• apache2 2.4.18

    sudo apt-get -y install python-software-properties && \
    sudo apt-get -y install software-properties-common && \

• produce vulnerable Diffie-Hellman parameter by sudo openssl dhparam -out /etc/apache2/dhparams512.pem 512
• Change CipherSuites in ClientHello (handshake) (by this) to DHE_EXPORT
