ARP for Dummy like Me!

ARP used to map IP address to MAC address on data link layer. It mainly used when Host is connected over Ethernet.

In long explanation,
This protocol used to locate address of a Host (Physical/Virtual) in network. The address is searched or "resolved" by sending an "information" to a server (other host). The server after received the information will then identify itself and respond back with the network information. The responded information contain the required address. This always happen over Ethernet.Ethernet address dependent to the hardware which is Network Interface card.So, during ARP request, it try to ask which IP associated with which MAC address.
If you have used wireshark, maybe you can remember on Info section, there are always message saying "Who has $IP". For example:

 Situation where ARP is used.
Someone with IP X.X.X.X try ping $IP = Y.Y.Y.Y. We assume, the source PC did not have the IP information from the Target PC.
So it will try to us…

Fixing Installation Problem in Kali Linux 2018.2 for VirtualBox and VMware Workstation. (gcc 7.3.0)

Hello All.

Previously I had migrated my testing machine into a new laptop.

Well, it is a refurbished laptop, Dell E7240. After finish installing Kali, I proceed to install VMware player. Unfortunately it does not running and keep asking for location of gcc 7.3.0.

After giving up, I tried installing VirtualBox. Surprisingly it also failed.

Both keep asking for location of gcc 7.3.0.

So the solution that I discover is by running "sudo apt install virtualbox-dkms".

After reboot, I just try to run the VMware again, it now able to run.

Note: The way I did is after installing the virtualbox-dkms, I uninstall both virtualbox and vmware, restart the OS (I use Kali 2018.2) and install vmware again. It works flawlessly.

Good Luck and Cheers!

VMware Workstation 14 Bridge Mode not Connected to Internet

Hello again friends and readers (don't know how many of you read my writings, but whateva)

I recently encountered a problem where everytime I tried to set my vm on pc to Bridge mode, it will always not connected to internet.

At first I thought it was the image problem, but after several time of deleting and installing VM, I realised that that is not my actual problem.

Then after several minutes of internet surfing, I found some other folks with similar problem with me, and there is actually solution for that.

In short, what you need to do are:
-- Be sure your vm is stopped.
--Run the VMWare Virtual Network Editor
(click start and search for Virtual Network Editor)
-- Run it as administrator (or click the button at the bottom of the screen that says, "change settings." VMNet0 will dislpay when running as administrator. Otherwise, it will not be visible)
-- Highlight VMNet0 and click on "Automatic Settings"
-- You will s…
