可以看到网卡是enp2s0和wlp3s0，wlp3s0是无线网卡.

Examples

  • No passphrase (open network):

create_ap wlan0 eth0 MyAccessPoint

我对应的命令就是

1
sudo create_ap wlp3s0 enp2s0 MyAccessPoint

那么带密码：

  • WPA + WPA2 passphrase:
1
sudo create_ap wlp3s0 enp2s0 MyAccessPoint MyPassPhrase
  • Internet sharing from the same WiFi interface:
1
sudo create_ap wlp3s0 wlp3s0 MyAccessPoint MyPassPhrase

感觉常用的就这三个.

一个禁用笔记本键盘的命令

发现一个linux下禁用键盘的命令

1
sudo rmmod atkbd

临时禁用然后把键盘放在笔记本上，再也不用担心外接键盘压到笔记本按键了。
