Kali Linux Screen Resolution

Kali Linux is an operating system that is - without any doubt - a very useful tool for everyone that is in the IT business. It contains tools to not only check the security of systems but also help examine  and troubleshooting network issues, application issues etc.

I've always used Microsoft Windows as my primary operating system and since Hyper-V is available out of the box the last few years, all my virtual machines are running on Hyper-V.

Installing Kali Linux 2 on a virtual machine is pretty straight forward, assign the .iso file to the virtual machine's drive, start it and follow the setup wizard.

The Hyper-V drivers are part of the operating system, but you have to enable them manually by editing the /etc/initramfs-tools/modules file and adding the following lines:

hv_vmbus
hv_storvsc
hv_blkvsc
hv_netvsc

After saving the file, execute the update-initramfs –u command for changes to take effect and reboot the virtual machine.

To verify that the drivers are loaded, use the lsmod | grep hv command. You should see a bunch of hyper-v drivers.

This however will not adjust your screen resolution in order for Virtual Machine Connection to display the virtual machine in full screen. You have to set the resolution manually by editing the /etc/default/grub file.

Open the file using your favorite text editor and locate the line starting with:
GRUB_CMDLINE_LINUX_DEFAULT= and replace the value with ”quiet splash video=hyperv_fb:1920×1080″ assuming that the resolution of your screen is 1920x1080 and update your GRUB configuration executing the update-grub command. 

Again, reboot in order for changes to be applied. Hopefully, the full screen on virtual machine connection will take exactly the space available on your screen.

Domain Controller Machine Password Reset

Image
On my lab environment, I've configured two Active Directory sites since most enterprises have offices in more that one places. My lab however is not running 24/7 and the domain controllers in the second site are rarely turned on in order to save resources. This leads to issues with the Active Directory replication such as the "The target principal name is incorrect" error when I execute:  repadmin /syncall /AdeP. To remedy the issue, we have to reset the machine password of the domain controller that has been offline. First off, we are going to stop and disable the Kerberos Key Distribution Center (kdc) service on the problematic domain controller, in our case DC4. There may be some tickets in the cache so we should also clear them using klist purge Now it's time to change the machine password of the domain controller using the command netdom resetpwd /s:dc3 /ud:lab\administrator /pd:* Replace the "lab\administrator" with an account on your

Configuring a Certificate on Exchange Receive Connector

Today's article is about configuring Exchange receive connectors with specific certificates. Out of the box, Exchange uses self signed certificates to provide TLS secured mail flow. This will definitely be an issue if you expose the SMTP protocol to client computers since they won't trust the certificate. In this article we are going to configure a certificate that was issued by a third part authority to the Client Frontend receive connector. We'll start with getting the thumbprint of the certificate using the Get-ExchangeCertificate cmdlet: [PS] C:\> Get-ExchangeCertificate Thumbprint                               Subject ----------                               ------- 241B864DC82C664FECBA18B8D54987AAFB65B4C2 CN=*.lab.com, ...

Running Multiple NGINX Ingress Controllers in AKS

Image
In some of the previous articles of this blog, we went through the process of installing NGINX as the Ingress Controller in AKS clusters. Either for applications that should be available directly from the public internet, or for applications that should only be accessed from networks considered internal. In the majority of the cases, however, and given that an AKS cluster is an environment that is designed to host multiple applications and provide economy at scale, additional ingress controllers may be required. In this post, we're going to go through the process of deploying an additional NGINX ingress controller that is going to be used for internal applications. The below diagram depicts the desired outcome: The Angular application is published via the public NGINX through the Azure Load Balancer that has been assigned a public IP. The .NET app is published by a different set of NGINX pods that are deployed in a different namespace and their ingress controller service is connect
