PeopleCert has recently announced that all its Global Best Practice certifications (also Foundation levels), including the most popular ones such as ITIL and PRINCE2, will have to be renewed.

If you were certified before 30 June 2020: You will have until 1 July 2023 to choose to renew your certification(s), regardless of your original award date.
If you were certified after June 2020: You will have the option to renew your certification(s) within 3 years of the original award date.

There are several ways to renew the certification

1. Retake the same exam: You can choose to renew your certification by re-taking your original exam before the renewal date.
2. Take further courses and certifications: You can choose to renew your certification by attending another course and taking an exam within the same product suite before the renewal date.
3. From March 2023, a third renewal path will be available: You will be able to choose to renew your certification through collecting and logging CPD points. More details on this path will follow soon.

After you created a docker instance, by default it will sharing the docker host default network interface IP address and port.

If you want to create a virtual LAN for docker and getting static dedicated IP address from the same network as the host, you will need to setup a MacVLAN under the docker.

Simply use the below command to create a MacVLAN. But first, you will need to identify your host network interface, IP range, subnet and the DHCP configuration to avoid IP conflict.

sudo docker network create -d macvlan -o -parent=eth0 --subnet=192.168.81.0/24 --gateway=192.168.81.1 --ip-range=192.168.81.8/32 new-macvlan

The next step is to create a bridge interface on the docker, you use any network which is not in use.

Finally, add both bridge network and macvlan network to the docker instance to get it work.

PSTools is a set of collection of similar tools allow you to manage remote systems as well as the local one. The tool can execute with powershell and schedule tasks to let you perform a lot of remote tasks and troubleshooting.

Here is an example for psping.exe in PStools, not only to measure network performance but also to check the health of the website. We can simply write a BAT script to create the ping result log with timestamp.

echo %date%
SET mm=%date:~4,2%
SET dd=%date:~7,2%
SET yy=%date:~12,2%
echo %time%
SET hh=%time:~0,2%
SET min=%time:~3,2%
SET ss=%time:~6,2%
"C:\temp\psping.exe" xxx.com:443 >> "C:\temp\log\logfile_%mm%%dd%%yy%_%hh%%min%%ss%.log"

The new laptop nowadays usually don’t come with LAN ports, you may had an issue when trying to image multiple laptops with same USB to Ethernet Adapter.

Beginning with SCCM 1610, you can provide a list of hardware IDs that SCCM will ignore when using PXE boot and client registration. You can now exclude the MAC address and SMBIOS GUID in the console so that same adapters can easily be reused.

1. In the SCCM console, go to Administration / Site Configuration / Sites
2. On the top ribbon, click Hierarchy Settings
3. In the Client Approval and Conflicting Records tab
4. In the Duplicate hardware identifiers section, click Add and enter your MAC Address or SMBIOS GUID to exclude

If for any reason you want to block visitors from any country, the solution is extremely simple!

First, enable the IP Geolocation in CloudFlare

And then everything can be done from .htaccess file, via apache server:

# Block countries - IP Geolocation
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP:CF-IPCountry} ^(CN|IR|PK|TH|BD)$
RewriteRule ^ - [F,L]
</IfModule>

The country code list can be find from the below link:
