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. -

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. -

rr
Record and Replay Framework
rr aspires to be your primary C/C++ debugging tool for Linux, replacing — well, enhancing — gdb. You record a failure once, then debug the recording, deterministically, as many times as you want. The same execution is replayed every time. rr also provides efficient reverse execution under gdb. Set breakpoints and data watchpoints and quickly reverse-execute to where they were hit. rr works on real applications and is used by many developers to fix real bugs.
