Technical Details
what runs on :6522Overview
Gobby is an open-source collaborative text editing tool that relies on the libobby protocol for real-time synchronization. It allows multiple participants to work on the same document concurrently with color-coded cursors and selections, providing clarity on contributors' inputs. Communication occurs via TCP connections typically on port 6522.
Protocol & Architecture
libobby handles the synchronization by broadcasting document changes incrementally, minimizing bandwidth requirements and latency. The architecture adopts a peer-to-peer model facilitated through a central server that coordinates sessions and participant states. While primarily designed for local networks, it also functions over the Internet with appropriate network configurations.
Ecosystem Support
Besides Gobby, other editors and tools like Obby and various libobby-integrated applications also leverage this port. The suite is cross-platform, supporting Linux, Windows, and macOS. While feature-rich for text documents, it offers limited capabilities for complex file types and depends heavily on the stability of the underlying TCP session.

security overview
Common Vulnerabilities
- Lack of encryption in default setups, leading to potential eavesdropping and man-in-the-middle (MITM) attacks.
- Absence of built-in authentication exposes sessions to unauthorized access or hijacking.
- Susceptibility to denial-of-service (DoS) if the service is left exposed to the internet without safeguards.
Common Mitigations
- Tunnel Gobby traffic over encrypted channels such as SSH or VPN to ensure data privacy.
- Implement external authentication layers or firewall rules to restrict access to known hosts.
- Avoid exposing port 6522 directly to the public internet; limit access to trusted local networks.
- Regularly update the software to patch emerging vulnerabilities and follow least privilege principles when configuring collaborative sessions.
