Config

Run on raspian the following command to start a gui-based configuration tool:

raspi-config 

System time and language:

dpkg-reconfigure tzdata                                     #timezone set
dpkg-reconfigure locales                                    #system language
dpkg-reconfigure keyboard-configuration                     #Change keyboard

Keyboard language (/etc/default/keyboard):

# KEYBOARD CONFIGURATION FILE

# Consult the keyboard(5) manual page.

Note: Reboot required to take effect!

Partitioning

Create aditional custom partition:

fdisk -u -c /dev/mmcblk0

Aferwards format new partitions:

mkfs.ext4 -Ltmp /dev/mmcblk0p3
mkfs.ext4 -Ldata /dev/mmcblk0p4

Resize "/"

Reisize “/” (on /dev/mmcblk0p2) to 8GB:

Now you are able to add partitions to the disk or other device with “fdisk” and “mkfs.(ext4)”:

fdisk -u -c /dev/mmcblk0

Aferwards format new partitions:

mkfs.ext4 -Ltmp /dev/mmcblk0p3
mkfs.ext4 -Ldata /dev/mmcblk0p4

Overclocking

Check maximum CPU frequence (e.g. when your CPU is under load):

sudo cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq

Check minimum CPU frequence (when your CPU is idle):

sudo cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq

Check current CPU frequence:

sudo cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq

Time

Sync time via ntpdate:

Uninstall ntp (ressources!).

apt-get purge ntp

Install ntpdate

apt-get install ntpdate                                 #timeserver 

Create a file

vi /etc/cron.d/general

and add content (or similar):

  */20 * * * * root /usr/sbin/ntpdate -s 0.de.pool.ntp.org

The cronjob now syncs the system-time.

ROUTING

Routing wlan0 (inside) and eth1 (inside) to eth0 (outside):

Change “/etc/sysctl.conf”

#net.ipv4.ip_forward=1

to

net.ipv4.ip_forward=1

and save it.

To update the setting:

sysctl -p /etc/sysctl.conf

The following command will check forwarding:

sysctl net.ipv4.ip_forward

Temporary for testing isues and not permanent:

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

Switch of forwarding:

echo "0" > /proc/sys/net/ipv4/ip_forward

Much better way concering security

Don´t set “net.ipv4.ip_forward=1” inside “/etc/sysctl.conf” and load it instead a (init)script with command:

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

Hint: Check “restore-iptables” and “iptables initscript” below. Make sure to load iptables first!

Iptables:

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 eth0 -o eth1 -m state --state RELATED,ESTABLISHED -j ACCEPT
sudo iptables -A FORWARD -i wlan0 -o eth0 -j ACCEPT
sudo iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT

Block icmp (ping) on eth0:

iptables -A INPUT -i eth0 -p ICMP --icmp-type 8 -j DROP

NAT:

sudo iptables -t nat -A POSTROUTING ! -d 192.168.0.0/16 -o wlan0 -j SNAT --to-source 192.168.1.2
sudo iptables -t nat -A POSTROUTING ! -d 192.168.0.0/16 -o eth1 -j SNAT --to-source 192.168.1.2

Test:

Die Ursache für den Absturz des /dev/ttyUSB* Devices war die zu geringe Stromleistung von 600mA an dem USB-Port. Für die Einwahl wird richtig Saft aus dem USB-Port gezogen. Umgehen kann man das Problem, wenn man in der Datei “/boot/config.txt” einen zusätzlichen Parameter einträgt. Achtung geht nur bei Raspberry PI Modell B+ und PI2 !

Network

Static configuration example.

“wlan0” is primary NIC (also loaded without link on eth0):

auto lo
iface lo inet loopback

auto wlan0
allow-hotplug wlan0
iface wlan0 inet static
        address 192.168.1.77
        netmask 255.255.255.0

        dns-nameservers 192.168.1.1
        #dns-search my-domain.local

Adapter Priority

The priority of networkadapters can be setup/ changed in

/etc/udev/rules.d/70-persistent-net.rules

This file isn´t created on default. To create the file edit:

/lib/udev/rules.d/75-persistent-net-generator.rules

Change

# device name whitelist
KERNEL!="ath*|msh*|ra*|sta*|ctc*|lcs*|hsi*", \
                                       GOTO="persistent_net_generator_end"

to

# device name whitelist
KERNEL!="eth*|ath*|wlan*[0-9]|msh*|ra*|sta*|ctc*|lcs*|hsi*", \
                                        GOTO="persistent_net_generator_end"                                        

The file

/etc/udev/rules.d/70-persistent-net.rules

has been created after a reboot.

WLAN

Scan wlan:

iwlist wlan0 scan

Get wlan-configuration info:

iwconfig

Generate WLAN-Key (to avoid plain-text password):

test@raspberrypi ~ $ wpa_passphrase MY_SSID MY_WPA_KEY
network={
        ssid="MY_SSID"
        #psk="MY_WPA_KEY"
        psk=aebd5aac8952e0ed73f797b9bfe074bcc008e045a5a7028a6dec342f9c
}

Afterwards you have to replace “wpa-psk” within “/etc/network/interfaces”:

wpa-psk "aebd5aac8952e0ed73f797b9bfe074bcc008e045a5a7028a6dec342f9c"

Config-file:

/etc/network/interfaces

Config (DHCP):

auto lo
iface lo inet loopback
iface eth0 inet dhcp

auto wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-ap-scan 1
wpa-scan-ssid 1
wpa-ssid "YOUR-SSID"
wpa-psk "YOUR-PASSWORD"

Config (static):

auto lo

auto wlan0
        allow-hotplug wlan0
        iface wlan0 inet static
        address 192.168.1.X

        gateway 192.168.1.1
        wireless-power off

wpa-scan-ssid 1
wpa-ssid "YOUR-SSID"
wpa-psk "YOUR-PASSWORD"

Power saving

Add

wireless-power off

to

/etc/network/interfaces

and reboot your system.

Check wlan adapter and driver with:

 /sbin/iwconfig
 

and

cat /sys/module/8192cu/parameters/rtw_power_mgnt

Fix problems with power saving for 8192cu wireless chip (e. g. TP-Link TL-WN823N WLAN USB-Adapter Mini , 300Mbit/s, WPS, which is quite fast and recomandable for raspberry pi):

dmesg | grep "usbcore: registered new interface driver*"

Output (or similar):

usbcore: registered new interface driver rtl8192cu

Create a file (containing “8192cu”) such as:

/etc/modprobe.d/8192cu.conf

with following content

# Disable power saving and USB autosuspend
options 8192cu rtw_power_mgnt=0 rtw_enusbss=0

Reboot your system and check settings:

/sbin/iwconfig 
Power Management:off

(W)LAN Adapter check

Cronjob examples:

Example “/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="wlan0 eth1"

Logging

sudo touch /var/log/dhcpd.log

In “/etc/rsyslog.conf” edit as follows:

  *.*;auth,authpriv.none;

to

  *.*;auth,authpriv.none;local7.none -/var/log/syslog

Finally

service isc-dhcp-server restart

Show leases:

cat /var/lib/dhcp/dhcpd.leases

HOSTAPD

Install:

apt-get install hostapd

Start, stop, restart hostapd:

/etc/init.d/hostapd start

Check if interface works in AP mode and which channels:

apt-get install iw
iw list | grep AP
iwlist chan

Conf

Example “/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
#
RUN_DAEMON=yes
DAEMON_CONF="/etc/hostapd/hostapd.conf"
#DAEMON_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=""
