Little dirty helper to prevent forced password change after x day.

Import-Module ActiveDirectory

Clear-Host

$TXTFile = "C:\Users\user\Desktop\txt.txt"

$Accounts = @()

@(gc $TXTFile) -match '\S'|out-file $TXTFile

$Accounts = Get-Content $TXTFile

foreach($account in $Accounts){

Get-ADUser -Identity $account -Properties * | Select-Object Displayname, PasswordLastSet

Set-ADuser -Identity $account -ChangePasswordAtLogon $True

Set-ADuser -Identity $account -ChangePasswordAtLogon $False

}

Echo ""

The reasonable solution would be to add the -dsaparam option.

1	openssl dhparam -dsaparam -out /etc/ssl/private/dhparam.pem 4096

For comparison.

time openssl dhparam -dsaparam -out dhparam.pem 4096

Generating DSA parameters, 4096 bit long prime

openssl dhparam -dsaparam -out dhparam.pem 4096 4,42s user 0,15s system 99% cpu 4,574 total

time openssl dhparam -out dhparam.pem 4096

Generating DH parameters, 4096 bit long safe prime, generator 2

This is going to take a long time

openssl dhparam -out dhparam.pem 4096 100,27s user 1,60s system 99% cpu 1:41,93 total

Raspberry Pi Kiosk System

Veröffentlicht am 15. Juni 2020

Hier mal die Kurzform für ein Kiosk System mit dem Raspberry Pi und der Lite Version von Raspbian / Raspberry Pi OS

Los geht’s…

sudo su

1	apt update && apt upgrade -y && apt dist-upgrade -y

1	rpi-update && shutdown -r now

1	apt install --no-install-recommends xserver-xorg x11-xserver-utils xinit openbox

1	apt-get install --no-install-recommends chromium-browser -y

Openbox Konfig anpassen

1	nano /etc/xdg/openbox/autostart

# Disable any form of screen saver / screen blanking / power management

xset s off

xset s noblank

xset -dpms

# Allow quitting the X server with CTRL-ATL-Backspace

setxkbmap -option terminate:ctrl_alt_bksp

# Start Chromium in kiosk mode

sed -i 's/"exited_cleanly":false/"exited_cleanly":true/' ~/.config/chromium/'Local State'

sed -i 's/"exited_cleanly":false/"exited_cleanly":true/; s/"exit_type":"[^"]\+"/"exit_type":"Normal"/' ~/.config/chromium/Default/Preferences

chromium-browser --no-default-browser-check --check-for-update-interval=604800 --disable-infobars --kiosk 'http://google.com'

–check-for-update-interval=604800 unterbindet die nervigen Updatehinweise.

Kurz testen, wer Lust dazu hat.

startx -- -nocursor

startx --

Mit / ohne Cursor, je nach dem, was benötigt wird, mit Cursor können Login Daten hinterlegt werden, wenn nötig.

Strg-Alt-Backspace stoppt die ganze Aktion wieder.

Tragen wir das Ganze noch für den Autostart in die .bash_profile ein.

Btw. wieder mit / ohne Cursor…

[[ -z $DISPLAY && $XDG_VTNR -eq 1 ]] && startx -- -nocursor

[[ -z $DISPLAY && $XDG_VTNR -eq 1 ]] && startx --

Neustart

1	sudo shutdown -r now

Tipps…

wenn Chromium oder der X Server crasht, Strg-Alt-Backspace drücken und neustarten, startx — -nocursor / startx —
wird ein Terminal am laufenden System benötigt, einfach Strg-Alt-F2 drücken und schwupps gib’s ein Terminal, wenn fertig dann Strg-Alt-F1 drücken
