freshclam 警告:“DNS 记录已超过 3 小时。”

freshclam 警告:“DNS 记录已超过 3 小时。”

我最近运行了以下命令:

sudo freshclam

输出结果如下:

ClamAV update process started at Mon Sep 28 18:45:04 2015

那么,其中的所有警告是什么意思?我需要做些什么来处理它们吗?或者这完全是服务器端的问题?

答案1

您的 DNS 存在问题,freshclam我们只是就此发出警告......

(线索就在标签里WARNING;-) :P

由于您没有提供任何 DNS 信息,所以很难确定问题的确切来源(我甚至不会称之为问题),但可能您的 ISP 不会频繁刷新其 DNS 解析器。

2 个选项:

  1. 手动将 DNS 更改为维护更好的 DNS(例如这里是一个列表,取 ping 值最低、可靠性最高的一个)
  2. 联系你的 ISP,抱怨,并推荐他们这里告诉他们你有一个173000用户的博客,你会把他们暴露为糟糕,不太可靠ISP 和或许他们会采取措施,以便您和您 ISP 的所有用户都能受益。
