This How-to will help you to scan virus uploaded via FTP to make sure all files are virus free:
First let’s install ClamAV, it has been now been included in Cpanel/WHM. Clam AntiVirus (ClamAV) is a free and open-source, cross-platform antivirus software tool-kit able to detect many types of malicious software, including viruses. One of its main uses is on mail servers as a server-side email virus scanner.
You can also install it from your WHM interface as root as follows:
Step 1: Click on ‘cPanel’ in ‘WHM’
Step 2: Click on ‘Manage Plugins’
Step 3: Now Click on ‘clamavconnector’
Check the “Install and Keep Updated” and then click at the bottom of the page to save.
After the successful installation edit the file /etc/pure-ftpd.conf and change this line to 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 and make it executable:
chmod 755 /etc/pure-ftpd/clamav_check.sh
Now we should start the pure-uploadscript daemon every time to call our script when 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.
