SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Setting up persistent services like SSH on Termux fails frequently due to Android battery optimizations, Google Play versus F-Droid build differences, and platform incompatibilities with Python packages, leaving users with servers that die after reboot or screen-off. ## Core Features & Use Cases - SSH Server Setup: Install and configure OpenSSH on port 8022 with key-based authentication, authorized_keys setup, and config validation via sshd -t. - Boot Automation: Deploy auto-start scripts in ~/.termux/boot/ with termux-wake-lock and EXIT-trap cleanup so sshd survives reboots and screen-off without leaking wake-locks. - Python Package Workarounds: Bypass pip's manylinux wheel rejection on Android by using Termux repo packages, PYTHONPATH exports, or manual wheel extraction. - Use Case: You want to SSH into your Android phone from your laptop at any time. This Skill walks through installing openssh, deploying keys via heredoc (since write_file blocks ~/.ssh/), creating a boot script, and disabling battery optimization so the connection survives reboots. ## Quick Start Set up an SSH server on my Termux installation that starts automatically at boot and survives screen-off.

Frequently Asked Questions about termux-setup

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I set up an SSH server in Termux on Android?▼

Install openssh with pkg, generate an ed25519 key pair, copy the public key to ~/.ssh/authorized_keys, and configure sshd_config to listen on port 8022 with pubkey authentication. Validate the config with sshd -t before starting the server.

How to auto-start sshd at boot in Termux?▼

Place an executable script in ~/.termux/boot/ that starts sshd and holds termux-wake-lock with an EXIT trap to release it. On Google Play builds this works natively; F-Droid builds require the separate Termux:Boot app installed and opened once.

Why does sshd stop working after reboot or screen-off in Termux?▼

Android battery optimization kills Termux background processes, which is the most common cause. Disable battery optimization for Termux in system settings, add it to never-sleeping apps on Samsung devices, and hold termux-wake-lock while sshd runs.

Why does pip install scipy fail in Termux?▼

pip detects sys.platform as android and rejects manylinux wheels, then fails compiling from source due to missing Fortran compilers. Install python-scipy from the Termux repo instead and expose it to your venv via a PYTHONPATH export in the activate script.

What is the difference between Google Play and F-Droid Termux builds?▼

Google Play builds since 2024.10.24 merge Termux:Boot and Termux:Widget into the main app, so separate termux-boot packages fail to install. F-Droid builds require separate apps but offer more reliable background execution for always-on services.

Why can't I write SSH keys to ~/.ssh/ with write_file?▼

write_file has a credential guard that refuses writes to ~/.ssh/ directories. Use a terminal heredoc with a single-quoted delimiter like cat > ~/.ssh/key << 'EOF' instead, then chmod 600 and verify the key with a test SSH connection.
