Log Pages Denied by SquidGuard? (SOLVED)



  • Hi,
    I was wondering if someone had already tested the option on squid to get the deny logs from squidguard?

    Just not sure where to add the

    $sge_prefix = (preg_match("/\?/", $cl['u']) ? "&" : "?");
    $str[] = '< iframe > src="'. $cl['u'] . $sge_prefix . 'sgr=ACCESSDENIED" width="1" height="1" > < /iframe >';
    
    

    then it says

    Hint: You MUST remove extra spaces in the above iframe HTML tags.

    spaces as in```
    <iframe>src="'. $cl['u'] . $sge_prefix . 'sgr=ACCESSDENIED" width="1" height="1" ></iframe> ';

    
    not sure where to add it on the sgerror.php
    
    This is what i got what i got on my sgerror.php

    This programm processed redirection to specified URL or generated error page for standart HTTP error code.

    Redirection supported http and https protocols.

    ----------------------------------------------------------------------------------------------------------------------

    Format:

    #        sgerror.php?url=[http://myurl]or[https://myurl]or[error_code[space_code]output-message][incoming SquidGuard variables]

    Incoming SquidGuard variables:

    #        a=client_address
    #        n=client_name
    #        i=client_user
    #        s=client_group
    #        t=target_group
    #        u=client_url

    Example:

    #        sgerror.php?url=http://myurl.com&a=..&n=..&i=..&s=..&t=..&u=..
    #        sgerror.php?url=https://myurl.com&a=..&n=..&i=..&s=..&t=..&u=..
    #        sgerror.php?url=404%20output-message&a=..&n=..&i=..&s=..&t=..&u=..

    ----------------------------------------------------------------------------------------------------------------------

    Tags:

    #        myurl and output messages can include Tags
    #                [a] - client address
    #                [n] - client name
    #                [i] - client user
    #                [s] - client group
    #                [t] - target group
    #                [u] - client url

    Example:

    #        sgerror.php?url=401 Unauthorized access to URL [u] for client [n]
    #      sgerror.php?url=http://my_error_page.php?cladr=%5Ba%5D&clname=%5Bn%5D // %5b=[ %d=]

    ----------------------------------------------------------------------------------------------------------------------

    Special Tags:

    #      blank    - get blank page
    #        blank_img - get one-pixel transparent image (for replace banners and etc.)

    Thank you

    EDIT: solved

    You need to add exactly like this

    [code] $sge_prefix=(preg_match("/?/",$cl['u'])?"&":"?");
            $str[] = '<iframe src="'.$cl['u'].$sge_prefix.'sgr=ACCESSDENIED" width="1" height="1"></iframe>';[/code]

    and match it like this find the line [code]$str[] = [/code]
    [code]$sge_prefix=(preg_match("/?/",$cl['u'])?"&":"?");
            $str[] = '<iframe src="'.$cl['u'].$sge_prefix.'sgr=ACCESSDENIED" width="1" height="1"></iframe>';
            $str[] = '';[/code]

    Then go to squid ACL and put this on the blacklist

    [code]sgr=ACCESSDENIED[/code]

    Then put pfSense as http for it to work and reboot it and your good to go Remeber will only log to sarg reports the http sites that show the block sign NOT the HTTPS because it will still block it but shows error page IF your running WPAD[/u][/u][/s][/i]**</eod<br>

    EDIT: solved

    You need to add exactly like this

     $sge_prefix=(preg_match("/\?/",$cl['u'])?"&":"?");
            $str[] = '<iframe src="'.$cl['u'].$sge_prefix.'sgr=ACCESSDENIED" width="1" height="1"></iframe>';
    

    and match it like this find the line```
    $str[] =

    $sge_prefix=(preg_match("/?/",$cl['u'])?"&":"?");
            $str[] = '<iframe src="'.$cl['u'].$sge_prefix.'sgr=ACCESSDENIED" width="1" height="1"></iframe>';
            $str[] = '';

    I'm confused.  Where exactly in the file is this supposed to go?  "and match it like this find the line" doesn't makes sense.  Can you post your resulting sgerror.php file?  that might be helpful



  • go to your sgerror.php

    edit it and find the line

    $str[] = '';
    

    Then after you find the line your going to add this ABOVE THIS LINE like this

     $sge_prefix=(preg_match("/\?/",$cl['u'])?"&":"?");
            $str[] = '<iframe src="'.$cl['u'].$sge_prefix.'sgr=ACCESSDENIED" width="1" height="1"></iframe>';
    
    

    Save it then go back to squid and go to the ACL tab look for blacklist and add this

    sgr=ACCESSDENIED

    Hope this helps and dont forget to hit Thank you



  • PfSense 2.3.2 sgerror.php doesn't have the line: $str[] = '';

    So where would I place this: 
    $sge_prefix=(preg_match("/?/",$cl['u'])?"&":"?");
    $str[] = '<iframe src="'.$cl['u'].$sge_prefix.'sgr=ACCESSDENIED" width="1" height="1"></iframe>';

    in sgerror.php?



  • can you attach the sgerror.php



  • This is from /usr/local/www/sgerror.php in Pfsense 2.3.2p1.
