Crabbot

A bot that returns you A and RDNS records. Like that:

Dependencies

• JDK 8 (I guess... I actualy using AdoptOpenJDK 14)
• Maven
• Telgrambots library

Getting started

1. Clone repository. If you using an IntelliJ IDEA, you can grab all project directly from GitHub by link. 2. Add telegrambots dependency in your pom.xml:

<dependency>
    <groupId>org.telegram</groupId>
    <artifactId>telegrambots</artifactId>
    <version>4.8.1</version>
</dependency>

3. Define bot username and token in BotIdentifier class (use Telegram's @BotFather to get it).

private static final String USERNAME = "botname";
private static final String API_TOKEN = "JgLM5Jyhq8fFeVUur5442UXbdZR39YkMf4sN7kT4qNKyab";

It's not right way to store token. Best way — store it outside your code or pass it in args. That's feature not implemented here. Feel free to implement it yourself.

3. Build it any available method and run. I use an artifact (JAR) build with IntelliJ IDEA.

3a. [Optional] If you want to use a proxy for your bot, start Tor or Tor Browser and uncomment this lines in Main class:

System.getProperties().put("proxySet", true);
System.getProperties().put("socksProxyHost", "127.0.0.1");
System.getProperties().put("socksProxyPort", "9150");

3b. [Optional] If you deploy bot to VPS, you probably want to run it in the background. You can use nohup for that, but better way would be a Systemd service.

1. Create in *.service file in /etc/systemd/system/. For example it would be crabbot.service.
2. Your service may look like that:

   [Unit]
   Description=Manage Java crabbot service
   [Service]
   WorkingDirectory=/var/www/telegrambots/crabbot/
   ExecStart=/bin/java -jar CrabBot.jar
   User=crabbot
   Type=simple
   Restart=on-failure
   RestartSec=10
   [Install]
   WantedBy=multi-user.target
   

3. Save crabbot.service file, restart systemd, enable service and start it:

   $ sudo systemctl daemon-reload
   $ sudo systemctl enable crabbot.service
   $ sudo systemctl start crabbot.service

Now your bot runs in background, automaticly restarts on failure and after server reboot.
