    Looks interesting. Does anybody have tested this how it performs for a larger number of vhosts e.g. 100 - 20 performance and ram wise? The project is also marked as experimental at the moment.

    Implementing this in ISPConfig 3 should be easy and could be most likely done by simply changing the apache configuration template without programming.

    Would it be possible to add mpm-itk support in ISPConfig 2 ?

    mpm-itk sounds like a great way of dealing with PHP-security without sacrificing too much performance.

    I am running mpm-itk for 8 months now and I love it, to ad mpm-itk support to ISPCONFIG it is a matter of modifying apache templates to add:

    <IfModule mpm_itk_module>

    and for domains/subdomains.

    p.s. you have to install mpm-itk apache - apt-get install apache2-mpm-itk

    and that will remove your current apache

    Could these settings be applied during the install of ISPC3?
    E.g. the installer auto-detects which mpm you have installed?

    I could see adding this capability definitely, but in the case that a site has an issue with it you should be able to turn it off. This could be done safely by removing the user directives from the vhost. When mpm-itk doesn't see the directives in Debian it just defaults to www-data:www-data.
    I have used it with success and have been very happy with it for the experimental sites I have been testing but I haven't actually put it into production. The advantages you would have are phenomenal not to mention web applications that implement the DAV protocol.

    I noticed that you can't use shared applications, e.g phpMyAdmin. Am I wrong or is there a way around this?

    there is a way around this, I know I solved this some time ago, I think it was with phptmp dir - php_admin_value upload_tmp_dir

    actually for ispconfig you have to add:

    <IfModule mpm_itk_module>
    AssignUserId <tmpl_var name='system_user'> <tmpl_var name='system_group'>

    You'd likely also want to remove world read/write permissions from the files and remove world execute permissions from directories of the all the document roots for each vhost. I have mpm_itk working in a test environment as well, seems ok so far.

    I'm glad it's easy to add this feature. I use mpm-itk for about 70 virtual hosts running on my system. It has been fairly stable, and helps secure crappy php applications from each other for different users. I have been looking at various ISP packages for a while and am hoping to test out ISPconfig 3 now.

    I'll probably post a bunch of questions soon. :)

    How to change mpm-itk user from php?


    I have somewhat simple problem. i have x.com everyone is welcome, but when you login from a php form you will be able to see your files and folders.

    each users files will be on a separate /x/y/[user id] folder.

    So, on my x.com vhost directive i need to assign guest user at first then when user logs in i have to change the mpm-itk user so that user can work with his files.

    Do you know how to change this user dynamically? and i have thousands of users and each login should change user to corresponding unix-user.

    mpm-itk only works on a per <VirtualHost> directive in the apache config.

    in each <VirtualHost> you can use AssignUserID.

    See the itk docs: http://mpm-itk.sesse.net/
