Gonc – Netcat with P2P Nat Traversal
Gonc is a new tool that combines the basic socket handling of netcat with peer‑to‑peer NAT traversal methods, allowing direct communication between hosts that are behind network address translation devices. By integrating these capabilities, it seeks to make tasks such as debugging, file transfer or simple tunnelling possible without requiring manual port forwarding. The project was highlighted on Hacker News.
