Using Aircrack

aircrack-ng input.cap -J hashcat_output

Unfortunately the above command doesn’t seem to work anymore.

If you try to run Hashcat with the outputted file you’ll get an error.

hashcat_output.hccap: Old hccap format detected! You need to update: https://hashcat.net/q/hccapx

Using Hashcat utils

Refer to this guide for installing the Hashcat utils.

Basic syntax is

./cap2hccapx.bin input.cap output.hccapx

Example

~/Downloads/hashcat-utils-master/src/cap2hccapx.bin aircrack-01.cap aircrack.hccapx

Unity 2D C# Script to Spawn Object on Screen at Touch Position

Posted on by

You’ll need a touch screen to test this out.  Easiest way is to use the Unity Remote 5 app.  It allows you to use your Android device as a touch screen input.

Start by creating a new empty C# script named “TouchScript” and paste in the following code.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class TouchScript : MonoBehaviour {

public GameObject bullet;

void Start () {

}

void Update () {
Touch myTouch = Input.GetTouch (0);
for(int i =0; i < Input.touchCount; i++)
if (myTouch.phase == TouchPhase.Began) {
{
Debug.Log ("Touch Position" + myTouch.position);
SpawnBullet (myTouch);
}
}
}

void SpawnBullet(Touch fireTouch) {
Vector3 touchPos = Camera.main.ScreenToWorldPoint (fireTouch.position);
touchPos.z = 1; // Puts the z coordinates at 1 so it is visible to the camera.
Debug.Log("Vector3 Pos" + touchPos);
Instantiate (bullet, touchPos, Quaternion.identity);
}
}

Now you’ll need to put your script on a game object.  You should be able to drag and drop it on any game object, in this case the Main Camera “green”.

Next drag and drop the game object prefab to the script “red”.  This tells the script which game object to spawn or instantiate when you touch the screen.

Run the scene.  It should now create a game object where you touch on the screen.

 

 

Increase Disk Size of Linux VM in VMware

This is for extending a regular Ubuntu Linux partition, if you need to resize, expand a LVM partition refer to this guide.  I am using Gparted as I ran into some issues using parted for moving the partitions around.

Shut the VM down,

sudo shutdown -h now

It is a good idea to take a snapshot of the VM before resizing the disk, so if you run into an issue you have something to revert back to.  In the vSphere Client, right click on the VM -> Snapshot -> Take Snapshot.

Change VM Disk size by right clicking on the VM and going to Edit Settings

You can now boot up the VM.  Fire up GParted and it should show some unallocated space at the end of your drive.

Now in the next two images we are moving the Extended partition, which contains the Swap Partition to the end of the drive, so the unallocated space is adjacent to our root partition.

  1. Turn off the swap space by right clicking on the swap partition and hit Swapoff.
  2. Right click on the extended partition and extend to the the end of the Drive
  3. Right click on linux-swap and move to the end of drive.
  4. You should now have something similar to this

Hit Apply and write the changes to the disk then

  1. Right click on the extended partition and shrink to the end
  2. Right click on /dev/sda1 “Root partition” and extend to extended partition.

It should now look like this

Hit apply, then right click on the linux-swap and turn Swapon.

Enjoy the extra space.
