scan FTP uploaded files on cpanel servers

Posted by Rishikesh Vispute Categories: cpanel, security

This Howto will help you virus can all uploaded via FTP to make sure all files are virus free:

First lets install clamAV , it has been now been included in Cpanel/WHM you can do so from your WHM interface as root by clicking on : Cpanel —> Manage Plugins —> on clamavconnector
Check the “Install and Keep Updated” and then click at the bottom of the page save.

After install finishes edit the file /etc/pure-ftpd.conf and change this line to look like this :

CallUploadScript yes

Next create file /etc/pure-ftpd/clamav_check.sh with this content :

#!/bin/bash
#Maximum file size to scan in bytes that's set to 10MB
MAXSIZE=10485760
if [ "$UPLOAD_SIZE" -le "$MAXSIZE" ]; then
/usr/bin/clamdscan --remove --quiet --no-summary "$1"
fi

Change its permissions so its executable :

chmod 755 /etc/pure-ftpd/clamav_check.sh

Now we should start the pure-uploadscript daemon to call our script every time a file is uploaded

/usr/sbin/pure-uploadscript -B -r /etc/pure-ftpd/clamav_check.sh

And to let it start with your server/vps reboots just run this :

echo “/usr/sbin/pure-uploadscript -B -r /etc/pure-ftpd/clamav_check.sh” >> /etc/rc.d/rc.local

Now restart pure-ftpd :

service pure-ftpd restart

Now all your uploaded files which are less than 10MB in size will be scanned , adjust this size limit per your needs
