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

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

If you dont want to login with password everytime or you want to use autossh then you should think about Key Login or Key based authentication in SSH.
Generate SSH-Key:
ssh-keygen
by default they are saved here
/home/pi/.ssh/
pi@pi:~/.ssh $ ls -lart insgesamt 16 drwxr-xr-x 20 pi pi 4096 Jän 3 18:47 .. -rw-r--r-- 1 pi pi 390 Jän 3 18:47 id_rsa.pub -rw------- 1 pi pi 1679 Jän 3 18:47 id_rsa drwx------ 2 pi pi 4096 Jän 3 18:47 .

Copy to remote machine (where you want to login without password)
vi /user/.ssh/authorized_keys
copy the content inside of this file.
SSH Connection to the host should now be possible without using password.
Makes also AutoSSH possible:
autossh -R 20000:localhost:22 root@domain.com
to connect from the other side:
ssh -p 20000 pi@localhost
vi /etc/networking/interfaces auto eth0 iface eth0 inet static address 192.168.0.99 netmask 255.255.255.0 gateway 192.168.0.1 sudo systemctl disable dhcpcd sudo systemctl enable networking reboot
Recieved 2 additional Raspis and couldnt’stop setting them up unfortunately the display ordered was broken so i didnt build the mobile RetroPi. So I tried it with my cheap china beamer:
Longrunner Cam with Raspberry and self build Lego Case.
Unfortunately broken display (Raspi HD TFT Hat 800×480).
But a 10″ touch screen and case arrived
+ Raspberry Pi 3 B+
+ Anker PowerBar (10000 mAh)
Installed NetPi Image from: https://drive.google.com/drive/folders/1pCzC8NRPJU0gfBHewlNSo_Z0O3xk7fbY

Install additional Kali-Tools
apt-get install git # git clone https://github.com/LionSec/katoolin.git && sudo cp katoolin/katoolin.py /usr/bin/katoolin chmod +x /usr/bin/katoolin katoolin
establish remote ssh-connection via ssh reverse tunnel (provides ssh-connection to rasp in a network via a server/device with a public ip)
on the raspberry:
ssh -R 2222:localhost:22 loginOfServerIP@ServerIPon server side to connect back to raspberry:
ssh -p 2222 loginOfComputerWithoutPublicIP@localhost
verify usage of autossh if regularely needed
