Problem with snmptrap

[Eduardo S. C. <eds...@gm...>]

Hello.
I want to receive traps with snmptrapd, but It doesn't work.
This demon dont print anything to standar out neither to syslog when I
send the trap whit sendtrap:
snmptrap -v 1 -c zweicom_notav 192.168.1.168:162
.1.3.6.1.4.1.19408.2.1 localhost 6 303 .1.3.6.1.4.1.19408.1.1.2.0

I start with:
condor:~ # snmptrapd -m all -f -Lo -C -c /etc/snmp/snmpd.conf
NET-SNMP version 5.4

I know the traps arrive because I try strace:
condor:~ # strace snmptrapd -m all -f -Lo -C -c /etc/snmp/snmpd.conf
.....

recvmsg(7, {msg_name(16)={sa_family=AF_INET, sin_port=htons(1079),
sin_addr=inet_addr("192.168.1.168")},
