Trying to build an SNMP prototype

SUSE Linux:

yast -i nagios apache2
/etc/init.d/nagios start
/etc/init.d/apache2 start

Remember your login nagiosadmin:nagiosadmin and point your browser to http://127.0.0.1/nagios

/etc/init.d/snmptrapd
tail -f /var/log/net-snmpd.log
snmptrap -v 2c -c public localhost "" NET-SNMP-EXAMPLES-MIB::netSnmpExampleHeartbeatNotification netSnmpExampleHeartbeatRate i 42
No access configuration - dropping trap.

So it seems I have to

cat /etc/snmp/snmptrapd.conf
disableAuthorization yes
traphandle default /bin/snmppl
/etc/init.d/snmptrapd restart
cat /bin/snmppl
#!/bin/bash
date >>/tmp/dates

2014-05-06

Ok, the following command

snmptrap -v 2c -c public hostname "" NET-SNMP-EXAMPLES-MIB::netSnmpExampleHeartbeatNotification netSnmpExampleHeartbeatRate i 42

works and I can see on hostname

hostname:~ # tcpdump port 162
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes
12:09:02.418760 IP source.domain.45398 > hostname.domain.snmptrap:  V2Trap(77)  system.sysUpTime.0=60543145 S:1.1.4.1.0=[|snmp]

But I cannot receive it with netcAt.
