我的 Gentoo 机器上的网络工作正常。建立一个连接,一切正常,速度正常。但唤醒速度较慢;启动连接需要时间。即使 ping localhost 也需要很长时间(大约 5 秒)。
有什么想法可以让它变得更快吗?
一些命令的输出:

答案1
由于localhost
和127.0.0.1
给出了不同的响应时间,这是一个名称解析问题。检查/etc/resolv.conf
以确保它包含您的名称服务器的正确地址。如果您不确定正确的地址,您可以尝试
名称服务器 8.8.8.8 名称服务器 8.8.4.4
有点奇怪,localhost
不能从 中的条目解析/etc/hosts
,因此您可能需要检查它是否包含看起来像这样的行
127.0.0.1 本地主机
