As this series is going to eventually get to looking at cybersecurity, it would be a good idea to learn about networking concepts. This video seems good at explaining some of this. In fact, it also covers firewalls, which I had planned for a later post.

• Networking basics (2020)

I have also added links to details of common network ports and their associated services.

What is:

• a switch
• router
• gateway
• subnet
• gateway
• firewall
• DMZ

Links

• virtual machine login link
• Common Network Ports

I spent some time on last night, setting up a mini web server on m Raspberry pi.

So running a http server on a Raspberry Pi.

For this project I am just using the python3-test-server package,

1. Install python3-test-server
2. Create a directory to hold some html files
3. Change to this directory
4. Create a very basic html file e.g index.html
5. run python3 -m http.server:7800 where 7800 is the port you want to use

In the browser go to ip:7800

What I have done here, however is

• Run the server on the pi,
• Connected via ssh to create the site files and run the server
• Edited the basic website on the pi via ssh, by running a text editor

• To copy other files directly from my main PC to the Pi i used

  • scp file.jpg pi@ip:path e.g
    • scp file.jpg pi@ip:/home/pi/html/

I have, gone a little further than this:

In order to share my free software video dvd (and other resources) with people I:-

• Uploaded files to the server
• Created a web link to the iso file
• Edited my router firewall so it would allow a connection to the pi

I then shared the appropriate IP address with a friend via irc so he could download the ISO file, and it worked really well.
