![Ubuntu 网络错误(Ubuntu 12.04)](https://linux22.com/image/1050145/Ubuntu%20%E7%BD%91%E7%BB%9C%E9%94%99%E8%AF%AF%EF%BC%88Ubuntu%2012.04%EF%BC%89.png)
我们经营1000BaseT,全双工网络,但是我们使用自动协商以确保错误发生率最低。几天前,所有 Ubuntu 服务器的上传(到外部世界)速度都开始变得极慢,同时保持正常的下载速度。例如,我们通常可能有100 down
和100 up
,但是我们现在将接收100 down
和1 up
。
这仅适用于 Ubuntu 机器,因为所有 Windows 机器(服务器和我的管理笔记本电脑)都可获得全速。
所有 Ubuntu 机器当前都在使用该3.13.0-48-generic
内核(我曾尝试降级内核,但没有解决任何问题)。
以下是我从各种调试工具收集的一些信息:

答案1
今天早上我决定再运行一些调试测试,我发现当我运行 MTR 时,它返回了有关 DNS 解析的错误(左上角有一个微小的错误消息)。我将 DNS 名称服务器设置为 8.8.8.8(Google)和路由器的 IP - 按此顺序(Google 然后是路由器),互联网速度飙升至正常速度。
该问题未在 Windows 上发生的原因是,按照习惯,我在 Windows 机器上自然将第一个名称服务器设置为 8.8.8.8,但对于 Linux 则不是。
我希望这可以帮助任何遇到此问题的人。
