fail2ban

In an attempt to harden the security on my Pi, I have installed fail2ban. The instructions can be found here

Fail2ban allows a remote computer to be blocked from connecting if a threshold of failed login attempts is made.

I am currently investigating why I am getting an error with this

sudo systemctl status fail2ban.service

Minetest

I have now set up a Minetest server on a Raspberry Pi. This works and I am able to ssh in to the Pi and start remotely.

Minetest

I have also set up a 3.5” Pi screen, set the pi to auto login and display the IP address(s) of the Pi. I followed some of the instructions at [2],[3] to set up the screen but didn't need the sections for setting up the gui.

The next step is to set up a router so try and provide an internal network at the library for playing minetest. I followed so

  1. Minetest
  2. 3.5 Inch RPi Display Touch – XPT2046 (480x320) Guide – Raspberry Pi Forums part 1
  3. pi 3 – What have you done to make generic TFT touchscreen display work? – Raspberry Pi Stack Exchange part 2

Should be able to bring some of this to the STEM Group on Saturday and probably need help setting up the router to provide a simple LAN.

STEM Group 13th April 2024 Write Up

We had a quiet session today so we were busy getting two computers installed with Windows 8, and another dual booting Windows XP and Windows 8. This went really well, after installing the OS we installed some applications that we want to use during sessions.

stem 1 stem 2

We spent the latter ½ of the event trying to sort out Wi-Fi as one of the computers lost connection, we ended in the IT suits, using the e-machines as a Wi-Fi hotspot (bridge to library Wi-Fi) so the Lenovo could connect properly.

We really DO need a reliable solution for this.

The next Stem group event will take place on :

Date: Saturday, April 27th 2024 Time: 10:30am to 15:00 Location: Paignton Library and Information Centre Room: 13 & IT Learning Centre

What is planned?

  • Run through of Lego Robot presentation
  • Run through of model car presentation
    • This is so that we can ensure when we do the actual presentations we are able to.
