The fastest and easiest way to get started with Docker on Mac. The preferred choice for millions of developers that are building containerized apps. Docker Desktop is a tool for MacOS and Windows machines for the building and sharing of containerized applications and microservices. Access Docker Desktop and follow the guided onboarding to build your first containerized application in minutes.
This evening I have started some training on LinkedIn Learning about Docker. Docker is software that allows for software to be placed in virtual containers containing the software and all its dependencies. Unlike virtual machines which virtualise the hardware and contain an operating system, a container runs just above the host operating system. Docker containers are generally much smaller than virtual machines.
The Docker Desktop installation dmg for MacOS X can be found at:
A Docker account is needed to access the download file, at time of writing (November 2018) this account is free. With the dmg downloaded and opened we need to drag and drop Docker.app onto the Applications folder.
The copying takes a few moments, and as the application has been downloaded from a 3rd party (i.e. not Apple Store) website it gives a warning on first launch.
After choosing “open” Docker greets us with a welcome whale and then asks for elevation (it needs the MacOS account password).
With all that out of the way, Docker is installed and ready to run. Docker places a docker whale icon onto the Mac OS task bar and asks for the Docker account information, this is the same Docker account created to download Docker.
Docker provides an install guide for Docker on MacOS at:
https://docs.docker.com/docker-for-mac/install/
What Next?
With Docker installed and logged into your Docker account, we can open up Terminal and check that everything is working. At the terminal prompt type:
docker –version
And this should return the Docker version/build that is currently installed, in my case this is version 18.09.0 build 4d60b4.
As Docker is new to me, it is time for the standard “Hello World!” to see how it works.
At the terminal prompt type:
docker run hello-world
As Docker could not find the “hello-world” image locally (i.e. on my Mac) it contacts the Docker daemon which then searches the Docker Hub, finds the latest “hello-world” image, downloads it, then creates a container to run it in and outputs the “Hello from Docker!” message via the Docker client into the terminal session.
As the above screen shot indicates, Docker can be used to run an Ubuntu (Linux) BASH session via Mac OS Terminal, via the following command:
docker run -it ubuntu bash
The uname -ais a BASH command that outputs information about the machine, operating system and kernel.
Docker provides a “Getting Started” guide at:
Docker containers use commands in the following format:
docker container COMMAND
To see what can be run in a container visit https://hub.docker.com/explore/
I’m going to give Docker a whirl and see what I can do, hopefully I will follow up with a new blog post soon.
A freeware utility to spoof MAC address instantly
Version 6.0.7
Windows 10/8.1/8/7/Vista/XP/Server 2012 R2/Server 2012/Server 2008 R2/Server 2008/Server 2003/Server 2000
Technitium MAC Address Changer allows you to change (spoof) Media Access Control (MAC) Address of your Network Interface Card (NIC) instantly. It has a very simple user interface and provides ample information regarding each NIC in the machine. Every NIC has a MAC address hard coded in its circuit by the manufacturer. This hard coded MAC address is used by windows drivers to access Ethernet Network (LAN). This tool can set a new MAC address to your NIC, bypassing the original hard coded MAC address. Technitium MAC Address Changer is a must tool in every security professionals tool box.
Features
- Works on Windows 10, 8 & 7 for both 32-bit and 64-bit.
- Enhanced network configuration presets with IPv6 support allow you to quickly switch between network configurations.
- Allows complete configuration of any network adapter.
- Command line options with entire software functionality available. You can select a preset from specified preset file to apply directly.
- Update network card vendors list feature allows you to download latest vendor data (OUI) from IEEE.org.
How Does It Work?
This software just writes a value into the windows registry. When the Network Adapter Device is enabled, windows searches for the registry value 'NetworkAddress' in the key HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass{4D36E972-E325-11CE-BFC1- 08002bE10318}[ID of NIC e.g. 0001]. If a value is present, windows will use it as MAC address, if not, windows will use the hard coded manufacturer provided MAC address. Some Network Adapter drivers have this facility built-in. It can be found in the Advance settings tab in the Network Adapter's Device properties in Windows Device Manager.
How To Change MAC Address
- Starting MAC address changer will list all available network adapters.
- Select the adapter you want to change the MAC address. You will get the details of your selection below.
- In the Information tab, find the Change MAC Address frame. Enter new MAC address in the field and click Change Now! button. You may even click Random MAC Address button to fill up a randomly selected MAC address from the vendor list available.
- To restore the original MAC address of the network adapter, select the adapter, click Restore Original button in the Change MAC Address frame.
NOTE: This tool cannot change MAC address of Microsoft Network Bridge. Network Bridge will automatically use the original MAC address of the first NIC added into bridge with the first octet of MAC address set to 0x02.
