Here's a basic script to download IPK files. This example assumes you have a list of IPK files you want to download from a specific repository.
import os
import requests
from urllib.parse import urljoin
def download_ipk(base_url, ipk_files, output_dir):
"""
Download IPK files from a specified base URL.
Parameters:
- base_url: The base URL of the repository.
- ipk_files: List of IPK filenames to download.
- output_dir: Directory where IPK files will be saved.
"""
# Ensure output directory exists
os.makedirs(output_dir, exist_ok=True)
for ipk_file in ipk_files:
url = urljoin(base_url, ipk_file)
filepath = os.path.join(output_dir, ipk_file)
try:
response = requests.get(url, stream=True)
response.raise_for_status() # Raise an exception for HTTP errors
with open(filepath, 'wb') as file:
for chunk in response.iter_content(chunk_size=8192):
file.write(chunk)
print(f"Downloaded ipk_file successfully.")
except requests.exceptions.RequestException as e:
print(f"Error downloading ipk_file: e")
# Example usage

base_url = "http://example.com/ipk-packages/"
ipk_files = ["package1.ipk", "package2.ipk"]
output_dir = "./downloaded_ipks"
download_ipk(base_url, ipk_files, output_dir)
Years ago, .ipk was the file extension for Cydia packages (Iphone Debian Package). This is now largely obsolete. download ipk files
If you are running a development build of OpenWrt (nightly), you need the snapshot repository:
OpenWrt is the most common user of the IPK format. Their official servers mirror all packages for every version and architecture. Here's a basic script to download IPK files
From your computer's terminal:
scp /path/to/local/file.ipk root@192.168.1.1:/tmp/
You need the exact URL for the package. You have two options: Years ago,
Option A: The Online Index (Recommended)
Visit the official OpenWrt package repository:
https://downloads.openwrt.org/releases/
Navigate to:
[Your Version] -> targets -> [Your Target] -> [Your Subtarget] -> packages
Option B: Use opkg to get the URL
If your router has internet temporarily, run:
opkg download [package_name]
This saves the IPK to your current directory. Then, SCP it off the router for backup.
