[RPI] Static Address Raspberry Pi

21 Maret 2015

static eth0

Intro::

Disaat mau ngoprek Rpi via ssh gak nyaut, disitu IP Rpi berubah. Jadi untuk mengatasi perubahan IP digunakan metode static ip.

Gather Information::

- ifconfig eth0 *cek IP pada metwork module eth0
catat addr, bcast, mask

address 192.168.1.136
broadcast 192.168.1.255
netmask 255.255.255.0

- netstat -nr *cek akan route kemana
catat gateway, destination untuk network eth0

Gateway 192.168.1.1
Destination 192.168.1.0

- sudo nano /etc/network/interface *rubah default setting
ganti

iface eth0 inet dhcp -> iface eth0 inet static

tambahkan dibawahnya

address 192.168.1.136
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1

- sudo reboot *restart

[RPI] Wifi dengan Raspberry (updated)

16 Maret 2015

pulang kerja adalah waktu paling tepat untuk ngoprek, terbukti 1st try http://t.co/sPioA9MEJT pic.twitter.com/nFOa5ZDcfF
— Faris Widyantho (@radenfaris) March 16, 2015

Intro::

Koneksi PI dengan Wifi dongle. Kebetulan dongle yang ku punya TP-LINK TL-WN727N (firnware-ralink) sudah include dalam RASPBIAN.

Driver Wifi::

- lsusb *pengecekan usb terdeteksi/tidak
- sudo apt-get install firmware-ralink *installasi driver
- sudo iwlist wlan0 scan *pengetesan scanning wifi dengan dongle
- sudo nano /etc/wpa_supplicant/wpa_supplicant.conf *pembuatan konfigurasi wifi yang ingin disambung

network={

ssid="SSID"

psk="PASSWORD"

}

- sudo ifdown wlan0 *reset dongle dengan mematikan kemudian menghidupkan
- sudo ifup wlan0
- ifconfig wlan0 *jika tersambung cek ip dengan ifconfig

Update auto connect (21 June 2015)
- sudo nano /etc/network/interfaces edit config untuk auto connect wlan

auto lo
iface lo inet loopback

auto eth0
allow-hotplug eth0
iface eth0 inet dhcp

auto wlan0
allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp

[RPI] Raspberry 3G

15 Maret 2015

sakis3g interface

Intro::

Koneksi 3G di Raspberry dengan Huawei E303. Menggunakan usb-modeswitch, ppp, dan sakis3g.

Driver Modem::

Connect via SSH

- Sambung Modem dengan Raspi

- ketik lsusb di LX-Terminal untuk melihat apakah modem terdeteksi/tidak

pi@raspberrypi ~ $ lsusb
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.
Bus 001 Device 006: ID 12d1:1446 Huawei Technologies Co., Ltd. E1552/E1800/E173 (HSPA modem)

- sudo apt-get update
- sudo apt-get upgrade
- sudo apt-get install usb-modeswitch *untuk merubah dari mode storage menjadi modem
>> kalau sudah reboot dan dicek lsusb akan berubah menjadi seperti ini

pi@raspberrypi ~ $ lsusb
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.
Bus 001 Device 006: ID 12d1:1436 Huawei Technologies Co., Ltd.

- sudo apt-get install ppp *modem dial up 3G menggunakan protokol ppp
- Install sakis3g dari mirror (karena sakis3g down)

> sudo wget "http://downloads.sourceforge.net/project/vim-n4n0/sakis3g.tar.gz?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fvim-n4n0%2Ffiles%2F&ts=1363537696&use_mirror=tene~t" -O sakis3g.tar.gz
> sudo tar -xzvf sakis3g.tar.gz> sudo chmod +x sakis3g

- sudo ./sakis3g --interactive *buka jendela sakis3g
- Connect with 3G
- USB device *pilih koneksi via
- Huawei Mobile *pilih modem
- pilih Interface #0
- Reported by your modem (Internet)
- isi username: internet
- kemudian password: internet
- jika lampu indikator modem menyala dan panel sudah connected, selamat sudah tersambung
- cek dengan mengirimkan paket ping ke google sebanyak 4 ping -c 4 google.com

Catatan:

- setelah connect dan disconnect internet dengan 3G, tidak bisa kembali menggunakan koneksi internet dari LAN kecuali setelah reboot

[RPI] Connect Pi via SSH dan Remote Desktop VNC

14 Maret 2015

Remote Desktop via VNC

Intro::

Koneksi SSH sudah aktif by default di RASPBIAN jadi tak perlu disetting lagi.

Timeline::

1. Connect via SSH RASPBIAN OS
Material
- Raspberry Pi 2 & Power supply
- Cable LAN Straight
- Router
- Keyboard & Mouse
- HDMI to VGA converter
- Monitor

Software
- SSH Client (cth: di Windows - Bitvise Tunniler)
- VNC Client (cth: di Windows - Tight VNC)

SSH Connection::

Connect via SSH

- Boot sampai Desktop Raspbian dan sambung cable LAN

- cari tahu IP Raspbian dengan mengetikan ifconfig di LX-Terminal

- Install Bitvise Tunniler di Windows

- Masukan IP Raspbian dengan port 22

- Initial Method = Password

- default Username/Password Raspbian::

username : pi
password : raspberry

- click connect, dan save session.

- open New Terminal Console untuk membuka console

selamat malam minggu, malam ini ngetes uik uik si manis via secure shell pic.twitter.com/EcPsefp0vC

VNC Connection::

agak tricky remote vnc, masukin port 5901, kalo nggak nanti keluarnya "target machine refused actively" pic.twitter.com/AnZNC06kFX
— Faris Widyantho (@radenfaris) March 14, 2015

Connect via SSH/Boot langsung
- LX-Terminal
- sudo apt-get update
- sudo apt-get upgrade
- sudo apt-get install tightvncserver
- vncserver :1 *jalankan vncserver port 1
- untuk pertama kali akan diminta masukan password untuk authentication *raspberry
- VNC sudah run

Membuat shell script untuk menghidupkan VNC
- sudo nano vnc.sh *membuat file vnc.sh
- tulis shell script ini

#!/bin/sh
vncserver :1 -geometry 1024x768 -depth 24 -dpi 96

- simpan ctrl+o, exit ctrl+x
- ubah permission sudo chmod 755 vnc.sh
- panggil dengan ./vnc.sh

Catatan:

- :1 dalam vncserver adalah port 1, di VNC client masukan port 5901
- resolusi/ -geometry dapat dirubah sesuai kebutuhan
- gunakan text editor nano / vi untuk membuat shell script
- ubah permission chmod untuk dapat dieksekusi
