Setting Up For This Course

Local VM

Install two pieces of software:

• VirtualBox, which you can get from this download page.
• Vagrant, which you can get from this download page.

Use Git Bash
mkdir networking
cd networking
vagrant init ubuntu/trusty64
vagrant up
When it is complete, you can log into the Linux instance with vagrant ssh. .
I have install it before so for me

• cd G:/Udacity/ud256/from\ ping\ to\ http/networking
• remove files in networking
• vagrant up(need about 6 hours to download)
• When it is complete, you can log into the Linux instance with vagrant ssh.
• If you log out of the Linux instance or close the terminal, the next time you want to use it you only need to run cd networking and vagrant ssh.

Installing networking tools

• SSH into your Linux machine. Then take a moment to bring it up to date with any package updates: sudo apt-get update && sudo apt-get upgrade

Note:

W: Failed to fetch http://security.ubuntu.com/ubuntu/dists/trusty-security/main/source/Sources  Hash Sum mismatch

• You’ll be using several network utility programs in this course. Some of them may already be installed, but just to make sure, let’s install them all:

sudo apt-get install netcat-openbsd tcpdump traceroute mtr
