Problem with poller.php under Solaris

[Einstein]

Hi guys,
I've got a problem with cacti under Solaris 10 with Sun Webserver 7U2 and the php-plugin

If I run the poller.php manually or with cron I get everytime the same result.

on the one hand this

Code: Select all

root@t1000 /opt/webdocs/cacti # /opt/sunwebserver7/plugins/php/bin/php poller.php
X-Powered-By: PHP/5.2.0, Sun add-on 1.0
Content-type: text/html

and then a black screen

on the other hand there appear these line

Code: Select all

root@t1000 /opt/webdocs/cacti # /opt/sunwebserver7/plugins/php/bin/php poller.php  --force
sh: /usr/local/php/bin/test: nicht gefunden
sh: /usr/local/php/bin/rrdtool: nicht gefunden
X-Powered-By: PHP/5.2.0, Sun add-on 1.0
Content-type: text/html

06/09/2008 05:24:41 PM - POLLER: Poller[0] Maximum runtime of 298 seconds exceeded. Exiting.

<br />
<b>Warning</b>:  pclose(): 55 is not a valid stream resource in <b>/opt/webdocs/cacti/lib/rrd.php</b> on line <b>57</b><br />

"nicht gefunden" = not found

I hope anybody got an idea.

From the error, it would seem the poller cannot find rrdtool. You have rrdtool installed don't you?

[Einstein]

yes i've installed rrdtool-1.2.19 from sunfreeware.com and the actual mysql database from mysql.org

php version: 5.2.0
mysql version: 5.0.51a

But is it along this path:

sh: /usr/local/php/bin/rrdtool: nicht gefunden

it's telling you that it cannot find the tool in the path given.

after i have set a symbolic link to my rrdtool there will only be the problem with

Code: Select all

sh: /usr/local/php/bin/test: nicht gefunden 

and i dont know what 'test' is

One thing to check is php.ini settings, if you keep your binaries outside of you open_basedir or safe_mode_exec_dir:

safe_mode = Off
safe_mode_exec_dir =
open_basedir =

This naturally poses a serious security threat. However, I have created a dedicated vhost instaed for cacti and set these within vhost definition:

<VirtualHost _default_:8080>
Port 8080
DocumentRoot "/u/httpd/htdocs1"
...
<IfModule mod_php4.c>
php_admin_flag safe_mode off
php_admin_value safe_mode_exec_dir none
php_admin_value open_basedir none
</IfModule>
</VirtualHost>

Thats's because I'm running cacti for home use, not corporate or something. Or better so, create a cacti vhost and set your open_basedir path to cacti root, put needed executables in safe_mode_exec_dir and check whether the owner is the same as the apache user, to satisfy safe_mode on setting. All withing httpd.conf vhost section, to create specific php local settings, overriding php.ini globals on a vhost basis. Note that running poller from a crontab, will use defaults in php.ini, so to be able to use alternate php.ini, you should set PHPRC system variable to point to your modified php.ini before running the polling script or loosen-up restrictions in default php.ini and strenghtem them afterwards within your httpd.conf for each vhost defined. However, I'm not yet sure, what other security implications this approach may have.

Just a suggestion, but that was a real problem that I've stumbled upon.
