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

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. And it does not work on localhost.
