QUESTION
I am sending a command to a power supply device over TCP Ethernet using netcat (nc) on Linux Ubuntu 18.04 and 20.04. If I use echo the device fails to properly receive the command, but if I use printf it works fine. Why?
ANSWER
Answered 2021-Nov-17 at 18:46Ugh! Found it.
Ensure you're not accidentally sending a newline char (\n) at the end of the command
It looks like echo adds a trailing newline to the string, whereas printf does NOT, and this trailing newline character is interfering with the device's ability to parse the command. If I forcefully add it (a newline char, \n) to the end of the printf cmd, then it fails too--meaning the device will not respond to the command as expected:
QUESTION
I have developed a PHP based application. This application runs actually in Kubernetes and mainly using minikube on my machine. I am using PhpStorm as IDE and I also use Xdebug for debugging purposes.
What I know from my researches are that when you start PhpStorm with Xdebug, it will start listening on a port (9000 by default). When I connect to my container (in minikube), I am able to reach the IDE at the port 9000 with netcat :
...ANSWER
Answered 2021-Dec-15 at 09:29If you try to debug a script with xdebug_info() in it, it will tell you exactly what Xdebug tried to do, if anything at all.
You can also make a log file by setting xdebug.log=/tmp/xdebug.log and xdebug.log_level=10, and then this log file will show even greater detail as to what went on.
Please note that although a connection can be open, you might not have the right process. Port 9000 is also used by PHP-FPM, which is why Xdebug 3 now uses 9003 by default.

Could you explain the "weird" behaviour? I'm running netcat on Linux, as a UDP echo server:
...ANSWER
Answered 2022-Feb-16 at 12:24This is a ncat limitation.
Let's use strace to look into what ncat is up to. Conveniently, strace has -e option to filter system calls, e.g. -e %net for logging network-related syscalls. Let's start the server first:
QUESTION
for a university project I am testing the log4j vulnerability. To do this, I use a python server that connects to the java client by creating a reverse shell. Everything works except the output to server which is not displayed correctly. Specifically, the server shows the output of two previous inputs and I'm not understanding why. I'm new to python and java programming so I'm a little confused.
Initial project: https://github.com/KleekEthicalHacking/log4j-exploit I made some changes and added a python socket to handle the reverse shell.
PS: with netcat it seems to work fine but command with some space non work (ex: cd .. not work)
For run this project i use kali linux (python server) and ubuntu (java webapp). This code does not yet manage clients with windows os

QUESTION
Do I still need to expose pod via clusterip service?
There are 3 pods - main, front, api. I need to allow ingress+egress connection to main pod only from the pods- api and frontend. I also created service-main - service that exposes main pod on port:80.
I don't know how to test it, tried:
...ANSWER
Answered 2022-Jan-26 at 15:29Network policies and services are two different and independent Kubernetes resources.
An abstract way to expose an application running on a set of Pods as a network service.
Good explanation from the Kubernetes docs:
Kubernetes Pods are created and destroyed to match the state of your cluster. Pods are nonpermanent resources. If you use a Deployment to run your app, it can create and destroy Pods dynamically.
Each Pod gets its own IP address, however in a Deployment, the set of Pods running in one moment in time could be different from the set of Pods running that application a moment later.
This leads to a problem: if some set of Pods (call them "backends") provides functionality to other Pods (call them "frontends") inside your cluster, how do the frontends find out and keep track of which IP address to connect to, so that the frontend can use the backend part of the workload?
Enter Services.
Also another good explanation in this answer.
For production you should use a workload resources instead of creating pods directly:
Pods are generally not created directly and are created using workload resources. See Working with Pods for more information on how Pods are used with workload resources. Here are some examples of workload resources that manage one or more Pods:
And use services to make requests to your application.
Network policies are used to control traffic flow:
If you want to control traffic flow at the IP address or port level (OSI layer 3 or 4), then you might consider using Kubernetes NetworkPolicies for particular applications in your cluster.
Network policies target pods, not services (an abstraction). Check this answer and this one.
Regarding your examples - your network policy is correct (as I tested it below). The problem is that your cluster may not be compatible:
For Network Policies to take effect, your cluster needs to run a network plugin which also enforces them. Project Calico or Cilium are plugins that do so. This is not the default when creating a cluster!
Test on kubeadm cluster with Calico plugin -> I created similar pods as you did, but I changed container part:

QUESTION
I am trying to send en email with Mailkit and locally(windows) it is working fine but on the server(ubuntu 20.04) it is not.
I opend the port 465 using ufw(firewall) but it is still not working. I get an Timout* when calling
...ANSWER
Answered 2021-Nov-29 at 16:39Netcat works on your Windows machine for the same reason that MailKit works on your Windows machine.
Your Windows machine has an unblock route to the mail server.
Your Ubuntu server, on the other hand, does not have an unblocked route to the mail server, so it fails to connect there.
You need to figure out your firewall and/or routing tables on your Ubuntu server and fix that to allow connecting to the mail server.
