up 和 ifdown 的问题 ifup:无法读取接口文件“/etc/network/interfaces”

up 和 ifdown 的问题 ifup:无法读取接口文件“/etc/network/interfaces”

删除网络管理器包并删除 resolvconf 应用程序后,我可以/etc/network/interfaces使用 ifup 和 ifdown 进行管理以及手动管理我的/etc/resolv.conf文件,在尝试启动以太网和无线接口时收到以下错误。

以太网接口:

root@user-computer:/etc/network# ifup eno1

/etc/network/interfaces:21: unknown or no method and no inherits keyword specified
ifup: couldn't read interfaces file "/etc/network/interfaces"

无线接口wlp3s0:

root@user-computer:/etc/network# ifup wlp3s0

/etc/network/interfaces:21: unknown or no method and no inherits keyword specified
ifup: couldn't read interfaces file "/etc/network/interfaces"

以下是重新启动计算机后的步骤 - 首先,当我重新启动时,我的主以太网接口关闭:

步骤1:

root@user-computer:/home/user# ifconfig

lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:65536 Metric:1
RX packets:4 errors:0 dropped:0 overruns:0 frame:0
TX packets:4 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1
RX bytes:240 (240.0 B) TX bytes:240 (240.0 B)

vibr0适用于我的虚拟机。

virbr0 Link encap:Ethernet HWaddr aa:bb:cc:dd:ee:gg
inet addrx.xx.xx.xx Bcastx.xx.255.255 Mask:255.255.255.0
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

第2步:

然后我会尝试提出这个问题:

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

/etc/network/interfaces:21: unknown or no method and no inherits keyword specified

ifup: couldn't read interfaces file "/etc/network/interfaces"

步骤3:

我阅读了我的/etc/network/interfaces文件以确保一切正常:

root@user-computer:/home/user# cat /etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)

auto lo
iface lo inet loopback

#eno1
auto eno1
iface eno1 inet static
address xx.xx.xx.xx
netmask 255.255.255.0
gateway xx.xx.xx.xx
up route add -net xx.xx.0.0 netmask 255.255.0.0 gw xx.xx.xx.xx
up route add -net xx.xx.0.0 netmask 255.128.0.0 gw xx.xx.xx.xx
up route add -net xx.xx.0.0 netmask 255.255.0.0 gw xx.xx.xx.xx
up route add -net xx.xx.0.0 netmask 255.255.0.0 gw xx.xx.xx.xx
dns-nameservers xx.xx.xx.xx xx.xx.xx.xx xx.xx.xx.xx
dns-search local1.local local2.local local2.local local3.local local4.local

# wlp3s0
auto wlp3s0
iface wlp3s0 inet statc
address xx.xx.xx.xx
netmask 255.255.255.0
gateway xx.xx.xx.xx
wireless-essid xxxx
wireless-mode managed

步骤4:

我可以使用以下命令调出界面ifconfig eno1 up

root@user-computer:/home/user#ifconfig eno1 up

root@user-computer:/home/user# ifconfig

eno1 Link encap:Ethernet HWaddr aa:bb:cc:dd:ee:ff
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
Interrupt:20 Memory:f7d00000-f7d20000

步骤5:

我可以让界面运行的唯一方法是运行dhclient eno1

root@user-computer:/home/user# dhclient eno1

root@user-computer:/home/user# ifconfig

eno1 Link encap:Ethernet HWaddr aa:bb:cc:dd:ee:ff
inet addrx.xx.xx.xx Bcastx.xx.xx.xx Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:1535 errors:0 dropped:0 overruns:0 frame:0
TX packets:1274 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:1963415 (1.9 MB) TX bytes:108139 (108.1 KB)
Interrupt:20 Memory:f7d00000-f7d20000

其他事宜:

尝试启动 WiFi:

root@user-computer:/home/user/Downloads# ifup wlp3s0

/etc/network/interfaces:21: unknown or no method and no inherits keyword specified

ifup: couldn't read interfaces file "/etc/network/interfaces"

root@user-computer:/home/user/Downloads# ifconfig wlp3s0 up

SIOCSIFFLAGS: Operation not possible due to RF-kill

最终的:

我需要使用 ifup && ifdown 来控制我的网络接口以及文件,/etc/network/interfaces同时控制我的/etc/resolv.conf文件:

现在我的 dhclient 再次覆盖了 resolv.conf - 我特意删除了 resolvconf 包以停止这种行为。

这是一个错误还是发生了什么事情,我该如何解决这个问题,才能让 ifup 和 ifdown 适用于以太网和 WiFi 接口。
