To install or use a proxy on port 12345, the method depends on whether you are setting up a server, configuring an application, or using a client tool. π οΈ Proxy Server Setup (pproxy)
If you want to run a local proxy server on your machine using Python, the pproxy library is a common choice. Install: pip install pproxy
Run Server: pproxy -l ss://:12345 (starts a Shadowsocks server on port 12345). Run with Encryption: pproxy -l ss://chacha20:key@:12345. π Configure System/Browser
To route your existing internet traffic through a proxy server already running on port 12345:
Windows: Go to Settings > Network & internet > Proxy. Under Manual proxy setup, click Set up and enter the IP (e.g., 127.0.0.1) and Port 12345.
macOS: Go to System Settings > Network > Proxies and enter the server address and port 12345.
Chrome: Chrome typically uses your system's settings. You can access these via Settings > System > Open your computer's proxy settings. Python (pip and requests) proxy 12345 install
To install packages or make web requests through a proxy on port 12345:
pip install: Use the --proxy flag:pip install Requests library: Pass the proxy dictionary in your script:
proxies = "http": "http://127.0.0.1:12345", "https": "http://127.0.0.1:12345" requests.get("http://example.com", proxies=proxies) ``` Use code with caution. Copied to clipboard π Key Port Details
Port 12345: Often used as a default port for custom proxy tools like pproxy, NetBus, or private VPN tunnels.
Security: Ensure your firewall allows traffic on port 12345 if you are hosting the proxy for external use. To give you the most accurate steps, could you tell me: Are you hosting a proxy or connecting to one?
Which operating system (Windows, Linux, macOS) are you using? To install or use a proxy on port
Is this for a specific app (like Chrome, Python, or a game)?
If you just need a simple example to experiment with, here's a basic HTTP proxy server written in Python that you can run:
from http.server import BaseHTTPRequestHandler, HTTPServer
from urllib.request import Request, urlopen
class ProxyRequestHandler(BaseHTTPRequestHandler):
def do_GET(self):
url = f"http://self.path[1:]" # Remove leading '/'
req = Request(url, headers='User-Agent': 'Proxy')
response = urlopen(req)
self.send_response(200)
self.end_headers()
self.wfile.write(response.read())
def run(server_class=HTTPServer, handler_class=ProxyRequestHandler, port=12345):
server_address = ('', port)
httpd = server_class(server_address, handler_class)
print(f'Starting httpd on port port...')
httpd.serve_forever()
if __name__ == "__main__":
run(port=12345)
This is a highly basic example. For production environments or more complex scenarios, consider established proxy software.
You can now configure your browser or bot to use this proxy:
You have successfully installed and configured the proxy on port 12345.
If you prefer SOCKS5 instead of HTTP proxy, use Dante or Shadowsocks. Example with Dante (/etc/danted.conf): Example: Simple HTTP Proxy Server with Python If

Download the source code:
Go to the official repository or use wget. As of recent versions, you can download the latest stable release directly.
cd /tmp
wget https://github.com/z3APA3A/3proxy/archive/refs/tags/0.9.4.tar.gz
(Note: You can check GitHub for the latest version number and replace 0.9.4 accordingly.)
Extract the files:
tar -xzf 0.9.4.tar.gz
Compile and Install: Navigate to the extracted folder and compile the binary.
cd 3proxy-0.9.4
make -f Makefile.Linux
Move the binary to a system path: This makes it easier to run 3Proxy from anywhere.
sudo mkdir -p /etc/3proxy
sudo cp src/3proxy /usr/bin/
sudo privileges).acl CONNECT method CONNECT + delay_pools.127.0.0.1:12345 and use SSH tunneling for remote access:
ssh -L 12345:localhost:12345 user@proxy-server
sudo apt upgrade squid or update CCProxy.Below is a comprehensive, step-by-step guide to install, configure, and verify a generic proxy service named "Proxy 12345". Iβll assume "Proxy 12345" is a stand-in for a TCP proxy listening on port 12345; adapt paths, package names, and commands to your actual proxy software (e.g., Squid, HAProxy, TinyProxy, Nginx stream, or a custom binary). The guide covers Linux (Debian/Ubuntu and CentOS/RHEL), macOS, and Windows, plus Docker, basic troubleshooting, security hardening, and common client configurations.
Warning: Running a publicly reachable proxy can expose your network and data. Apply the security recommendations below before exposing services to the internet.
