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
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
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 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

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 !

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
network 192.168.1.0
broadcast 192.168.1.255
#gateway 192.168.1.1
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 192.168.1.1
#wpa-ap-scan 1
#wpa-scan-ssid 1
wpa-ssid "ssid_name"
wpa-psk "password"
auto eth0
iface eth0 inet static
#iface eth0 inet dhcp
address 192.168.1.66
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 192.168.1.1
#dns-search my-domain.local
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.
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
iface lo inet loopback
auto wlan0
allow-hotplug wlan0
iface wlan0 inet static
address 192.168.1.X
netmask 255.255.255.0

#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"
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
Edit
/boot/config.txt
or
/boot/firmware/config.txt #on newer raspis such as raspi 4
and add:
[all] # turn wifi and bluetooth off dtoverlay=pi3-disable-wifi dtoverlay=pi3-disable-bt
or
[all] # turn wifi and bluetooth off dtoverlay=disable-wifi dtoverlay=disable-bt
on Rapberry Pi 4.

# 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=""

Convert file “testvideo.h264” to *.mp4:
sudo apt-get update sudo apt-get install gpac
MP4Box -add testvideo.h264 testvideo.mp4
To disable the raspi-cam LED edit “/boot/config.txt”:
disable_camera_led=1
Enable raspicam, if you get “Failed to open video device /dev/video0: No such file or directory” in motion:
echo "bcm2835-v4l2" | tee -a /etc/modules sudo modprobe bcm2835-v4l2
