Debian 静态 ip，无法调出界面：“RTNETLINK 答案：文件存在”

我全新安装了 SELKS（Debian 9），并且手动配置了网络，但无法启动接口eno1。

我收到错误：

RTNETLINK answers: File exists
ifup: failed to bring up eno1

我的/etc/network/interface配置如下：

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eno1
iface eno1 inet static
    address 192.168.200.32/24
    gateway 192.168.200.1
    # dns-* options are implemented by the resolvconf package, if installed
    dns-nameservers 8.8.8.8

它是当我在安装程序中单击手动配置网络时由 Debian 安装程序自动生成的，所以我猜它是正确的。

我还注意到该/var/run/network/ifstate文件不包含eno1，并且该ifstate.eno1文件是空的：

root@user:/home/user# cat /var/run/network/ifstate
lo=lo
root@user:/home/user# ls /var/run/network/
ifstate  ifstate.eno1  ifstate.lo
root@user:/home/user# cat /var/run/network/ifstate.eno1 

root@user:/home/user#

即使我尝试手动输入该值，eno1=eno1界面仍然无法启动。

我尝试关闭接口然后打开它，以及刷新接口（ip addr flush dev eno1），但结果是一样的：

root@user:/home/user# ifdown eno1
ifdown: interface eno1 not configured

root@user:/home/user# ifup -vvv eno1

ifup: configuring interface eno1=eno1 (inet)
/bin/run-parts --exit-on-error --verbose /etc/network/if-pre-up.d

RTNETLINK answers: File exists
ifup: failed to bring up eno1

root@user:/home/user# ip addr flush dev eno1
root@user:/home/user# ifup eno1

ethtool -i另外，以下是和的输出dmseg：

我尝试了这里针对该主题提出的几乎所有建议，但仍然找不到任何答案。

任何帮助均感激不尽。

答案1

您之前已手动分配了 IP 地址，但当您尝试启动接口时，地址分配失败。

第二个错误可能是由手动编辑文件引起的/var/run/network/ifstate.eno1。不要这样做！

因此，正确的步骤是：

  • ifdown --force -vvv <iface>
  • ip address flush dev <iface>
  • ip link set <iface> down
  • ifup -vvv <iface>
