Nagios Reply Email Acknowledgement Not Working

[hul1]

Hi I'm trying to set up my emails to receive the nagios XI ability to handle inbound email commands.
I tried to reply back to a Nagios problem email notification with a simple
"ack"
but it doesn't work but doesn't return a reply back error. I do see the following from /data/nagiosxi/var/cleaner.log
when I reply back to the mail server. This is a pop3 mail server using port 110 that I tested works for sending emails out.

Code: Select all

DIR: /usr/local/nagiosxi/nom/checkpoints/nagioscore
NUMFOUND: 10
KEEPING ALL GOOD CHECKPOINTS
DIR: /usr/local/nagiosxi/nom/checkpoints/nagioscore/errors
NUMFOUND: 10
KEEPING ALL ERROR CHECKPOINTS
DIR: /usr/local/nagiosxi/nom/checkpoints/nagiosxi
NUMFOUND: 10
KEEPING ALL SNAPSHOTS
----------------------------------
Running callbacks:
Error - Could not find a host object in the hash provided
Processed 1 incoming emails

Is the email an html email? Test by sending a plain 'ack' if possible. Usually the 'could not find a host object..." message is due to the message not parsing correctly. Try modifying /usr/local/nagiosxi/html/includes/components/xicore/xicore.inc.php so that the error check looks like below:

Code: Select all

// Verify that at least a hostname is present
                if (empty($obj->host)) {
                echo $email['body'];
                echo "Error - Could not find a host object in the hash provided\n";
                $error = true;
              }

This section starts on line 562. The echo $email['body']; is the new addition. Testing the function again should include the body of the email in the output.

Okay I reran it and looked for the message in the cleaner.log and got the following:

Code: Select all

KEEPING ALL SNAPSHOTS

Also I get an email back with the following:

Code: Select all

Could not submit command due to missing hash data. Did you reply with the full email?

It looks like the hash is wrapping, this should have been resolved in 5.6.6 of XI

Code: Select all

Fixed problem with reading multiple line hashes sent when an inbound email response is wrapped [TPS#14396] -JO

What version are you running?

[hul1]

Code: Select all

Nagios XI 5.6.5

Oh okay, I think we just need to upgrade Nagios and I can test it again. Thanks!
