I had to do this recently for accessing the new server for kinedo.co.uk

1. open command prompt (cmd)
2. enter ssh-keygenand press enter
3. press enter to all settings. now your key is saved in the location specified on your local machine

The whole cmd screen for me looks like this

C:\Users\mike>ssh-keygen
Generating public/private ed25519 key pair.
Enter file in which to save the key (C:\Users\mike/.ssh/id_ed25519):
Created directory 'C:\\Users\\mike/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in C:\Users\mike/.ssh/id_ed25519
Your public key has been saved in C:\Users\mike/.ssh/id_ed25519.pub
The key fingerprint is:
SHA256:fYFTlz+BHdO7TnqNKpUST6n2O2DmTHBp/9UvWBHfTjQ mike@DESKTOP-UOMG8LF
The key's randomart image is:
+--[ED25519 256]--+

Within the folder there is now a 'PUB File' which you can share with others to authenticate your machine.

We need a new approach for adding CAPTCHA protection to forms on the websites.

I have replaced the plugin in \Shared joomla Software\111 - Essentials\reCaptcha for J5\ReCaptcha3_UNZIP\plg_recaptcha3

Install as you would any other plugin.

Disable the existing CAPTCHA Plugins

Get the reCAPTCHA Keys from:  https://console.cloud.google.com/security/recaptcha?hl=en&project=metagaap-map-api

Select the relevant website

In this instance I am using the Kinedo keys that extend over the installersaniflo.co.uk website.

Click Edit Key

Now you can see the websites that shre the key and the keys themselves

Copy the site Key and the Secret Key into the plugin

to protect the forms add the following code to the 'Element Selector' of the Plugin.  Where the plugin ID is the '3' numeral shown.

rsform_3_page_0

If there is more then one form then use the following syntax, where you have four forms with IDs 3,4,5 and 6

rsform_3_page_0,rsform_4_page_0,rsform_5_page_0,rsform_6_page_0

Sites that can give us useful information about the state of DNS

https://whatsmydns.com 

You can search by any DNS metric and see where the DNS is propogated round the globe

Preview a site on our server before DNS points the domain at us by editing the 'hosts' file on your local PC.

On your computer search for notepad, right click and run as administrator:
In notepad, file open:
C:\Windows\System32\drivers\etc
Change the file type to all files
Open hosts,

Enter the IP address of the server and the site you want to see. Save and close.
