Данный способ позволяет выходить в Internet через notebook (проверялось с Windows 7).


Что необходимо:
1. Установить последнее ядро LK2.xx
2. Установить и один раз запустить (нужны исполняемые файлы) WiFi tether
3.1 Ручная установка:
- Качаем архив: ad-hoc.7z, распаковываем
- Далее через adb

adb shell remount rw
adb push set-adhoc /system/xbin/
adb push start-adhoc /system/xbin/
adb push off-adhoc /system/xbin/
adb shell chmod 0755 /system/xbin/set-adhoc
adb shell chmod 0755 /system/xbin/start-adhoc
adb shell chmod 0755 /system/xbin/off-adhoc
adb shell remount ro

3.2 Через Recovery
- Качаем: i5700_AdHoc_update.zip и кладем в корень SD
- Далее Recovery -> apply any zip -> i5700_AdHoc_update.zip


Как используем (пока полуручной режим, может кто напишет оболочку):
1. Идем в свою ОС (на примере Windows 7)
- Предоставляем доступ к Интернету по локалке через беспроводное соединение


2. Запускаем терминал на Спике и вводим

set-adhoc

3. Идем в Windows ищем в WiFi сетях SpicaAdHoc и подключаемся
4. В терминале на Спике вводим

start-adhoc

5. Убеждаемся, что для Спики выделился IP адрес, что-то типа

eth0: leased 192.168.137.63 for 604800 seconds

все, чтобы вообще не использовать GRSP/EDGE/3G соединение можно вырубить интерфейс

ifconfig pdp0 down

Как выключить:
1. Выключаем Ad-Hoc WiFi

off-adhoc

2. Если вырубали pdp0, то

ifconfig pdp0 up

Небольшое замечание!!!
Чаще всего после этих манипуляций 3G не поднимается, помогает выкл/вкл Airplan mode или перегрузить Спику.

WARNING: THIS METHOD CAN BE DANGEROUSE. DO NOTHING IF YOU DO NOT KNOW WHAT YOU DO.
I CAN'T BE RESPONSIBLE IF YOU TRANSFORM YOUR SPICA LIKE A BRICK


You can enter into Internet via your notebook


You need:
1. Install last kernel LK2.xx
2. Install and run onceWiFi tether
3.1 Install by adb:
- Download: ad-hoc.7z, unpack
- using adb

adb shell remount rw
adb push set-adhoc /system/xbin/
adb push start-adhoc /system/xbin/
adb push off-adhoc /system/xbin/
adb shell chmod 0755 /system/xbin/set-adhoc
adb shell chmod 0755 /system/xbin/start-adhoc
adb shell chmod 0755 /system/xbin/off-adhoc
adb shell remount ro

3.2 By Recovery
- Download: i5700_AdHoc_update.zip and put on SD
- Recovery -> apply any zip -> i5700_AdHoc_update.zip


How to use scripts:
1. On your OS (example, Windows 7) shere netwroke connection
2. Run terminal on Spica

set-adhoc

3. In Windows connect to SpicaAdHoc WiFi network
4. In terminal (Spica) enter

start-adhoc

5. We will get IP address from Windows something

eth0: leased 192.168.137.63 for 604800 seconds

Ok
if you want turn off 3G, you can

ifconfig pdp0 down

How off:
1. Turn off Ad-Hoc WiFi

off-adhoc

2. And up 3G

ifconfig pdp0 up

A short note!
Most often, after these manipulations 3G does not rise, helped off / on Airplan mode or reboot Speke.

Thanks LeshaK this works great, i can finally use my computer's connection using just a WiFi adapter and no router.

I did have to run

off-adhoc
start-adhoc

twice before it started but after that it worked without problems. The first time it gave some errors about eth0 not being found, second time it didn't give this errors.


Now I'm trying to achieve the same but with a secured connection (WEP or WPA) so that my ad-hoc connection is not accessible by other people.

From what i've read on the net, using iwconfig only WEP can be used, to use WPA i should use wpa_supplicant.
I haven't gotten it to work yet, but I'll report back if i manage to get this to work.
If anybody has any info about WEP/WPA I'd like to hear about it.

No secure for this ad-hoc scripts

how to set dns?

[LeshaK]

It's automatically installed in the scripts

setprop net.eth0.dns1 8.8.8.8
setprop net.eth0.dns2 8.8.4.4

[indraf]

yes i have checked that in start-adhoc file
but i still can not online, ping: unknown host google.com
i can ping my laptop and spica able to ping laptop
did i miss something?

[LeshaK]

May be firewall on notebook?

[indraf]

no, it's working on my nokia
did you use static or dhcp on notebook? i have tried both and no luck
is it because i'm using windows xp?

log:

# set-adhoc

# start-adhoc
Query ip address...
eth0: dhcpd 4.0.1 starting
eth0: host does not support a monotonic clock - timing can skew
eth0: broadcasting for a lease
eth0: timed out
eth0: probing for an IPV4LL address
eth0: checking 169.254.77.139 is available on attached networkd
eth0: using IPv4LL address 169.254.77.139
Set DNS servers...
We are ready

[LeshaK]

I use dhcp to get IP for Spica

eth0: broadcasting for a lease
eth0: timed out
eth0: probing for an IPV4LL address

but your i5700 didn't get IP

[indraf]

okay, but if i ping it to 169.254.77.139 from notebook, i got replied from spica.
i'll try in windows7 then... just to make sure
