    frp

    frp

    A Fast Reverse Proxy

    frp stands for exactly what it is: a fast reverse proxy. It helps you expose a local server behind a NAT or firewall to the Internet. It is currently under development, but already supports TCP and UDP, as well as HTTP and HTTPS protocols where requests can be forwarded to internal services by domain name. It also has a P2P connect mode and many other nifty features. These include configuration files, environment variables, a dashboard that shows you frp's status and proxies' statistics information, an Admin UI that helps you check and manage frpc's configuration, and many others.

    Pingtunnel

    Pingtunnel

    Pingtunnel is a tool that send TCP/UDP traffic over ICMP

    Pingtunnel is a Go-based tunneling tool that sends TCP and UDP traffic over ICMP. It is designed for experimental, research, and network-study scenarios where ICMP transport is being explored as an alternative path for traffic forwarding. The project uses a client and server model, with the server typically requiring a publicly reachable host. It can carry application traffic through ICMP echo-style communication, which makes it distinct from common TCP, UDP, HTTP, or DNS tunnel tools. ...

    RKN Block Checker

    RKN Block Checker

    Diagnose RKN/TSPU internet blocks layer by layer (DNS, TCP, TLS, HTTP)

    RKN Block Checker is a small Python CLI for diagnosing whether the current network connection is affected by Russian RKN or TSPU blocking. It tests blocking behavior layer by layer instead of only reporting that a site is unreachable. The tool can help distinguish DNS poisoning, TCP reset behavior, TLS DPI based on SNI, and ISP stub pages. This makes it useful for developers, system administrators, network researchers, and censorship-measurement workflows. It is designed as a console utility with straightforward installation and optional proxy support. Its main value is giving users a structured way to understand what kind of network interference is occurring rather than relying on vague connectivity symptoms.

    File Tunnel

    File Tunnel

    Tunnel TCP connections through a file

    File-Tunnel is a tunneling tool that moves TCP connections through a shared file or file server. It is built around the unusual idea that two systems can exchange network data by reading and writing files that both sides can access. This makes it useful in environments where direct TCP connectivity is blocked but a shared folder, FTP server, S3-compatible storage, Dropbox folder, RDP drive share, or similar file channel is available.
