    Hi Guys
    I have moved up to Debian Etch from sarge, and the
    "apt-get install libapache2-mod-security" command doesn't install it now.
    My apt source.list contains the same links as in the perfect set up for Debain Etch by falko (thanks falko)

    Is there any issues with installing mod_security on Debian Etch, if not which is the best way to go about it?

    Maybe the name of the package has changed a bit. Do you see the package when you run
    apt-cache search apache

    Hi Falko

    hope you are keeping well

    I have run
    apt-cache search apache, and it doen't seem to be mentioned at all.

    Any other sugestions on how to proceed.

    thanks again

    same trouble here :-( tried apt-cache search apache | grep secur and that did not yield any results that resembled what we were looking for...

    I can't find it either, which leads me to the assumption that it is included in the normal Apache package. What's the output of
    ls -l /etc/apache2/mods-available

    Hi everyone
    Just wondered if anyone had any further help or advice on getting mod_security installed and working on Debian etch.

    I have tried downloading the latest release from

    and followed these install instructions

    but after making the additions to the apache2.conf as described and then restarting apache, it comes up with a failed message saying module not found.

    I have done a "locate mod_security" and there is a entry now in

    this is all that was located.

    I guess this install is not quite right for Debian Etch? any ideas

    Any help on how to install it would be very much appreciated.

    those links seem good, I'll give it a try these days and see if it works for me or if I come up with another idea...

    What exactly did you add? What's the output of
    apache2 -V

    tsmaudio New Member

    Hi falko

    I just added my mod_security configuration to the end of the apache2.conf
    with this line at the beginning as explained in the install instructions, "LoadModule security2_module modules/"

    LoadModule security2_module modules/

    <IfModule mod_security.c>
    #Turn the filtering engine On or Off
    SecFilterEngine On
    # Change Server: string
    SecServerSignature " "



    The output of apache2 -V is as follows:

    Server version: Apache/2.2.3
    Server built: Mar 27 2007 14:57:24
    Server's Module Magic Number: 20051115:3

    Please move this line to where the other LoadModule lines are.
    Is located in the same directory as the other modules? What's the output of

    another maybe unrelated question, but I thought it might fit in her:

    after the upgrade there are a lot of new modules in the /etc/apache2/mods-enabled folder,.... is there a psot somewher explaining what these new moduels do and whic ones we coudl disable safely?

    i.e. I have these:

    I didn't activate all those auth* stuff, I activated and use: cache, fastcgi + fcgid (as I never found out how to use only one of them :) mem_cache + suexec... unsure about all the others except a few obvious ones like php4 and ssl - before the upgrade I was also using mod_security and dos_evasive which did not work after the upgrade so I took out their .load files until I fix the issue...

    I think I have to try mod_security myself on Etch before I can give any help. Seems a lot of things have changed...

    I ran into this problem a while ago when upgrading. It seems the mod security package has been removed from debian due to some license issue. I found an unofficial package here: which installed successfully for me.

    Just add this line to /etc/apt/sources.list:

    deb ./

    then install with apt (note there is a different package for apache 2).

    There might be a better way to do this, but it fixed my issue - hopefully it helps someone else.

    any more news on this? One client was dead impressed with mod_security but I can't for the life of me get it working on debian etch. Does anyone have a link to a detailed howto, or has the patience to write a step-by-step howto on installing mod_security with apache2 on debian etch? I have the feeling the author of such a howto will make friends for life!
    And yes, I have googled.
    Thanx in advance

    Oh for crying out loud, I'm always doing this! Posting a question and finding the answer ten minutes later! I didn't read the last post properly - go here:-

    and download. The install asked for mod-security-common but synaptic dealt with that. Piece of cake in the end! Weeks of frustration and one happy client! Take note - read other posts carefully!!!

    I have tried to install mod _security using the link provided by "eze".
    It installed without any problems, but when I am testing it using the methods described here

    It doesn't seem to be working or doing anything at all.
    I had this in the error.log

    [error] ModSecurity: ModSecurity requires mod_unique_id to be installed.

    So I looked to see if it was on the system and it seemed to be, so I just enabled it using

    a2enmod unique_id

    and restarted apache, but it made no difference, it was still doing nothing.

    I am wondering if anyone else has tested it to see if this install works?

    Any help would be a god send!

    Do you still get that error now in the error log, or is it something else now?
