/etc/init.d/snmptrapd not starting daemon

[enrique-t]

Hi. Maybe you can help me.

I am trying to set up traps for zabbix. By now i am stuck in making snmptrapd work

If i start it manually it works, and i see traps on log file:
/usr/sbin/snmptrapd -On -Lf /var/log/snmptrapd.log
root@zabbix-test:/etc/init.d# ps -elf | grep snmptrapd
1 S root 6504 1 0 80 0 - 17045 - 16:17 ? 00:00:00 /usr/sbin/snmptrapd -On -Lf /var/log/snmptrapd.log

If i start it using init.d script:

/etc/init.d/snmptrapd start
[ ok ] Starting snmptrapd (via systemctl): snmptrapd.service.

root@zabbix-test:/etc/init.d# ps -elf | grep snmptrapd
0 S root 6551 1332 0 80 0 - 3182 - 16:19 pts/0 00:00:00 grep snmptrapd
(NO PROCESS SNMPTRAPD RUNNING AFTER THAT)

root@zabbix-test:/etc/init.d# service snmptrapd start
root@zabbix-test:/etc/init.d# service snmptrapd status
● snmptrapd.service - LSB: SNMP Trap daemon

Oct 25 12:52:43 zabbix-test snmptrapd[5800]: Starting SNMP trap services::


I guess the key in in knowing why state is active (exited). Maybe some kind of problem in my script, which i paste bellow:

Any help or hint of how to troubleshoot this is more than welcome and thanks

Found problem

The variables configured in /etc/default/snmptrapd.conf takes precedence over the defined ones in /etc/init.d/snmptrapd. Its commented mentioning that but probably because of age decadence i was missing to read it.
