To open a second port for connecting to a different mobile RAT

To open a second port for connecting to a different mobile RAT through your server, you can follow these steps:

1. Determine which port you would like to open for the new connection. Let's assume you want to use port 9190 for the second RAT.

2. Log in to your server via SSH using a terminal or PuTTY if you are on a Windows system.

3. Once connected, ensure that you have administrative privileges by logging in as the root user or a user with sudo access.

4. Open the firewall configuration to allow incoming connections on the desired port. CentOS 7 typically uses `firewalld` as the firewall management tool. Use the following command to add a new rule for port 9190:

  ```
  sudo firewall-cmd --zone=public --add-port=9190/tcp --permanent
  ```
  This command adds a permanent rule to allow incoming TCP traffic on port 9190.

5. Apply the changes by reloading the firewall rules:

  ```
  sudo firewall-cmd --reload
  ```

6. Verify that the new port is open by checking the firewall status:

  ```
  sudo firewall-cmd --zone=public --list-ports
  ```
  This command will display the list of open ports, including the newly added port 9190.

7. You can now configure your second mobile RAT to use port 9190 for incoming connections. Ensure that the RAT software is properly configured to listen on the new port.

8. Connect to the server using the new port and test the connection to ensure it is working as expected.

Remember to use caution and ensure that you are complying with all legal and ethical considerations when using such software. Unauthorized access to devices and networks is illegal and can have severe consequences.
