vallumd

vallumd 本程序允许您集中和分发 IP 黑名单。 如果您在互联网上维护一个服务器，很有可能会遇到一两次暴力破解攻击。没关系，只需安装 fail2ban 即可搞定。 但是，如果您运行着多个服务器，每个服务器都有各自的 fail2ban 实例，那么它们封禁的 IP 地址列表将各不相同。难道不想所有 fail2ban 实例共享一个封禁列表吗？或者，如果您所有的机器都位于您自己控制的路由器或防火墙后面，难道不想在网络边缘就拦截恶意流量吗？ 这正是 vallumd 可以帮助您实现的目标。 工作原理 Vallumd 连接到 MQTT 代理，读取包含 IP 地址的消息，并将这些 IP...
