[Q] Ubuntu on Eee Pad, missing eth0

Hello,
I have followed the guides for [DEV] Native Ubuntu and [HowTo] Native Ubuntu as well as searching google and these forums to get ubuntu running on the Asus Eee Pad Transformer. It works brilliantly except for one issue. All of the suggestions I have seen about getting wireless working don't seem to work for me. I feel I'm missing something simple and just need to be pointed in the correct direction. I have a UK version of the Eee Pad.
1. I have made the /etc/wpa_supplicant/wpa_supplicant.conf file as suggested by the forums.
2. sudo ifconfig eth0 down gives "eth0: ERROR while getting interface flags: No such device"
3. /etc/init.d/start-networking doesn't seem to exist on my system.
4. ifconfig only lists lo and usb0. usb0 has an ip address oddly enough.
The list of possible network devices ubuntu says I have are as follows:lo, dummy0, usb0, tunl0, sit0, and ip6tnl0. I have followed various suggestions about bringing down the usb0 interface before working with eth0, but it didn't seem to help.
It makes me think that the wireless drivers are missing in my rootfs.ext2 file, but I'd rather not try to download it again to see due to bandwidth limits. I would appreciate any thoughts or places to go that would help get this working. Thank you for your help.

I've been trying to work through the wireless problem, and I've found a little more info:
Code:
dmesg |grep bcm
device: 'bcm4329_wlan.1': device_add
device: 'bcm4329_rfkill': device_add
bcm4329_rfkill_probe : can't find reset gpio
I think this indicates a problem loading the driver, but I am purely speculating here. I've checked and the chipset's firmware is loaded in /lib/firmware/brcm so the driver is present.
I'll keep playing around to see if I can get it working. Any suggestions that could help point me in the right direction would be appreciated.

Bluetooth DUN on CM 7.1.0

Hi all,
I spent a couple of days Googling around, trying to get Bluetooth DUN working on Cyanogenmod 7.1.0 on my Viewsonic GTablet.
After some hacking around with the source, I got it working. I can connect my GTablet to the internet through my Blackberry Torch on Rogers (in Ontario, Canada).
I've already posted my notes to the CM forums, but apparently since I'm a noob here I can't post the link to it, so here's my notes (direct copied from the CM forums):
Dial-up networking requires the chat binary, which is included in the standard Linux ppp package. For some reason, this binary was omitted from the Android ppp package, so I downloaded the Android 2.3.7 source, copied the chat source in to the Android ppp package and built it from scratch. The instructions for this were found at afewe DOT wordpress DOT com/android-arm-development/use-point-to-point-protocol-ppp-in-android/
Once the chat binary is installed in the proper location on the Android device (/system/bin/chat) it's just a matter of writing a pppd config and chatscript for your given provider. These configs can be found in the berry4all package at berry4all DOT com.
I copied the 'rogers' file from that package and put it in /etc/ppp/peers/rogers, then the rogers-chat file and put it in /etc/ppp/chatscripts/rogers-chat.
I modified the /etc/ppp/peers/rogers so that the last line, which calls the chat binary, reflected the proper locations of the binary and the chat script.
Finally, I removed the 'novj' option from the pppd config. Once the config was all up and ready to go, I went to the terminal and did:
$ su
# rfcomm bind /dev/rfcomm0 <BT MAC> <channel>
# pppd call rogers
And voila! A stable, bluetooth dial-up network connection through my phone.
I just wanted to throw out my notes first to make people aware that its possible and easy. If there's enough interest, I'll write a more detailed and specific step-by-step howto on getting it set up.

Hi,
I see that CM 7.1 includes "bluetooth tether" support now but it's not clear to me what this actually is. Does CM 7.1 include the DUN bluetooth profile? It sounds like you're using reverse tethering, i.e. you are using a Blackberry's data connection so you're using the DUN profile on the Blackberry and are using the CM device as a client?
I have a stock Desire S and am looking for DUN support so I can use the internet access in my car through the Desire's 3G connection. The car supports only DUN and PDANet doesn't work for some reason.
Thanks,
Tim

Looks like you're out of luck.... same story for my Benz with Comand Online Navcom system.
If you drive an MB like me, you'll have to wait for an update later this year (from MB that is)... or buy a BlackBerry.

From the press release:
"An option for customers having phones without DUN support is the Mercedes-Benz “Bluetooth (SAP) telephone module - V4″, available early 2012. The new version (V4) offers UMTS capability, allowing fast data connection using customer SIM card or accessing SIM information from SAP (SIM Access Profile) enabled mobile phone."
and:
"... Furthermore Mercedes-Benz is in close talks with leading Android phone vendors to enable the DUN feature in their phones by default."
(I have Android 2.3 and Windows Phone 7.5 devices)

Yes, so we can pay £400 for a SAP module or buy a new phone if anyone actually launches an Android handset with DUN - remembering that Google appear to have zero interest so it will be manufacturer specific. Oh yes, I nearly forgot - Android doesn't have SAP profile support either!
I'd say the chances of Mercedes updating existing systems to work with phones which don't support DUN is virtually zero. Hardly ideal on a system which cost £2000...
Cheers,
Tim

I agree. It was a huge mistake of MB to go with this dead BT DUN protocol!

I thought Android phones do support SAP, isn't that why the car can dial a contact?

'fraid not, that uses PBAP (phone book access protocol).

Complete WiFi UI - Solved

I am starting this thread because i found that after all this long time of waiting an improvement from Android guys from Google regarding a complete UI for connecting to the miscellaneous WiFi configurations nothing comes out.
I consider my thread android development related, but if the mods want to move it please do it.
I am not a developer but I'm a user which wants all the cake not just a bite.
I am referring to special type of WiFi connections which wpa_supplicant is capable like:
"
EAP-TLS
EAP-PEAP/MSCHAPv2 (both PEAPv0 and PEAPv1)
EAP-PEAP/TLS (both PEAPv0 and PEAPv1)
EAP-PEAP/GTC (both PEAPv0 and PEAPv1)
EAP-PEAP/OTP (both PEAPv0 and PEAPv1)
EAP-PEAP/MD5-Challenge (both PEAPv0 and PEAPv1)
EAP-TTLS/EAP-MD5-Challenge
EAP-TTLS/EAP-GTC
EAP-TTLS/EAP-OTP
EAP-TTLS/EAP-MSCHAPv2
EAP-TTLS/EAP-TLS
EAP-TTLS/MSCHAPv2
EAP-TTLS/MSCHAP
EAP-TTLS/PAP
EAP-TTLS/CHAP
EAP-SIM
EAP-AKA
EAP-AKA'
EAP-PSK
EAP-FAST
EAP-PAX
EAP-SAKE
EAP-IKEv2
EAP-GPSK
LEAP (note: requires special support from the driver)"
This is copied from here http://hostap.epitest.fi/wpa_supplicant/
Seems that we have the gun and the bullets but we don't have the trigger.
This idea come to me when i was struggling connecting to my work WiFi and never succeeded, phones like Symbian or Windows based laughed into my phone's face (and i think that is not correct, considering it frustrating).
My proposal to all the devs from XDA is to build a new app and wpa_supplicant with all drivers and stuff which will be able to help us connecting very easy to all kind of WiFi methods.
PS: My work network configuration for windows is like this:
SSID, CKIP LEAP, username, domain, password.
Hidden WiFi: http://code.google.com/p/android/issues/detail?id=1041
LEAP WiFi: http://code.google.com/p/android/issues/detail?id=1871 ; http://code.google.com/p/android/issues/detail?id=1386
Ad-Hoc WiFi: http://code.google.com/p/android/issues/detail?id=82
Devices that are capable to connect on my work WiFi network:
Symbian V3 (Nokia N8)
Windows Mobile 6.5 (HTC Diamond)
Devices that are not capable to connect on my work WiFi network:
Android (HTC Desire HD and Samsung Galaxy S I)
iOS 4 (iPhone 3Gs)
iOS 5 (iPod)
Blackbery (Curve 8900)
============================================================
Update: 29/11/2011
After a 2-3 weeks of Google-ing I think that i found the gap with LEAP:
How you can see above LEAP - requires special support from the driver and i found a Linux driver which says like this:
2086 // CCX 1 spec v1.13, A01.1 CKIP Negotiation (page23):
2087 // "A Cisco access point advertises support for CKIP in beacon and probe response packets,
2088 // by adding an Aironet element and setting one or both of the CKIP negotiation bits."
2089 if( (info_element->data[IE_CISCO_FLAG_POSITION]&SUPPORT_CKIP_MIC) ||
2090 (info_element->data[IE_CISCO_FLAG_POSITION]&SUPPORT_CKIP_PK) )
Source:http://lxr.free-electrons.com/source/drivers/staging/rtl8192e/ieee80211/ieee80211_rx.c
My work WiFi require CKIP Encryption so this is root cause for me to not be able to connect to LEAP.
Currently broadcom support: 802.1x; WEP, WEP2, WPA, WPA2 (Personal) TKIP and AES hardware acceleration 802.11i. When "broadcom" will release compatible drivers, we will be able to connect. Until then, all users that are in my situation will better get an alternative.
http://pdf.eccn.com/pdfs/Datasheets/Broadcom/BCM4329.pdf
http://os1a.cs.columbia.edu/lxr/source/drivers/net/wireless/bcm4329/wl_iw.c
So next remaining thing will be a "Complete UI" release for android which offers all type of connections.
================================================================================================
Update: 07/12/2011
In my craziness to find a solution to my problem regarding connection to work corporate WiFi, I found the missing link (in my opinion) between android and Linux capability to access CKIP encrypted networks: http://o2droid.phj.hu/trac/browser/kern_oII/drivers/staging/rt2860/sta/assoc.c . It is about a special characteristic that allow connections to Aironet access points with CCX (CISCO Compatible Extensions).
================================================================================================

I need a port from Dell Streak to HTC DHD
I searched Google again and i found this:
http://forum.xda-developers.com/show...62&postcount=1 here is a file listed "system/etc/wlan/sdio-g-cdc-reclaim-idsup-wme-pktfilter-keepalive-aoe-toe-ccx-wapi.bin" and with a F3 in Total Commander contain this:
"NONE WEP1 TKIP WEP128 AES_CCM AES_OCB_MSDU AES_OCB_MPDU CKIP CKIP_MMH WEP_MMH" and
"ccx_auth_mode"
The file is in the Streaksmi.zip which is miui for dell streak that has bcm4325 chipset.

So what is different between MIUI and a usual Android system?

No idea apart from that it keeps the individual settings separately so you don't have to input manually every time you need to change, but it seems to be the only thing that works for all the networks I use.

Is it capable to connect with Ad-Hoc type of networks too?
And the answer is "Yes", wpa_supplicant from MIUI is capable to connect to Ad-Hoc networks.

Not sure what your problem connecting might be. At uni, we have EAP-PEAP/MSCHAPv2, and I can connect fine, and connect any android phones that come in fine aswell. We use a program called xpressconnect, but can do it manually too.

I have an application on my laptop that makes a network from it (like a router) which I've always assumed used ad-hoc and it's always connected fine to that so yeah I assume so =)
Old Leedroid ROMs used to work too if you wanted sense, but they were back in August-ish time

Already tried manual config

Before i start this thread i tried several combination of configurations, I buyed even Advanced Leap WiFi from market and nothing. This problem is not from configuration because, like I said windows mobile and symbian is piece of cake to connect.
My connection is hidden ssid. After I put my credentials configured with leap, another network with same name but with WEP security appears, saying connecting...disconnected.

Update
I just tried MIUI and conclusions are:
1) Ad-Hoc is connectible (but stock android with a modified(patched) wpa_supplicant is capable to connect to Ad-Hoc too).
2) LEAP is still doing Connecting....Disconnected.
3) MIUI has a file named "/system/bin/wpa_cli" which stock didn't have it.

For number 2 try manually inputting a static ip, dns, gateway and netmask =)

Thanks for the tip, I will try tomorrow. But what is the catch? What makes WM and Symbian better than Android when is about connecting to a LEAP network?

So you'd like other people to build an app for you?

Why do you say "YOU"? Is not just me, is the whole android community that has lack of what i said in the thread. The work that will be done by a skilled developer from here will be used in the future by all androiders.
All the info and opinions that will be wrote in here will help the "courageous developer" to build the Complete WiFi UI.
My experience with the WiFi will help others to connect on similar networks.
In my opinion this is true development: trying to reach the impossible, or not yet possible, or not yet known.
I think is at last 1 developer in here which knows very good the WiFi protocols and can give us a hint.
For us (the ordinary users) is very difficult to start now learn coding in android and network protocols, because will last at least six months of staying in codes to get the idea of coding.

I checked your thread and is says nothing about compiling in Android OS. In my opinion this is the root cause of not fully working WiFi connectivity. With a proper .conf file of latest wpa_supplicant i think that the issue will become history.

[Q] securing tablet for general public

Hi all,
I make a application android for my customers but my customers want to allow their customers access to tablet with my application "blocked". The final user can't quit my application, he can simply use my application.
Tablet must have ethernet (via usb to lan adapter), the bottom button bar must be hidden.
Can you recommend me a model ?
Thanks a lot,

I have tested the Toshiba folio 100, but with no driver video for the graphic card with andro 3.0.
Andro 3.0 is required for the usb to lan adaptater

I have try too the acer iconia a200, but isn't rootable for the moment,
now I try the samsung galaxy tab

hi Alexandre,
we have the same problem for a new project.
Do you think it's possible do do it without rooting the device ?

Hi,
may be if you wantt stay in dhcp and if you have usb lan driver in your os.
Thanks,

Lenovo thinkpad offers alot of security for the tablet and is integrated into the framework and not a app alone, which makes breaking the security alot harder for regular users even with root enabled.
i think its a question of users/companies wanting security they get Thinkpad tablet for that, which cisco client included for vpn as well.

Hi dexter,
Do you test this tablet?
Do you think it's possible to wake up this tablet automaticaly the morming? by a magic packet or a rtc alarm?
Thanks,

Hi Alexandre17220,
I think we are working on similar projects because it seems we have tested the same tablet and we are also lookgin for the followinf important things :
-A- securing the environnement by prohibiting the user to access the Os interface
-B- use a ethernet device via an USB adapter.
We have tested the following ones :
- Toshiba Folio 100 (ok for point A & B but not enough tested on HC 3.2)
- Acer Iconia A200 (the european tablet seems to be not rootable yet)
- Samsung Galaxy Tab P7510 (rootable without any problem so point A must "workable", but we habe problems with point B : do you connect your Tab with Ethernet ?)
Regards,
André

Hi André,
The samsung galaxy is very good, I have rooted it via this link http://galaxytabhacks.com/galaxy-tab-10-1-hacks/how-to-root-galaxy-tab-10-1-the-easy-way/
Yes my application dialog with a server via http request. So I don't want use wifi because it's slow and very limited.
If you want to hide the bottom bar you can use this code :
Code:
try {
Process myproc = Runtime.getRuntime().exec(new String[]{"su","-c","service call activity 79 s16 com.android.systemui"});
myproc.waitFor();
} catch (Exception e) {
Toast.makeText(this, "impossible to kill the bottom bar", Toast.LENGTH_SHORT).show();
}
Thanks,

i tested the firmware on my acer a500, but not the physical lenovo hardware, but thats not important here.
and since wifi is going offline during deepsleep on tegra2 tablet, i doubt any magic packet can awaken any tegra tablet unless you force wifi always on, but then alot of angry users will complain about battery life.

[App] DHCPv6 Client

Hi everyone,
What is this?
This is a DHCPv6 Client for Android.
Motivation
Google doesn't support DHCPv6. See: https://code.google.com/p/android/issues/detail?id=32621
This is an issue for a lot of people especially for corporations and universities because they need control over the IPv6 addresses they distribute.
I did some research and found out that Fairphone already has support for DHCPv6, they achieve this by implementing the wide-dhcpv6 client and added some own scripts around it.
This gave me the idea to play a little with this client. I did so and the result is this app.
Basically it is an implementation of Fairphone's DHCPv6 solution for every rooted Android phone and not just Fairphone.
Workflow
Broadcast Receiver for CONNECTIVITY_CHANGE (invoked when connectivity is changed)
Check if /system/bin/dhcp6c <interface> is running (this is the master process) if not then invoke it
Sending a signal with /system/bin/dhcp6ctl to the master process to get an IPv6 address (dhcp6ctl -C start interface <interface>)
Why is root required?
Root permissions are required for the DHCPv6 client to work because it binds to port 546.
Permissions
root - see above
access network and wifi state - catching network changes
internet - for checking if internet is available and getting a list of all interfaces available
billing - for donation
Get the app
Simply download it from the app store: Download from Google Play Store
Source Code
DHCPv6 Client for Android on GitHub
-realm_01

hostname/domain name support?
Installed this on my android TV media box, and it now connects to my DHCPv6 server as expected, and a lease is registered, however it does not supply a host name or domain name. The domain name is advertised by my router, and also supplied as option in DHCPv6 scope.
Are these an android problem, or the DHCPv6 client?

Almost working...
Hi !
Thanks for the app. Android really needs this. I'm trying to use it on Motorola XT1058 running Lollipop. I can see in the packet capture of my router (OpenWrt) that the DHCPv6 transaction is working and my router is giving out statefully assigned IPv6 addresses to my phone. Unfortunately, these addresses don't get assigned to wlan0 interface on Android. I'm still seeing only stateless addresses on wlan0. Any help would be appreciated.
Regards,
André

Thank you, as a system administrator it was crazy annoying to not be able to enforce a an IPv6 range for android devices

This app doesn't work until I adb shell into my device and run dhcp6c wlan0 as root manually.

Works on Pixel XL
Works fine on my Pixel XL with Android 7.1.
Thank you!

Hi, great job on this app. Wondering how you were able to override the Android DHCP software from trying to connect to networks and have it use the IPV6 info your client acquired?
