poller.php and perl file path

[juanito]

Hi,

I am running cacti under OpenBsd 3.7, Apache/1.3.29, php5 and mysql 4.0.23.

I am having some trouve with the poller.

When i try to launch poller.php, i tells me that it can't find the perl script, i know why, it's just that the path is not good.

The path to access to the script file shoud be /var/www/htdocs/cacti/scripts and no /htdocs/cacti. But i just can't figure out how to modify it.

If someone could help me it'll be nice

Thx in advance.

Um...

Did you move you cacti installation?

Either way, go into Utilities and run "Clear Poller Cache", which will rebuild those paths and display the results. It really doesn't clear it, but rebuilds it and shows the new results.

[juanito]

no i didn't move my cacti installation, i tried what you told me and as there was nothing changed, i uninstalled and reinstalled it completely (even sql database) and i have always the same problem

Looks like the web server is running in a chroot, which is causing you path issues.

[juanito]

yes it's running chrooted because it's the apache openbsd.

but i guess it's possible to do something, isn't it ?

[rony]

Create a link in the root of the file system so that the poller will work?

[juanito]

a link won't work, the aim of chrooting a server is that it can't acces to any file or folder outside the folder you consider as /.

I juste unchrooted apache by using -u in rc.conf

Thx for your help anyway

[rony]

I don't agree...

The chroot is to isolate a known process to a certain directory.

The Poller on the other hand is not running as the web server users under the web server, so it's not chrooted. So, if you did create a link on the root of the file system to the htdocs directory like the poller was looking for, you wouldn't decrease your security of the chrooted web server. Because, it's a link into the chroot, not out of the chroot.
