我的 Ubuntu 网络服务器提供错误的内容

我的 Ubuntu 网络服务器提供错误的内容

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。
