Disabling SMB server signing on a media server instance

The Server Message Block (SMB) configuration on media server application instances enforces SMB server signing by default. This configuration may cause a performance reduction with Universal Shares. If you see a performance reduction, you can use the following procedure to disable server signing.

Warning:

Disabling SMB server signing leaves the instance vulnerable to man-in-the-middle attacks. Only disable server signing if your instance is in a fully trusted private network.

To disable SMB server signing

  1. Log in to the media server instance as the appadmin user and run the following command to navigate to the SMB configuration file:

    sudo vi /etc/samba/smb.conf

  2. Modify this file to comment out the following entry:
    server signing = mandatory
  3. Run the following command to restart the SMB service:

    sudo systemctl restart smb
