> Sford wiki: > CHIP do once
These are items which you only need to do once after getting (or re-flashing) your CHIP.
These things should be done in the order presented.

Out of the box, CHIP seems to have a slightly broken "apt-get" system. Fix it:
sudo cu -l /dev/tty.usbmodem2411 -s 115200 sudo nmtui /sbin/ifconfig | grep Bcast # to get IP address ~. # exit from cu ssh 10.0.0.21 sudo apt-get update # Have CHIP retrieve the latest software list sudo apt-get install wireless-tools sudo iwconfig wlan0 power off sudo wget -O/etc/network/if-up.d/wlan_pwr http://fordsfords.github.io/wlan_pwr/wlan_pwr sudo chmod +x /etc/network/if-up.d/wlan_pwr sudo apt-get install -f locales sudo locale-gen en_US en_US.UTF-8 sudo dpkg-reconfigure locales # Select "en_US" locales. sudo dpkg-reconfigure tzdata sudo apt-get upgrade # Update Linux software to the latest versions sudo apt-get install apt-file sudo apt-file update apt-file search curl.h
Out of the box, both the "chip" and "root" accounts have a password of "chip". Given that most people will enable WIFI, this is a Bad Idea (tm). Best security practices is to change "chip" password, and *remove* the root password. You don't want to log in as root, you want to enable "sudo" for select user accounts. Fortunately, out of the box, the "chip" account is enabled for "sudo". If you have a *lot* of root work to do you can always enter "sudo bash".
passwd # change "chip" account's password sudo passwd -l root # lock the root account from direct login sudo sed -i.old /etc/ssh/sshd_config -e'/PermitRootLogin/s/yes/no/' # configure sshd to not allow root sudo service ssh restart
sudo wget -O/usr/local/bin/blink.sh http://fordsfords.github.io/blink/blink.sh sudo chmod +x /usr/local/bin/blink.sh sudo wget -O/etc/systemd/system/blink.service http://fordsfords.github.io/blink/blink.service sudo systemctl enable /etc/systemd/system/blink.service sudo service blink start
sudo apt-get install build-essential # gcc, make, etc. sudo apt-get install git sudo apt-get install python-dev # header files you need to build Python extensions sudo apt-get install python-pip # package manager sudo apt-get install python-smbus # includes i2c-tools
If you want to run an Apache-based web server, you need to install Apache:
sudo apt-get install apache2
If you want to access user accounts' "public_html" areas:
cd /etc/apache2/mods-enabled sudo ln -s ../mods-available/userdir.load sudo ln -s ../mods-available/userdir.conf mkdir ~/public_html
If you want to be able to run CGI-based programs, enable cgi-bin:
sudo ln -s ../mods-available/cgi.load
When Apache is configured to your satisfaction, restart it:
sudo apachectl -k graceful # restart apache
I'm not sure this is valuable, but I did it:
sudo apt-get install git
LED anode is connected through 4.7K to +3.3V; cathode connected to CSID7.
On CHIP:
sudo apt-get update
sudo apt-get install build-essential python-pip python-dev python-smbus git
git clone https://github.com/xtacocorex/Adafruit_Python_GPIO.git
cd Adafruit_Python_GPIO
sudo python setup.py install
cd ..
git clone git://github.com/xtacocorex/CHIP_IO.git
cd CHIP_IO
sudo python setup.py install
cd ..
sudo python
>>> import CHIP_IO.GPIO as G
>>> G.setup("CSID7", G.OUT) # LED turns on, meaning output is 0
>>> G.output("CSID7", G.LOW)
>>> G.input("CSID7")
0
>>> G.output("CSID7", G.HIGH) # LED turns off, meaning output is 1
>>> G.input("CSID7")
1
>>> G.setup("CSID7", G.IN) # LED turns off; output is floating
>>> G.input("CSID7")
1
>>> G.output("CSID7", G.LOW)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
RuntimeError: The GPIO channel has not been setup() as an OUTPUT
>>> G.cleanup()
>>>
On Mac, generate private and public keys:
$ ssh-keygen -t rsa -b 2048 Generating public/private rsa key pair. Enter file in which to save the key (/Users/sford_itunes/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /Users/sford_itunes/.ssh/id_rsa. Your public key has been saved in /Users/sford_itunes/.ssh/id_rsa.pub.
On Mac, transfer public key to CHIP:
scp id_rsa.pub chip@10.0.0.21: authorized_keys
On CHIP, set up ssh:
mkdir .ssh # might say already exists if you've used ssh on chip already chmod 700 .ssh mv authorized_keys .ssh/ chmod 600 .ssh/*
On Mac, test (should not prompt for password):
ssh chip@10.0.0.21 ls
On CHIP, get rsync (may already be installed, but doesn't hurt):
sudo apt-get install rsync
On CHIP get and build fswatch (this takes a while)
wget https://github.com/emcrisostomo/fswatch/releases/download/1.9.2/fswatch-1.9.2.tar.gz tar xzf fswatch-1.9.2.tar.gz cd fswatch-1.9.2 ./configure CXX=g++ make sudo make install sudo ldconfig
