Cryptocurrencies have been back on the popular agenda lately, thanks mostly to the surging value of Bitcoin. I have been interested, but not massively invested in cryptocurrency for many years. If I had the courage to buy and hold all those years ago, I might be writing to you from a beach – I assure you, this is not the case! I have been getting into InfluxDB lately and its fantastic ability to store heaps of time series data. Well, using python and Coinbase, I am going to show you how to collect bitcoin (and other crypto assets) price data and store it in InfluxDB… then we are going to make some neat panels in Grafana to help us realise our data. This is going to be a longer write up than most, so here is here are links to each section: ...

A quick GitHub gist for anyone looking to write to an InfluxDB server with Python3. This is a generic function that accepts three inputs; as an example, I am using temperature data in degrees Celsius. Turning DHT11 readings into beautiful graphs in Grafana Once you have your data in influxDB, a great way to visualise it is using Grafana. I hope to bring you more posts in the future about visualising your python data with Grafana. ...

Following on from a previous post on how to setup a VLAN on a Fortigate hardware switch, this post is going to explain how we can link an AP-bridge SSID to a hardware switch and VLAN. For the most part, the only reference material you will need to complete this configuration can be found here: https://docs.fortinet.com/document/fortiap/6.4.0/fortiwifi-and-fortiap-cookbook/252439/configuring-the-fortigate-interface-to-manage-fortiap-units. However, if you have been working with Fortigates and by extension FortiOS for quite some time, you may be wonder where the CAPWAP option vanished to? Fortinet adopted this into the security fabric naming convention. CAPWAP has even been replaced in the CLI by ‘fabric’. ...

In this post, we are going to discuss how to add a VLAN to a hardware (sometimes referred to as physical) switch or interface on a Fortigate. It is worth noting that I actually do my testing on a FortiWifi, so I can assure you that this also applies there too. I will be focusing on the configuration which is relevant to FortiOS v6.0 and above, so your millage vary between versions. However, you need can usually be found over at the Fortinet Handbook: https://docs.fortinet.com/product/fortigate/6.0. ...

I have covered this a number of times in the past and the posts have proved popular and useful to many. So, here is my guide for updating to the latest version of Python 3 (3.9) on Debian 10 Buster. To clarify the purpose of this guide, Debian 10 ships with Python 2 (2.7) and Python 3 (3.7) installed at my time of writing. For those wishing to upgrade from python 3.7.X to 3.8.X or 3.9.X, this is the guide for you. If you are trying to configure python 3.7 as your default interpreter when you call ‘python‘, try this: CHANGING THE DEFAULT PYTHON VERSION IN DEBIAN. This method involves using the ‘update-alternatives‘ command. We will be using a similar method in this guide, however this time we only do so to give 3.9.X a higher priority to 3.7.X, rather than uninstalling older versions. ...
