Kali(debian)建立WIFI AP热点

采购识别网卡

经朋友推荐购买的是TOTO LINK的N200UP无线网卡,切记型号版本,芯片RT3070,较为稳定,支持AP模式。
# 查看网卡支持模式与芯片版本
root@kali:~# lsusb
Bus 003 Device 010: ID 148f:3070 Ralink Technology, Corp. RT2870/RT3070 Wireless Adapter

# 查看支持的接口模式
root@kali:~# iw list
Supported interface modes:
     * IBSS
     * managed
     * AP
     * AP/VLAN
     * WDS
     * monitor
     * mesh point

# 其余查看命令等
root@kali:~# nmcli device show
root@kali:~# iwconfig

编辑网络配置文件,添加桥接接口

vim /etc/network/interface
# wireless wlan0
allow-hotplug wlan0
iface wlan0 inet manual

# 重启前须要注释掉下面这行数据 防止br0成了主接口
auto br0
iface br0 inet dhcp
      bridge_ports eth0
      bridge_stp off
      bridge_maxwait 0

重启网卡

service networking restart
service network-manager restart
or
ifconfig wlan0 down

启用AP网络

hostapd /etc/hostapd/hostapd.conf

恢复无接口模式

其实此时不删除br0也同样可以正常上网
删除方式:
# 注释第一步中的代码
vim /etc/network/interfaces

# down掉br0接口
ifconfig br0 down

# 查看解除桥接绑定关系
brctl show
brctl delbr br0

hostapd.conf

# wireless network name                                                                                                               interface=wlan0
# Set your bridge name
bridge=br0
driver=nl80211
country_code=CN
ssid=Cnlouds
hw_mode=g
channel=6
wpa=2
wpa_passphrase=123456
# Key management algorithms
wpa_key_mgmt=WPA-PSK
# Set cipher suites (encryption algorithms)
# TKIP = Temporal Key Integrity Protocol
# CCMP = AES in Counter mode with CBC-MAC
wpa_pairwise=TKIP
rsn_pairwise=CCMP
# Shared Key Authentication
auth_algs=1
# Accept all MAC address 
macaddr_acl=0
