I'm having problems getting a piece of code that works on linux to work on windows.

I'm sending some raw TCP packets and to initalize the socket, i'm doing this on linux:

package main
import (
"net"
)
func main() {
_, err := net.ListenPacket("ip4:tcp", "0.0.0.0")
if err != nil {
panic(err)
}
}

If I run this on windows, I get "panic: listen ip4:tcp 0.0.0.0: bind: An invalid argument was supplied."

If I change the parameters of ListenPacket to net.ListenPacket("ip4:tcp", "0.0.0.0:0"), I get

"panic: listen ip4:tcp: GetAddrInfoW: No such host is known.".

I tried every possible combination of parameters for net.ListenPacket, from specifying my local ip to

specifying a port, to changing the net parameter to whatever i could think of.

Anyone has an insight?

I also tried running as admin, and tried multiple windows machines and all the same result.

That case looks like it is under tested in the net package tests.
Having said that, the documentation for ListenPacket does not list
"ip4:tcp" as a permitted network.

Please consider raising an issue, golang.org/issue
