HELP SETTING UP A NEW RASPBERRY PI

https://projects.raspberrypi.org/en/projects/raspberry-pi-getting-started

A. Formatting a previously used MicroSD (not needed for new card?)
  
  1. Start SDFormatter (Make sure the SD is selected)
  2. Change options to 
      Format Type "Full Overwrite"
      format Size Adjustment "OFF"
  3. Click "Format"
  4. Eject & Reinsert SD

B. Copy latest NOOBS files to SD

C. Put SD into Pi, connect HDMI to HDTV, USB Mouse & Keyboard, then connect Power

D. Select Language & Keyboard

E. Setup WiFi connection

F. Select Raspian OS

G. Click Install, Confirm "Yes" and wait "a few" (about 20-30) minutes

H. When done, will reboot into graphical interface. Need to setup Country, Language,
   timezone, new Pi password, WiFi password

I. Click Next again and it will update the Raspian software if necessary.
   This can take "another few" minutes. The screen goes blank except for flashing
   lightning bolt (space bar unblanks it and shows what's going on).

J. Once system is up to date, it must be rebooted for updates to take effect.

K. To enable remote access, Menu > Preferences > Raspberry Pi Configuration > Interfaces and 
   make sure VNC is set to Enabled (Details in next section). (NOTE: I enabled SSH also to
   allow the use of PuTTY).
   May need to reboot now?

L. Find the Pi's IP address (right click on WiFi on, or use ifconfig command, or etc.) and can
   then remote connect to Pi via VNC app. (Details in next section.)

REMOTE ACCESS TO RASPBERRY PI


NOTE: After initially setting up VNC Viewer as in step K above, do following:

A. Rt click VNC symbol, Change options to uncheck "View Only" and "Pass Special Keys to VNC Server"

B. Change Expert Preference and/or connections Properties to clear Username field

NOTE: At this point only the Pi user can login via VNC. You need to change some of the 
VNC options before any other user, even a sudoer, can log in using the VNC Viewer.


Changes needed for VNC are made by rt-clicking on the VNC icon at 
the top right of the graphical interface and clicking on "options":

Under "Security" submenu, choose Encryption: "Always on" AND
set Authentication: to "VNC Password" and set the password to use (which is
NOT your RealVNC Site Password!) on the "Users and Permissions" submenu

Under Expert submenu, verify that "Authentication" is set to "VncAuth" AND
that "Encryption" is set to to "AlwaysOn" AND 
set "Permissions" to "newuser":d,pi:d,%sudo:f,%adm:f where "newuser" is the
one created in section C below.

NEW VNC Viewer does NOT NEED port forwarding supposedly at the router for accessing
over the internet IF YOU SET it up to connect for CLOUD as well as DIRECt connections.
Changes needed for VNC CLOUD are made by rt-clicking on the VNC icon at 
the top right of the graphical interface and clicking on "Connections":
Add RPi's to the Tean on the VNC App by File/New Connection menu. 


You need to sign into your RealVNC account using it's email address and password.
Here you can also setup or change the password to use when remotely connecting from
the RealVNC Viewer using your VNC team Account. It should be different from
your RealVNC Account password.

From logged in VNC app use the team password but NO USERNAME
You the use the unix username and its unix password to log into the RPi:
3,3w,w,9??---unix user password
REMEMBER TO SHUTDOWN/LOGOUT WHEN DONE


C. Create a new SUDO user via first part of file "CreateNewSudoUserAndRenamePiUser.txt"

D. ONLY WHEN this all works should you remove the file 010-... in the /etc/sudoers.d
directory or edit it to put a # in front of the Pi user, and remove Pi from the
sudo entry in the /etc/group file.
