Okay, I basically have a script that uses passthru when people login with FTP so it can connect users from multiple interfaces.
Thing is, it uses the default php.ini file so, to get this script to work I have to enable passthru in the default php.ini file, affecting all users with an account. I am currently running SuExec and can change the php.ini file each user uses from httpd.conf. But as far as I am aware the FTP user isn't in httpd.conf.
What user does FTP run under and how can I use a custom php.ini file just for the FTP daemon. Also, as a side note, what are the effects of passthru and can it be used for malicious intent if wanted?
