A new monitor for my RISC OS and Mac systems

The Iconbar - Fri, 06/08/2018 - 07:53
Recently I decided to upgrade my monitors. I have a MacBook Pro laptop and I have 2 monitors - one at work which runs my laptop (replacing a 27 inch 10 year old Apple work monitor) and one for home also hosts my RaspberryPi and Titanium. I wanted a high resolution (3840 x 2160 for work) monitor which would also play nicely with my other machines.

The latest Macs use Apple's USB-C connections. You can buy adapters for connecting in other types of connector such as HDMI or you can now buy monitors which have a USB-C connector. Apple offers an LG monitor which provides 5K and can also power the computer and handle the display on a single cable. If money is no object, you want an uncluttered desk and a 'to die for' screen quality on the latest Macs, the LG UltraFine 5K Display is the current top option.

Not only is this monitor very expensive but it will not work on my RISC OS kit as it only has a USB-C input.... One monitor which has also had a lot of very favourable press coverage is another LG model (27UD88-W). This is much more affordable (under 500 pounds), has USB-C input (not powerful enough to act as a power supply as well but fine to drive a 4K display), and also allows for HDMI and DP-IN as well. There are even a couple of old style USB ports for good measure. So how well does this model work for all the machines?

Very well is the short answer. The screen quality is great and you can have all the machines power up and then switch between them. The 27UD88-W has a single joystick type control under the screen and (IMHO) this is one of the nicest switches I have used on monitors - 2 clicks and I am on a different screen. The screen is ultra-sharp on both the Mac and the lower resolution Titanium 1920 x 1200 display.

One word of caution on moving up to a higher resolution screen. My combined switch box (which allows me to share screen and keyboard/mouse through one switch box) does not work on the higher resolution screens. So if you are using a switch box, you may want to verify what it can support.

A really nice feature of the higher resolution screen is that you have your other machines accessible via VNC. This also gives you some idea of the extra 'real estate' the monitors can give you if you are working on a Mac.

If you are looking for a godo quality monitor to provide a high resolution display, which also plays well with your RISC OS kit, the LG 27UD88-W should be one of your shortlist.

DHCP – Activate Filter “Allow” & import MAC address from SCCM by WMI request - Tue, 08/29/2017 - 12:08

Hello folks,
Recently, i have post a script to interroge SCCM and find the MAC address informations. In this post, i show you how activate DHCP Filter “Allow” to protect your DHCP delivery lease to deny access to your network (i know, there is NAP or NAC but, it is a simple way to block the issuance of a DHCP lease).


First, you need to create a Active Directory user and give to this account rights “DHCP Administrator”.

In SCCM console, add this users to group “Read-only Analyst” .

Activate filter “Allow” on DHCP server

Connect to your DHCP Server and open the management consoleOn the IPV4 tab, open the drop-down menu, and then select the “Filters” option and right-click the “Allow” folder and select “Enable”.

From now, the DHCP server no longer delivers leases.

On the DHCP Server, launch this script for retreive and add the MAC Address informations from SCCM Server to filter list “Allow”.

Source code   # Connection information $SiteName = "FR1" $ServerSite = "sccm" # WMI Request $ImportSCCM = $(Get-WmiObject -Class SMS_R_SYSTEM -Namespace "root\sms\site_$SiteName" -computerName $ServerSite) # Create collection $Mycoll = @() foreach ($obj in $ImportSCCM) { Write-Host $obj.NetbiosName $obj.MACAddresses $obj.OperatingSystemNameandVersion $Mydetails = "" | Select-Object PCName, MacAddress, OS If ($([String]$obj.MACAddresses) -eq "") { $Mydetails.PCName = $obj.NetbiosName $Mydetails.MacAddress = "Nul" $Mydetails.OS = $obj.OperatingSystemNameandVersion } Else { $Mydetails.PCName = $obj.NetbiosName $Mydetails.MacAddress = [String]$obj.MACAddresses -replace ":","-" $Mydetails.OS = $obj.OperatingSystemNameandVersion } $Mycoll += $Mydetails } #Add MacAddress into DHCP Filter foreach ($objects in $Mycoll) { Add-DhcpServerv4Filter -List Allow -MacAddress $objects.MacAddress -Description $objects.PCName -Confirm:$false -Force -Verbose } # Remove Obsolete entries Compare-Object $(($Mycoll | Select-Object MacAddress).MacAddress) $(Get-DhcpServerv4Filter -ComputerName $DHCPServer -List Allow | Select-Object MacAddress).MacAddress -IncludeEqual | % { if ($_.SideIndicator -eq "=>") { Remove-DhcpServerv4Filter -ComputerName $DHCPServer -MacAddress $_.InputObject -Confirm:$false -Verbose } }

When the script is finished, you can see into the management console of DHCP Server, the entries are add into the “Allow” list.

The DHCP server correctly delivers the lease of the device whose MAC Address is allowed.

SCCM – Find Devices MAC Address - Fri, 08/25/2017 - 12:56

Hello Folks,

This week I needed to export from SCCM, the devices name and MAC Address to a CSV file.

I need this file to create green list into DHCP server. The Green list give permission to have a lease from DHCP server. I will speak of this subject in a futur post.

To find informations on devices into SCCM, we can work with WMI Class of SCCM. This script is based on WMI request.

Source code   $SiteName = "FR1" $ServerSite = "sccm" $Mycoll = @() foreach ($obj in (Get-WmiObject -Class SMS_R_SYSTEM -Namespace "root\sms\site_$SiteName" -computerName $ServerSite)) { Write-Host $obj.NetbiosName $obj.MACAddresses $obj.OperatingSystemNameandVersion $Mydetails = "" | Select-Object PCName, MacAddress, OS If ($([String]$obj.MACAddresses) -eq "") { $Mydetails.PCName = $obj.NetbiosName $Mydetails.MacAddress = "Nul" $Mydetails.OS = $obj.OperatingSystemNameandVersion } Else { $Mydetails.PCName = $obj.NetbiosName $Mydetails.MacAddress = [String]$obj.MACAddresses $Mydetails.OS = $obj.OperatingSystemNameandVersion } $Mycoll += $Mydetails } $Mycoll | Out-GridView

Block Windows XP using selective Ciphers on Citrix NetScaler

Henny Louwers Blog - Tue, 05/06/2014 - 09:48
As you probably know Windows XP is no longer being supported by Microsoft. No (security) updates will be made available for Windows XP making it possibly vulnerable for future exploits. As an organization you will have to decide what you are going to do about these (probably unmanaged) Windows XP workplaces. There will still be […]
