Some time ago I set up a Raspberry and expanded the filesystem to 16GB. Unfortunately I wanted to share the Image afterwards. I tried to reduce the size the easy way and succeeded. Procecure was:

– Created the *.img from the SD-Card of Raspberry via Win32Imager (via Read function)
– Copied the big *.img to a USB Stick (32 GB)
– Created Linux Live CD (Linux Mint) and wrote it to a USB-Stick to boot from it afterwards
– of course also plugged in the USB Stick with the img
– mounted the USB Drive and opened a Console and changed the dir (cd) where the image is

After booting into Linux Mint
– I installed quemu utils via

sudo apt-get install qemu-utils

– checked the img via

fdisk -l image.img

I saw that there are 2 partitions holding only 2,1 Gigs so I did

qemu-img resize vdisk.img 3GB

afterwards I wrote the img to an SD-Card and booted it successfully in a RPI3

A subpage regarding OpenGlider Network soon to come (glider.untony.org)

Script copies UltraVNC to target client (C:\vnc\) and executes UltraVNC with configurable settings. Launches VNC Viewer afterwards and removes VNC (optional).

Requirements and Usage:
- Copy psexec.exe to C:\Windows
- Run the Powershell with Admin-Rights / elevated Console
- User has to be admin on the target and local machine
- Default password = 123

– Save the Script and create a folder on the same level called „UltraVNC“
– Copy UltraVNC Programm Files to the UltraVNC folder
– Run vnc_deploy.ps1 (elevated, user has to be admin on the targeted client)

The ACL part is variable if you use it in an Domain environment. Start uvnc_settings.exe and configure Domain Access with groups or edit the *ultravnc.ini and change to:

[ultravnc]
passwd=000000000000000000
passwd2=000000000000000000
[admin]
UseRegistry=0
MSLogonRequired=1
NewMSLogon=1

And change acl.txt
