SCCM Prerequisite check error when upgradeing – SQL Server Configuration for site upgrade failed

I had a opportunity to upgrade SCCM to new version from 2006 ver. As some of you may know that before SCCM upgrade there is a process to check whether current environment meet per-requisites. I new that my SQL environment and server environment meet standard after reviewing Microsoft documents. But my environment was keep failing per-requisites no matter which new version I choose. After several ours of browsing and reading through logs was able to locate the issue on SQL and pass through the obstacle and successfully upgrade the environment.

All I had to do is connect with SQL server and run two command. I’m no expert on SQL so I’m going simply put here two command that you need to run in your SQL server environment. I’ll also will put link here for great post related to SCCM upgrade.

There are many issues that can generate above mentioned error while imaging using SCCM. But the biggest hurdle is locating the scope ID. Because usually it gives you some giant number not that clear.

How to setup Tor Bridge

I am not going to detail what is tor and all. Because if you already looking to setup Tor bridge, I assume that you already know about tor 😊. You can learn more about tor here anyways

In my setup I’ve used Lubuntu ( Focal distribution) ( ) light weight ubuntu base distro on spare old NUC box. This setup needs very little resources since Lubuntu design to run on your old hardware. Also, system can run 24/7 with very little power consumption.

First you need to get install latest tor. Because Debain LTS ver does not always give you the latest stable tor. if your tor bridge not safe, your intended user will not be safe either.

***** Enable package manager

# apt install apt-transport-https

***** Next go the to /etc/apt/sources.list or a new file in /etc/apt/sources.list.d/ add below entries,

   deb <DISTRIBUTION> main

   deb-src <DISTRIBUTION> main

in my case it was little different because Focal dropped 32-bit support,

   deb     [arch=amd64] focal main

   deb-src [arch=amd64] focal main

***** You can fine your distro ver by running lsb_release -c in terminal.

***** Then add gpg Keys to sign packages

# wget -qO- | gpg --import

# gpg --export A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89 | apt-key add –

***** Install Key rings

# apt update

# apt install tor

Get more info here

****** Install Tor and proxy packages

# apt-get  install tor

# apt-get install obfs4proxy

# apt-get update

***** Brows into /etc/tor/  and right click and edit as admin torrc file or open with terminal editor,

Comment out or add these lines if the do not exists,

BridgeRelay 1

ORPort TODO1 = In my case TODO1 replace with 9001

ServerTransportListenAddr obfs4 = I changed TODO2 to 9002

ExtORPort auto

ContactInfo = change out your address you want to be contact if the relay have issue

Nickname PickANickname = set a nickname whatever you like

ServerTransportPlugin obfs4 exec /usr/bin/obfs4proxy

Log notice file /var/log/tor/notices.log

****** Set NoNewPrivileges=no in these two files,



After that run below in terminal,

# systemctl daemon-reload

# systemctl restart tor

***** Now you need to port forward above set ports, so that Tor can reach your bridge.

An installation step failed. Kali Linux Install Error

I’ve recently face an error with Kali Linux install in VMware Player and even after giving ample enough space /resources it was keep falling with install step failed and I’ve confirm that VM installer has internet access.

This is pretty much loop back even after restart the install. I’ve tried many times and different methods to install and come back to screen saying hit continue and it will bring up menu that you can skip the step of installing software, pretty much you will loose the GUI and all Kali packages.

After few hours browsing and cursing this the method I used to get kali install and functioning.

**** Basically hit continue and once you come to next step where you have option to skip,skip the step and installer will continue but when kali boot back you will be presented with basic debain shell.

****Log into the shell with your username and password then run these in a order and reboot. Make sure that your Kali can reach to the internet.

This command will install GUI XFACE, after install you will be able to log into Kali GUI.

***sudo apt-get install kali-desktop-xfce

Then you need to update kali install,

***sudo apt update

After this kali need to download base tool set via meta package install. This step will install base Kali tool and some other top tools. You can refer to this link for Kali meta packages in detail

*** sudo apt update && sudo apt install kali-linux

*** sudo apt update && sudo apt install kali-linux-full

Here is a great blog post to install meta packages
