More Tailscale tricks for your jailbroken Kindle

Original Article ↗ Hacker News Discussion ↗

Jailbroken Kindle owners are using tools like Tailscale and KOReader to turn aging e-readers into highly customizable, networked devices with features such as dark mode, SSH access, cloud and Calibre integration, and even LLM-assisted reading. Commenters weigh the trade-offs: privacy and metadata logging concerns with Tailscale, potential battery drain and confusing UIs, and the legal/technical constraints of proprietary platforms, while also sharing alternatives like headscale, WireGuard obfuscation, and other e-ink or Android reader setups. Overall, the thread highlights a broader trend of repurposing locked-down consumer hardware into flexible, self-hosted reading and homelab clients.

Tailscale, Privacy, and Network Restrictions

  • Several comments urge adding --no-logs-no-support to tailscaled to avoid client metadata logging (connection endpoints, ports, timestamps).
  • Others note you can self-host a coordination server (e.g., Headscale) to keep Tailscale the company out of the loop entirely.
  • Some report WireGuard is blocked or unreliable in countries like China, Iran, Russia, and UAE, while Tailscale sometimes still works. Roaming vs local SIM routing behavior is discussed.
  • Tailscale is suspected to be a battery hog on mobile platforms and possibly on e-readers.

KOReader and E‑Reader UX

  • Many are very enthusiastic about KOReader: extensive customization, better typography and status bars, advanced front‑light controls, dark mode on older devices, custom dictionaries, SSH server, OPDS/Calibre/cloud/Syncthing integration, and broad device support (Kobo, Kindle, Android, reMarkable, Supernote).
  • Plugins add features like bookshelf/library-style views, reading progress sync, Syncthing, LLM-based explanations/translations, and Goodreads-like integrations.
  • Others find KOReader’s UI confusing and overcomplicated, with poorly organized settings and a “file explorer” style library they dislike. Some prefer stock, opinionated firmware with minimal fiddling.
  • Several note KOReader doesn’t replace stock firmware and can be launched as an app, easing experimentation.

Jailbreaking Kindles and Alternatives

  • Jailbreaking is motivated by missing features (notably dark mode on certain Paperwhites) and the desire to use KOReader and library DRM (ACSM) without new hardware.
  • There is confusion and regret about updating firmware: manual/OTA updates can block jailbreaks, so some recommend disabling updates and waiting for new exploits.
  • One user reports Kindle battery and stability issues after combining KOReader, SSH, and Tailscale.
  • Some prefer not to jailbreak if stock experience is “good enough”; others see jailbreaking plus Tailscale/SSH as enabling fully remote, hands-off management.

Device Trust, Licensing, and Other Hardware

  • Owners of Boox devices express concern about trusting Chinese-made hardware on sensitive networks; others question whether this is consistent given widespread Chinese electronics.
  • Boox is criticized for not releasing Linux kernel sources as required by the GPL.
  • For old or school-locked Chromebooks, suggestions include ChromeOS Flex, mrchromebox-based Linux installs, and PostmarketOS; but a managed/locked device may block these paths.

Miscellaneous

  • Some share resource-constrained Tailscale ports (Rust implementations, ESP32) and speculate about LLMs aiding future jailbreaks, while others note secure bootroms may remain unbreakable.
  • A few dismiss the whole project as overkill compared to simply reading physical books.
