为什么 Fedora 无法启动我的(硬连线)网络?

为什么 Fedora 无法启动我的(硬连线)网络?

我有一块硬连线的以太网卡/电缆连接到我的集线器。我启动了 Fedora 23,但是没有网络,为什么?所以我检查了这张卡是否存在:-

[root@localhost ~]# lspci | grep Ether
00:0b.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8100/8101L/8139 PCI Fast Ethernet Adapter (rev 10)
[root@localhost ~]# lspci -vm -s 00:0b.0
Device: 00:0b.0
Class:  Ethernet controller
Vendor: Realtek Semiconductor Co., Ltd.
Device: RTL-8100/8101L/8139 PCI Fast Ethernet Adapter
SVendor:    Packard Bell B.V.
SDevice:    Device e012
Rev:    10

然后我尝试启动网络(仅供参考,systemctl restart network.service有相同的输出)...

[root@localhost ~]# service network start
Starting network (via systemctl):  Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe" for details.
                                                           [FAILED]

systemctl status network.service建议的命令(上面)的结果是......

[root@localhost ~]# systemctl status network.service
● network.service - LSB: Bring up/down networking

   Active: failed (Result: exit-code) since Sun 2015-11-08 19:40:26 GMT; 30s ago
     Docs: man:systemd-sysv-generator(8)

然后我在这里看到了一些建议,我检查了网络脚本的内容,ifcfg-enp0s11ifconfig -a,上面失败的那个似乎是我正在寻找的那个,MAC地址与该命名设备列出的MAC地址相同

[root@localhost ~]# more /etc/sysconfig/network-scripts/ifcfg-enp0s11 
HWADDR=00:13:D4:86:EB:18
TYPE=Ethernet
BOOTPROTO=dhcp
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=enp0s11
UUID=b7fce5e7-b3aa-4e95-a014-8661889e9cce
ONBOOT=yes

我在网络脚本中的其他选项是

ifcfg-enp0s11  ifdown-ippp  ifdown-routes    ifup          ifup-ipv6   ifup-ppp       ifup-tunnel
ifcfg-lo       ifdown-ipv6  ifdown-sit       ifup-aliases  ifup-isdn   ifup-routes    ifup-wireless
ifdown         ifdown-isdn  ifdown-Team      ifup-bnep     ifup-plip   ifup-sit       init.ipv6-global
ifdown-bnep    ifdown-post  ifdown-TeamPort  ifup-eth      ifup-plusb  ifup-Team      network-functions
ifdown-eth     ifdown-ppp   ifdown-tunnel    ifup-ippp     ifup-post   ifup-TeamPort  network-functions-ipv6

但是ifup eth,,,ifup eth1ifup eth2都说没有找到配置? ifup enp0s11ifup lo

[root@localhost ~]# ifup eth
/usr/sbin/ifup: configuration for eth not found.
Usage: ifup <device name>

我部分地理解这ifup​​些命令实际上不再使用,因为 NetworkManager 正在运行......

[root@localhost ~]# systemctl status NetworkManager.service

知道为什么我没有网络吗?

答案1

尝试这个;

sudo vi /etc/sysconfig/network-scripts/ifcfg-enp0s11

然后更改以下内容;

BOOTPROTO="static"

除非您有特殊原因需要动态设置 IP,否则我会设置静态 IP 地址。这样,网络上的所有其他设备始终具有相同的 IP 可供连接,例如 ssh、http、ftp 等。

IPADDR=路由器设置中的 IP 地址将是您的外部 IP 地址, GATEWAY= 查看您的路由器设置, NETMASK= 查看您的路由器设置, DNS1= 查看您的 路由器设置DNS2= ,查看您的路由器设置,您可以通过在浏览器 URL 中输入路由器的 IP 地址或路由器 IP 来访问路由器。 192.168.1.1在我的 Linksys 路由器上,我转到“状态”选项卡,所有信息都在“路由器”下。将所有这些信息添加到您的ifcfg-enp0s11文件中,然后重新启动网络

sudo systemctl restart network.service

确保它已启用,以便您在重启时保持设置

sudo systemctl enable network.service

您可以使用以下方式检查网络状态

sudo systemctl status network.service
