[DEV] Solve VPN PPTP connection Problems. Kernel developers please help! - Optimus One, P500 Android Development

I'm trying to connect to our companies network through a VPN PPTP connection. The connection does not work and this is what I can see with logcat:
Code:
D/VpnService(26589): VPN UP: down
I/SProxy_mtpd(26589): Start VPN daemon: mtpd
D/SProxy_mtpd(26589): mtpd is running after 0 msec
D/SProxy_mtpd(26589): service not yet listen()ing; try again
D/mtpd (26960): Waiting for control socket
D/mtpd (26960): Received 20 arguments
I/mtpd (26960): Using protocol pptp
I/mtpd (26960): Connecting to xxx.xxx.xxx.xxx port 1723
I/SProxy_mtpd(26589): got data from control socket: 20
I/mtpd (26960): Connection established (socket = 12)
D/mtpd (26960): Sending SCCRQ
D/mtpd (26960): Received SCCRP -> Sending OCRQ (local = 50624)
I/mtpd (26960): Tunnel established
D/mtpd (26960): Received OCRQ (remote = 0)
I/mtpd (26960): Session established
I/mtpd (26960): Creating PPPoX socket
F/mtpd (26960): Socket() Address family not supported by protocol
So as you can see the tunnel works but the problem is with the socket() call returning an error.
The problem is here in pptp.c line 238 I think.
Can any kernel developer help? Perhaps this is only a kernel configuration issue because standard HTC Desire and Motorola Droid seem to work without problem.
I have tested it on the P500 with stock kernel, drellisdee kernel and Der_Caveman kernel. Always the same problem.

Have you tried OpenVPN from Market?
You'll need root and busybox.

OpenVPN does not use PPTP. This will not work in my case.

You should try ROM Prime!
I have the same problem like you. Only Prime Rom can solve this, I think the problem is the version, Prime uses 2.2.1, others use 2.2!

Hmm, 2.2.1 uses a different kernel. Perhaps we have to check kernel configs of both versions.

Wlan suddenly stopped working.

Hi.
Ive been using cyanogenmod since i got my nexus.
Been running gr8. No problems what so ever.
Now however my wlan suddenly decided to be unavailable.
I was running CM5.0.6 + DesireCamera OC/UV kernel.
Symptoms: When enabling Wifi i get no Icon and if i scan for networks I see no networks.
What ive tried so far without luck in order.
Reflash cm 5.0.6. <- multiple times
reflash desirecam <- multiple times
push bcm4329.ko <- multiple times
wiped all and
Kang-o-rama 0.6
Edit
Just tried reflashing radio and then pushing bcm4329.ko.
still no go
And it still isnt working
Am i missing something ?
Heres what i got from lolcat.

[Q] Socket() Address family not supported by protocol

Hey has anyone tried connecting to a windows VPN using PPTP on Galaxy S I9003 (android 2.2.1) and not suceeding?
I've traced the problem down to this log:

.
which is the source of the problem, does anyone have any idea what can be done to fix it?
In a dark back alley of my mind, there's a memory of a tweak at least in the speedmod kernel. It's about VPN or something else about networks.
I don't know whether the kernel is even compatible but maybe reading up on that can give you some more information.
good luck
A lot can go wrong with VPN.. can you access it from pc?
I'm seeing this as well. Trying to connect to StrongVPN from CM7-03232011-nightly. I can connect to this VPN with Windows and Linux.
Thanks man, I'm now tryin' to figure out the compatibility issues

@Auzy:
I can connect through PC. This log snippet confirms that something is missing in socket framework of this firmware. Moreover, a friend of mine has Galaxy S I9003 and I did the same procedure on his phone and the log shows smooth progress of the same VPN host, so there is something wrong inside and I'm trying to dig it. Since the phone is released pretty recently, there are few resources which can be relied upon. Even CWM does not support this phone yet.
Having the same problem.
Hamid, I guess you are from Iran like me. It must be a problem with middle eastern firmwares because I don't see anyone else complaining.
I took my phone to ParsMicrotel guarantee services and they couldn't help.
Did you had any luck solving this problem?
I don't know if it's just the Middle-East firmwares or not. I live in Kuwait, and I had the same problem with the stock Middle-East firmware that came on the phone, so I flashed one of the other ROMs available from samfirware.com , I9003XWKB1, and got the same result. Since the phone was new I completely wiped the phone before and after the firmware upgrade. I still had the same problem. So then I tried the newest European ROM, I9003XXKB3. Again, wiped the phone before and after the flash, as well as cleared the dalvik cache...........same problem. I have tried connecting via 3G as well as Wi-fi with no luck. I know it's not the ISP since I can connect using my computer, even when using the i9003 as a mobile AP. Also, a co-worker of mine has the i9000 on the same network and I am able to connect to the VPN on his phone using either PPTP or L2TP/IPSec PSK VPN. I think it may be something with either the phone hardware, or maybe a bug in the phone baseband software.
Has anyone been able to connect to any type of VPN using the i9003?

VPN problems

I have some problems using VPN on Gingerbread.
I upgraded my I9000 to a stock JVO with CF root. Now I noticed that I can no longer connect successfully to my VPN server. Before I was using I9000XXJPY and was working, but now it starts to connect and just stay with "Connecting..." for about 1min then drops.
Because I have access on the VPN server I can see the auth going ok and the VPN tunnel going up. I can even ping for couple of sec the VPN IP.

Nobody using VPN in Gingerbread? Any feedback would be appreciated.
rising the stakes
Ok, since nobody rush here, I will raise the stakes:
Who can help me to find a fix for this problem will win a 3 month VPN account to a VPN provider of my choice (lots of servers to use there).
If anyone have a android setup close to mine and it's VPN works, let me know.
Have u tried any other kernel or turning VPN encryption off. Also try 1Vpn app from the market
Sent from my GT-I9000 using XDA Premium App
Did you turn encryption OFF (uncheck) on your phone?
AFAIK, there is no mppe encryption support in the stock android firmware. Maybe your previous firmware included the module? Anyway, PPTP works fine for me with MPPE disabled, but not if I require it. Hope this helps...
I do get the same behavior with or without the mppe enabled. It doesn't looks like to be a encryption problem as I can see the log in successful on the server and even can ping the client IP after for couple of seconds. It looks like the VpnService does not see the connection being established and it just stops it after couple of seconds.
Never got VPN working successfully even in 2.2 and 2.2.1. It was able to connect to the VPN service (can't remember if I used PPTP or L2TP) but I was unable to browse any website or connect to anything on the internet.
I was told on some forum there's some bug in Android causing this. Anyways, doesn't sound identical to the issue you had but I thought I'd mention this.
Worked for me when using 2.2.1 JPY, both PPTP and L2TP. I suspect it's a VpnService problem rather then a pptp problem, so if anyone on 2.3.3 JVO or similar have VPN running ok, would appreciate if would send me on PM or attached here the VpnService.apk and .odex he run.
isn't it the same problem as posted on the android google code site:
http://code.google.com/p/android/issues/detail?id=4706
appears to still not be working in jvp.. no one seems to have it working with 3g on any phone with gingerbread.. it appears to work ok over wifi.. i also need i working in 3g in gb. .so i am staying on froyo for now.

ICS test firmware tackling Wi-Fi and HDMI issues

Please check the following firmware and report in this thread if it solves your Wi-Fi or HDMI issues.
http://update.archos.com/9/gen9/gen9_4.0.4-TEST/firmware_archos_it4.aos
There might be still some audio out problems with HDMI with OMAP4430 ES2.2 based platforms (check in settings->about tablet->OMAP version): we are still working on it and will come up with a solution shortly.
Thank you for your help/feedback and patience.
very tempting to try... but i will wait for someone to make a custom rom with root out of it...
This ROM is not intended to get custom ROM, with root and other options.
As far as i understood it is just a test ROM for users who have troubles with the official ICS update to check if this solves their issues.
Thus, if you are impacted, then just download it and test if it corrects WiFi and HDMI issues.
Cheers,

I am an Archos staff, I do not do custom firmwares: I do the real ones
Downloaded and installed:
-when updated from GUI (.aos copied to Gen9 when Android was running) resulted in no backlight after reboot; installation from recovery was successful
-as before Reset Android is required for the update, otherwise boot process hangs during dalvik-cache rebuilding
-Wifi works better but still sometimes disconnects- connected to 802.11n SoftAP (ar2971 usb wlan+ built-in Win7 wifi AP)
-there are no problems connecting to 802.11g- wifi tethering on HTC Desire (CM7.2, Android 2.3.7)
Sorry, I can't test HDMI- I don't have proper monitor/TV
I misplaced my charger cable..so I'm not able to test this. If I find it i will test this out and report my findings.

Problem : yes
in audio/video archos application i see the files in twice !those files are on SC card
I'm having some 'strange' issues on wifi, so have downloaded this update and will apply it and let y'all know shortly if it breaks / fixes anything
- EDIT- So far so good. The firmware installed without a hitch (I copied it to root of Internalstorage and selected Yes when tablet asked to upgrade). It rebooted, upgraded firmware, rebooted, optimized applications and nothing seems broken. However, it DOES (so far) seem to have fixed the issue I had with Wifi - the issue I had was when I click on a UTL, it loads the browser (I use Dolphin HD) and this says 'Cannot load the page as there is no internet conenction' but then it loads the page anyway. This (so far ) is not happening anymore. Will play with the tablet this weekend and update this post if I have more.
For the record - my tablet is OMAP4460ES1.1 (whatever that means) - Archos 80 G9 16GB Turbo
Installed the test-firmware, same wifi-problems as before. There is no stable connection possible (my router: fritzbox 3270).

I've forgot to mention- my Wifi AP is using wpa2 with AES encryption
Other thoughts- confirmation dialogs in recovery would be usefull (I've wiped storage by mistake today....)

I agree with u 100% that confirmation dialogs should be included. I've accidentally formatted before, thinking it would confirm. +1
Wunderful !
I can finally look back videos with sound.
Great Thanks!
WPA TKIP
I have changed the encryption-settings to WPA TKIP (former: WPA+ WPA2) on the fritzbox 3270.
Now everthing works fine!
my results seem inconclusive. previously, Wifi seemed to not reconnect for me after i turned my screen of (without manually turning wifi off then on again). I installed the test firmware, and it seemed to work good, however i booted back into sde firmware, and the problem seems to be gone there now? Doesn't make sense to me
if it helps:

Same result as official 4.0.4 update on my 101 G9 16Go Turbo tab (OMAP 4430 ES2.3)
* WiFi is still not working with my access point (D-Link DAP 1160 WPA2-AUTO), but i works quite well with my HTC phone when sharing 3G connexion (as i've got optical fiber connection, i'm not happy with just 3G internet),
* No sound on my Samsung video projector when connecting it through HDMI cable,

Logcat from my Archos tab attached.
Updated earlier today, fixed my Wi-Fi issues. Connections now solid and fast. Never had a problem with HDMI, can confirm it still works though.
Thank you Archos!!!!
Thanks! It works much better on wifi than before, but still not perfect.
I'm using it with an 802.11g network and WEP encryption (I know!)
Still occasionally loses connection, but nowhere near as often.
Haven't been able to test HDMI yet.

Loses connection less frequently but still a bit unstable
Thanks for the updated firmware, it is great to see Archos taking such an active role
My router is an Airport Express 802.11g w/ WPA
With the update, the tablet drops connection less frequently and always seems to pick it up quickly but still a bit unstable.
The tablet works perfectly for 8 hours spans without internet but as soon as you connect to a secure Wifi it rarely goes 30 minutes without requiring a hard reset. This happens less frequently when syncing is turned off but still makes the tablet pretty worthless for web browsing and the like.
Update - my G9 is still having wifi issues but less frequently. My browser sometimes reports `no internet ` before it loads page anyway and sometimes when I unlock my g9, it briefly shows `no internet connection` on the notification bar. Seems to me like it is dropping wifi completely when not in active use. However I cannot find anywhere to set/change this in settings

Any ideas of a configuration that preferable will not require root would be appreciated, any and all idea are appreciated.
Thanks!

Your issue is that it cant be used at the same time as they use the same hardware. As an example. When mms comes in and you are connected to wifi the radio disables the wifi connection for a sec to download it on the cell network. They both use the same antenna so only one connection is active at a time.
