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. πŸ› 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. 🌐 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)

To install packages or make web requests through a proxy on port 12345:

pip install: Use the --proxy flag:pip install --proxy http://127.0.0.1:12345 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 πŸ”‘ 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?

Is this for a specific app (like Chrome, Python, or a game)?

Step 2: Configure Squid to Listen on Port 12345

Edit the Squid configuration file:

sudo nano /etc/squid/squid.conf

Find the line that says http_port 3128 (default port). Change it to:

http_port 12345

If you want to allow all incoming connections (for testing only), add or modify the ACL:

acl all src 0.0.0.0/0
http_access allow all

For Windows Users

  1. Download a proxy client: Choose a reputable proxy client software, such as CCProxy or Proxy Server.
  2. Install the software: Follow the installation prompts to complete the setup.
  3. Configure the proxy settings: Enter the proxy server address, port number (12345), and authentication details (if required).
  4. Connect to the proxy server: Establish a connection to the proxy server using the configured settings.

Step 3: Allow Port 12345 in Windows Firewall

5. Verification Commands

1. Overview

The instruction proxy 12345 install typically refers to setting up a listening proxy server on TCP port 12345 and integrating it into the operating system’s network stack (i.e., "installing" it as a system-wide or session proxy). This is common for debugging HTTP traffic, chaining proxies, or routing applications through a local tunnel (e.g., Shadowsocks, mitmproxy, Squid, or a custom SOCKS/HTTP proxy).

2. Upstream Proxy Chaining

Route your proxy 12345 through another proxy:

cache_peer 10.0.0.1 parent 8080 0 no-query default
never_direct allow all

Step 1: Update System and Install Squid

sudo apt update && sudo apt upgrade -y   # Debian/Ubuntu
sudo apt install squid -y
