
        check_command                   check-host-alive
        active_checks_enabled           1
        passive_checks_enabled          1
        max_check_attempts              1
        normal_check_interval           1
        retry_check_interval            1
        check_period                    none
        notification_interval           31536000
        use                             generic-service
}

define service {
        host_name                       is1bfw01
        service_description             Test Trap
        use                             generic-snmp-trap
        register                        1
}
__END__

I've configure snmptrapd to use this attached script 
(handle-san-snmptrap) which send data to submit_check_result script,
like following:

/etc/snmp/snmptrapd.conf:
traphandle      .1.3.6.1.2.1.1.6.0                              
/usr/lib/nagios/plugins/eventhandlers/handle-san-snmptrap       1
__END__

If I'm executing this command test, I've got an alert on nagios:

# echo "is1bfw01
192.168.0.1" | /usr/lib/nagios/plugins/eventhandlers/handle-san-snmptrap 1

But when I'm sending a trap, using snmptrap on remote host, I've 
recevied this trap according to snmptrapd's log,
but no alert on nagios... Why ?

Dec  9 17:54:55 is1bin01 snmptrapd[22698]: 2004-12-09 17:54:55 
192.168.0.1(via 192.168.0.1) TRAP, SNMP v1, community public 
^I.1.3.6.1.4.1.8426.1.1.1 Enterprise Specific Trap (17) Uptime: 12 days, 
21:36:33.82 ^I.1.3.6.1.2.1.1.6.0 = STRING: Just here
