• Setting Up an OpenVPN Server on DigitalOcean

    OpenVPN is a powerful open-source solution for creating a private VPN server. In this guide, we’ve walked through the process of installing and configuring an OpenVPN server on DigitalOcean’s cloud service. With an OpenVPN server, you can secure your internet connection and securely access a virtual private network from anywhere.

    Step 1: Create a Droplet on DigitalOcean

    1. Visit the DigitalOcean website and log in to your account or create a new one.
    2. Once logged in, click on “Create Droplet” to create a new virtual machine.
    3. In the Droplet creation interface:
      • Choose the Linux operating system you want to use (e.g., Ubuntu 20.04 LTS).
      • Select the Droplet type based on your needs.
      • Choose a Data Center Region near you.
      • Enable the “Private Networking” option if you want to activate private connections between your Droplets.
    4. Below, you can add optimization options for your Droplet, but it’s not necessary for this purpose.
    5. Click “Create Droplet” at the bottom of the page to create the new Droplet. DigitalOcean will create the server and email you the login information.

    Step 2: Access the Droplet and Update the OS

    1. Use SSH to access your Droplet. Use the public IP address of your Droplet and the SSH key (if used) for authentication:ssh root@your_droplet_ip
    2. Once logged in, update the operating system with the following commands: apt update apt upgrade

    Step 3: Install OpenVPN

    1. Install the necessary packages for OpenVPN with the following command:apt install openvpn easy-rsa
    2. Copy the sample configuration files for Easy-RSA: make-cadir ~/openvpn-ca cd ~/openvpn-ca
    3. Set up environment variables for Easy-RSA:source vars
    4. Initialize the Certificate Authority (CA) and create a series of certificates and security keys: ./clean-all ./build-ca
    5. Create private keys and certificates for the OpenVPN server:./build-key-server server
    6. Copy the sample configuration files for the server:openvpn –genkey –secret keys/ta.key

    Step 4: Configure OpenVPN Server

    Create a configuration file for the OpenVPN server. You can use the following sample configuration as a starting point (server.conf):

            proto udp
            dev tun
            ca /etc/openvpn/easy-rsa/keys/ca.crt
            cert /etc/openvpn/easy-rsa/keys/server.crt
            key /etc/openvpn/easy-rsa/keys/server.key
            dh /etc/openvpn/easy-rsa/keys/dh2048.pem
            server 10.8.0.0 255.255.255.0
            ifconfig-pool-persist ipp.txt
            push "redirect-gateway def1 bypass-dhcp"
            push "dhcp-option DNS 8.8.8.8"
            push "dhcp-option DNS 8.8.4.4"
            keepalive 10 120
            tls-auth /etc/openvpn/easy-rsa/keys/ta.key 0
            cipher AES-256-CBC
            comp-lzo
            user nobody
            group nogroup
            persist-key
            persist-tun
            status openvpn-status.log
            verb 3
        

    Step 5: Start OpenVPN Service

    Start the OpenVPN service using the following command:

            systemctl start openvpn-server@server.service
        

    Enable OpenVPN to start on boot:

            systemctl enable openvpn-server@server.service
        

    Conclusion

    By following the steps outlined in this guide, you’ve successfully set up an OpenVPN server on DigitalOcean. This server allows you to create a secure and private VPN, giving you the ability to protect your internet connection and access a virtual private network from anywhere. You can now further configure your OpenVPN server and connect to it from your devices to enjoy a secure online experience.

  • Using Cloud GPU with Linode VPS for Hashcat

    Using Cloud GPU with Linode VPS for Hashcat

    Cloud computing has revolutionized the way we handle data and perform complex tasks. One of the exciting developments in the cloud computing space is the availability of cloud-based Graphics Processing Units (GPUs). These powerful GPUs can accelerate a wide range of applications, including password cracking using tools like Hashcat. In this blog post, we’ll explore how you can harness the power of cloud GPUs using Linode’s VPS hosting services for Hashcat.

    Why Cloud GPUs Matter

    Hashcat is a popular password cracking tool that leverages the parallel processing capabilities of GPUs to break password hashes quickly. Traditional CPUs may not provide the necessary speed for efficient password cracking. This is where GPUs, especially cloud GPUs, come into play, offering high performance and faster results for Hashcat and similar applications.

    Using Linode’s VPS for Hashcat

    Linode offers VPS (Virtual Private Server) hosting services known for their reliability and performance. With data centers in multiple locations worldwide, Linode provides a solid foundation for hosting cloud-based GPU solutions for Hashcat.

    Getting Started

    Here are the steps to get started with using Hashcat on Linode’s VPS with a cloud GPU:

    1. Sign Up for Linode: If you don’t already have a Linode account, sign up for one. Linode offers a variety of VPS plans to choose from.
    2. Choose a Data Center: Select a Linode data center location that suits your needs and is geographically closer to your target audience or users.
    3. Create a Linode: Create a Linode instance, and choose a Linux distribution that you’re comfortable with.
    4. Install GPU Drivers: To utilize the GPU power, you need to install the appropriate GPU drivers. The specific installation steps can vary depending on the GPU model and the Linux distribution you choose.
    5. Install Hashcat: Install Hashcat on your Linode VPS and set it up according to your password cracking needs.
    6. Start Cracking: Utilize the power of the cloud GPU by running Hashcat commands and cracking password hashes efficiently.

    Example: Cracking Passwords with Hashcat

    Let’s say you have a file named `password_hashes.txt` containing password hashes you want to crack and a dictionary file named `dictionary.txt` containing a list of words and strings to try. You can use Hashcat as follows:

    hashcat -m [hash_type] -a 0 [hash_file] [dictionary_file]
    

    – `-m`: Specify the hash type you’re targeting (e.g., `-m 0` for MD5). – `-a`: Set the attack mode. Use `0` for dictionary attack. – `[hash_file]`: Provide the file containing the password hashes (e.g., `password_hashes.txt`). – `[dictionary_file]`: Specify the dictionary file with words and strings (e.g., `dictionary.txt`). Here’s a practical example using Hashcat to crack MD5 password hashes from a file named `md5_hashes.txt` using a dictionary attack with a wordlist named `common_passwords.txt`:

    hashcat -m 0 -a 0 md5_hashes.txt common_passwords.txt
    

    Hashcat will attempt to crack the MD5 password hashes in `md5_hashes.txt` using the words and strings from `common_passwords.txt`.

    To crack a WPA2 password using Hashcat with a dictionary attack using the module 22000, you would use the following command:

    ./hashcat -m 22000 handshake.hccapx wordlist.txt
    

    Benefits of Using Linode for Hashcat with Cloud GPUs

    There are several advantages to using Linode for your Hashcat password cracking needs with cloud GPUs:

    • Reliability: Linode’s VPS hosting is known for its uptime and reliability, ensuring your Hashcat tasks run smoothly.
    • Scalability: Linode allows you to easily scale your GPU resources up or down as needed, making it cost-effective for various Hashcat projects.
    • Global Data Centers: Linode’s global presence allows you to deploy Hashcat instances closer to your target, reducing latency for password cracking tasks.
    • Comprehensive Documentation: Linode offers detailed guides and documentation to assist you in setting up and optimizing your Hashcat environment with cloud GPUs.

    Conclusion

    Leveraging cloud GPUs for password cracking using tools like Hashcat can significantly accelerate your tasks and provide faster results. Linode’s VPS hosting services offer a reliable and scalable platform to harness the power of cloud GPUs for Hashcat and similar applications. Explore the possibilities of cloud GPUs with Linode, and take your password cracking projects to the next level.
