Display number of blocked malicious IP addresses on OLED display using Photon

Social Project Share

I have a honeypot that collects the IP addresses of the offenders. It in turn sends the data to a BGP server and distributes that list to all of the company and customer routers. I wanted a way to visualize the current number of blocked IP addresses. The router sends the information to the Photon with the API utilizing the Particle.function feature.

OLED Display on Amazon

Photon Code:

#include <Adafruit_SSD1306.h>
#include <string.h>

#define OLED_RESET D4
Adafruit_SSD1306 oled(OLED_RESET);

String strData;

void setup() {
    
Particle.function("oled",dataDisplay);

oled.begin(SSD1306_SWITCHCAPVCC, 0x3C);  // initialize with the I2C addr 0x3D (for the 128x64)
oled.clearDisplay();
oled.display();

}

void loop() {
  
}

int dataDisplay(String command) {
    strData = String(command);
    oled.clearDisplay();
    oled.setTextSize(2);
    oled.setTextColor(WHITE);
    oled.setCursor(0,0);
    oled.print("Blackholed");
    oled.setTextSize(4);
    oled.setCursor(0,25);
    oled.print(strData);
    oled.setTextColor(BLACK, WHITE);
    oled.display();
}

Mikrotik Code: (ROS 6.39 or newer)

:local bgpPrefixCount [/routing bgp peer get [find] prefix-count];
:global lastbgpPrefixCount;

# Check to see if lastbgpPrefixCount variable is null and if so set to 1
:if ($lastbgpPrefixCount~"^\$") do={
:set lastbgpPrefixCount 1;
} else {
 :log info "BGP Prefix is not NULL"
}

:if ($bgpPrefixCount != $lastbgpPrefixCount) do={
:log info message="$bgpPrefixCount";
/tool fetch mode=https  keep-result=no http-method=post url=https://api.particle.io/v1/devices/YourDeviceID/oled http-data="access_token=YourAccessToken&params=$bgpPrefixCount"
:set lastbgpPrefixCount $bgpPrefixCount;
:log info message="BGP Prefix Count Updated"
} else={
:log info message="BGP Prefix Count Unchanged";
}

@nrobinson2000, Thanks for your comment. I updated the post with the Photon and ROS code.
