KOS工具箱 is a collection of Shell scripts for Linux CentOS. The official site explicitly supports CentOS 6 and CentOS 7, with a primary focus on Kangle/easypanel, 宝塔, and VPS operations. It provides one-click installation commands and includes features such as template installation, password resets, security hardening, backups, anti-CC protection, and IP blocking.
In terms of feature coverage, KOS is more like an operations script bundle for specific hosting panel ecosystems than a general-purpose DevOps platform. Free features include changing the SSH port, disabling Ping, resetting the Kangle/easypanel administrator password, resetting MySQL/MariaDB passwords, installing templates, fixing some easypanel issues, and FTP backups. The commercial version adds Kangle/宝塔 anti-CC protection, KOS cloud anti-CC, KOSwall, anti-scanning and brute-force protection, illegal content inspection, email alerts for resource usage monitoring, IP whitelist synchronization, automatic IP banning/unbanning, and more. Overall, it leans toward security protection for webmasters.
The official site says KOS commercial licenses can be purchased online, but the main text does not disclose pricing, license duration, machine limits, or after-sales SLA. On the open-source side, there is no visible code repository, license, or audit information, so it is not possible to confirm whether it is open source. For a server tool that requires executing scripts with root privileges, transparency and security documentation remain insufficient.
The advantages are simple deployment, one-command execution from the command line, and features that closely match the needs of Kangle/easypanel users. It is especially suitable for small sites dealing with anti-CC protection, password recovery, template changes, and common fixes. The drawbacks are that system support is limited to the older CentOS 6/7, and information about modern distributions, containerization, CI/CD, APIs/SDKs, and similar areas is missing. The documentation is mainly menu-style instructions and lacks risk warnings, rollback plans, and complete configuration examples.
KOS is suitable for Chinese-speaking webmasters, VPS users, small hosting providers, and operations staff still using Kangle/easypanel or 宝塔. It is less suitable for teams that need standardized, auditable, cross-platform automation. For access from China, the official site uses a .cn domain and provides cn.kos.f2k.pub as an alternative download address, so based on the text it should be directly accessible. Payment methods are not disclosed. Alternatives include 宝塔 security plugins, Fail2ban, CSF/LFD, Nginx/OpenResty rate-limiting scripts, or Cloudflare/WAF.
