Reset Your Forgotten Ubuntu Password in 2 Minutes or Less





If you’ve ever forgotten your password, you aren’t alone… it’s probably one of the most common tech support problems I’ve encountered over the years. Luckily if you are using Ubuntu they made it incredibly easy to reset your password.
image
All it takes is adjusting the boot parameters slightly and typing a command or two, but we’ll walk you through it.
Reset Your Ubuntu Password
Reboot your computer, and then as soon as you see the GRUB Loading screen, make sure to hit the ESC key so that you can get to the menu.
image
Root Shell – Easy Method
If you have the option, you can choose the “recovery mode” item on the menu, usually found right below your default kernel option.
image[3]
Then choose “Drop to root shell prompt” from this menu.
image[6]
This should give you a root shell prompt.
Alternate Root Shell Method
If you don’t have the recovery mode option, this is the alternate way to manually edit the grub options to allow for a root shell.
First you’ll want to make sure to choose the regular boot kernel that you use (typically just the default one), and then use the “e” key to choose to edit that boot option.
image
Now just hit the down arrow key over to the “kernel” option, and then use the “e” key to switch to edit mode for the kernel option.
image
You’ll first be presented with a screen that looks very similar to this one:
image
You’ll want to remove the “ro quiet splash” part with the backspace key, and then add this onto the end:
rw init=/bin/bash
image
Once you hit enter after adjusting the kernel line, you’ll need to use the B key to choose to boot with that option.
image
At this point the system should boot up very quickly to a command prompt.
Changing the Actual Password
You can use the following command to reset your password:
passwd <username>
For example my username being geek I used this command:
passwd geek
image
After changing your password, use the following commands to reboot your system. (The sync command makes sure to write out data to the disk before rebooting)
sync
reboot –f
I found that the –f parameter was necessary to get the reboot command to work for some reason. You could always hardware reset instead, but make sure to use the sync command first.
And now you should be able to login without any issues.

Error Faced while using KataCoda while Building Multiple dockers



Today I was doing some online training - Building and testing Multiple Dockers using Katacoda online platform. Ups, I guess I have not explained what Katacoda is ... Ok here is ....

Extracted from Wikipedia:  What is Katacoda ?? 
"A code kata is an exercise in programming which helps a programmer hone their skills through practice and repetition. The term was probably first coined by Dave Thomas, co-author of the book The Pragmatic Programmer,[1] in a bow to the Japanese concept of kata in the martial arts. As of October 2011, Dave Thomas has published 21 different katas.[2] "

While practicing some of the tasks in there I have notice docker build failing to build .. Did not resolved myself yet.. I guess I just wen to do a quick investigation and find out what was fundamentally causing the error.

Here is the errors I was getting;
















Basically for some reason, I was getting a weird error while building the Go layer ..
So, looking into the dashboard and what I was seeing then, I then realised that the error was on the command to install the Go on the docker .. Did not actually resolved it .. I guess, I just keep a record of it in case of happen again ..


So, as you can see there is a bug on there .. I need to investigate, later on I will publish, what I found out.. My intention is to replicate the build locate and see if I can spot the same error ..

How to Create You Lab on Kali Linux - Using VMware or VBox

Before you start - Here are something that you need to consider..

  • Install VirtualBox or Vmware
  • Install LiveCD in VirtualBox or Vmware
  • Boot and try out your LiveCD

Introduction.


There are lots of tutorials available on the internet related to hacking but the big problem lies in testing your theoretical skills. Unless you don't have practical exposure to hacking, you cannot really understand the strength of it. The technique I will discuss here will be advantageous for those who have only single system and want to set up a testing network using it. In case you have multiple systems then you can easily test for your skills by making one system as target and other as attacker.
VMware Workstation 12 Pro - Leading Edge PC Virtualization VMware Workstation 12 Pro


Download VMware Workstation or Player

The best way to practice hacking is within a virtual environment. Essentially, you set up a hacking system, such as Kali Linux, and some victims to exploit. Ideally, you would want multiple operating systems (Windows XP, Vista, 7, and 8, as well as a Linux flavor) and applications so that you can try out a variety of hacks.

Virtual machines and a virtual network are the best and safest way to set up a hacking lab. There are several virtualization systems out there, including Citrix, Oracle's VirtualBox, KVM, Microsoft's Virtual PC and Hyper-V, and VMware'sWorkstation, VMware Player and ESXi. For a laboratory environment, I strongly recommend VMware's Workstation or Player. Workstation is commercial product that costs under $200, while Player is free. You can also get a free 30-day trial of Workstation.

Player is limited to just playing VMs , while Workstation can both create and play VMs. Let's download VMware's Workstation or Player here.


Then - For you Images you can download a pre-built image. As it will allow you to save some time, you don't need to build the image from scratch. Here is a link for you to download several Linux pre-built Linux Images on SourceForge.

I don't encourage you to download pre-built Windows VM from anywhere, for the single fact that Microsoft itself provides you with pre-built Windows VM for you to use on your VM Lab. Again I did the research for you and here it the link for you to download the Windows of your choice,  Obs: Remember Windows only allow you to use those VM images for 30 days. Please, READ Microsoft TERMS AND CONDITIONS before you use their software here is the url for you.
