此时并没有看到这个新安装的网卡：

可以看到，ens33这个网卡有异常，好像多了ipv6的信息，应该是一个ipv6的，查看系统日志，看到如下报错：

[1705156203.3089] device (ens33): ipv6: duplicate address check faile

因此，决定关闭ipv6，关闭步骤如下：

1，

删除ens33网卡内的所有关于ipv6的信息，最终该网卡的配置文件如下：

[root@centos10 rtl8188gu-master]# cat /etc/sysconfig/network-scripts/ifcfg-ens33
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
NAME=ens33
UUID=abed039b-c453-47ee-acd4-301974b75aab
DEVICE=ens33
ONBOOT=yes
IPADDR=192.168.123.20
GATEWAY=192.168.123.2
NETMASK=255.255.225.0
DNS1=223.5.5.5
DNS1=223.6.6.6

2，

内核屏蔽ipv6：

[root@centos10 rtl8188gu-master]# cat /etc/sysctl.conf

sysctl settings are defined through files in

/usr/lib/sysctl.d/, /run/sysctl.d/, and /etc/sysctl.d/.

Vendors settings live in /usr/lib/sysctl.d/.

To override a whole file, create a new file with the same in

/etc/sysctl.d/ and put new settings there. To override

only specific settings, add a file with a lexically later

name in /etc/sysctl.d/ and put new settings there.

For more information, see sysctl.conf(5) and sysctl.d(5).

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1

最后两行屏蔽ipv6的，然后sysctl -p  激活此设置

3，

network这个文件末尾添加no

[root@centos10 rtl8188gu-master]# cat /etc/sysconfig/network

Created by anaconda

NETWORKING_IPV6=no

4，

重启网络

[root@centos10 rtl8188gu-master]# systemctl restart NetworkManager
[root@centos10 rtl8188gu-master]# systemctl restart network

5，

重新插拔网卡，再次查看网卡信息，新网卡出来了：

[root@centos10 rtl8188gu-master]# ip a

现在需要连接WiFi了，有很多方法，比如上面资料里提到的wpa_suppliant_withoutopenssl-master，或者直接在桌面图形化方式连接

本次采用桌面方式，因此，先安装一个桌面：

yum group install “GNOME Desktop”

安装完毕后，startx命令进入桌面：

此时的网卡还没有激活，因此，激活先，看到网卡里有一个up就可以啦：

[root@centos10 rtl8188gu-master]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000

扫描WiFi热点：

或者使用iwlist命令（这个命令以后再说，现在只是演示一下）：

OK，扫描热点完毕后，就可以在桌面看到所有WiFi了，然后点击自己的WiFi，输入密码连接就可以了，我的WiFi名称是  mywif：

密码输入后，就可以看到网卡的ip了：

[root@centos10 wireless_tools]# ip a

查看系统日志，可以看到网卡如何连接的：

自我介绍一下，小编13年上海交大毕业，曾经在小公司待过，也去过华为、OPPO等大厂，18年进入阿里一直到现在。

深知大多数网络安全工程师，想要提升技能，往往是自己摸索成长，但自己不成体系的自学效果低效又漫长，而且极易碰到天花板技术停滞不前！

因此收集整理了一份《2024年网络安全全套学习资料》，初衷也很简单，就是希望能够帮助到想自学提升又不知道该从何学起的朋友。

既有适合小白学习的零基础资料，也有适合3年以上经验的小伙伴深入学习提升的进阶课程，基本涵盖了95%以上网络安全知识点，真正体系化！

由于文件比较大，这里只是将部分目录大纲截图出来，每个节点里面都包含大厂面经、学习笔记、源码讲义、实战项目、讲解视频，并且后续会持续更新

如果你觉得这些内容对你有帮助，可以添加VX：vip204888 （备注网络安全获取）
