i downloaded Nagios Checker and i was told in this web http://theanswersquad.com/?p=131 that i have to add the add-ons for Nagios Checker. But when i opened the firefox browser, i went to Tools > Add-Ons.. under the Add-Ons i did not see the Nagios Checker, by right it should appear..how come?

I'm not sure I follow completely. Did you install the extension? The first tab in the add-ons dialog is for searching and installing them. When I typed "nagios" in the search tab it popped up right away. Then it's simply a click of the "add to firefox" button to run the installer for it.

The other way to manually install an extension is to download the .xpi file to your hard disk, then use Firefox's "open file" dialog to access it. If it's a valid file, it should then run the install dialog.

Hi David,

Thank you. I've managed to install the extension already. Thank you once again =)

BTW, the 'hard disk' you mentioned is those C:/ drive, D:/ drive etc? (:

Thanks.

By hard disk, I mean any user storage space available to you, usually somewhere in your home directory.

And drive letters are a windows thing. Linux doesn't use them. Physical hard disks can be mounted anywhere on the file tree. At the very least you'll have /, your root directory, on one physical partition. If you have multiple partitions or drives, then you may have various sub-directories, such as /home, actually existing on them instead.

The "mount" command without any options will show you all the drives your system is currently using and their locations in the file tree.

Oh i see. Thank you.

By the way have you use Nagios Checker before? There's something wrong with it. Initially when i first set it everything was working. but after i restarted my computer (i installed Nagios Checker on ubuntu 9.10 in a VMWare machine), it gave me "1 error". I don't know whats wrong.

ADD ON:

Never mind, i solved it.

Thanks again
