Send SYN packet failed on Windows 10 about libtins HOT 8 OPEN

I have same exception on win11 I think this is a socket limitation Raw sockets not allowed to work on 10 and 11

@ahmedtalaat327 You're right. Confirmed by more than one ways. At last, I introduce Npcap into my project and work like a charm.

I think its possible to send the UPD carrying the TCP sender.

@WorstCodeWay I think this works

Sorry, where is Port Scan.exe from? Is it built from Tins example source code?

this is the same libtins yeah But using EthernetII instead of sending packet directly
` EthernetII eth = EthernetII("a0:8c:fd:61:5a:1d","94:08:53:64:6c:63") / IP("192.168.100.140", "192.168.100.45") / TCP(100, 1521) / Tins::RawPDU("I'm payload!");;

// Retrieve a pointer to the stored TCP PDU
TCP* tcp = eth.find_pdu<TCP>();
tcp->set_flag(Tins::TCP::SYN, 1);
tcp->seq(1733878791);
tcp->ack_seq(0);



// You can also retrieve a reference. This will throw a
// pdu_not_found exception if there is no such PDU in this packet.
IP& ip = eth.rfind_pdu<IP>();



// The sender
PacketSender sender;
//sender.send(eth, iface);
// Send and receive the response.
(sender.send(eth, iface));`

Interesting! I tried very like this, but without raw payload field, and it didn’t work. I will try this later.

Besides, in practice, you need target MAC address to fill the first parameter of EthernetII constructor, how will you get that? In my case, broadcast arp message may help.
