    Just an FYI to everyone ...

    Reading through this thread, I keep seeing the same error over and over ...

    The path "/etc/init.d/ should be "/etc/rc.d/init.d/"!

    I have installed the latest version yesterday, but the IP is neither being blocked in CSF nor logged in the log. Also, I modified the script to include the IP address in the email, but the IP address field is blank in the email. How to fix it?

    Script getting IP from /var/log/messages file. If your FTP server is not logging ftp transactions, IP will not be discovered.

    check your messages log while ftp transfer. If your server adds log line for every connection and every Download and upload script works.

    If you cannot solve the problem please pm me...

    If script is not latest version please update.

    If script is latest version please check your /var/log/messages file for FTP logs. If there is no information about ftp transactions script can not discover attacker's IP address..

    Hello Hidonet,

    shell_exec are not in the List from disable_function.

    The Script works but the User that have a dedicated IP being not blocked if upload virusscripts.

    A User where use the Main-IP for Upload are blocked.

    Greats

    hello,

    that i mean.

    I have make other Tests with infected files:

    Main-IP = xx.xx.xx.05

    User-IP = xx.xx.xx.10

    - User have the same IP like the Server Main-IP => IP blocked

    - User have a dedicated IP on the Server => not blocked



    - User login with as FTP-Host the Main-IP => not blocked

    - User login with as FTP-Host the User-IP => not blocked

    - User login with as FTP-Host his domain.tld => not blocked

    I recieve the Mail with informations but the IP are not blocked and i cann Upload files - the Script move the Files to the quarantine.

    Best regards

    Hello,

    If you dont want to remove shell_exec from disable_function edit ftp_clamscan.php replace first line with :

    #!/var/cpanel/3rdparty/bin/php -d safe_mode="Off" -w -q

    it doesnt seem to be running for me
    No errors when I restart FTP but it doesnt scan an eicar file or a text file with blocked content

    When I restart pure ftp from WHM ( i know to restrt it from ssh ) it shows

    Pure-ftpd (/usr/sbin/pure-uploadscript -B -r /var/run/pure-ftpd/clamscan.sh) running as root with PID 16826

    Which means something is still calling that file


    any ideas ?
