General help

My 1.7 keeps giving errors too when files are uploaded:

"Clam AV has failed to run. The return error message was There was an unknown error with clam.. Here is the output from Clam:"

But there is no "output" from Clam so haven't clue what's going on there. The path (C:\ClamWin\bin\clamscan.exe) is correct and clam works fine when launched from the server...hmmm

Because I am getting the following error "can't initialize the virus database", I am guessing that this is telling me that my path might need to include the location of the virus database.  Does anyone that runs a Linux server  have any ideas on this problem?

Thanks,

See my earlier post re: fixing Clam AV on windows platforms. I have since worked on a solution, which should (in  theory at least) work on UNIX style platforms, but I have no way to test same as I don't have a UNIX box.

*Requirements

1. your clam directory on the UNIX box has a configuration file (*.conf) in the same directory as the clamscan executable file (/usr/bin ?).

2. the forementioned configuration file has a configuration setting:

database=

, which is the path to the anti-virus database folder

*Instructions

1. Download the attached file 'clamfix.php' to your Moodle /lib directory

2. Make a couple of minor modifications to the 'uploadlib.php' file in the same directory as follows:

2.a) at the top of the file (under the revision information), paste the following:

/**

* modification to addess clam problems

*/

require("clamfix.php");

4. The top of your file should now look something like:

<?php

/**

* uploadlib.php - This class handles all aspects of fileuploading

*

* @author ?

* @version $Id: uploadlib.php,v 1.17.2.2 2006/05/17 18:15:43 skodak Exp $

* @license http://www.gnu.org/copyleft/gpl.html GNU Public License

* @package moodlecore

*/

/**

* modification to addess clam problems

*/

require("clamfix.php");

//error_reporting(E_ALL ^ E_NOTICE);

2.b) In 'uploadlib.php', find the function 'clam_scan_file (the function declaration is around line 586 in version 1.6.1) and insert the modifications highlighted in bold and enlarged text.

function clam_scan_file(&$file, $course) {

global $CFG, $USER;

global $notice;

$notice = '';

if (is_array($file) && is_uploaded_file($file['tmp_name'])) { // it's from $_FILES

$appendlog = true;

$fullpath = $file['tmp_name'];

}

else if (file_exists($file)) { // it's a path to somewhere on the filesystem!

$fullpath = $file;

}

else {

return false; // erm, what is this supposed to be then, huh?

}

$CFG->pathtoclam = trim($CFG->pathtoclam);

$clamdatabasedir = clam_database_dir();

if (!$CFG->pathtoclam || !file_exists($CFG->pathtoclam) || !is_executable($CFG->pathtoclam) || !$clamdatabasedir){

$newreturn = 1;

$notice = get_string('clamlost', 'moodle', $CFG->pathtoclam);

if ($CFG->clamfailureonupload == 'actlikevirus') {

$notice .= "\n". get_string('clamlostandactinglikevirus');

$notice .= "\n". clam_handle_infected_file($fullpath);

$newreturn = false;

}

clam_mail_admins($notice);

if ($appendlog) {

$file['uploadlog'] .= "\n". get_string('clambroken');

$file['clam'] = 1;

}

return $newreturn; // return 1 if we're allowing clam failures

}

$cmd = $CFG->pathtoclam .' '. $clamdatabasedir .' '. $fullpath ." 2>&1";

// before we do anything we need to change perms so that clamscan can read the file (clamdscan won't work otherwise)

chmod($fullpath,0644);

If any UNIX user tests this solution, please reply to this post.
