Hi, i'm debuging poller.php.
The error is on line 133:

exec_background($command_string, "$extra_args $first_host $last_host");

The command generated is:

/usr/bin/php -q /var/www/cacti/cmd.php 0 1

If i run this command from cacti user i get this error:

-sh-2.05b$ /usr/bin/php -q /var/www/cacti/cmd.php 0 1
->refusedsh: line 1: /perl: No such file or directory
sh: line 1: /perl: No such file or directory
sh: line 1: /perl: No such file or directory
sh: line 1: /perl: No such file or directory
sh: line 1: /perl: No such file or directory

But:
-sh-2.05b$ which perl
/usr/bin/perl


Can you help me?

Hi,

I've got the same problem.

- I just installed cacti with apt-get install cacti
- I use Ubuntu 6.06
- Everything works fine except the poller (Webinterface etc. are fine)

/usr/bin/php /usr/share/cacti/site/poller.php
sh: /php: No such file or directory
sh: /rrdtool: No such file or directory

The crontab exists within /etc/cron.d

cat /etc/cron.d/cacti
MAILTO=root
*/5 * * * * www-data /usr/share/cacti/site/poller.php >/dev/null 2>/var/log/cacti/poller-error.log

Someone has a hint for me what kind of problem it is?

Ah, I've found a mistake.
Within /etc/php5/cli/ safe_mode was defined. So it couldn't change to the given path i think...

But isn't it a security risk to disable safe_mode for the cli?

OK I've got teh same problem and have succefully fixt teh problem by disabling Safe Mode in php.ini - but this is pretty insecure no?

Again the error I'm getting is this:

sh: /rrdtool: No such file or directory

I was also getting the same error for /php but I fixed that by creating a .bash_profile and .bashrc for teh user 'catiuser' (something I'm also a little uncomfortable with - I usually use a /bin/nologin for users such as this...

Anyway the question I'm asking is - is there a a *safer* way to do this?

environment:

Madriva Linux 2006 rrdtool-1.2.15

Here is the quick fix I'm using:

Open poller.php and change the first line to:

Code: Select all

#!/path/to/php -d safe_mode=off -q

Then scroll down to around line 99 and find the current block of code:

Code: Select all

        /* Determine Command Name */
        if ($poller == "2") {
                $command_string = read_config_option("path_cactid");
                $extra_args = "";
                $method = "cactid";
                chdir(dirname(read_config_option("path_cactid")));
        }else if ($config["cacti_server_os"] == "unix") {
                $command_string = read_config_option("path_php_binary");
                $extra_args = "-q " . $config["base_path"] . "/cmd.php";
                $method = "cmd.php";
        }else{
                $command_string = read_config_option("path_php_binary");
                $extra_args = "-q " . strtolower($config["base_path"] . "/cmd.php");
                $method = "cmd.php";
        }

Change

Code: Select all

$extra_args = "-q " . $config["base_path"] . "/cmd.php";

and

$extra_args = "-q " . strtolower($config["base_path"] . "/cmd.php");

To

Code: Select all

$extra_args = "-d safe_mode=off -q " . $config["base_path"] . "/cmd.php";

and

$extra_args = "-d safe_mode=off -q " . strtolower($config["base_path"] . "/cmd.php");

Not the best solution, but you don't have to disable safe_mode for your whole site this way.
