Tunnelling TCP through a file
This program can be used to tunnel TCP connections through a file. People have used it for interesting things: - Bridging connections which would otherwise be blocked by a firewall - Tunneling through RDP (similar to an SSH tunnel) - Exposing a localhost web server to others Key features I put effort into: 1. The shared file is restarted every 10 MB, so it doesn't grow indefinitely. 2. Optimisations for latency & bandwidth. (800 Mbps on a Gigabit LAN. 108 Mbps if file tunneling through RDP) 3. Synchronisation between two sides (each side can be started and restarted in any order) I'd love to…

In plain words
Tunnelling TCP through a file is a program that routes TCP connections through a shared file, enabling users to bypass firewall restrictions, tunnel connections through RDP similar to SSH tunnels, or expose local web servers. It manages file size by restarting the shared file every 10 MB, supports synchronization between both sides that can be started in any order, and delivers optimized performance reaching 800 Mbps on a Gigabit LAN or 108 Mbps through RDP tunneling.

I've frequently found myself using [nvitop](https://github.com/XuehaiPan/nvitop) to diagnose GPU/CPU contention issues. The two best things about it are: - It's easy to install if I can access pip in the container - It makes a compelling screenshot (which helps me communicate with coworkers.) With those two lessons in mind: Here is Sping! Purpose: Help observe and diagnose latency issues at layer 4+ (TCP/HTTP/HTTPS) Two good things about it: - It's easy to install if you have pip.
