Just found out that Ubuntu 24.04 server doesn’t use dhclient anymore and uses dhcpcd instead for obtaining dhcp address leases.
To renew your dhcp address, do the following:
sudo dhcpcd -k
sudo dhcpcdThat’s it, Enjoy!

I needed a local instance to play around with phpBB, which I couldn’t find recent docker files for, so I just created my own. The below are the docker-compose.yml and Dockerfile for the latest version of phpBB as of now; 3.3.14.
Note: Make sure to change the variables inside the environment section in the docker-compose.yml file before installation.
# Use the official PHP image with Apache
FROM php:8.2-apache
# Install required PHP extensions and dependencies
RUN apt-get update && apt-get install -y \
wget \
mariadb-client \
unzip \
&& docker-php-ext-install mysqli pdo pdo_mysql \
&& docker-php-ext-enable mysqli pdo pdo_mysql \
&& apt-get clean && rm -rf /var/lib/apt/lists/*
# Enable Apache modules
RUN a2enmod rewrite
# Set working directory
WORKDIR /var/www/html
# Download and extract phpBB
RUN wget https://download.phpbb.com/pub/release/3.3/3.3.14/phpBB-3.3.14.zip && \

You might have rendering issues with WSLg apps, especially in case you are using an Intel graphics card, like this:
In that case, just configure an environment variable named LIBGL_ALWAYS_SOFTWARE and set it to 1. To persist it, add this line inside /etc/profile:
export LIBGL_ALWAYS_SOFTWARE=1
Just restart (using wsl --shutdown for example).
Note: This will disable GPU acceleration for those GUI apps, which I don’t really care about in this case!
Tested on Windows 11 Pro host with Ubuntu 24.04 WSL guest.
That’s it, Enjoy!

I wrote a simple python script that allows you to communicate with the ChatGPT API, the workflow is as straight-forward as this:
Prerequisites:
pip install openai)Limitations:
Here is the code in its simplest form: https://github.com/ahmedatawfik/usefulscripts/blob/main/chatgptcomm.py
import openai
# This is a dummy key, replace with your actual OpenAI API key
openai.api_key = "9i-wmcxtsO-VuDJlPsbRlR9sqWfdLphxFEedbFIyw3MFHlcbtcTapxj6v4CfwmEtarZQWJ0ieEJXSCBHOEM5LP6m-Kd1KVfvuOKPBP8MAeVlvXQsudk8"
# Function to read the prompt from prompt.txt
def read_prompt_from_file(file_path):
with open(file_path, 'r', encoding='utf-8') as file:
prompt = file.read()
return prompt
# Function to write the response to response.txt
def write_response_to_file(file_path, response):
with open(file_path, 'w', encoding='utf-8') as file:
file.write(response)
# Function to get response from ChatGPT
def get_chatgpt_response(prompt):
response = openai.chat.completions.create(
model="gpt-4o",
messages=[
{"role": "system", "content": "You are a helpful assistant who provides cool answers!"},
{"role": "user", "content": prompt}
]
)
return response.choices[0].message.content.strip()
# Main function to read, get response, and write
def main():
prompt = read_prompt_from_file(r"/home/user/prompt.txt")
response = get_chatgpt_response(prompt)
write_response_to_file(r"/home/user/response.txt", response)
print("Response has been written to response.txt")
if __name__ == "__main__":
main()That’s it, Enjoy!
