问题 How can I run a scapy script inside mininet to generate custom packets? I know I could generate traffic using iperf ,netperf etc.But I need to customize the packets and then use them in mininet. Thanks, Regards, Sushmita 回答1: You can generate trafic from hosts. You can run cli commands using xterm. I think that using dpkg-name -v you can see what version is emulated by host. So, you can customize ping or whatever you want from the emulated host! Here you can see how to run commands in hosts

问题 I recently started programming in python and scapy. But when i use from scapy.all import * it doesnt work and i get the exception ImportError: No module named 'base_classes'. So it is finding the folder all, but cannot find base_classes. I verified however that base_classes is actually in there. In extend, import scapy.all.base_classes finds that there are base_classes in there but when i execute it i stil get an error. What should i do? i verified my version of scapy and it is 2.x. Thank you

问题 I recently installed scapy and was trying to start using it and I'm having trouble using the sniff() function. I've been able to install Scapy using the steps described in their docs. I'm running Windows 7 x64 and using Python 2.6. I'm able to use the send family of functions fine (confirmed with Wireshark) but sniff() is failing with the following stack trace: Traceback (most recent call last): File "sniffingStuff.py", line 11, in <module> sniff(filter="ip",prn=customAction) File "C:

问题 I'm trying to build PTPv2 protocol using Scapy. There are few message types in this protocol, so I use ConditionalField to describe the different fields options: class PTPv2(Packet): name = "Precision Time Protocol V2" fields_desc = [ # Header BitField('transportSpecific', 1, 4), BitEnumField('messageType', 0, 4, Message_Types), ByteField('versionPTP', 2), LenField('messageLength', None), ByteField('subdomainNumber', 0), ByteField('empty1', 0), XShortField('flags', 0), LongField('correction',

问题 I've successfully created a DHCP discover, Offer and Request in Scapy. I was wondering if it is possible for me to retrieve the offer DHCP IP address, saving it to a variable where I will be able to request for it specifically in my DHCP Request using Scapy. I've tried using sniff but it doesn't seem to retrieve any IP address as follows : sniff(iface=myiface, filter="port 68 and port 67") Are there any methods to retrieve the offered IP? Thanks 回答1: I've solved this already. For anyone else

问题 vscode said can't find IP in scapy.all but from terminal, i can import it: could somebody tell my why? 回答1: I get exactly the same issue with my Scapy code in VS Code. I think it's to do with the way pylint is working. When you from scapy.all import IP , Python loads scapy/all.py , which includes the line from scapy.layers.all import * . scapy/layers/all.py includes this code: for _l in conf.load_layers: log_loading.debug("Loading layer %s" % _l) try: load_layer(_l, globals_dict=globals(),

问题 I am using Scapy to sniff access point(AP) beacon packets and also getting all AP beacon packets and it's MAC address nearby AP but I need exact MAC address of connected AP then How to sniff only connected AP beacon frame or How to filter connected AP beacon frame using scapy or any alternate idea. *I am doing it in python 2.7 回答1: Assuming the beacon frame is called pkt. pkt.addr1 is the destination MAC, pkt.addr2 is the source MAC and pkt.addr3 is the MAC address of the AP. You could write

问题 I send a arp packet broadcast with this line: send(ARP(op=ARP.who_has, psrc="192.168.5.51", pdst=the_ip)) My question is: How can I view the response (in this case: the mac of the remote ip)? I know I can do: pkt = sniff(filter=arp , count=10) print (pkt.summary()) But I do not want to count the packets because I do not know when it will be printed (could be in the next 10 or 100 packets) Is there a way to while it is sniffing, to print the summary and thus, see the mac adress I am looking
