STEP BY STEP SETTING 3G MULTIWAN DI OPENWRT
by Obengkumana

PERALATAN TEMPUR

- ROUTER YG ANE GUNAKAN ADALAH HUAWEI HG553

- MODEM YG ANE GUNAKAN ADALAH VODAFONE/HUAWEI K3715& HUAWEI E153
- KARTU YG DIGUNAKAN KEDUANYA T******EL F***H
- USB HUB abal2 kisran harga 10-15rb emoticon-Hammer (S)

(kabel sudah diganti untuk menghindari daya yg kurang pada USB HUB, sehingga tidak perlu mempergunakan adaptor untuk menambah daya di USB HUB emoticon-Smilie

)

ane yakin bs juga di terapkan pada semua roter dengan syarat
1. firmware yg digunakan openwrt
2. ada slot USB dengan USB HUB
3. 2 modem bs langsung terdeteksi dengan baik tanpa perintah tambahan.

langsung aja ya tanpa basa basi

PERSIAPAN
- back up dulu firmware/config yg ada sekarang, menghindari gagal setting
- makanan ringan dan air secukupnya emoticon-Ngakak (S)

- jika anda seorang AHLI HISAP, pesiapkan min 2 bungkus dan segelas kopi hangat untuk melunturkan nikotin emoticon-Hammer (S)

TAHAP KE LIMA

masuk ke "putty"

- Buat file, dengan perintah:

Quote:

# touch /bin/tester.sh
# chmod 755 /bin/tester.sh

- copas tulisan di bawah ini ke dalam file /bin/tester.sh

Quote:

Spoiler for tester.sh:

#!/bin/sh
if ! ping -q -c 1 -W 10 -I 3g-wan 8.8.8.8 > /dev/null; then
(ifup wan; sleep 5; /etc/init.d/multiwan restart) &
fi

if ! ping -q -c 1 -W 10 -I 3g-wan2 8.8.8.8 > /dev/null; then
(ifup wan2; sleep 5; /etc/init.d/multiwan restart) &
fi

kembali masuk ke "putty"

- ketik perintah:

Quote:

# /etc/init.d/cron stop
# echo "*/2 * * * * /bin/tester.sh" >> /etc/crontabs/root
# /etc/init.d/cron enable
# /etc/init.d/cron start

SELESAI...............

* silahkan ubah config di atas sesuaikan dengan jenis roter, ISP yg dpergunakan dan posisi terdeteksinya modem di router
