XMEN BLOGGER: Nikon D7000 - Raspberry Pi as an Access Point to control your camera w/Raspbian

From:
http://dslrdashboard.info/
http://digicamcontrol.com/doc/

You need:

- Raspberry Pi 2B, because it has 4 USB port, and I need it to control my Nikon camera and my Celestron teelescope (if you need more info, check this) with Raspbian installed.
- USB Wifi dongle compatible.
- External battery (5V output) to do power to your Raspberry Pi.
- USB cable (USB to mini-USB), to connect raspberry pi to Nikon D7000 camera.

First step:

- Install Raspbian (if you have doubts, please check raspbian.org.

- Update your Raspberry Pi from repositories:


pi@raspsrv $ sudo apt-get update

pi@raspsrv $ sudo apt-get upgrade

- And install rpi-update:


pi@raspsrv $ sudo apt-get install rpi-update

pi@raspsrv $ sudo rpi-update

Please, reboot when finish!!

- Troubleshooting... (If needed)


pi@raspsrv $ sudo apt-get install ca-certificates



pi@raspsrv $ sudo apt-get install ntpdate

pi@raspsrv $ sudo ntpdate -u ntp.ubuntu.com

Second step:

Configure your Raspberry Pi as an Acces Point.

1. Install all that you need:


pi@raspsrv $ sudo apt-get install hostapd isc-dhcp-server



# Probably you don't need install this:

pi@raspsrv $ sudo apt-get install iptables-persistent

If you have a non-common WiFi adapter, you can update hostapd driver from adafruit...


pi@raspsrv $ wget http://adafruit-download.s3.amazonaws.com/adafruit_hostapd_14128.zip

pi@raspsrv $ unzip adafruit_hostapd_14128.zip



pi@raspsrv $ sudo mv /usr/sbin/hostapd /usr/sbin/hostapd.ORIG

pi@raspsrv $ sudo mv hostapd /usr/sbin

pi@raspsrv $ sudo chmod 755 /usr/sbin/hostapd

2. Edit your interfaces file to configure wlan0 adapter:

pi@raspsrv $ cat /etc/network/interfaces


auto lo



iface lo inet loopback

iface eth0 inet dhcp

#iface eth0 inet static

# address 192.168.0.190

# netmask 255.255.255.0

# gateway 192.168.0.1



allow-hotplug wlan0

#iface wlan0 inet manual

#wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf

#iface default inet dhcp

iface wlan0 inet static

  address 192.168.5.1

  netmask 255.255.255.240

  gateway 192.168.0.1



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

3. Edit your DHCP daemon config file:

pi@raspsrv $ cat /etc/dhcp/dhcpd.conf


#

# Sample configuration file for ISC dhcpd for Debian

#

#



# The ddns-updates-style parameter controls whether or not the server will

# attempt to do a DNS update when a lease is confirmed. We default to the

# behavior of the version 2 packages ('none', since DHCP v2 didn't

# have support for DDNS.)

ddns-update-style none;



# option definitions common to all supported networks...

##option domain-name "example.org";

##option domain-name-servers ns1.example.org, ns2.example.org;



default-lease-time 600;

max-lease-time 7200;



# If this DHCP server is the official DHCP server for the local

# network, the authoritative directive should be uncommented.

#authoritative;

authoritative;



# Use this to send dhcp log messages to a different log file (you also

# have to hack syslog.conf to complete the redirection).

log-facility local7;



# No service will be given on this subnet, but declaring it helps the

# DHCP server to understand the network topology.



#subnet 10.152.187.0 netmask 255.255.255.0 {

#}



# This is a very basic subnet declaration.



#subnet 10.254.239.0 netmask 255.255.255.224 {

#  range 10.254.239.10 10.254.239.20;

#  option routers rtr-239-0-1.example.org, rtr-239-0-2.example.org;

#}



# This declaration allows BOOTP clients to get dynamic addresses,

# which we don't really recommend.



#subnet 10.254.239.32 netmask 255.255.255.224 {

#  range dynamic-bootp 10.254.239.40 10.254.239.60;

#  option broadcast-address 10.254.239.31;

#  option routers rtr-239-32-1.example.org;

#}



# A slightly different configuration for an internal subnet.

#subnet 10.5.5.0 netmask 255.255.255.224 {

#  range 10.5.5.26 10.5.5.30;

#  option domain-name-servers ns1.internal.example.org;

#  option domain-name "internal.example.org";

#  option routers 10.5.5.1;

#  option broadcast-address 10.5.5.31;

#  default-lease-time 600;

#  max-lease-time 7200;

#}



# Hosts which require special configuration options can be listed in

# host statements.   If no address is specified, the address will be

# allocated dynamically (if possible), but the host-specific information

# will still come from the host declaration.



#host passacaglia {

#  hardware ethernet 0:0:c0:5d:bd:95;

#  filename "vmunix.passacaglia";

#  server-name "toccata.fugue.com";

#}



# Fixed IP addresses can also be specified for hosts.   These addresses

# should not also be listed as being available for dynamic assignment.

# Hosts for which fixed IP addresses have been specified can boot using

# BOOTP or DHCP.   Hosts for which no fixed address is specified can only

# be booted with DHCP, unless there is an address range on the subnet

# to which a BOOTP client is connected which has the dynamic-bootp flag

# set.

#host fantasia {

#  hardware ethernet 08:00:07:26:c0:a5;

#  fixed-address fantasia.fugue.com;

#}



# You can declare a class of clients and then do address allocation

# based on that.   The example below shows a case where all clients

# in a certain class get addresses on the 10.17.224/24 subnet, and all

# other clients get addresses on the 10.0.29/24 subnet.



#class "foo" {

#  match if substring (option vendor-class-identifier, 0, 4) = "SUNW";

#}



#shared-network 224-29 {

#  subnet 10.17.224.0 netmask 255.255.255.0 {

#    option routers rtr-224.example.org;

#  }

#  subnet 10.0.29.0 netmask 255.255.255.0 {

#    option routers rtr-29.example.org;

#  }

#  pool {

#    allow members of "foo";

#    range 10.17.224.10 10.17.224.250;

#  }

#  pool {

#    deny members of "foo";

#    range 10.0.29.10 10.0.29.230;

#  }

#}



subnet 192.168.5.0 netmask 255.255.255.240 {

range 192.168.5.5 192.168.5.10;

option broadcast-address 192.168.5.15;

option routers 192.168.5.1;

default-lease-time 600;

max-lease-time 7200;

option domain-name "wifi.local";

option domain-name-servers 8.8.8.8, 8.8.4.4;

}

4. Edit your DHCP server config file:

pi@raspsrv / $ cat /etc/default/isc-dhcp-server


# Defaults for isc-dhcp-server initscript

# sourced by /etc/init.d/isc-dhcp-server

# installed at /etc/default/isc-dhcp-server by the maintainer scripts



#

# This is a POSIX shell fragment

#



# Path to dhcpd's config file (default: /etc/dhcp/dhcpd.conf).

#DHCPD_CONF=/etc/dhcp/dhcpd.conf



# Path to dhcpd's PID file (default: /var/run/dhcpd.pid).

#DHCPD_PID=/var/run/dhcpd.pid



# Additional options to start dhcpd with.

# Don't use options -cf or -pf here; use DHCPD_CONF/ DHCPD_PID instead

#OPTIONS=""



# On what interfaces should the DHCP server (dhcpd) serve DHCP requests?

# Separate multiple interfaces with spaces, e.g. "eth0 eth1".

##INTERFACES=""

INTERFACES="wlan0"

5. Edit your host APD config file:

pi@raspsrv / $ cat /etc/hostapd/hostapd.conf


interface=wlan0

driver=nl80211

#driver=rtl871xdrv

ssid=MyPi

hw_mode=g

channel=6

macaddr_acl=0

auth_algs=1

ignore_broadcast_ssid=0

wpa=2

wpa_passphrase=Raspb3rry

wpa_key_mgmt=WPA-PSK

wpa_pairwise=TKIP

rsn_pairwise=CCMP

6. Edit your host APD daemon config file:

pi@raspsrv / $ cat /etc/default/hostapd


# Defaults for hostapd initscript

#

# See /usr/share/doc/hostapd/README.Debian for information about alternative

# methods of managing hostapd.

#

# Uncomment and set DAEMON_CONF to the absolute path of a hostapd configuration

# file and hostapd will be started during system boot. An example configuration

# file can be found at /usr/share/doc/hostapd/examples/hostapd.conf.gz

#

#DAEMON_CONF=""

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



# Additional daemon options to be appended to hostapd command:-

#  -d   show more debug messages (-dd for even more)

#  -K   include key data in debug messages

#  -t   include timestamps in some debug messages

#

# Note that -B (daemon mode) and -P (pidfile) options are automatically

# configured by the init.d script and must not be added to DAEMON_OPTS.

#

#DAEMON_OPTS=""

7. Edit your SYSCTL config file:

pi@raspsrv / $ cat /etc/sysctl.conf


#

# /etc/sysctl.conf - Configuration file for setting system variables

# See /etc/sysctl.d/ for additonal system variables

# See sysctl.conf (5) for information.
#



#kernel.domainname = example.com



# Uncomment the following to stop low-level messages on console
kernel.printk = 3 4 1 3



###############################################################

# Functions previously found in netbase

#



# Uncomment the next two lines to enable Spoof protection (reverse-path filter)

# Turn on Source Address Verification in all interfaces to

# prevent some spoofing attacks

#net.ipv4.conf.default.rp_filter=1

#net.ipv4.conf.all.rp_filter=1



# Uncomment the next line to enable TCP/IP SYN cookies

vm.min_free_kbytes = 8192

8. Add a iptables file:

pi@raspsrv / $ cat /etc/iptables.ipv4.nat


# Generated by iptables-save v1.4.14 on Thu Nov 26 08:15:51 2015

*filter

9. Add a iptables file:

pi@raspsrv / $ cat /etc/iptables.ipv4.nat


pi@raspsrv $ sudo service hostapd start

pi@raspsrv $ sudo service isc-dhcp-server start



pi@raspsrv $ sudo service hostapd status

pi@raspsrv $ sudo service isc-dhcp-server status



pi@raspsrv $ sudo update-rc.d hostapd enable

pi@raspsrv $ sudo update-rc.d isc-dhcp-server enable
