OpenDNS IP Updater

This Python script updates your IP address with OpenDNS.

Setup

1. Installation

1. Python Installation: Ensure you have Python installed on your system. You can download it from the official Python website.

2. Dependencies Installation: Install the necessary Python packages by running the following command:

   pip install requests
   

2. Configuration

1. Edit Configuration File: Open the configuration file (config_file) in a text editor and fill in the required information:

   • login: Your OpenDNS login username.
   • password: Your OpenDNS account password.
   • server: The OpenDNS server URL (updates.opendns.com).
   • networkname: The name of the network to update (e.g., Home).

2. Set Paths: Set the paths to your configuration file (config_file) and the file to store the previous IP address (previous_ip_file) in the script.

Usage

1. Run the Script: Open a terminal or command prompt, navigate to the directory where the script is saved, and run the script using the following command:

   python script_name.py
   

   Replace script_name.py with the name of the Python script file.

2. Check Log File: After running the script, check the log file (opendns_update.log) to verify the script's execution status and any updates made to the IP address.

Additional Notes

• Logging: The script logs its actions to the opendns_update.log file in the same directory as the script. Check this file for detailed information about the script's execution.

• Execution Frequency: Depending on your needs, you may want to schedule the script to run periodically using a scheduler (e.g., cron on Linux, Task Scheduler on Windows) to ensure your IP address is updated regularly.

• Security: Keep your configuration file (config_file) secure, especially if it contains sensitive information such as your OpenDNS account password.

Troubleshooting

• Error fetching current IP address: HTTPSConnectionPool(host='api64.ipify.org', port=443): Max retries exceeded with url: / (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x75e45250>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution')): If you encounter this error fetching the current IP address, follow these troubleshooting steps:
  1. Check your internet connection.
  2. Verify DNS configuration:
     • Linux: Check /etc/resolv.conf and make sure the DNS is properly set. If it isn't, edit the .conf with addresses to a DNS server.
     • Windows: Set IPv6 DNS in network settings.
  3. Restart DNS service or flush DNS cache:
     • Linux: Restart networking or systemd-resolved service.
     • Windows: Run ipconfig /flushdns and restart your computer.
  4. Test DNS resolution using nslookup api64.ipify.org again.
  5. Temporarily disable firewall or security software and test again.
  6. Check router DNS settings or try using a different DNS service.
