Should somebody find some Python piece of code running on Windows 7 that succesfully sends a simple TCP packet on the 'Npcap Loopback Adapter', he would be welcome. It is possible to restore the Scapy routing table by calling () after route_add_loopback(), but the result is the same : Wireshark does not sniff the packet on either interface. Note that the call to route_add_loopback() is required, or show_interfaces() won't report the 'Npcap Loopback Adapter', which means that sendp() will fail. Unfortunately, Wireshark does not sniff the packet on either interfaces (the 'Intel(R) Centrino(R) Advanced-N 6235' and the 'Npcap Loopback Adapter'). Sendp(packet,iface='Npcap Loopback Adapter') May somebody give an hint ? Update 1Īs suggested, I tried a more explicit code using sendp() and not send(), since we are talking layer 2 here: route_add_loopback() Moreover, Wireshark does not see anything on the loopback interface. Received 8 packets, got 0 answers, remaining 1 packets Packet = IP(src='127.0.0.1', dst=dstHost)/TCP(dport=dstPort, flags='S')įile "R:/Documents/Projets/python/hacking/scan.py", line 46, in ĪttributeError: 'NoneType' object has no attribute 'display' Added the PnpLockDown directive to the npcap.sys INF file for additional Windows file protection of the driver binary. Now, I'm running the server, and I try to run that piece of code that would just send a SYN to the server with Scapy : from import IP Further deprecate the 'Legacy loopback support' option: The npcapwatchdog scheduled task will not check for the existence of the Npcap Loopback Adapter. Wireshark does report the whole TCP traffic on the loopback interface. Print('Received: %s' % (code('utf-8')))īoth works fine. and I set up this very classic TCP client: import socket S = socket.socket(socket.AF_INET, socket.SOCK_STREAM) The system does only have one wireless network interface plus the Npcap loopback interface. I'm also running Npcap 0.99r7 and Wireshark 2.6.2 on this sytem. I have a problem with a very basic usage of Scapy on Windows 7 (Python 3.6, Scapy 2.4.0).
