running shell_exec commands as root

[Lawrence Krubner]

I've a PHP script that is run as a cron job. It contains this line:

$stringListingAllProcesses = shell_exec("lsof | grep vsftpd");
The lsof command returns almost nothing unless you are the root user.
Can anyone think of a way I can use su or sudo or something else to get
this script to run as root?

(And yes, I'm aware that it is dangerous to allow a PHP script to run as
root, but it is in an otherwise secure environment, far removed from the
web.)

Hi,

The easiest way is to make a cronjob for root.
Just go root and crontab it.

If you have no rootaccess, you cannot run as root of course....

That is what I tried first. I logged in as root and did "crontab -e".
But the script doesn't seem to run as root. The lsof in the script
seems to run as... I don't know who. It returns no data, which would
make sense for a non-root user.

Hi,

Roor user should be able to run that command just fine.
Are you sure you simply don't have a process named 'vsftpd'?
What does this produce:
$stringListingAllProcesses = shell_exec("lsof");

Also nothing???
