我们在内部物理服务器中托管我们的网站，我们使用的是 Ubuntu Server 16.10。
该网站实际上无法通过域名或公共 IP 地址访问，但当我使用服务器的本地网络（192.168.1.2）时可以访问它。
当我使用 curl 命令通过服务器终端浏览网站（域名或公共 IP）时，它会给出一个 html 页面，其中包含一个表单和一个尝试（代码）fin 和 md5 字符串的 javascript 代码。
我第一次尝试通过 apache site-enabled 更改文档根目录，然后我停止了 apache，但 curl 仍然给我这个 html 页面。我尝试通过 curl ipinfo.io/ip 重新验证我的公共地址，但仍然一样。
我将 html 页面代码移动到我的笔记本电脑上，我在浏览器中运行它，这是一个获取 MD5 哈希的 js 脚本。
请问我要遵循哪些步骤来解决这个问题？
代码如下

看到 Gerald Schneider 的回答后，我确信我的路由器登录页面出现在我的网站上。
为了确定这是路由器的问题，我关闭了服务器，公共 IP 地址仍然显示路由器配置登录页面。
没有 IP 冲突，服务器本地地址是 192.168.1.2，路由器本地地址是 192.168.1.1。
答案1
这看起来不像是被黑客入侵的。它看起来像是您网络上连接设备的登录屏幕。Sagem Communications（在元标记中提到）生产机顶盒、路由器等。我猜您最近在网络上添加了一个设备，并且它的 IP 地址与您的服务器相同。
根据标题标签，该设备是FAST3304-V2路由器。
在不了解您的网络的情况下很难给出建议，我会尝试就您可以做什么提供一些一般提示：
- 确定您是否真的在访问服务器或所述路由器。 如果是路由器，请检查两个设备的网络配置，并确保它们具有不同的网络地址
- 这可能是 DNS 问题，例如路由器将您想要的服务器名称发送到错误的地址。如果是这种情况，应该可以通过定义正确的 DNS 条目轻松修复
- 如果您确实访问了服务器，但服务器仍向您发送路由器登录表单，请检查服务器的配置。httpd 可以配置为代理请求，iptables 可以配置为重定向数据包，可能性有很多
您将必须做更多的调查，如果对您的设置不了解更多，这只是盲目的猜测。
