Raspberry hooked to a laptop (Ubuntu 18.04) NO Router

RasPBX-Begin.txt

Equipment
   laptop w/ Ubuntu 18.04
   Dynex: Mini Memory Card Reader/Writer
   Cana Kit RPi 3 B+
   SanDisk: Ultra microSDXC UHS-1 Card and Adapter, 64DB

To format SD Card
  Download
     Etcher www.canakit.com/tools/etcher
        To format SD card w/ adapter and put Raspbian OS on it
  Download OS zip file
     I'm using RasPBX for the asterisk software.
     You can choose another OS zip file
        You may want a desktop on your's
     RasPBX http://www.raspberry-asterisk.org/downloads/

     I extraced the 'img' file using the Archive Manager' when I
     downloaded the zip file.

  Excute the Etcher API file
     $ ls Downloads/*.zip
     $ mkdir Etcher
     $ unzip -d Etcher Downloads/balena-etcher-electron-1.4.9-linux-x64.zip
     $ cd Etcher

     Forget:   Failed to load module "canberra-gtk-module"
         The package doesn't exist in Ubuntu land
     $ ./balena-etcher-electron-1.4.9-x86_64.AppImage

Place micro card in the RPi

Plug the ethernet cable into the RPi and laptop
  boot or reboot RPi (sudo reboot)

  The IP address should be echo out just before the login prompt

  Log in to RPi
  ifconfig
     gather the IPA and netmask

  On the laptop
     Settings
       Network
          Add a 'Wired' profile (use the '+' button)
             Identify tab
                give it a 'Name'
             IPv4 tab
                Choose 'Manual'
                Come up with a IP address on the same network as the RPi
                Use the same netmask
                   'Apply' button

     ssh to IP address of RPi
       No monitor or extra keyboard needed!

If your card is larger than 4GB, expand the file system to fill it. 
   sudo raspi-config
      Advanced Options
         Expand Filesystem
         
If you want to see if 'asterisk' is running
     Open a browser to the RPi IP address
        You'll get the FreePBX Admin web page

Create new ssh host keys to have individual keys for every setup:
      $ sudo regen-hostkeys
      After this step your ssh client will warn about a changed host key on 
      your next ssh connect.
Choose your timezone:
      $ configure-timezone   
Configure locale settings:
      $ sudo dpkg-reconfigure locales
          Choose en_US.UTF-8 UTF-8
Configure keyboard settings (not needed when working with ssh only):
      $ sudo dpkg-reconfigure keyboard-configuration

If you have a different OS (NOT RasPBX) and you have a desktop AND
  you want to do a remote desktop, you will need to google something like
     VNC setup on Raspberry Pi from Ubuntu
