UPGRADE PORTAINER COMMUNITY EDITION ON DOCKER / / RASPBERRY PI

Here is a quick how-to for the way I updated my portainer to the latest

SSH to the Raspberry Pi 5

login

sudo su –
docker stop portainer
docker rm portainer
docker pull portainer/portainer-ce:latest
docker run -d -p 8000:8000 -p 9443:9443 –name=portainer –restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce:latest

Open a browser, navigate to your Raspberry Pi 5:9443 and then login

Success!

CLEAR COMMAND HISTORY IN LINUX

It is common practice to simply type in commands into a terminal and leave the terminal with never clearing the history. The problem is, if someone accesses your system, they can see everything you have done, which can be an issue.

To check your terminal history, Open a Terminal and type:
history

To clear the History, simply type:
history -c

Now you can check your history again by typing:
history

And you can see it is clear. Do this before you log off your computer every time for good measure

ALFA DRIVER INSTALL FOR KALI 2202.1 ON RASPBERRY PI 4

Open a terminal

sudo apt-get update

sudo apt-get upgrade

ifconfig

Note your wireless adapters…if any are installed

lsusb

Note the USB devices on the pi. You will not see the ALFA wifi device

Next type

sudo apt-get install realtek-rtl88xxau-dkms

Drivers will install, this may take a few minutes.

Once it is done type the following

lsusb

You will now see the Realtek Adapter

ifconfig

You will now see your ALFA wireless card

SCRAPE DAILY SHORT DATA FROM FINRA

Here is a quick how-to on getting the daily short data. From this I look to see if the short volume has increased or decreased on a particular stock by leveraging a Power BI Dashboard that I had created. This guide is to show the simple command I run to initially scrape all the data

From a Linux box

Open a terminal

Type:
mkdir FINRA
cd FINRA
wget -r -np http://regsho.finra.org/regsho-Index.html

After it downloads the data I run
rm *.html

To remove the additional files that are not relevant, and then I move the data to where I need it

RASPBERRY PI 4 – OS VERSION

Quick, simple trick to see the Version of the Operating system that you are using

Open a terminal
from a terminal, type:
cat /etc/os-release

It will return something like this
NAME=”Ubuntu”
VERSION=”21.04 (Hirsute Hippo)”
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME=”Ubuntu 21.04″
VERSION_ID=”21.04″
HOME_URL=”https://www.ubuntu.com/”
SUPPORT_URL=”https://help.ubuntu.com/”
BUG_REPORT_URL=”https://bugs.launchpad.net/ubuntu/”
PRIVACY_POLICY_URL=”https://www.ubuntu.com/legal/terms-and-policies/privacy-policy”
VERSION_CODENAME=hirsute
UBUNTU_CODENAME=hirsute

As you can see, my version is Ubuntu 21.04

SCRAPING YAHOO FINANCE FOR ALL STOCK DATA

I found a great little snippet of code over on Kaggle,


and needed to build a system to run it from
https://tacticalware.com/jupyter-installation-on-a-headless-raspberry-pi-4-running-ubuntu-20-10/

Once you build the system as I did in my guide above you will need to do one other thing to get it to run
Open Putty
SSH to your Jupyter Pi
Login
Type:
sudo bash
pip instal yfinance

Now on another computer you can open your Jupyter notebook at
http://Jupyter:8888

Then go back to


Click File
Click Download
It will give you a file with the extension of ipynb

You can then go back to your Jupyter notebook and upload it

Once you upload it, run the notebook and it should scrape about 2.5GB of data, direct for your viewing pleasure

INSTALL MONGODB ON RASPBERRY PI 4

By far the best guide I have found, in starting this journey, was written by Mark Smith on https://developer.mongodb.com/how-to/mongodb-on-raspberry-pi/

If you want to see why things work the way they do, please visit his guide. My guide below is just the commands, and how I am connecting into the database once it is setup.

To begin, first you will want to install Ubuntu Server 20.10 as described here:
https://tacticalware.com/install-ubuntu-server-20-10-64-bit-on-raspberry-pi-4-using-a-m-2-drive/

Once you are up and running, ssh into the Raspberry Pi
Login

From the terminal run the following:
sudo bash

wget -qO – https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add –

echo “deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/4.4 multiverse” | tee /etc/apt/sources.list.d/mongodb-org-4.4.list

apt-get update

apt-get install -y mongodb-org

systemctl daemon-reload

systemctl enable mongod

systemctl start mongod

systemctl status mongod

CTRL button +c to exit

mongo
use admin

db.createUser( { user: "admin",
 
        pwd: "SuperSecretPassword",

        roles: [ "userAdminAnyDatabase",

                 "dbAdminAnyDatabase",

                 "readWriteAnyDatabase"] } )

exit

nano /etc/mongod.conf

Add these lines to the end of the file

security:

   authorization: enabled

CTRL +x to Exit
Y to Save

systemctl restart mongod

mongo

db.adminCommand({listDatabases: 1})

Make sure you had no errors

exit

mongo -u “admin” -p

Enter your admin password for mongo, aks your SuperSecretPassword

Type
db.adminCommand({listDatabases: 1})
This will list out your databases and ensure you created it properly

exit

nano /etc/mongod.conf
and Change the bind ip from 127.0.0.1 to 0.0.0.0

net:
   port: 27017
   bindIp: 0.0.0.0

CTRL +x to Exit
Y to Save

systemctl restart mongod

ufw allow 27017/tcp

MongoDB is now successfully setup and running. On to configuring the Windows 10 system

To connect to the MongoDB from a Windows 10 computer

Open an Internet Browser on your Windows 10 computer
Navigate to https://robomongo.org/
Download the Robomongo Robo 3T Client
Once you install it, add these settings to connect to your system
Click Create
Connection Tab
Type – Direct Connection
Address – The IP of your Raspberry Pi
Port 27017
Authentication Tab
Check mark Perform Authentication
Database is admin
User Name is admin
Password is your SuperSecretPassword
Auth is SCRAM
Click Save
Click Connect

You are now connected and ready to run with your MongoDB environment

RASPBERRY PI RDP TO WINDOWS 10

From time to time I need the ability to use RDP from my Raspberry Pi, to connect to my Windows 10 computer. Here is how I have installed RDP on my Raspberry Pi.

First you need to make sure your Raspberry Pi is running on Raspbian

Next, open a Terminal
Type:
sudo bash
apt-get update
apt-get dist-upgrade
apt-get install xrdp remmina
Press Y when prompted
The software will install
Once it has completed, reboot your Raspberry Pi

When you are back onto your Desktop
Go to the Raspberry Menu in the top left
Select Internet
Click Remmina

Now put the settings of your Windows 10 computer in, and make sure your Windows 10 system already has RDP enabled

Connect, and you are in!
