How to configure Nagios to run plugin with sudo

[xtremax]

Hi Support,

I would like to know how to enable my Nagios XI to be able to run plugin using sudo. I have the following plugin that I used:

Code: Select all

#!/bin/sh
mount /mnt/backup
DESTINATION=`date +"$1"`

echo $DESTINATION
if [ -e $DESTINATION ]
then
        echo "OK - File exist."
       umount /mnt/backup
        exit 0
else
        echo "CRITICAL - File not found."
       umount /mnt/backup
        exit 2
fi

Since I am using mount and umount command, Nagios unable to run it and returning error. Please advise.

Thanks,

Rudy

Is this run on the local XI server, or on a remote host?
setuid on the script or edit the sudoers file with a new rule for user 'nagios'.
To setuid:

Code: Select all

chmod u+s <yourpluginfile>  

Or sudoers (add to /etc/sudoers):

Code: Select all

nagios  ALL=(ALL) NOPASSWD: /bin/mount

Hi abrist,

It's running on the local XI server. I have tried both of your suggestion, however I am getting the following error:

sudo: no tty present and no askpass program specified

Please advise.

Thanks,

Hi,

I have attached also the sudoers file for you to check.

Thanks,

The "no tty present" error indicates that you have the 'requiretty' setting in your sudoers file. In your case, it is probably in /etc/sudoers.d. Once this line is there, it does not matter what group you are in - sudo will require a tty whenever it is executed.

To get around this, you need to either remove (or comment out) the requiretty line in the configuration file, or add a line to exclude your user from the requiretty setting.

Hi abrist,

Thanks for your reply. However I am not able to find any configuration file in the folder /etc/sudoers.d.

Refer to my attached screenshot.

Please advise,

Just to verify, did you take a look in the /etc/sudoers file itself?

[xtremax]

Hi,

Yes, please refer to the sudoers file that i attached in my previous post and also to my attached screenshot.

What command did you use to edit your sudoers file? It must be edited by running

Code: Select all

visudo

and nothing else, no command line arguments.

Hi,

I am using visudo -f /etc/sudoers. I think it's the same thing right?

Thanks,

Rudy
