SSH Access and Authentication

This document outlines the SSH access setup for the Hadox infrastructure, covering the VPS and Hostinger shared hosting environments.

1. VPS Access (srv566867)

Provider

  • Host: Hostinger VPS
  • OS: Ubuntu 22.04.5 LTS

SSH Configuration

  • Default SSH port: 22
  • Primary user: root (restricted usage recommended)
  • Limited user: drone (used for CI deployments)

Key-based Authentication

  • SSH keys are used exclusively; password login is disabled.
  • Each key is generated per environment (local, Drone CI, etc.)

Known SSH Keys

Environment Key name User Notes
Local Dev hostinger-deploy ekaropolus For pushing from local to Hostinger
CI/CD drone-hostinger drone Used by Drone CI to pull/push code
Gitea git@hadox.org system System-wide access for Gitea Git

2. Hostinger Shared Hosting

SSH Settings

  • Custom port: 65002
  • SSH user: u594326895
  • Access: Git-based deployment only
  • Restrictions:
  • No root privileges
  • No Docker support
  • Git pull operations permitted from verified remotes

3. Key Management

All SSH keys should be:

  • Generated with ssh-keygen -t ed25519
  • Stored securely (~/.ssh/)
  • Added to appropriate services (e.g., Gitea, GitHub, Hostinger)
  • Documented in this file upon creation

Common SSH Commands

# Test connection
ssh -p 22 root@<vps-ip>

# Add new key to agent
ssh-add ~/.ssh/hostinger-deploy

# Test Git operations
git -c core.sshCommand="ssh -i ~/.ssh/hostinger-deploy -p 65002" pull

Security Recommendations

  • Disable root login for production (future hardening)
  • Rotate keys periodically
  • Avoid password-based authentication
