[EP-tech] Antwort: Re: Virus Scan during Upload

Many thanks Brian,

after solving some initial problems we got it working.

- clamd daemon must be installed and running
- port must be the same as the LocalSocket defined in /etc/clamd.conf
- the clam user running the clamd daemon must be in the same group as the
apache user.

We tested with a text file containing the EICAR signature (
http://www.eicar.org/download/eicar.com.txt )- works fine.
ClamAV does not recognize the EICAR signature enclosed in a pdf file using
a Trojan horse file dropper (
 ), while the Antivirus scanner on my Mac did.

Best regards,

This is what we us in our IR (running EPrints 3.2.8).  It could probably be
written a bit better (obviously ? feel free to tweak as anyone sees fit),
but works as is for us currently.  You will need ClamAV installed
(including the associated PERL modules).

This part goes into the cfg/cfg.d/document_validate.pl file under the
?CHECKS IN HERE? comment but before the ?return ( @problems );?

        # Virus scan the uploaded files.
        my %files = $document->files;
        my $path = $document->local_path;
        while ( my ($filename, $size) = each(%files)) {
                # for each file uploaded
                use File::Scan::ClamAV;
                my $av = new File::Scan::ClamAV(find_all => 1, port=>
                my $filetoscan = "$path/$filename";
                my %caught = $av->scan("$filetoscan");
                while (my ($k,$v) = each %caught ) {
                        # Viruses Found
                        push @problems,
( "validate:virus_found",
                                        filename => $session->make_text
                                        virus => $session->make_text($v) );
        # End Virus scan.

And the HTML Phrase can go into the file cfg/lang/en/validate.xml

<epp:phrase id="validate:virus_found">The file that has been uploaded
contains a virus.  The file in question is: <epc:pin name="filename"/>.  It
contains the virus: <epc:pin name="virus"/>. Please remove the file and
upload a virus free version.</epp:phrase>

Hope this helps or at least points you in a direction as to what you might

Brian Gregg.

Subject: [EP-tech] Virus Scan during Upload


in the course of a Swiss Digital Lifecycle Management Project, we are
evaluating EPrints and our repo according to the POWRR scheme (gap
analysis) to find tools for digital preservation.

One criterion is virus scan of a document before it is uploaded. I have
found this old thread: http://www.eprints.org/tech.php/thread-16755.html

Has anyone followed up on this, implemented a hook and is willing to share

Thank you for all your advice and help.
