    My English not good enough to explain but I can upload RS project from Windows to Linux over internet easily.

    @Mikhail Today I realized how simple NPort in TCP mode. Thank you.

    Not actually NPort device I use here but a GSM modem from Moxa with a serial port. With a private IP from GSM operator, the only option to access it is via OnCell Central Manager. OCM map the serial port to a local TCP port.

    At least we have 2 options to run RS with SSL even with a negative impact if exists. Nginx + Mono FastCGI will be perfect for RS but I have multiple application run under Apache for now.

    Run Mono FastCGI via Nginx behind Apache (even Apache behind Nginx must be better):

    1. Install Nginx:

    sudo apt-get install nginx

    2. Change Nginx default port from 80 to 8008 and add /scada-fastcgi virtual path:

    sudo nano /etc/nginx/sites-available/default

    	listen 8008 default_server;
	listen [::]:8008 default_server;
    	location /scada-fastcgi {
		index index.html index.htm default.aspx Default.aspx;
		fastcgi_index index.htm;
		fastcgi_pass 127.0.0.1:9000;
		include /etc/nginx/fastcgi_params;
	}

    3. Edit Nginx FastCGI parameter:

    sudo nano /etc/nginx/fastcgi_params

    fastcgi_param  PATH_INFO          "";
fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;

    4. Edit Apache config and reload it:

    sudo nano /etc/apache2/sites-enabled/default-ssl.conf

        	ProxyPass /scada-fastcgi http://127.0.0.1:8008/scada-fastcgi
    	ProxyPassReverse /scada-fastcgi http://127.0.0.1:8008/scada-fastcgi

    sudo systemctl reload apache2

    5. Install Mono FastCGI if needed, run it:

    sudo apt-get install mono-fastcgi-server
    fastcgi-mono-server4 /applications=/scada-fastcgi:/var/www/html/scada/ /socket=tcp:127.0.0.1:9000

    6. Start Nginx:

    sudo systemctl reload nginx

    You can access SCADA web at https://yourserver/scada-fastcgi

    No problem here, I can access for example http://scada.myserver.com/ without a redirect. But to be honest, I’m not expert in Apache configuration.

    I think run scada web as web root for my server is not a good idea since I also use it for different service.

    1. Edit scada-xsp4 config:

    sudo nano /etc/xsp4/scada.webapp

    <apps>
  <web-application>
    <name>scada</name>
    <vpath>/scada</vpath>
    <path>/opt/scada/ScadaWeb</path>
  </web-application>
</apps>

    2. Edit Apache config:

    sudo nano /etc/apache2/sites-enabled/default-ssl.conf

        	SSLProxyEngine on
    	SSLProxyVerify none
    	SSLProxyCheckPeerCN off
    	SSLProxyCheckPeerName off
    	SSLProxyCheckPeerExpire off
    	ProxyPreserveHost off
    	ProxyRequests off
    	ProxyVia off

    	ProxyPass /scada http://127.0.0.1:8000/scada
    	ProxyPassReverse /scada http://127.0.0.1:8000/scada

    3. Disable scada web in Apache:

    sudo a2dissite scada.conf

    4. Restart scada-xsp4 service:

    sudo service scada-xsp4 stop
    ps ax –> to check mono pid that load xsp4.exe
    sudo kill -9 pid_from_previous_step
    sudo service scada-xsp4 start

    5. Restart Apache:

    sudo service apache2 restart

    I can’t edit my previous post, you can test previous configuration by accessing for example https://scada.rapidscada.org/ after restarting Apache web server:

    sudo service apache2 restart

    For my future references:
    1. Run Apache and Nginx together: http://kbeezie.com/apache-with-nginx/
    2. Mono and Nginx: https://www.mono-project.com/docs/web/fastcgi/nginx/

    PART 2: Apache configuration

    Depend on your server configuration, my working /etc/apache2/sites-enabled/default-ssl.conf configuration:

        	SSLProxyEngine on
    	SSLProxyVerify none
    	SSLProxyCheckPeerCN off
    	SSLProxyCheckPeerName off
    	SSLProxyCheckPeerExpire off
    	ProxyPreserveHost off
    	ProxyRequests off
    	ProxyVia off

    	ProxyPass / http://127.0.0.1:8000/
    	ProxyPassReverse / http://127.0.0.1:8000/

    I believe Nginx must be better but since somehow mono-xsp4 available on my Ubuntu system:

    PART 1: mono-xsp configuration

    1. Copy /etc/init.d/mono-xsp4 as /etc/init.d/scada-xsp4 and modify it:

    sudo cp /etc/init.d/mono-xsp4 /etc/init.d/scada-xsp4
    sudo nano /etc/init.d/scada-xsp4

    #! /bin/sh

exit 0

    2. Copy /etc/default/mono-xsp4 as /etc/default/scada-xsp4 and modify it:

    sudo cp /etc/default/mono-xsp4 /etc/default/scada-xsp4
    sudo nano /etc/default/scada-xsp4

    # Defaults for mono-xsp4, official version
# sourced by /etc/init.d/scada-xsp4

# Should we start it?
start_boot=true

# User and group by default
user=www-data
group=www-data

# Default port
port=8000
address=0.0.0.0

# Directory for config files
config_files=/etc/scada-xsp4

    3. Copy /etc/xsp4/debian.webapp as /etc/xsp/scada.webapp and modify it:

    sudo cp /etc/xsp4/debian.webapp /etc/xsp4/scada.webapp
    sudo nano /etc/xsp4/scada.webapp

    <apps>
  <web-application>
    <name>scada</name>
    <vpath>/</vpath>
    <path>/opt/scada/ScadaWeb</path>
  </web-application>
</apps>

    4. Activate scada-xsp4 service and start it:

    cd /etc/init.d/
    sudo chmod +x scada-xsp4
    sudo update-rc.d scada-xsp4 defaults
    sudo service scada-xsp4 start

    5. Open http://localhost:8000 on your browser for testing

    https://store.chipkin.com/products/tools/cas-modbus-scanner has a feature to scan available device address.

    Why not just set it as a virtual com port using https://www.waveshare.com/wiki/File:USR-VCOM_V3.7.1.520.7z and test the communication using a Modbus tester application first.

    I just want to confirm GrafanaDataProvider works good so far. Please remember to release official build.

    Usually I use a Modbus tester application to confirm Modbus RTU/TCP communication. You can try https://store.chipkin.com/products/tools/cas-modbus-scanner or https://github.com/ed-chemnitz/qmodbus
