System

Boot Up

    Normally, you have to login as Username : PI and Password : raspberry, when you first boot up. it would not go to GUI but i will show you how later on. you have to type "startx" to start GUI.

Do it all the time

  • Open Terminal (LXTerminal)
  • Keep update : sudo apt-get update 
  • Clear Up Disk Space : $ sudo apt-get clean
  • Go to Basic Setup from Terminal : sudo raspi-config
  • Remore Application : sudo apt-get --purge autoremove packagename
  • Check Disk Space : $ df 
  • Search All linked file : sudo find . -type l -exec ls -l {} \; | grep [someString] > allfile.txt 
  • sudo rpi-update ( Update Raspi Frimware )

Auto Start on Boot

Non-GUI

If Linux Script
  • $ sudo chmod +755 myScript.sh
  • $ sudo nano /etc/rc.local
  • Add : sudo ./xxx/myScript.sh & to end of rc.local
  • Reboot
OR
  • Create a .conf file into /etc/init 
  • E.g. 
  • # gps data logger service

    description "GPS Data Logger service"
    author "User"

    start on runlevel [2345]
    stop on runlevel [016]
    chdir /home/user/
    exec python /home/user/gps_data.py
    respawn
    OR
  • Script file into /etc/init.d
  • E.g.
#!/bin/bash # /etc/init.d/servoblaster ### BEGIN INIT INFO # Provides: servoblaster # Required-Start: $remote_fs $syslog # Required-Stop: $remote_fs $syslog # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Example initscript # Description: This service is used to manage a servo ### END INIT INFO case "$1" in start) echo "Starting servoblaster" /home/pi/servoblaster/PiBits/ServoBlaster/user/servod ;; stop) echo "Stopping servoblaster" killall servod ;; *) echo "Usage: /etc/init.d/servod start|stop" exit 1 ;; esac exit 0
  • If Python
    • $ Add : sudo python myScript.py

GUI

  • Auto Start Folder and Sample :
    • $ cd /home/pi
    • $ cd .config
    • $ mkdir autostart
    • $ cd autostart
    • Create xxxx.desktop 
    • Or copy Desktop xxx.desktop to /home/pi/.config/autostart
Kill Background Process
  • $ sudo killall my_project.a

Wifi and VPN

    If you not connect with internet that mean you can't do anything, right. Two way to do it, buy a USB wifi connecter e.g. IEEE802.11n and plug into USB or Connect with Cable if you like. 

Wifi

    After you plug you USB Wifi connecter then Click "WIFI Config", Scan and Add to list and connect, Easy !

SSH

  • (Recommanded)
  • Make Sure your system is enabled SSH from basic config otherwise go back to "sudo raspi-config" to enable before continues.
  • Test by MAC : "ssh <IP> -l <username>" e.g. ssh 192.168.0.105 -l pi

Services Start and Stop

Under Debian Linux startup files are stored in /etc/init.d/ directory and symbolic linked between /etc/rcX.d/ directory exists. Debian Linux uses System V initialization scripts to start services at boot time from /etc/rcX.d/ directory. Debian Linux comes with different utilities to remove unwanted startup file: 

(A) rcconf

This tool configures system services in connection with system runlevels. It turns on/off services using the scripts in /etc/init.d/. Rcconf works with System-V style runlevel configuration. It is a TUI(Text User Interface) frontend to the update-rc.d command. 

Install rcconf in Debian

#apt-get install rcconf

To start rconf, login as root user and type rcconf

# rcconf

Select the service you would like to enable or disable.

(B) sysv-rc-conf 

sysv-rc-conf provides a terminal GUI for managing "/etc/rc{runlevel}.d/" symlinks. The interface comes in two different flavors, one that simply allows turning services on or off and another that allows for more fine tuned management of the symlinks. Unlike most runlevel config programs, you can edit startup scripts for any runlevel, not just your current one. 

Install sysv-rc-conf in debian

#apt-get install sysv-rc-conf

This will install sysv-rc-conf.Now you need to run the following command

# sysv-rc-conf

Select the service you would like to enable or disable. 

Both sysv-rc-conf and rcconf are best tools to use on Remote Debian Linux or when GUI is not available

You can also use update-rc.d script as follows (update-rc.d removes any links in the /etc/rcX.d directories to the script /etc/init.d/service):

# update-rc.d -f {SERVICE-NAME} remove

For example to stop xinetd service you can type command as follows:

# update-rc.d -f xinetd remove

IP Address Control and list

  • $ iwlist wlan0 scanning
  • Get IP Address : ifconfig | grep inet | cut -d':' -f2 | cut -d' ' -f1 | grep -v 127
