[AT&T Samsung Galaxy S II Skyrocket SGH-I727] plarser48:
Just out of curiosity, how did you confirm that the TUN/TAP driver was non-existant or not operating properly on the skyrocket?

I'm in the midst of doing the same ... installing openvpn. I have the server set up on my home PC and verified through another laptop off-network. But I have problems when trying to run openvpn settings. Here is what I did:

1) Copied .ovpn file, ca.crt, client1.crt, client1.key, ta.key FROM server TO /sdcard/openvpn directory on skyrocket

2) Installed busybox

3) Installed openvpn installer

4) Installed openvpn using #3

5) Installed and opened openvpn settings

6) Under "OpenVPN Settings" I checked the box saying "OpenVPN"

7) Under "OpenVPN Configurations", I selected my .ovpn file's checkbox

8) The .ovpn checkbox immediately disables and I have no openvpn :(

Was your approach similar?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] jvanbrecht:
I just checked via lsmod. I did not bother going through the process of moving my config files from my captivate to the skyrocket.

Samsung does not include the tun/tap driver in the stock kernel, so it will require a custom kernel, or at least someone to create the module with the same libraries as the stock kernel and just the tun.ko module file to copy across to our current phones.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] gtj0:
Actually TUN/TAP is compiled directly into the stock kernel and not compiled as a module so you won't find it with lsmod. You also don't need to do an insmod to use it. I'm running openvpn just fine in tap mode.

There IS a bug in the OpenVPN Installer though that requires you to have ifconfig and route in /system/xbin/bb. It won't work if you select anything else during the openvpn install.

Here's what I did...

Install busybox to /system/xbin

Install openvpn to /system/xbin and select /system/xbin/bb as the location of ifconfig/route

adb shell or use a terminal on the device and do a su.

mount -o rw,remount /dev/block/mmcblk0p24 /system

mkdir /system/xbin/bb

cd /system/xbin/bb

ln -s ../busybox ifconfig

ln -s ../busybox route

mount -o ro,remount /dev/block/mmcblk0p24 /system

Configure and start openvpn.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] jvanbrecht:
Good to know.

Will try it in abit, I tried to run openvpn, but it failed on the tun driver, which is why I stopped, but I did not link bb, will give that a try when I get a chance... stupid ATT busted me for unauthorized tethering again.. so cannot get my existing openvpn config from my server yet...
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] plarser48:
gtj0:

I tried the directions you provided but with using tun and no luck. I'll try and reconfigure my openvpn server to run tap and will try agian.

jvanbrecht:

let me know if you make any progress
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] gtj0:
I just reconfigured my server over to tun mode and it's still working fine.

Can you try running openvpn from a command line and see what errors it spits out?

I.E. openvpn --config server.ovpn

Also can you check if /dev/tun exists?

edit.....

Here's my config...

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] jvanbrecht:
I had no problems getting it to work, I borrowed my co workers usb modem to pull down my configs from my old Captivate (I use ssl-admin and store the configs with the certificates in zip format).

The problem I am having at the moment is getting tethering to work while openvpn is running.

Laptop can talk to the phone (using wifi tethering, usb tethering kills the adb session, but I suspect it would work just fine), and phone can talk to the world, but laptop will not connect to the world.

The routes are in place, I checked the sysctl options, and ip forwarding is enabled. Just no traffic will pass... it is driving me nuts... heh.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] plarser48:
Success for me too! Not sure what was wrong. The server was always working no problem and was always able to connect directly over home wifi from laptop. But I wasn't able to connect on the Skyrocket.

But I used gtj0's config file, changed the remote ip address/port, and worked perfectly. Thanks!

jvanbrecht: I haven't tried it with tethering yet and probably won't get to until at least a few days. Hope to be able to help by trying on my phone sometime soon.

Everyone: Any idea if it is better to run tun or tap for mobile phone openvpn? Regarding tethering, do both tap and tun hide detectable elements like TTL at the IP layer?

EDIT: VPN Not Porting Properly?

Hmm. It seems I am able to connect no problem and openvpn on the phone says it's connected. But when I go to www.whatismyip.com from my phone, it still says an AT&T address. I expected with openvpn running that it should show my home server ip address no? Also, openvpn on skyrocket indicates that it is connected as 10.3.0.6. But if I try to ping 10.3.0.6 from the server I get no response. Is that expected?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] gtj0:
TAP provides a bridged connection so broadcasts on the server's network are propagated across the connection. For network-to-network connections this may be needed for things like dhcp and windows networking. For end users, this usually isn't a good thing because it eats up bandwidth. TUN, which is routed instead of bridged, is the better way to go.

My config only routes traffic destined for the server's LAN over the vpn connection so the behavior you see with whatsmyip is normal. Check openvpn's config file paramters to make the vpn the default route for all traffic.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] jvanbrecht:
See my other post. I included my configs.

Just add redirect-gateway option to your client configuration, or the server side client configuration in the ccd directory.

I have everything working. As for what att will see. Only an encrypted tunnel initiated from you phone to your vpn server. Ttl, ip options etc will not be visible to att.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] plarser48:
Cool thanks again. I'll try updating my configs and trying again tonight. I'm sure not being able to ping across the tunnel was probably a configure issue a well.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] jvanbrecht:
You also need the Client to Client option enabled if you want the openvpn server to advertise routes to other vpn client devices and their associated networks. That would be another reason why you cannot ping across the tunnel if you are trying to ping another vpn device.

[Samsung Epic 4G Touch] hijewpositive:
Hey guys, this has been an ongoing problem since the last epic i had, which is the crappy bluetooth audio quality. I know for a fact that its a touchwiz thing because i didn't have this issue with my Nexus S. Only the Epic, and the Epic touch. Since so many people have really dodged trying to fix the solution (Other than certain ROMs) I just wanted to know where I can find the Bluetooth Stack to maybe try to fix it myself. I'm running a rooted stock kernel. Please just point me in the right direction and I'll take all the chances after that myself. Thanks a lot guys.

I know there is threads about this already. I'm on the 69.99 400min and unlimited everything else including unlimited roaming. Has anyone ever used this Verizon prl for a whole month on the same plan I have? And did Sprint charge you extra or cancel your account? I just don't want to get screwed over that's all. I just find it hard for sprint to charge you when it is already free roaming, or is there fine print somewhere you'll get f'd?

Help me out and I will hit your thanks button

[HTC EVO 3D] KB112:
It really is hit or miss. I used it and did 100mb roaming 2 months, then 500mb one month. My ass got hit with the warning letter. I see others posting they do 12gb and they hear nothing. The terms are no more than 300mb roaming or a majority of data or minutes used.

Also, be aware that every minute you use, counts as part of your minute totals. Roaming minutes are not included in your free mobile to mobile service. So since this prl is forced roaming, every minute you use is deducted from your plans 400 minutes.
[HTC EVO 3D] mrjaydee82:
Well now I'm scared to use it now :-(
[HTC EVO 3D] KB112:
You will get a warning letter before they cut you off. Just use it sparingly, which I did. Just that one month I used it for streaming some Pandora at work. Bastards nailed me on it though...weird. But I think its because my plan raises eyebrows anyways, not supposed to have 6 lines on a single ED 1500 Family plan like I do. Plus some extra discounts/credits. So I am just playing safe and trying to stay under the radar now. :)
[HTC EVO 3D] dastin1015:
Normally the people you hear about using large amount of data roaming using that PRL is probably because of the old data plan which actually included unlimited roaming. I think it is more recent plans have the 300mb cap.

Nah, we all have Unlimited Roaming listed...but there is fine print. There are no old plans these devices can be on except for Corporate type plans, Sero, Employee etc. This is from my acct right now, just started my new month a few days back.

actualy u still get nights and weekends just no mobile to mobile
[HTC EVO 3D] sitlet:
The fine print with unlimited roaming states that roaming minutes should not go above half of the total of your on-network minutes. So if you used 200 roaming minutes, you should use at least 400 on-network minutes to compensate.

And as for data roaming, it's not a hard cap, but anything above 350mb a month will make sprint start watching you. I personally use above 1gb a month roaming using that prl and haven't gotten a letter.

[Eee Pad Transformer General] goodintentions:
No offense, but after reading your post carefully I decided any reply I have is futile. You got the transformer with the wrong attitude. You've been using it with the wrong attitude. And you've been expecting things with ALL the wrong attitude.

It's best that you stick with a win 7 netbook or notebook.

PS - I have not touched my laptop since April. Between my PC at home and my transformer on-the-go, I have no complaint whatsoever. I see your complaints comparable to the complaints of someone who got a motorcycle intending to use it like a car.
[Eee Pad Transformer General] laikinasis:
Thank you for an oppinion. Yes - my expectations were "something resembling a netbook with a hint of phone". But it's neither a phone, nor a netbook and the tasks I wanted it to do were very limited by the software, which I didn't take into account when considered buying a tablet...
[Eee Pad Transformer General] phoranix:
i agree more or less. i owned a 701 too btw. i now own among others an eeepc 1015pem. but i use my transformer all the time. google editing is a bit awkward yes, especially with large docs, but google has his own application for that. it eases the pain a bit.

copy and paste, yes editing is not that easy. i own docs to go, but the user interface is not that intuitive. polaris seems to saves not always that good (it cant be opened with all others wordprocessors). open document format is not very easy to use.

but still i prefer transformer at work for all sort of reasons:

* battery, i can use the transformer (with dock) all day long, with no other hussle.

* it is cool

* boy is the transformer silent - i like that way more than i anticipated.

* the touchscreen, although not always that easy, i love it.

* being more in the cloud (dropbox with 50gb), gmail, and polaris/docs to go, calendar, google contacts, it all works together: fast and easy. i like that too.

* i like the looks, and the way the transformer feels.

* at work with dock, at home: mostly tablet: reading, viewing, surfing

btw i am used to use linux on my netbooks, win 7 moves like a snail.
[Eee Pad Transformer General] Spidey01:
I have to agree with GoodInte tions over there; which is ironic because the EeePC 1015PE Netbook that I havent touched since September, was bought in April :-).

For your needs Android is not effective, for me it is almost as effective as BSD or GNU/Linux; where you use gdocs I use programs that I can run in a Debian chroot or I use a PC, rather than try and use LibreOffice locally with X/VNC.
[Eee Pad Transformer General] Rumbleweed:
For someone who took the time to write that thorough analysis, I would have thought you researched the TF with the same level of thoroughness. Everything you point out in your dissertation has been discussed in detail on this forum.
[Eee Pad Transformer General] asdfuogh:
Yes.. exactly what Rumbleweed said. You said you bought this 3 months ago; then you got it around September, which was about 2 months after I got my transformer (if you got it right at the start). When I first got my tablet, I didn't look through any of the online stuff, but I did start about a week after getting it (to know how else I could improve it further, but I was pretty lucky as my B5 had no problems except for a slight creakiness on one side).

Anyway, by around 4.5 months ago, I already knew several points:

-browsing rendering had some issues, some of which was solved by hardware acceleration, etc. (although, I didn't really notice this as an issue until I looked online because my laptop is old and slower by far)

-document editing is a little flawed because typing lags behind the physical typing

-movies.. well, I saw lots of threads about not being able to play 720p except in Dice Player or something, but I don't really watch HD stuff often except maybe for tennis (btw, espn 360 worked perfectly and looked great for streaming)

-there are a lot of trivial games (I was disappointed with this one too, but I found the emulators soon after, so I haven't played much other trivial games except for the more addictive looking tower defense ones)

tl;dr: I don't understand how you didn't know this by the time you got it as you seem pretty thorough (as per your post). Good luck though, I wanted a Windows 7 tablet before in the past, but they're either expensive as hell or ugly looking as hell.. We just need Google and other tablet-making-companies to realize that tablets are for more than entertainment.
[Eee Pad Transformer General] Spidey01:
OT but I always thought it was just me and my B50 with that, on the right/starboard side. Just happy to have none of the serious problems I read about here lol.
[Eee Pad Transformer General] jordanjay29:
Honestly, why not root and stick Ubuntu on there? I realize this would destroy the Android flavor, but that's obviously not what you're looking for.

Specifically:

1. How is not having 3G any different from your EEE PC with wifi? If you wanted the TF with 3G, there's a 3G version. Otherwise, I'm sure your mobile carrier will happily sell you a hotspot device and plan.

2. Do you have the dock? Ctrl+C, Ctrl+V, Ctrl+X all work for me on the dock. As for an office suite, how about using GDocs? I know it's not as slick as MS Office or LibreOffice, but it's pretty functional.

3. Yeah, I've found that anime can be something of a pain at 720p and decoders aren't brilliant on Android. It's what happens when the majority of the population uses iTunes, Netflix and Hulu for their media, manufacturers get lazy. I really wish VLC would come to Android, with proper codec support (especially with ICS' per-app hardware acceleration capabilities).

4. You know there are non-Gallery photo viewer apps, right? That's the beauty of Android, EVERYTHING (especially if you have root :P) can be replaced.

5. Have you looked at the TegraZone? Or some websites for game reviews? It's honestly like trying to find a game for PC, there's a lot of crap to wade through, even in non-casual games.
[Eee Pad Transformer General] Gary13579:
Have you tried using Polaris Office with GDocs syncing? I know Polaris has some Google Docs support. Does the Android app for Google Docs work at all for you? As for the internet comment, how was your Eee PC any different? The TF and PC are the same in that regard. This isn't a Chromebook or anything...

I've had no issues with media playback since Dice Player came out. It handles all of my 720p or smaller video no problem. Even scenes that were always an absolute ***** on my tablet, like high bitrate Big Bang Theory intro (that always raped it) run great in Dice.

I'd say better than okay, I love how it syncs pictures between all of my devices with Picasa.

So keep looking. There are plenty of pretty featured RPGs. Go look at Gameloft games. Most of them are kinda crappy, but definitely more than angry birds.

Uhh.. just because Tegra 3 is coming out doesn't make tegra 2 any worse... the TF 1 is still amazing hardware.

You don't currently have a smartphone? I'm far more productive with both. It's easy to pull out the phone for 5 minutes and check my email, read news, etc, but as soon as I need to reply to a client, the phone is absolutely useless and I pull out the TF. I tether my TF to my phone for 3G/4G anywhere. If I need to open a large PDF, spreadsheet, ppt, etc it's a pain to do it on the phone, but so much better on a tablet. Ebooks are also great on the TF, as is videos.

Other pros: super thin, battery life is simply *amazing* (I can be on it for 14 hours a day and it doesn't need a charge), quiet, no heat, great audio output for music/video with voodoo sound, touchscreen that lets me take complex math notes that would be hard to type quickly, allows me to draw out theories and ideas anywhere I am (I used this all the time for solving puzzles in video games, working out the answers to the google nexus twitter challenges), plus it turns into a freaking TABLET when you disconnect it (call it a gimmick all you want, it's still badass).

By the silimilar time I did not know about:

1. Google market search (how it's hard to find a decent app or a tablet optimized app)

2. Copy paste issues (ctrl+c / ctrl+v is STILL not supported in many apps)

3. Video playback. It's rather annoying to use ~5 video players. 720p by itself is not an issue. Almost all players support native (hadware) decoding. I had more problems trying to open lower resolution movies in, I presume, less common containers / codecs.

4. Page rendering in browsing. I mean that different browsers may render the same page differently. This was an issue in pc world loooong time ago and it's now almost non-existent.

It's an interesting thought that I do relate.
[Eee Pad Transformer General] laikinasis:
Didn't know about Polaris GDocs support, thanks. It works rather how I expect it to work... Speaking about Google Docs - the most common task I do is writing grades to studens in a spreadsheet. In normal PC's, you click a cell, write something, click on another. In Google docs (and most browsers I tried on Android, except one, that is REALLY slow) you click a cell, edit it and must press "SUMBIT". It's a big setback, when you consider larger amounts of editing.

I use that player too. Lots of unopened files, like with other players. Again, it's not about the smoothness of the playback, it's about supporting different codecs / containers.

Could you suggest an app, which would work like default Gallery app, but support inner folders ?

Believe me, I am looking ;)

I thought about owning both of them. Maybe it's the solution I'm looking for, but now it seems that phone may replace most of the tablet functions.

Thanks for your answer.
