backupclifeedbackjavascriptjs

Symptoms

  • License cannot be updated with the following message:

    This License is Provided Free of Charge by OsSav Technology Ltd. You can buy a cheap license here to turn off the warning.

  • Custom records for Plesk URLs can be found at /etc/hosts:

    # cat /etc/hosts
    185.50.69.214 ka.plesk.com
    185.50.69.214 id-00.kaid.plesk.com
    185.50.69.214 alternate.ka.plesk.com
    185.50.69.214 feedback.pp.plesk.com

  • The following illegal or fake extension can be found installed from CLI:

    # plesk bin extension -l | grep OsSav
    OsSav - OsSav Technology

Cause

3rd-party illegal License software installed on the server.

Resolution

  1. Connect to the server via SSH

  2. Remove the extension:

    # plesk bin extension --uninstall osSav
    The extension was successfully removed.

  3. Remove custom IPs from /etc/hosts file. Vi editor can be used for this.

  4. Reactivate the license by following instructions from this article

In case such extension is not found, apply these manual removal steps

  1. Connect to the server via SSH

  2. Check for any OsSav configuration files or CronJobs and remove all findings:

    # grep -iR "OsSav" /etc/*

  3. In case the /etc/hosts file cannot be edited check attributes:

    # lsattr /etc/hosts
    ----ia--------e----- /etc/hosts

    3.1. In case the output is like the above example, remove additional attributes:

    # chattr -i /etc/hosts
    # chattr -a /etc/hosts

    Note: Double-check attributes with step 3 to make sure the changes were applied.

  4. Check if there is similar content on the /opt/psa/admin/cp/public/javascript/main.js file and if so, backup the file and remove the found lines:

    OsSavPleskGlobal(1);
    document.onload=OsSavPleskGlobal(1);
    currentPage = location.href;
    setInterval(function(){
    if(currentPage!=location.href){
    currentPage=location.href;
    OsSavPleskGlobal(1);
    }
    },100);
    /** OsSav v1.98 **/

  5. Remove file system attributes from earlier license files:

    # find /etc/sw/keys/keys -type f | xargs -i chattr -ia {}

  6. Remove the pirate license files:

    # rm -rf /etc/sw/keys/keys/*

  7. Install the Plesk license.
