I would need to add ESP() layer using scapy as seen below for creating a custom ipsec packet, but whenever i tried to append/add the ESP() layer it throw a message says ESP not defined. Can anyone help me how to add/import the ESP layer in scapy .
q = IP(dst="192.168.0.6")/ESP(spi=5)/TCP()
q.show2()
Can anyone help me out here.. Appreciate for your support
Thanks
This works out of the box with Scapy's current development version. You should probably upgrade your Scapy install from the Github repository.
By the way, which version of Scapy are you using? Do you get any warning message when running Scapy?

I'm using the mDNS protocol implementation on lWIP, I need to add subtype for an mDNS service i'v created, but there is not any function or macro that could be used to set the subtype of a service. (thing existes in the standards and many other mDNS implementations on linux), Does anyone have an idea or the same issue before ?
thanks in advance
After some researchs in the mdns and dns-sd standards with a light understanding of your mDNS implementation, i found a solution to implement it, actually it should be added as PTR RR answer to mdns output packet.
I tested it many times and it works perfectly, So that resolve my problem.
Here is a pull request i'v done in the Github LwIP repository :
https://github.com/lwip-tcpip/lwip/pull/7
Otherwise you can check the patch based on the master branch in the link bellow :

I was using WSL to run ROS commands, and at a point i had to enable system to respond to broadcast icmp requests (for a multi master kind of a setup) i.e. on linux i had to make sure
cat /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts
returns 0. but WSL does not contain such a file, so i was thinking of enabling it on windows. All the sources i have gone through suggest me to add a rule to firewall but my system is not responding to broadcast ping even when my system's firewall is turned off(domain, private and public have been turned off same with my buddy who is no the same network). i am using an android phone's mobile hotspot to check this.
it would be great if someone could help me on this.
thanks in advance.
I asked something similar
I don't know how to do it purely on WSL. But on windows you have to start the "TCPSVCS.EXE" process. located on System32
I am trying to install OpenCPU inside a docker container. After some steps, this message appears:
I am quite new to Linux because I am a Windows user. I found nothing on my research so I am asking this question.
Can I just choose some random mail here? Thanks in advance.
I am working custom platform based on x86_64 running 3.10 kernel,
Recently I found an issue related to GARP. It seems like no GARP
packets are being sent out when an Interface is made up. But I also
noticed that only when I use "arping" tool only then it sends out any
GARP packet.
I also try setting the net variable "arp_notify" then I see the
arp_send() function is being called after that I am unable to track
further.
Could you please help me, what could be issue, Is it a valid
expectation that during interface up the linux kernel should send out
GARP packet? If so, am I missing any kernel configuration related to
it?
Thanks in Advance.
I am trying to implement wormhole attack in ns2 using aodv....I started project and i was not able to build the tunnel by using packet encapsulation.. I would like to know any one has implemented it using packet encapsulation.... I have looked around the internet for source code on this, but have found none. Does anyone know where to find source code for Wormhole sensor Attacks (for simulation purposes) or wormhole detection? any help on this issue is appreciated.
Looking forward for your help,
