Across the Great Wall we can reach every corner in the world
A collection of shell scripts for setting up VPN servers (WireGuard, L2TP), proxies (Xray, V2Ray, Trojan), and server utilities (BBR tuning, benchmarking, encrypted backups). Primarily aimed at users in China circumventing network restrictions, though the individual scripts are useful anywhere.
bench.sh is genuinely useful as a quick VPS evaluation tool — I/O, network speed, and geekbench in one shot. The backup.sh script covers a real need: encrypted MySQL dumps with rclone-to-GDrive transfer, which is a common sysadmin pattern done reasonably well. Docker images for Xray and V2Ray are kept current across multiple Debian/Ubuntu releases, which takes discipline. BBR auto-install still saves time for people spinning up new VPS instances.
The scripts are pure curl-and-run with no integrity verification — no checksums, no signature validation on downloaded binaries, which is a serious problem for tools explicitly used to bypass surveillance. L2TP and PPTP are deprecated in-repo but the scripts are still present and could fool someone into deploying them. No modular structure: every script is a monolithic bash blob that's hard to audit or patch. The README is almost entirely links to a personal blog, which is a fragile documentation strategy.
