Is tun working on windows? #88
Description
I write a simple piece of test code on windows. after I startup the program, I set ip address of 10.8.0.6 , mask 255.255.0.0
Then I set a route via "route add 192.168.66.0 mask 255.255.255.0 10.8.0.6", then on a console I ping 192.168.66.1 to check if any packet is coming through the tun interface, but I don't see anything related to the ping command.
On the other hand, I used wireshark to capture all the request, seems that the operating system is sending ARP before sending the real traffic.
But, tun only support layer3, how to handle this situation?
test code:
func main() {
tun, err := water.New(water.Config{
DeviceType: water.TUN,
})
if err != nil {
panic(err)
}
bs := make([]byte, 1500)
i := 0
log.SetLevel(log.DebugLevel)
log.Infof("ready to start wireshark on: %s, isTap: %v", tun.Name(), tun.IsTAP())
for {
_, err := tun.Read(bs)
if err != nil {
log.Panic(err)
}
ver := (bs[0] & 0xf0) >> 4
if ver == 4 {
var header ipv4.Header
header.Parse(bs)
log.Infof("src:%s, dst:%s, protocol:%d", header.Src.String(), header.Dst.String(), header.Protocol)
} else if ver == 6 {
log.Infof("get ipv6 package")
} else {
log.Infof("unknown package")
}
i++
}
}
