Linedump

CLI-only text pastebin service.

Issue tracker | Libera Chat #linedump

• Status: Beta - expect minor changes
• Instance: linedump.com
• Inspired by:
  • 0x0.st
  • transfer.sh

Note: content is stored unencrypted on the server - consider it public! - Use client-side encryption example in Usage section.

---

Features

Available:

• save and share content via CLI
• up- and download in CLI possible
• rate-limits
• optional auth token for paste creation
• logging

Ideas:

• integrated retention/purge function

Not planned:

• GUI (work around possible, WIP)
• media besides text (abuse potential and moderation effort too high - there are other projects for it available)

Installation

Important

Production Deployment: Use a reverse-proxy (nginx, caddy) with TLS/HTTPS! Rate-limiting and logging features require the X-Real-IP header from a reverse proxy to function correctly. Less critical for local or trusted environments.

Docker

Simple / Testing

docker run -d -p 127.0.0.1:8000:8000 -v /path/to/uploads:/app/uploads git.uphillsecurity.com/cf7/linedump:latest

Open http://127.0.0.1:8000

More advanced example with Podman

podman run --replace -d --restart=unless-stopped \
    --name linedump \
    -e BASEURL="https://linedump.com" \
    --userns=keep-id \
    --read-only \
    --cap-drop=ALL \
    --security-opt no-new-privileges:true \
    -p 127.0.0.1:8000:8000 \
    -v linedump:/app/uploads \
    git.uphillsecurity.com/cf7/linedump:latest
