go-wireless

A way to interact with the Wireless interfaces on a Linux machine using WPA Supplicant.

Requirements

Requires a running wpa_supplicant with control interface at /var/run/wpa_supplicant.

Usage

Get a list of wifi cards attached:

ifaces := wireless.Interfaces()

From there you can use the client:

wc, err := wireless.NewClient("wlan0")
defer wc.Close()

Get a list of APs that are in range:

aps, err := wc.Scan()
fmt.Println(aps, err)

Get a list of known networks:

nets, err := wc.Networks()
fmt.Println(nets, err)

Connect to networks:

net := NewNetwork("FBI Surveillance Van #4", "secretpass")
net, err := wc.Connect(net)

Disable networks:

nets, err:= wc.Networks()
net, err := nets.Find("FBI Surveillance Van #4")
net.Disable(true)
net, err := wc.UpdateNetwork(net)

Subscribe to events:

sub := wc.Subscribe(wireless.EventConnected, wireless.EventAuthReject, wireless.EventDisconnected)

ev := <-sub.Next()
switch ev.Name {
	case wireless.EventConnected:
		fmt.Println(ev.Arguments)
	case wireless.EventAuthReject:
		fmt.Println(ev.Arguments)
	case wireless.EventDisconnected:
		fmt.Println(ev.Arguments)
}

Check the status of the connection:

st, err := wc.Status()
fmt.Printf("%+v\n", st)

API

There is an API that can be used with gin:

r := gin.Default()
api.SetupRoutes(r)
r,Serve(":8080")
