Pingtunnel is a tool that send TCP/UDP traffic over ICMP
Role in this project:Back-end Developer
Back-end DeveloperContributions:30 releases, 1 review, 334 commits in 3 years 10 months
Contributions summary:Xin appears to be primarily focused on implementing the core functionality of the `pingtunnel` tool. Their commits demonstrate the creation of both server and client components that transmit TCP/UDP traffic over ICMP. They are involved in establishing connections, handling data transfer, and likely addressing low-level network interactions using Go's `golang.org/x/net/icmp` library. The user implemented the initial structure of the server and client and added the core logic for these components.
