If a WSUS server fails to obtain updates with the following error: “wsus the request failed with http status 404 not found” this might be because it still uses an old/outdated URL (https://fe2.update.microsoft.com/v6) to obtain the updates from.
This can be checked and changed with the following PS1 Snippet:
$server = Get-WsusServer
$config = $server.GetConfiguration()
# Check current settings before you change them
# Update the settings if MUUrl is https://fe2.update.microsoft.com/v6
$config.MUUrl = "https://sws.update.microsoft.com"
$config.RedirectorChangeNumber = 4002
Restart-Service *Wsus* -v
Dovecot comes with a proprietary mailbox-format (sd/mdbox) that provides some benefits in regard of compression and performance but is not really readable with nothing else than an editor.
It seems that there are very little information on how to convert the sd/mdbox-fomat to mbox (at least nothing copy and paste like if you aren’t a dovecot admin and have no clue ;))
So here is one possible-way it could be archived:
To work around adapting the dovecot-config and running a dovecot-service for dsync to use, we can also pass configuration parameters (by default dsync uses the dovecot-configuration file stored at /etc/dovecot/dovecot.conf) directly to dsync. With that trick there is no need to configure & start a dovecot service.
An example command to convert a mailbox in mdbox-format located in the users home dir under mail to mbox format would look like:
My printer at home is powered of most of the time to save power as I’ll only print a couple of pages once every while.
As i was teached that technicians shall be lazy I use a Sonoff POW R2 to work around getting up and switching on the printer when I want to use it. The Sonoff was flashed with Tasmota to as I don’t want some chinese company to have some backdoor within my IOT-home net.
However, I still had to open up the sonnoff webpage every time and hit the power-on-button for my printer to come up and that’s still some work to do which could be avoided in honor of laziness.
So, the ingridents to a lazy but power saving printer are:
We can configure a Task that’s running in case a specific event log entry is appended to the event log and call the printer’s API to switch on the power every time somebody adds a new print job to the OS printer queue.
Event log config (eventvwr.msc)
The entry we want is: “Microsoft-Windows-PrintService/Operational” (Applications and Service Logs -> Microsoft -> Windows -> PrintService : Operational) That log needs to be enabled first:
Once that’s done there will be new entries every time a new printjob is added:
The interesting part is the Event with the ID 800 -> that’s the one we are looking for as it logs that there is a new spooling job.
Create a Batch-Script to call the Tasmota API
That’s pretty easy. I suggest to simply create a batch script witht he following content:
As curl already comes with newer installations we can simply use it for our call. A powershell could also be used, but by creting a batch script we do not have to deal with the PS-execution policy settings and getting them correct to work.
Create a Task (taskschd.msc)
A new task needs to be created. The Trigger is a specific event-log enty:
With the correct event configured:
As an action we just want to start a program which is the batchscript witht he content from above.
Once that’s done, the script will be run by the task scheduler every time someone hits the “print” button. Running the script will power up the printer automatically and Windows will print the page as soon as the printer is reachable. – so nomore getting up to power the printer manually 🙂
Quite a lot of new Android devices come with lots of bloatware that is preinstalled on the phone/tablet. For some apps it’s possible to deactivate these apps in the built in app management. However, most apps are installed as system apps and do not provide the possibility to be uninstalled.
Thankfully there is a possibility to also remove these apps via ADB.
Before removing any app it’s advised to first create a backup of all the installed APKs in case you remove any app that might be needed and therefore cause errors.
The above script will create a backup of all APKs currently installed on the device (including the ones which have been installed by the user). To successfully run the script, adb needs to be in the path and initially pairing between the PC and the Android device must be established.
Removing the bloatware:
adb shell pm uninstall--user 0 <packagename>
#e.g. for AR-emoti-apks provided by samsung
adb shell pm uninstall --user 0 com.samsung.android.aremoji
Lists of mappings between the readalbe name (like in the Android apps management) and the package name (for Samsung devices) can be found on https://docs.samsungknox.com (e.g. https://docs.samsungknox.com/CCMode/T878U_Q.pdf)
