Hi there.

Could someone explain what to do? I thought I understood this concept but it doesn't work so I guess I missed something.

I have a D-Link modem/router (DSL-2740B) and with that you are allowed to create one free DDNS at https://www.dlinkddns.com/login so I created a host name, lets call it hostname.dlinkddns.com , used the IP address that was showing and saved the settings.

I specified this hostname.dlinkddns.com also in my router (ipoe_atm0/atm0) and added a port forward with,

Name: Netduino

Address: 192.168.1.2

External port: 80

Internal port: 80

Protocol: TCP

Wan Interface: atm0

If I type 192.168.1.2 in my browser I get the Netduino webserver (on my local network)

If I type hostname.dlinkddns.com I get to see my routers login page (on my local network)

Outside my local network I do not get a result on hostname.dlinkddns.com

I read on the D-Link forum that some firmware versions do not allow passwords longer than 10 digits (I used 9)

I even deleted the host, reset the modem to factory default and tried again. No result.

The funny thing is, it used to work with an Arduino, so  know its possible. I just cant remember how I did it the first time

Should I use a different port (8080) ?

In my code I use: socket.Bind(new IPEndPoint(IPAddress.Any, 80));

Is there something obvious missing?

Any advise is welcome.

Hi there.

I'm very proud that I got a web server up and running  However, not all text is showing on the html page and I cant figure out why that is. Its like it hangs while loading the page. Does that make sense?

The code I use is copy and paste stuff from other forum members (its the best way for me to learn how it works).

The code I have now and which produces a partial html page is below and I attach a screenshot of the html page.

All help is appreciated

Netduino (plus) 2 project

I'm a beginner, just started coding and was playing with loops, button, LED and piezo element. I created this to understand the code and provide this for beginners like me who have some kind of security system in mind.

It uses the on board LED and button with a piezo element connected on pin 5 (red = +) and GRND (-).

It requires for you to add the PWM.dll to your project reference (right-click on your folder called 'References' and choose 'Add Reference...'). It can be used in combination with a 10K resistor to reduce the volume (I did not use a resistor).

When pressing the button a low frequency sound followed by a higher frequency sound will be heard. The later is looped (counted) and creates the (activation) delay. After the delay (10 loops) the on board LED will go on, indicating the system is activated. You could write additional code there where the LED goes on (for example an output port that enables a relay allowing power to an external siren when a sensor detects an intruder.

You could use an RFID card reader, code- or key lock instead of the on board button.

Its a simple code, just copy and paste and make sure to add the pwm.dll reference to your project.
