Here is our NRPE documentation including installation and configuration:

http://nagios.sourceforge.net/docs/nrpe/NRPE.pdf

And here is NCPA, an agent that will work on Windows:

Hi all,

Thanks for the links. Pls am having with issues with my nagios user . I can't login with the nagios user on my ubuntu so as to modify my configurations, but I can log on with the root user and root user does not have access to all this file. Pls I will be glad to hear from.

The root user should have access to all files on a system. What files are you having trouble accessing?

Hi tmcdonald,

I don't have access to usr/local/nagios/etc/objects

I dont have access to the files under objects i.e command.cfg, window.cfg. When i do ls -lart on the file, i could see that is only nagios user that has access to the file, i try to switch to the user but the password is not working.

Please what can i do. I awaiting your swift response.



Best Regards.

Unless someone specifically changed permissions to something very unlikely, root always has access to all files on a Unix filesystem.

You don't need to switch to the nagios user to be able to edit the files, you can do so as root. The nagios user will need access to the files after you're done modifying them, which can be done with the command:

Code: Select all

chown -R nagios /usr/local/nagios

Hi tmcdonald,

i tried to open the file with text editor and am unable to save the file, its keep saying i dont have permission to the file.

Am using a root user. I try to use the command you gave me , but its keeping saying operational not permitted.


Am trying to use vi editor now. But i would appreciate if you can assist me.


Many thanks

For fun, please type the following command, exactly as written (copy and paste it), and then paste the results back to your reply in this forum:

Code: Select all

find /usr/local/nagios/etc -ls

Hi tmcdonald,

kindly find the attached output.

Thank you. It was me (eloyd) that asked for that, not tmcdonald, by the way.

This tells me that your protections are set properly on the files, so there should be no reason why root cannot edit the files you need to change. Make sure that you are logged in as root and not yourself or the nagios user before editing. You can find out what user you are logged in as by typing "id" (short for identification) without the quotes. You should see something like this:

Code: Select all

# id
uid=0(root) gid=0(root) groups=0(root)

If you do not see the first part that says uid=0(root) then you are not the root user. You may need to type "sudo -i" first to become root.
