error when configuring traps

[Xyue]

Hi guys,

I am configuring traps by following below link.

https://www.zabbix.org/wiki/Start_with_SNMP_traps_in_Zabbix#Install_Zabbix_from_packages

when i try to run below command, i have error message as shown below.
Command
snmptrap -v 1 -c public 127.0.0.1 '.1.3.6.1.6.3.1.1.5.4' '0.0.0.0' 6 33 '55' .1.3.6.1.6.3.1.1.5.4 s "eth0"

Error Message
No log handling enabled - turning on stderr logging
Cannot rename /var/lib/net-snmp/snmpapp.conf to /var/lib/net-snmp/snmpapp.0.conf
Cannot unlink /var/lib/net-snmp/snmpapp.conf
read_config_store open failure on /var/lib/net-snmp/snmpapp.conf
read_config_store open failure on /var/lib/net-snmp/snmpapp.conf
read_config_store open failure on /var/lib/net-snmp/snmpapp.conf

I check the location /var/lib/net-snmp/ and notice there is no snmpapp.conf.
Does anyone encounter this before ? If yes, kindly advise what cause this message.

Thank you very much.

Check write permissions on /var/lib/net-snmp.

Hi,

Thanks, just check every file that are related and notice most of them are belong to other owner and permission was not set. Has change the owner and permission and works after that.

Thank you very much for your help

Hi,

I have some problem and required your help again.

Now the snmptraps works and it was able to save the file to the log file.

/etc/zabbix/zabbix_server.conf:
#SNMP Trapper
StartSNMPTrapper=1
SNMPTrapperFile=/var/log/zabbix/zabbin_traps.log

/etc/snmp/snmptrapd.conf
authCommunity log,execute zabbix
perl do "/usr/bin/zabbix_trap_receiver.pl";

I would like to show the traps on the web interface and I found below document to let snmpd work with snmptt

https://www.zabbix.com/documentation/2.4/manual/config/items/itemtypes/snmptrap

https://www.zabbix.org/wiki/ConfigureSnmptrapsCentos6_RHEL6

After i install snmptt, i was unable to find the snmptt.conf.
I'm not sure why the snmptt.conf is not in my directory

Can anyone advise me how to deal with this problem ?
Thank you very much.
