Ok, I noticed from your screenshot that your tcpdump is listening on eth9, is that the proper one?

Have you checked on the destination server at all?

yes, is correct. If I run snmptrap from command line with nagios user trap is sent even though there are errors about snmpapp.conf.

Code: Select all

I ran your test and did not get those errors.

What are the permissions on the file?

Code: Select all

ls -al /var/lib/net-snmp/snmpapp.conf

Here are the permissions.

Code: Select all

[root@az84mon11v ~]# ls -al /var/lib/net-snmp/snmpapp.conf
-rw------- 1 root root 675 Jul 17 12:22 /var/lib/net-snmp/snmpapp.conf

I get the same errors when running the snmptrap command as the nagios user and mine works properly. Let me dig into the code to see if we have any additional logging we can look at.

Post the full output of this command:

Code: Select all

echo "select value from xi_options where name = 'snmptrapsender_component_options';" | psql nagiosxi nagiosxi

You may want to try downloading the snmptrapsender component again:

https://assets.nagios.com/downloads/nag ... sender.zip

Then go to Admin > Manage Components and re-upload the component so that it re-installs and try it again.
