Category: HowTo(s)

Let’s Get It Started:

Prerequisites:

• Download Raspbian for Raspberry Pi
• Installing operating system images – Raspberry Pi Documentation

• INTERFACES(5) – /etc/network/interfaces – network interface configuration for ifup and ifdown

$ cat /etc/network/interfaces.d/wlan0 
iface wlan0 inet static
 address 172.31.31.172
 netmask 255.255.255.0
$

• ref: Private network – Wikipedia
• DNSMASQ(8) – dnsmasq – A lightweight DHCP and caching DNS server.

$ sudo apt-get -qq update && apt-get -qq install dnsmasq
$ cat /etc/dnsmasq.d/dhcp-range 
dhcp-range=172.31.31.177,172.31.31.199,12h
$ sudo systemctl restart dnsmasq
$ sudo systemctl status dnsmasq
$

• HOSTAPD(8) – hostapd – IEEE 802.11 AP, IEEE 802.1X/WPA/WPA2/EAP/RADIUS Authenticator

$ sudo apt-get -qq update && apt-get -qq install hostapd
$ sudo gzip --stdout --decompress /usr/share/doc/hostapd/examples/hostapd.conf.gz > /etc/hostapd/hostapd.conf
$ sudo sed --in-place 's|DAEMON_CONF=|DAEMON_CONF=/etc/hostapd/hostapd.conf|' /etc/hostapd/hostapd.conf
$ sudo editor /etc/hostapd/hostapd.conf
$ sudo systemctl daemon-reload
$ sudo systemctl restart hostapd
$ sudo systemctl status hostapd
$

• IPTABLES(8) – iptables/ip6tables — administration tool for IPv4/IPv6 packet filtering and NAT

iptables --table nat --append POSTROUTING --out-interface wlan0 --jump MASQUERADE

• SYSCTL(8) – sysctl – configure kernel parameters at runtime

$ sysctl net.ipv4.ip_forward
net.ipv4.ip_forward = 1
$

mount unknown filesystem type ‘exfat’

pi@igla:~ $ sudo apt-get -qq update
pi@igla:~ $ sudo apt-get -qq install exfat-fuse

Voilà!

simply use /dev/rdiskX instead of /dev/diskX, like following:

$ time sudo dd if=~/Downloads/kali-2.1.2-rpi2.img of=/dev/rdisk2 bs=1m

sys 0m5.829s
$

… about ~7G in ~7min, not bad huh?)

root@457165ff1c3e:/# cat /etc/logstash/conf.d/* | grep -v \#

input {
gelf { codec => “json” }
}

filter {
json {
source => “message”
}
}

output {
elasticsearch { hosts => [“0:9200”] }
}

• REQ: elk-docker
  • Building the image
    • EXPOSE (incoming ports)

search and replace:

$ grep --after-context=3 ports docker-compose.yml
ports:
- "5601:5601"
- "9200:9200"
- "5044:5044"
$


&

$ grep --after-context=3 expose docker-compose.override.yml
expose:
- "5601"
- "9200"
- "5044"
