Raspberry Pi - Things to do after installing Raspbian Jessie

This is a quick summary. More will be added to the to-do list as I learn more about Raspberry Pi and Raspbian.

Upgrade the packages existing on the machine

pi@raspberrypi:~ $ sudo apt-get update



pi@raspberrypi:~ $ sudo apt-get upgrade


Reference:

Configure the Raspbian system. 

Reference: http://elinux.org/RPi_raspi-config

pi@raspberrypi:~ $ sudo raspi-config

Update the RPi raspi-config to the latest version


Set local time



Select region, then select city to set the local time.

Expand the Filesystem



Note, make sure to reboot the system for the expanded filesystem to take effect!!

Enable peripherals


Select the peripherals to be enabled.


Change GPU memory allocation

If the Pi will be used as a headless device (without using monitor), you could set the memory allocated to GPU to zero.





That's all for my typical application. The section below is rarely used..

--------------------------------------------------------------------------------------------------------------------------

Install Screen

pi@raspberrypi:/ $ sudo apt-get update

pi@raspberrypi:/ $ sudo apt-get install screen


For more on how to use Screen, refer to the link below:

Fix the dependencies after a failed install - if any.

sudo apt-get update

sudo apt-get install -f

Download and install TightVNC on the computer that will be used to remotely view and operate X-Window.

http://www.tightvnc.com/download.php

Install X-Term and Download Manager

sudo apt-get install xterm
sudo apt-get install uget
sudo apt-get install tint2

Install tightvncserver

sudo apt-get update
sudo apt-get install tightvncserver

This is needed for accessing the X-window remotely (headlessly).

Note, there is a mistake in the command for installing tightvncserver on the Pi.

Setting up the programming environment

Python & C

Installing the Google API client library

Node-RED

Launch it from the x-window desktop.


Following the instruction in the console by issuing "sudo apt-get install npm" in PuTTY to install npm.



Once the installation is completed, launch the Epiphany browser and enter the IP address given in the Node-RED console (see above, in my case it's 192.168.1.24:1880).


The Node-RED is up and running.

Check the time and set the correct date and time

Because the Pi has no real time clock (RTC) it's already configured as an NTP client using the Debian NTP servers. As long as the Pi is connected to the internet, it should display the correct time. However, if the date and time are incorrect, it's possible that the Pi is configured for a different time zone other than your current one (https://www.raspberrypi.org/forums/viewtopic.php?f=26&t=10291).

Use the "date" command to show the current date and time.


If the date and time are incorrect, use "sudo dpkg-reconfigure tzdata" to select the correct time zone.


Reboot and issue the "date" command again to check the date and time again.

Configure the system to reboot at 04:00 every morning. 

Reference: https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=118069

Issue "crontab -e" to launch the crontab configuration file and enter "0 4 * * * sudo /sbin/shutdown -r now" to set the system to auto reboot at 04:00 every morning.

Note,
Issue "uptime -s" to check the time when the system is up. Or, issue "uptime" to check how long has the system been up.

Install ssmtp and mailutils to send emails in command line.

Note,
Need to create a seperate Gmail account for this as the username and password are stored in the SD card in plain text.

If Putty is used, make changes to its configuration to solve the problem of "Network Error: Software caused connection abort"

Note,

At first, I changed the netsh setting as instructed below, but it didn't solve the problem.


Then I change the Seconds between keepalives to 5 seconds and it solved the problem.
