Can anyone kindly help me on this issue?
I'm using Core13 for Zabbix 1.8.2, and trying snmptrap works on Zabbix.
However, every time snmptrapd gets a snmp notification, it aborts. With debug
mode, it reports a buffer overflow detected. I've tried another Fedora core 13
and a core 12, with net-snmp 5.5. On these three systems, snmptrapd behaves the
same.
Here is my snmptrapd.conf,
disableAuthorization yes
traphandle default mail -s trap some...@somewhere.com
I triggered snmptrapd with,
snmptrap -Ci -v 2c -c public localhost "" "1.3.6.1.4.1.8837.4.1.2.1.2.1.6.4"
1.3.6.1.4.1.8837.4.1.2.1.2.1.6.4 int 500
Same result I got with my firewall snmp traps. Some other different scripts
replaced in traphandle default, got the same.
A small portion of debug info listed,
