SNMP Traps

[Beginner]

Hello dear friends,

I'm trying to get SNMP Traps to work, but am having alot of struggles with configuring so.


I am working on an Ubuntu machine and have followed this guide https://www.zabbix.org/wiki/Start_wi...raps_in_Zabbix
everything is basically the same expect for the package installations. And i didn't use the 2.2.1 version of the perl script but the 3.2.4 version, since i'm running zabbix on that version.

I did try everything and got it eventually to work, but as soon as i cheered, it got stuck again after rebooting. If i'm looking at my zabbix_server log there is an error saying:
Cannot stat file "tmp/zabbix_traps.tmp" no such file or directory.

When i manually create this file, i won't get the errors but the tmp file won't get filled with data of the received traps.

Also i've allowed port 161/udp and 162/udp with UFW and rebooted the machine.

Any ideas and help is appreciated
Bye

EDIT: Also these are the steps i did when trying to achieven snmp trapping

1. put zabbix trap receiver perl fil in /usr/bin and add execute permission in the perl file the trapping directory is /tmp/zabbix_traps.tmp
2. add following lines to /etc/snmp/snmptrapd.conf

authCommunity execute public
authCommunite execute ZabbixServer
perl do "/usr/bin/zabbix_trap_receiver.pl";

3. enable snmp trapping in zabbix_server.conf and define tmp file

StartSNMPTrapper=1
SNMPTrapperFile=/tmp/zabbix_traps.tmp

4. Add the MIB I want to use to /usr/share/snmp/mibs (DELL-SHADOW-MIB.txt) and define it in the /etc/snmp/snmp.conf with mibs +DELL-SHADOW-MIB
5. Reboot and enable services snmptt snmptrapd snmpd

Did you check the permissions on your "tmp/zabbix_traps.tmp" file? I had this issue as well. Maybe the user does not have rights to write to the tmp file.

I made sure that the user that is running my zabbix_server process (in my case, the group is zabbix and the user is zabbix), has ownership of the zabbix_traps.tmp file.

So I ran:
chown -R zabbix:zabbix tmp/zabbix_traps.tmp
