Dante SOCKS4/SOCKS5 Proxy Server - Hardened

This is a repackaged open source software product wherein additional charges apply for cloudimg support services.

## Overview

Dante is a robust, free circuit-level SOCKS proxy server from Inferno Nettverk. This AMI delivers the sockd daemon as a fully installed, hardened SOCKS4 and SOCKS5 forward proxy you run and control entirely in your own AWS account. An authenticated proxy is serving within minutes of launch - no manual configuration required.

## Why This Image vs. a Manual Install

Exposing a SOCKS proxy safely requires configuring the daemon, authoring an authentication method, writing source access rules to prevent open-relay abuse, and provisioning per-deployment credentials. This image completes every one of those steps at build time. It never ships a default or shared credential and is never an open proxy. Launch the instance, retrieve your unique credential, point your client at port 1080, and you are proxying.

## Security Hardening

This image follows a defence-in-depth approach aligned with industry best practices:

• Authentication enforced: every SOCKS request must present a valid username and password; anonymous and wrong-credential requests are rejected at method negotiation
• No default or shared credentials: a cryptographically random proxy username and password are generated on each instance's first boot and written only to a root-only file
• Not an open relay: source access rules pass only loopback and RFC1918 private ranges by default; everything else is blocked before authentication
• Least privilege: relay children run as an unprivileged account; only a minimal privileged helper reads the password database
• Automatic restart: systemd monitors the daemon and restarts it on failure
• CIS-aligned baseline: the underlying OS is configured with security defaults consistent with CIS benchmark recommendations for Linux

## Application Stack

sockd is installed from the distribution repository and runs under systemd, answering SOCKS4 and SOCKS5 on TCP port 1080. The daemon starts privileged only long enough to authenticate against the system password database, then drops to an unprivileged account for relay children. systemd starts it on boot and restarts it on failure.

## Concrete Use Cases

• Egress control for a private subnet: route outbound traffic from application instances through a single authenticated SOCKS gateway so egress is centralised, logged, and credential-gated
• Secure remote access to internal services: developers tunnel to private-network resources over an authenticated SOCKS5 connection instead of exposing those services directly
• A controlled forward proxy for automation: scrapers, CI runners, and batch jobs proxy through a source-restricted, authenticated endpoint you own rather than a public open proxy

## AWS Integration

Deploy on any EC2 instance type. The proxy listens on port 1080; open that port in your security group only to the client ranges you trust and widen the in-proxy source access rules to match. Back up your configuration with EBS snapshots. Place the instance in a private subnet with a NAT gateway or internet gateway to act as a controlled egress point.

## Getting Started

1. Launch the AMI on your chosen EC2 instance type

2. Retrieve your unique proxy username and password from the root-only credentials file

3. Configure your security group to allow TCP 1080 from your client IP ranges

4. Point your SOCKS-aware client or application at the instance on port 1080

5. Optionally widen source access rules in the configuration file to admit additional client networks

Your traffic is proxied through an authenticated, non-open-relay endpoint you fully control.
