我有一个 Fedora 机器,使用我的静态 IP 69.169.136.6 等,所有配置都根据 ISP 的要求进行。就在最近,硬盘驱动器出现故障(我应该保留更好的备份)——在恢复过程中,我想在我的 Archlinux PC 上放一个网页来解释这个问题——我目前没有足够的权限来更改分配给域的 DNS 记录。
当我在系统运行时将 IP 地址更改为 69.169.136.6 时,ifconfig 会报告新的 IP 地址,但是http://whatismyip.com/不行。当我更改它并重新启动时,我无法 ping 通 - 我收到的消息是“ connect: Network is unreachable
”(当给出 google.com 的 IP 地址之一时 - 主机名给我ping: unknown host xxx
)。在我可以访问 DNS 系统之前,我该怎么做才能让它正常工作?
编辑:使用新 IP 地址,问题相同,IP 现在是 69.169.136.29。以下命令可能有用:
#ping 69.169.136.1

更新:有新的静态 IP 地址,已验证可以在 Windows 中使用... /etc/rc.conf 的相关部分如下:
#Static IP example

答案1
从你的 IP 路由输出来看,你没有设置默认网关 - 请尝试运行:
ip route add default via 69.169.136.1
我不确定在 archlinux 上是否不同,但在 Redhat 变体上,为了使其永久存在,您可以将以下内容添加到 /etc/sysconfig/network:
GATEWAY=69.169.136.1
答案2
检查您的网络设置:
- 您的网络掩码和广播地址设置正确吗?
- 您的默认网关设置正确吗?
