rpi3-scripts

This repo contains Tom Lutz's personal notes and scripts for configuring a new Raspberry Pi 3 Model B with some applications, based on the default raspbian installation.

References

This is not all original material. I leveraged tutorials from the following sites:

Quake 3 Arena

  • ioquake3 via github.com/tommylutz/quake3 (has minor fixes to link line and build script)
sudo apt-get install libsdl1.2-dev
git clone https://github.com/tommylutz/quake3.git
cd quake3
./build_rpi_raspbian.sh

Find pak0.pk3, pak1.pk3, ... pak8.pk3 files from a legit copy of Quake 3 Arena, and copy to build/release-linux-arm/baseq3/

./start_server.sh

The start_server.sh script will emit instructions on what to add to /etc/rc.local to start up quake 3 dedicated server on boot, if you'd like.

Wifi Hotspot with NAT Routing

hostapd

The hostapd package is required to turn RPi3 into a wifi hotspot. After completing these steps, you should be able to see the SSID of your Raspberry Pi broadcasting (Pi3-AP unless you changed it). You will not get an IP address until you configure dnsmasq (later).

First, install hostapd using aptget.

sudo apt-get install dnsmasq hostapd

Next, create the hostapd config file, /etc/hostapd/hostapd.conf

# This is the name of the WiFi interface we configured above
interface=wlan0

# This is the name of the network
ssid=Pi3-AP

# Use the 2.4GHz band
hw_mode=g

# Use channel 6
channel=6

# Enable 802.11n
ieee80211n=1

# Enable WMM
wmm_enabled=1

# Enable 40MHz channels with 20ns guard interval
ht_capab=[HT40][SHORT-GI-20][DSSS_CCK-40]

# Accept all MAC addresses
macaddr_acl=0

# Use WPA authentication
auth_algs=1

# Require clients to know the network name
ignore_broadcast_ssid=0

# Use WPA2
wpa=2

# Use a pre-shared key
wpa_key_mgmt=WPA-PSK

# The network passphrase
wpa_passphrase=raspberry

# Use AES, instead of TKIP
rsn_pairwise=CCMP

Tell hostapd where the config file is by editing /etc/default/hostapd

DAEMON_CONF="/etc/hostapd/hostapd.conf"

Edit /etc/network/interfaces to set wlan0 to static ip address:

allow-hotplug wlan0
iface wlan0 inet static
    address 192.168.2.1
    netmask 255.255.255.0
    network 192.168.2.0
    broadcast 192.168.2.255

Restart your wlan0 interface and check that it has the correct IP address assigned.

sudo ifdown wlan0
sudo ifup wlan0
ifconfig wlan0

Start hostapd

sudo service hostapd start

Check that the access point is visible from a wifi client, such as your phone.

dnsmasq

First, install the package

sudo apt-get install dnsmasq

Next, configure your DNS service in /etc/dnsmasq.conf This is the entire contents of the file. You may wish to save the original one to .sav or something.

interface=wlan0
listen-address=192.168.2.1
bind-interfaces
server=8.8.8.8
domain-needed
bogus-priv
dhcp-range=192.168.2.100,192.168.2.200,12h
dhcp-option=option:router,192.168.2.1

Fire up the service (yes, it will auto start on next boot)

sudo service dnsmasq start

IP Routing / NAT

Set up IP routing rules

sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE  
sudo iptables -A FORWARD -i eth0 -o wlan0 -m state --state RELATED,ESTABLISHED -j ACCEPT  
sudo iptables -A FORWARD -i wlan0 -o eth0 -j ACCEPT  

Add this line to /etc/rc.local

echo 1 > /proc/sys/net/ipv4/ip_forward

Also run this so it takes effect immediately

sudo sh -c "echo 1 > /proc/sys/net/ipv4/ip_forward"

Configure iptables persistently. First, export iptables config to a file:

sudo sh -c "iptables-save > /etc/iptables.ipv4.nat"

Now add this to /etc/rc.local to load the config on boot:

iptables-restore < /etc/iptables.ipv4.nat

Citrix Receiver

  • Include certificate installation
  1. Download the "Receiver for Linux (ARM HF)" debian package from https://www.citrix.com/downloads/citrix-receiver/linux/receiver-for-linux-latest.html (wget may not work, as you have to accept the license)
wget https://downloads.citrix.com/12939/icaclient_13.5.0.10185126_armhf.deb?__gda__=1489922811_35d02cb8c45ec8bf003218ef82d5d6dc
  1. Try to install the package, but fail miserably due to missing dependencies. sudo apt-cache search <SEARCH TERM> to search for the appropriate packages and sudo apt-get install <PACKAGES> to install them
  2. Symlink root certs from mozilla into the Citrix folder.
sudo ln /usr/share/ca-certificates/mozilla/* /opt/Citrix/ICAClient/keystore/cacerts/
