QUESTION
I've installed an npm package on a Pi that uses mscdex/cap (cap) to sniff packets for both udp and tcp on specific ports over wlan0. Cap defaults to promiscuous mode and I want to view packets being sent to another computer on the same wireless subnet. So, how can I listen to packets sent to a port on another computer/IP address within the same wifi subnet?
...ANSWER
Answered 2021-Mar-10 at 23:14npm cap (github.com/mscdex/cap) uses libpcap/npcap to capture packets, so you should be able to capture wireless traffic. However, in order to capture wireless traffic, you need to specify the correct interface (something like wlan0, and will depend on your machine).
Based on the documentation for this project, the only link-layer protocol it is designed to parse is ethernet, not 802.11.

I have a GKE v1.17.400 private cluster running with NAT gateway. On the cluster I have multiple application that use google services such as stackdriver, pubsub and cloud sql.
My applications are running on .net-core 2.2. It subscribing and publishing to a Pub/Sub topic.
When having high load I am experiencing issues of connectivity with Google Cloud services.
This issues cause many different logs such as:

Answered 2021-Feb-02 at 09:58We have discovered that the issue occurred because of we were using c# built-in ManualResetEvent from an async code. Seems like it caused some sort of a deadlock for the application threads.
Using SemaphoreSlim instead fixed the issue.
QUESTION
I have a problem where I have a Kubernetes cluster with two worker nodes, and one master. Let's lab them W1, W2, and M. I have a deployment that creates a set of CentOS7 pods, some on each worker. I use Multus so that there is an extra net1 interface on each pod that is mapped to eth1 on the workers. All the pods have net1 connected to the same macvlan named ‘up-net’.
On both W1 and W2 I can ping between pods that run on the same node, but a pod in W1 can't ping another one in W2 and vise-versa. Pinging over the standard kube network on eth0 works in all cases. It’s just the macvlan that has this problem.
That's the problem in short. So let me now describe the setup we're using in more detail.
We have a lab with 3 physical servers, on which we've deployed Kolla (which is Openstack installed on Kubernets). In this Openstack installation, I'm again trying to set up a Kubernetes installation were the master and worker nodes are hosted in Openstack virtual machines (i.e. W1, W2, M) are VM's running in Openstack. This means that we have three layers of virtualization in total. Just wanted to mention it should anyone know any potential leads based on that. But I haven’t bumped into any problem I think is related to the virtualization. Can also mention that these vm's have two interfaces eth0, and eth1. Eth1 is the device I want the macvlan on. Lastly, for both vm's and physical servers the operating system is CentOS7.
About the Kubernetes installation:
- The Kubernetes (overcloud) was installed using Kubespray.
- I edited the host files to make node1 master node2 W1 and node3 W2.
- I set kube_network_plugin_multus to true to.
- Whereabouts is used to assign ip addresses to the net1 interfaces.
- I use calico as the networking driver.
Here’s the configurations used for the macvlan network:

Answered 2021-Feb-01 at 07:41To conclude I've managed to find the answer myself. It turned out it was the OpenStack security group that caused the problem. All I needed to change to get things running was to disable port security on all of the eth1-network ports. This is the command I used for every such port:

I am trying to use pcap4j to get TcpPackets from loopback address. I can read packets successfully but I cannot convert them to TcpPackets:
...ANSWER
Answered 2020-Oct-30 at 13:22The pcap4j repository contains an example of how to deal with fragmented packets:
https://github.com/kaitoy/pcap4j/blob/v1/pcap4j-sample/src/main/java/org/pcap4j/sample/DefragmentEcho.java
Basically you need to group the IpV4Packets based on their header.identification
QUESTION
I am new to DPDK, currently testing IP reassemble API and I am having difficulties. Below is the C++ code which I wrote to test the IP reassemble. I took the reference from the examples list provided from dpdk itself. dpdk version which I am using is 20.08 in debian machine. dpdk user guide mentions the API works on src add, dst add and packet ID, even though all three data are proper still the API returns NULL. Any kind of help will be much appreciated. Thanks in advance.
...ANSWER
Answered 2020-Oct-22 at 09:27DPDK API rte_ipv4_frag_reassemble_packet returns NULL in 2 ocassion
- an error occurred
- not all fragments of the packet are collected yet
Based on the code and logs shared it looks like you are
- sending the last fragment multiple times.
- setting time out as
cur_tsc
Note:
- the easiest way to test your packet is run it against
ip_reassemblyexample and cross check the variance. if (mo == NULL)it only means not sufficient fragments are received.
[edit-1] Hence I request to model your code as dpdk example ip_reassembly since assuming rte_ipv4_frag_reassemble_packet returning NULL is not always a failure.
[edit-2] cleaning up the code and adding missing libraries I am able to get this working with right set of fragment packets

I want two NodeMCU ESP8266s to communicate to each other, but I don't want them in a network. I was thinking about the transmitter could broadcast packets all the time and the reciever could use the promiscuous mode to capture and read the packets. How to do this?
EDIT: If this is not possible using the ESP8266 is there a chip which could do this(maybe a Raspberry PI and a NodeMCU or something).
...ANSWER
Answered 2020-Aug-24 at 12:33ESP is a Wi-Fi device. Wi-Fi needs a network in order to establish link-level connectivity.
But you can easily create an ad-hoc network between two nodes: start one in AP mode and another in client mode, connecting to that AP.
For example:

I use a Ubuntu Linux Machine and promiscuous mode is on in my WiFi NIC.
These are the IP in my network

I want to capture the packets that are transmitted through My windows machine and the WiFi router.
This is the output of ifconfig
...ANSWER
Answered 2020-Aug-03 at 12:20I don't think what you ask for is possible. If the WiFi connection is protected then at most what you'll see are random (encrypted) bytes in the air. And even for that you will probably need to set your driver to Monitor Mode.

Install promiscuous
On a UNIX-like operating system, using your system’s package manager is easiest. However, the packaged Ruby version may not be the newest one. There is also an installer for Windows. Managers help you to switch between multiple Ruby versions on your system. Installers can be used to install a specific or multiple Ruby versions. Please refer ruby-lang.org for more information.
