PHP 的 HTTP 认证机制仅在 PHP 以 Apache 模块方式运行时才有效，因此该功能不适用于 CGI 版本。

在 _h5ai/public/index.php 最下面增加以下代码：

function mima(){

$user=array('nonni','nonni');

if(!($user[0]===$_SERVER['PHP_AUTH_USER'] && $user[1]===$_SERVER['PHP_AUTH_PW'])){

header('WWW-Authenticate: Basic realm="nonni"');

header('HTTP/1.0 401 Unauthorized');

die("please login");

}

}

在第二行 <?php 的下面插入以下代码：

mima();

OK了。

1. 去https://github.com/gnab/rtl8812au下载驱动，解压。
2. 文件夹中打开终端运行：

make
sudo make install
sudo modprobe 8812au

1. 插入USB网卡，检查Setting --> WiFi。

yum provides ifconfig
yum whatprovides ifconfig
yum install net-tools
yum install traceroute

New:

和ifconfig 显示的一样

ip addr

查看介面传输状态-s是详细显示

ip -s link
ip link

TCP listen

ss -lt

UDP listen
ss -ul

TCP连线
ss -t

traceroute/traceroute6改成tracepath

route改为ip -route

route table 看起来有点不习惯

ip route

route6 IPv6的route table

ip -6 rou

arp改为ip nei查看附件的arp和IPv6的neighbor，这个把v6 v4整合的还不错。

ip neighbor

ifconfig eth1 up
ifconfig eth1 down
