🚀 what it does

• SSH-RSA connection to huawei olt terminal (via jsch)
• real-time signal analysis for each PON: captures Tx/Rx levels, calculates averages, and alerts for critical or borderline levels
• PON summary: shows all ont details for the selected primary interface
• search by serial (by-sn): type the ONT/ONU serial and get full info instantly
• drop diagnosis: displays the last 10 disconnection events from each ONT/ONU
• postgresql integration: for user login, roles, and permissions
• clean and responsive UI with JavaFX, styled with CSS

---

📚 libs used

• jsch — SSH access in Java
• javafx — for building the UI
• openpdf — generate nice-looking PDFs
• launch4j — wraps the app into a windows .exe
• postgresql — handles login and role control

🐧 installation on linux

👉 recommended: just download the ready-to-use .zip from the releases section here on github — it's much easier and faster.

running the app on linux is super simple now. here’s the updated process:

1. download the project

clone the repo or get the latest .zip with everything already bundled.

git clone https://github.com/toomazs/NM-OLT-App.git
cd NM-OLT-App-Linux

2. compile and install

just give permission and run:

chmod +x compile.sh
./compile.sh

this will:

• compile the whole project
• generate the OLTApp.jar
• install the icon automatically in your system
• validate the launcher so it appears cleanly in the application menu - just click it

✅ no manual configuration needed.
✅ no root or sudo required.
✅ works on any folder (downloads, desktop, wherever).

3. run the app

you can now:

• open it directly from the application menu (search for “OLTApp”)
• or run manually via:

./run.sh

🛠 database setup (postgresql)

1. create the database:

CREATE DATABASE nm_olt_db;

2. create the users table:

CREATE TABLE usuarios (
  id serial primary key,
  nome text not null,
  usuario text unique not null,
  senha text not null,
  cargo text not null
);

3. insert some default users:

INSERT INTO usuarios (nome, usuario, senha, cargo)
VALUES
  ('intern user', 'intern', 'nm12345678', 'estagiario'),
  ('admin user', 'admin', 'nm12345678', 'supervisor');

🔐 secrets setup

you’ll need two secret files for the app to work:

SecretsDB.java — database connection

package database;

public class SecretsDB {
    public static final String DB_URL = "jdbc:postgresql://localhost:5432/nm_olt_db";
    public static final String DB_USER = "your_db_user";
    public static final String DB_PASSWORD = "your_db_password";
}

📁 save it inside: src/database/

---

Secrets.java — ssh credentials + olt list

public class Secrets {
    public static final String SSH_USER = "your_ssh_user";
    public static final String SSH_PASS = "your_ssh_pass";
    public static final String[][] OLT_LIST = {
        {"OLT_NAME_1", "IP_1"},
        {"OLT_NAME_2", "IP_2"}
    };
}

📁 save it inside: src/ (next to Main.java)
