MTU settings fix (in progress 90%) snappier internet, xbox live connectivity. - Captivate Android Development

Thanks to Angrym0use for putting this out there. I know this can be done for some reason i can't get this to set. I was hoping someone could give it a try and see if this works for you. I had it work for about 5 mins and now i can not get it to stick back. (i might of done something in terminal that I can't remember ..**** happens)
STILL CAN'T GET MTU SETTINGS TO STICK AS OF 10/18/10
Orginally I wanted to maximize the MTU(maxium transmision unit)to help with internet efficiency and speed to 1500mtu because it is locked down at a sad 1400mtu. As a added bonus as i searched for a solution to this with my limited linux networking comands. I stumbled around and found out that this fix will also enable our captivates to tether xbox live. This works because our stock setting is too low for xbox to work. Proof it works video here (http://www.youtube.com/watch?v=h02C9Zz6hG0)
Download terminal emulator.
Make sure you have root access.
While in the terminal type:
su
(that will give you root permission)
cd sys/class/net
(change directory)
cd pdp0 that is our data connection
(type LS if you want to see your all your adapters)
mtu=1500
(setting mtu)
To see if this worked type: ip link list
If that dosn't work try and type: ip link set dev pdp0 mtu 1500
I tested my mtu at http://www.speedguide.net/analyzer....460&SCALE=8&TTL=120&TSOPT=0&SACK_PERM=1&IP_TO

I guess you will have to check the source code, maybe the setting is hard-coded on the driver source or some settings file.

When i restart they do clear the settings,however i'm still unable to even test it at 1500. However i did for a brief second the first time i set this up i terminal Hmmm. I saw it for a sec on my laptop. I'm a linux super noob so I was kinda hoping someone with a little more skill would find this interesting. I've done all I can. I thought perhaps it was mobileAp giving it problems so i tried to disable it while setting mtu (no dice). I'm sure someone will nail it down. This would be a great bump for this phone!

I would live it if this would work..

i get told it cant cd pdp0. and yes i have root access. im running cognition 2.1jh7ota if i try the other way i get either dev is duplicate or 1500 is garbage

# cat mtu
1280
WOW, stock is only 1280!!
----edit
got it set and surviving reboots
MTU = 1500
MTU is fully optimized for broadband.

Wanna tell us what you did?

I did this with terminal emulator.
I did vi mtu
changed value to 1500
saved and it worked.
Requires vi knowledge and knowing how to use control keys in terminal emulator.
Could probably be done with root explorer as well - probably easier that way...

doesn't stick on reboot tho..
I just made a simple bash script that runs on boot.
Lowers the ping pretty nicely

Rebooted mine and checked my interfaces and it listed properly at 1500 - How did you mod yours?
Before your startup script?

Nice, I just finished watching Date Night with my wife (funny as hell). I'm glad you guys found that...yeah right 1280 that is so pathetic! I bet it lowered ping!!! Sweet. Let me know what you do to get it to sticky sticky!

applying the fix to Cog after some more tests

LOL nice~! Xbox 360 live via tether Android...
I"ve been digging for a solution for month now! LOL sad... but at least it got done!

Oh don't get too excited, make sure you test the packets for packet loss. The rwin values should adjust to the new mtu but you never know. If you have any packet loss slide down the mtu values!

If you want to see the MTUs for all the interfaces on your rooted phone run ifconfig with the a switch.
I am on a rooted JPH. MTU is 1500 (all stock)
busybox ifconfig -a shows stats on all interfaces.
pdp0 will not show up if you are connected to wifi because your 3g data is temporary disabled while using wifi.
Too bad the settings do not stick. DG will fix it for yah.
edited.---------I guess I missed the OPs "ip link list" command.

I was thinking we might try to apply this other adapters as well.

what kind of data usage would xbox live use?? I don't have internet during the summer and end up tethering a lot....and i would love to have some live!! I'm still on unlimited data but i dont even have a clue as to what kind of data it would use

For example MW2 would be couple 200-300 kilobits, problem will not be download and upload speeds but pings. I've heard good reports so far.

hm, speed test went from 1380 to 800 down when i switched mtu to 1500

are you having packet loss? Do you know how to test for it?

[Android] Run Android without a data plan [CHECKLIST]

Hey Gang,
I currently do not have a data plan and won't get one until I switch from Sprint to Verizon. (accounts expire soon)
This is what I want to do with my Vogue:
Setup SD card with EXT2 partitions [CHECK]
Correctly install/run a SenseUI/Hero build [CHECK]
Convert my WM contacts to Android contacts offline [CHECK]
Install APK's offline [CHECK]
Use the internet connection through my PC via USB cable (while running android) [PENDING]
Install a "camera software" APK so i can use the camera [PENDING]
Enjoy the hell out of Android and all the possibilities for the Vogue! [CHECK]
Any and all help checking off my list is much appreciated!
~Syn
The camera already works out of the box. and Talk to enatefox about internet via USB connection.
Install a "camera software" APK so i can use the camera [PENDING]
I am currently using "Pro Paint Camera that came with this Hero/SenseUI build.
I can take pictures but not video. Also, none of the lighting effects work so every picture is very yellowish.
True.... the camera does work, but it is not really usable without adjustment.
I'm in the same situation right now. I want to use android but I'm afraid I wont be able to use internet to access the market (unlike WM/ActiveSync).
The camera issue is something that I can deal with, but I think that it would be nice if someone could make an activesync-like program that can share internet.
Only difference is that I'm on verizon right now, and might consider switching to sprint!

I forget exactly when that build came out, but I can assure you that the build I'm using now has a camcorder and camera app outside of Paint Pro Camera.
FWIW, I'm using the Droid donut ion build by Zenulator.
Also, from what I know, internet through USB only allows you to browse the web, and the marketplace doesn't work. There might be some changes in the future, however.
Yes. with Cupcake / Donut the camera/camcorder seem to work with the default applications. They still don't have filters or effects to correct lighting.
... still looking for that app.

I have also been trying to figure this out... but getting Internet via bluetooth rather than USB. So kind of like the bluetooth tethering that is possible right now with Android, but in REVERSE! So Internet-> PC-> Bluetooth-> Android.
USB Internet (at this point) can be very problematic. It can cause your phone to hard freeze out of the blue. I haven't spent a lot of time troubleshooting it since it's hard to figure out what went wrong when I'm forced to reset.
Credit to DimaFern for getting me anywhere near having this working. I just messed with it a little. This is reverse tethering because you are not getting the connection from the phone. So the USB Tethering option is not related in this situation.
Here's my howto
I have not tried this without a Linux host. I believe you can forward traffic with ICS but I don't know what is involved there.
My gateway is .37, my laptop is .107 and the phone gets it's IP from the laptop:
On laptop:
echo "1" | sudo tee /proc/sys/net/ipv4/ip_forward
On Android:
ip addr add 192.168.37.100/24 dev usb0
ifconfig usb0 up
## This is the IP for my laptop:
route add default gw 192.168.37.107
setprop net.dns1 192.168.37.107
cat /proc/net/route
Click to expand...
Click to collapse
The last line is not needed-- it's to show you that it's routing traffic. You won't be able to ping IPs from the command line and somehow Market doesn't think you're online but SAM Market, Browser, etc. do work. It's nice because you are not taxing the RAM of the phone for connectivity so it runs much quicker... unless it hard freezes on you.
i use tetherbot to tether my phone now that it's running android full time. basically install tetherbot and start the socks proxy server on port 1080 then.
Code:
adb forward tcp:1080 tcp:1080
from your computer and set up firefox to connect manually to the proxy.

I'm sorry, but isn't Tetherbot used to share your phone's internet connection with your computer?
I think we are trying to be able to "reverse tether" and not tether.
enatefox (and others)...
I would love to see how this reverse-tethering can work. I know its very complicated and buggy right now, but if you do any more work on it you should create a thread showing how in layman's terms. I have dual-boots on both my computers into Ubuntu 9.10, I know what the terminal is and sudo and some basic commands, but when you type your commands with little explanation I get lost. They could use some clarification [ such as 1) open terminal 2) type these commands. ] And please explain terminal in Android. What apk do I need? I probably have it already but just need to install it. Thanks for any help. I don't have data since my line costs $10 a month (family plan) and data would be $26 a month. I just started reverse-tethering with WM6.5.1 and its really cool.
There aren't any other steps you just run what I posted and change "192.168.37.107" to what your desktop's IP is and "192.168.37.100" to "192.168.xxx.100" where "xxx" is the subnet of your LAN-- matching the 3rd set of numbers of your desktop's IP.
You can run these commands over ADB, which is required to do this. Here's a guide on how to set it up.
Here is what I came up with trying to do the same thing with bluetooth instead :
http://forum.xda-developers.com/showpost.php?p=4404512&postcount=9
I was missing your "ip addr..." command to add the forwarding network, this should help, I will give it a try.
I also came to the conclusion that I needed a way to fake that either the wifi or the data connection was up. Maybe this can be done by issuing a "setprop" command forcing the status to being "up"?

UGH I'm stuck right now. I'm using Ubuntu 9.10, and when I type in terminal "sudo /etc/init.d/udev restart" I get some error message telling me to do it a different way. So even after restarting the computer, it does not recognize any command for adb. I already did the export PATH to the androidsdk/tools folder and adb is in there, but I cannot get it to open. Any ideas?
Got it to see adb. I forgot to put /home/drkow19 in front of the path...
edit: Has anyone successfully used ADB with zen's 2.0.1? I'm trying right now but it shows no devices connected. In the 50-android.rules file I have 0bb4 instead of 18d1 like enatefox said to. Also, on the Dream forums the file they use is 51-android.rules, whats the diff?
0bb4 and 18d1 are determined in the source code. Different versions can change so whichever is shown, use. The 50 and 51 are indicators for timing. Maybe I have this backwards but 51 should start later than 50 and can address issues with it not being recognized or more precisely, overrode with another operation. I set mine to 51.
Okay I deleted 50 and used 51-android.rules. What is the line about "define vendor id" does that need to be in the 51 file?
I can say adb start-server but no devices... They say you need to sudo adb start-server but when I try that I get "sudo: adb: command not found" How do you add the adb PATH so it works under sudo as well?

[Q] usb reverse tether to feature phone

I have a basic samsung feature phone. Id like to use this as a modem for my Acer if possible. This phone works fine on all my ubuntu systems - just plug it in for the first time, click next-next in the wizard and I'm online. On the tablet, I see that it shows up as a /dev/ttyACM0. I belive this means that its a matter of getting the correct chat commands and associating pppd with the android layer. I imagine the process must be similar as to getting a USB 3G dongle working. Does anyone have any thoughts on how to do this?
There are already some threads about tethering the tablet to your phone, as well as 3G dongles.
http://forum.xda-developers.com/showthread.php?t=1152869
But yeah, no solution yet.
got it working
I thought I'd post the info on how I got this working for my specific situation. I have not read many other threads about this so maybe this type of info is already out there.
My phone is a basic samsung feature phone on AT&T that I called up and got unlimited data for $10/mo extra. This phone is practically unusable for browsing on itself. I plugged it into my ubuntu laptop and basically the tethering worked right away. I thought then that it should be able to work on the tablet. I wanted to make sure that "unlimited data" also applied to tethering to a computer. They said yes, if you can get tethering working - still no limit. I get 1-2Mbit rate over it.
This is on a rooted tablet, of course.
When I plug it into my tablet I get a single /dev/ttyACM0. If your phone is similar, you maybe able to use this info.
I went to At+t website and found this:
Then I read the man pages for pppd "man pppd". From this information, I understood how to modify the sample scripts "gprs", "gprs-connect-chat" and "gprs-disconnect-chat".
I then came up with a suitable "ip-up" script, based on ones found in the Huawei 3G modem example code. This is called when a ppp0 connection is made. Some of the lines in there I am not sure of, but it works, regardless.
I was surprised to find the standard "chat" program was not present in any of the roms I'd tried. Currently I am using virtuous Xoom. Somewhere, I found "chat-ril" which did the trick.
I've attached "modem.zip" which contains all the mentioned files.
From a root shell, you type:
pppd call gprs &
(This is kind of a pain but I'd like to find a way to automatically do that when the phone is plugged in)
If you do ifconfig ppp0, you should have an address, then try to browse.
Now I'm watching Netflix on my A500 as I drive! Also google navigation is absolutely great on a tablet, once you have the data connection.

Thanks for the work, but what are we to do with the modem.zip file you provided?
Modem zip contains the scripts and the chat-ril utility that need to be copied to your tablet. There's two ways to copy the files to your tablet:
1)
first unzip the files on your PC
use adb and push the files over to your tablet in the corresponding locations under /system.
2)
unzip the files to a micro SD or USB stick
remount the /system partition as read/write
copy them to the corresponding locations in the tablet filesystem from the SD or USB stick.
Copying files to your /system partition is described elsewhere in the forum but I can give more detail if needed.
I'm admittedly a noob on many levels. I think I followed your instructions but I get:
# pppd call gprs &
# /system/bin/chat-ril: permission denied
Any suggestions?
make sure you do it as root by typing 'su' first. Also check the permissions of chat-ril binary to be executable.
Thanks, it was the chat-ril with incorrect permissions.
So going with what you provided and much help from Google, I was able to make my own set of scripts for my phone and carrier (a Nokia 5230 and T-mobile). It looks like it's connecting both in my shell on the tablet (all "got it"s and OKs) and on the phone side which shows it with the 3G connection in use. Executing that ifconfig ppp0 gives me an ip address with a [up point-to-point running multicast].
My problem is I can't seem to access anything on the tablet. I can ping google from within the shell but the default browser, Dolphin, and the rest of my internet accessing apps don't work. I did change a line in the ip-up file from /system/bin/setprop "net.interfaces.defaultroute" "gprs" to "3g", which is what I named my connection script. Is there something else I'm missing?
Thank you for all the help.
Well, the good news is you can ping which probably means it can work and you are just about there.
The stuff in ip-up I don't completely understand myself, but that's probably where the issue is. By that point I was so close and anxious, that I just manually did some 'setprop's and experiment until it worked. I had exactly the same issue where I could ping but not browse at one point. Also, make sure the dns setprop's are set. Are you sure the "3g" should not be "gprs". I'm not sure that has to do with the script name. But maybe just the fact that you can ping means that's ok. I'm just not sure. Good luck.

[How to] VNC server in a pinch + Webtop w/o HDMI [Moved to Beta]

Moved to Beta
Stepping Closer to Perfection
Ello,
Been messing with this for a bit now and think I have a decent set of instructions organized for getting a vnc server (with resumable sessions) of your webtop in a pinch for those times you say "where the hell is a hdmi/dock/etc when I need one" its a little repetitive but simple as hell hopefully someone who knows more can set up the x server config to include this set up as a just in case.
Pre-recs
Of course Root!!
Full Native Ubuntu Webtop (Sogarths webtop2sd here)
Terminal Emulator (I recommend this one)
And vnc viewer something like really shouldn't matter.
And you'll need to fix your dependencies using this regardless of which mod so you wont have to worry about not being able to use apt to install things.
Any form of a custom dock not stock version e.g. xfce-panel, debain panel or genome otherwise you'll have no dock at all (I am working on getting a way around this for DebainMOD/stock dock users)
More Pre-recs DO THIS BEFORE ANYTHING!! WHY? because I rather that than I told you so XP
BACK YOUR SH%^T UP I recommend using the more expanded CWM Due to its backing up sd-ext and osh
Fun stuff:
Open Terminal Emulator
and enter the following minus (anything in)
su
(get root for term)
/usr/bin/sudo - u adas bash
(get into the webtop enviornment, can be used alot XD)
sudo bash
(gotta love root)
({or just} /usr/bin/sudo -u root bash {for easy way to root shell})
apt-get install tightvncserver
apt-get install lxde
or just
apt-get install tightvncserver lxde
(install a vnc server and a desk environment)
tightvncserver
(run before the config worked best for me it'll ask you to set up a password then ask if you would like to set up a view only password which I liked with this I used getvncstate for that one jic I wanted to see if it was running up to you really)
(now config the vnc display, this way was the least fubar'ed x display I managed to get working and repeated)
export USER=adas
vncserver -geometry 1024X800
(if you ran this before the previous set thats fine after you might see a localhost:2(ect) don't worry if you did this before first use you'll be asked to enter a password. once set enter the next line by line)
cat > /root/.vnc/xstartup
#!/bin/sh
xrdb $HOME/.Xresources
xsetroot -solid grey
icewm &
lxsession
(then hit ctrl-d twice then enter should get you out, that is pretty much where you select what you want to have started in your root environment in vnc if you don't want stock dock or the webtop panel remove them lxsession starts xfce if you used that you can also add gnome -session or panel which ever)
(now to fix known keyboard mapping issue for 9.04 from root terminal in webtop run)
apt-get install nano
nano /root/.vnc/xstartup
(add the line {export XKL_XMODMAP_DISABLE=1} before /etc/X11/Xsession or gnome-session or if you have another way of adding this that'll do)
(use gedit to do this on one of my atrix's webtops was sooo much easier XO)
(now hit the home key and open up your vnc viewer on your phone)
The drop down should be newconnection
Nickname: adas (or whatever I use root)
Password: (the password you set up if you dont remember then...try below steps for reconnect)
Address:localhost
port: 5901 (5902 worked too x.x idkw)
(the press the connect button XD Always exit your vnc connection before leaving it!!!!)
(This should not fubar your x display for hdmi/dock/etc but did notice that on the first run re plugging the hdmi loaded the moto screen with a black screen though rebooted it went fine though the vnc server needed to be reset so...
Get to webtop root through the terminal emulator and run...)
tightvncserver
(you'll be promoted to set up another password, once done you can go back and use the vnc view settings you had before and get back in do what you need and exit and you will beable to plug in too hdmi/doc/etc without loading up a completely grey screen with the nice useless x courser XP)
Now the really fun part kicking myself that I didnt realize this shortly after setting this up, but you got this vnc server running on your webtop but you really arn't big on messing with the tiny screen while your on a wifi and you have access to a computer or even your pluged into a computer and have moto phone portal open on it.... well haha just download a vnc viewer get your IP address (from network or the phone portal ip) on the network and plug
(the x's are your IP numbers being that every network might be different you get the diffrent)
XXX.XXX.XXX.XXX:5901
as the target address and you be asked to enter a password that you set up and note that the 01 in the port suffix is indeed the display number.
And bamn easy access to your webtop on your Atrix while your chilling and using your TV for what every you watch XP
Any suggestions changes or better how to's post your stuff and Ill add it with quotes this will not work in any of the Debian mods Images/Including Blacktrack 5 (v.v) due to not being able to load the linux app from the command line Tho will work on the DebainMOD/ w apt sources fixed. I'm looking into getting into chroot after I finish up my tweaks from a fresh test run.
Known Half Way Marks: Use Seamonkey Browser to replace firefox while using vnc sessions. The sessions are in root user which is fine for the pinch use, but if you wanna resume what you were using on the webtop from vnc veiwer in hdmi and vica versa I need some one to look at the commands and see where it is I marked up above where I think it is the grey part x.x will update this part think I'm closing in on a solution to this, and it would reflect what you see on the hdmi and be shared XD
Known pita: Screen time out..... kills the tightvncserver display as well >,>
For now the most recommended use guide can be found here you don't necessarily have to plug into the HDMI of the initial launch if you follow the steps above, although not the intended direction mostly the safest if you follow these steps being that currently without X or Xvnc being configured you may very well mess with your HDMI at display at DISPLAY=:1 being that the vnc method at this point exports the root environment only the method below is safe and would do XP
See this for the direction of vnc without use of a dual boot within chroot still needs messing with as mentioned above back your Sh%^t up X3

I've finally made it work the way I wanted but it probably not the best or easiest way to do it...
1-)First I plugged in my HDMI cable over my phone and my tv and got Webtop V1 running.
2-)From lxterm I issued the command 'sudo bash backtop' (this is very well explainned over this thread)
3-)Once I got the terminal from BT running then I issued the 'ui' command that is a vncserver built-in into backtrack5 ARM distro and with the default password of 123456789 (you can change it by issuing 'vncpasswd' command if you want..)
4-) Now you can unplug the HDMI cable if you want.
5-) And you are ready to connect at the gnome version of Backtrack from your cell phone using any of the vnc clients available on the Market with no need of the HDMI anymore...
Concerns:
1-)How about battery life after that? will it be drained since bt is running "in the background" ?
I didn't tested yet... and have no idea atm... will let it running here to see if it get warmer than normal or the battery last shorter (of course it will not last longer...)
2-) Is there a way to run this commands without the HDMI cable plugged-in?
If anyone interested (or even you Djazin) want to see some directions/hints there is a thread written by an X10 owner that have some scripts to be used at the phone terminal, the X10 doesnt have the webtop (duh)... not sure how useful it is for us but maybe the scripts he wrote can be used....
As we were discussing before in this thread if I try to run the command " sudo bash backtop" it gives a lot of errors from mount points unreacheable to DISPLAY problems... I will post the errors here just in case any one reading have some good ideas to contribute:

This looks really interesting. I'm not able to test right now, but I wonder how come this one didn't get more views/replies until now.
Anyway, thanks OP for sharing, I'll test it ASAP.
Thanks for the guide!
Just wondering something... what if we have a way to run the webtop without a dock/lapdock then put some kind of vnc server and through the phone itself (with a vnc client for android) to access it as a remote computer..... Am I tripping?

The Webtop runs alongside the phone as it is you can get to its shell through a terminal emulator (I installed all of this through terminal emulator on the android side) and run tightvncserver after setting this up and access webtop through a vnc client on the phone screen.... now if you mean to access the webtop's vnc server from a local remote computer work/home over the network then... heh that would take alot of config within tightvncserver probably with a parallel program like xauthority configured to run the vnc server with a lan address 192.168.x.x and so forth how to do that Im not sure I thought about it earlier this morning but atm Im trying to get backtop working x.x
as for tightvncserver options run
toghtvncserver -h
Though atm there is no vnc server working on the atrix android side

Oh I will try that... but I am not sure how to run webtob without plug anything on it (such HDMI over tv or lapdock) ... may I just issue the startx command over a terminal? do the xterm works if I issue it through a connectbot or something? Do you suggest something else?
I actually want it because of the Backtop (my backtop is working fine but I need to run it with sudo bash backtop command thats why I want to vncview it ...) may I help you somehow?
can you clarify what does this actually do...does this mean i can vnc from my actual phone to the webtop on my phone screen?
or can i use this to access webtop from my vnc client say on a laptop on the same wifi network...

Second needs tweaking but in theory I don't see why it wouldn't I'm working on getting backtop without any form of the Debian mod then Ill get back to that.

its easy from terminal emulator run the following without (anything in)
su
(get root)
(then run)
/usr/bin/sudo -u adas bash
(or just)
/usr/bin/sudo -u root bash
(Thats all)
and your in webtop with no hdmi/gui from here you can infact install vncserver using the steps above or just run commands without accessing the gui now xterm needs a gui exported display of "any" kind because it is mostly like a vm there was a way once you got up up and running you can access from command line only but I'ma have to dig for that within the Debain Mod posts I used to get it done when I was using them, but I cant for the life of me recall.
If you can post how you were able to get Backtop to work in that thread for it it might help I got the same output that one user posted in page 3 of that thread.

How? I can see through 'ps' command that xinit is running .... but how to issue a vncserver command or something?
My backtop runs through that webtopmod from Joe version one and the bt img on the /sdcard/bt folder including the scripts backtop and stopbacktop .... Are you planning something different from that?
Sorry all the dumb questions I did... just read the OP and saw everything I need.. now I am researching about to change the 10.77.32.150 address from sources.list that I actually have on my /osh/etc/apt folder... to be able to install the tightvncserver...

Nice hint man I finally did the apt-get to work and installed the tightvncserver! Now I just need to make it works openning a valid xwindow ( actually it is openning the xwindow with nothing but the crosshair)
But so far thank you for all your help!!!

is the x window grey or is it showing a the webtop background with no dock, if its the first you need to run the cat > /root/.vnc/xstartup command and add the text below it from the op or you will cause the vncserver to export the x server settings bare which at this point is a pita to set up for the adas user environment though root exports fine atm I updated the code group under the cat command try them from root in which ever webtop terminal you prefer to use, I'm actually doing this from a stock webtop again to check it out that and I wanted my Debian mods back so I can try to set up vncserver for them as well.
Last night I was messing with the webtop's x server and found a more native vnc server built into the very x server that supports hdmi we possibly might be able to get vnc server to export the hdmi display as soon as I figure out where to put the shar display commands for vnc access but for now this seems to work fine in the root environment and its safer than what I was trying last night hehe I switched the hdmi cable display with the root environment that was accessed through vnc but no key pad so it was interesting to see, thought it didn't survive my tinkering.

Recreated that problem you were having go to /root/.vnc and delete your current xstartup file then from terminal run
tightvncserver -kill :1
tightvncserver
and you should be set

run the kill command then in root explorer kill xstartup in /root/.vncserver then run tightvncserver and it should load the mouse and a grey screen and then it'll load the root desktop just after that (give it a few seconds). if not reboot and try it all again.

#!/bin/sh
xrdb $HOME/.Xresources
xsetroot -solid grey
icewm &

I am still getting the grey screen with nothing but a crosshair mouse pointer.... instead of lxsession can I use something else?

Post your config your version of webtopmods's active what your osh-wrt-1 and 2 sh files are set with and What dock are you using as well as the settings your using in the vnc viewer, I'ma try to recreate your set up on another Atrix I have and see if I can crack what your problem with the root environment is.
Note if your just using the AWN dock try something else, though even with no dock it should at least load the stock wallpaper with the mouse cruiser. And you did delete the xstartup file found in /root/.vnc and not try to recreate one?

Well my webtopmod is Joe Ferreira v1 and I've installed the webtop2sd from Sorgarth... about the wrt-osh 1 and 2 I'm gonna need to know how to get them to you... I 've some linux knowledge so just tell me where they are... My vnc I am connecting at the port the server is telling me (i.e: localhost:1 - 5901).
I'm not using Any dock at all... nothing connected through the hdmi port....
I'd deleted the xstartup and when I run the tightvncserver it was recreated with different values from what u suggested ... it recreate the following content:
#!/bin/sh
xrdb $HOME/.Xresources
xsetroot -solid grey
#x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
#x-window-manager &
/etc/X11/Xsession
By my knowledge in linux and vnc I am suspecting that it's not being able to load the icewm xwindow...

Reverse Bluetooth-PAN Tethering how to enable? Like XOOM and Transformer, Please!

How can i enable Bluetooth-PAN Tethering for internet access?
Like Xoom and Transformer?
I dont see the connect to internet under the profile.
Am I the only one interested in Bluetooth reverse tethering?
It is way better then using WiFi, Battery last a lot longer on both your phone and tablet, I dont get why Acer does not just enable this! what do they have to lose on it.
Please anyone that knows how to Make roms, can you make a patch to enable this on all roms? it looks like all we really need i just the profile.

Nope, there are alot of people interested, that's why there are around four current threads going about it. No joy yet.
So I did some digging and it looks like google uses http://www.bluez.org/ for their Bluetooth tethering, I am not a program, but all source code and apps are in there, can someone please make a package if possible?
Thanks
Reverse tethering needs work to integrate it better with android..
From the linux side if you run as root (at the command line or in a shell script):
Code:
pand --connect XX:XX:XX:XX:XX:XX
sleep 3
dhcpcd bnep0
setprop net.dns1 8.8.8.8
will connect you to the paired device with ID: XX:XX:XX:XX:XX:XX
(You can probably find the ID for the paired device by name by running as root:
`cat /data/misc/bluetoothd/??:*/names`)
In a post of mine on google plus referring to tethering the Icona A500 through the new pan feature in the HTC Dream ezGingerbread rom I mention a problem I'm having with this however:
This will properly set up networking; and allow basic networking tasks such as browsing the web work.. however any sync tasks will still believe the device is offline thus sync updates and market downloads will not happen.
* FYI the sleep command is really only for automation; dhcpcd will fail if pand is still connecting;
i tried it i get permission denied when i try to execute pand commands
and yes i am su #
i think it has to do with the new ROM 3.2 from 501, because even in adb when i do shell i get access denied.

check /system/bin if the binary exists (I'm still on 3.1).. if not you may need a copy from somewhere
i gave up on the original rom and replace my rom with PRIMEE_AcerIconia-p9-5a.zip
i lose the rear camera, but i dont use it anyway
I have the same problem.
In the other ROMs, I can pair a bluetooth device like my iPhone 4, configure this device pressing settings button and in a section called profiles must be appear "internet".
How can I solve it?
Sorry for my bad english.
I Install nook bluetooth tether.
it works well, you need to pair first and then add widget and activate.
the app was writen for gingerbread so widget acts up, you can activate, but if you try to deactivate you need to go to setting\application and stop the app.
here is the app

About BT PAN
In custom rom PRIMEE based on Asus Transformer 8.6.5.6 with my mobile SE W660i Bluetooth PAN works fine.
Yes it does but rear camera stops working

Any way to bypass T-Mobile tether?

Like they tittle Say anyway to bypass T-Mobile tether?
If rooted...
Then theres various ways to bypass and if used together chances are good you won't have to pay 2x for data: modifying your apn to allow dun type, adding the line: net.tethering.noprovisioning=true
to your build.prop and finally using adb from a PC (u can try this even if not rooted) type the following from cmd or powershell: "adb shell" followed by "settings put global tether_dun_required 0" without the " "s and restart your phone n hopefully that should do the trick.
If still throttled by TMo go into Magisk and install tethering_enabler or TTL tethering modules. These modules weren't specifically made for the 6T but they should still be effective. If still unsuccessful then modifying the TTL from the device your trying to tether to will help hide the source of data aim for TTL of 65 to confuse tmo.
If your not rooted then use PDANet USB tether to a PC and hide tether options then create a hotspot from the PC your USB tethered to or use the WiFi Sharing option in PDANet PC Menu. At least thats what works the best for me and I've tried many many things... One other possibility if your on stock no root is to add a new apn with all the same info as normal fast.tmobile.net lte apn only enable MVNO type to GIO for apn type leave it blank and save it. This should hide the default TMobile apn (and make the editor think your using a 3rd party like Mint) now go back and edit the new apn and under apn type put: dun,default,mms,supl try and save it. It should error n say dun not supported... Press Home and force close settings-reboot phone. The dun sometimes will stick if this method isn't patched yet I'm sure it will be soon.
Your final options are to use an app from playstore like VPN Hotspot or VPN Tether they might slow your speed a bit but they should tunnel all your data thru a VPN confusing TMo as to the origin of data. Probably the best and easiest way is by using a custom ROM as most haven't been tainted by Google's latest CarrierConfigManager commits or carrier apn restrictions. If anyone knows how to reverse these commits easily or any other methods not listed please let me know.
I'm currently looking for a clean TMo only dun enabled apns-config.xml so I can overwrite the default n modify the build.prop for a quick fix on any new ROM or update...
As you can probably tell being throttled or having to pay 2x for the same data is a pet peeve of mine and I've spent some time researching the topic. I'd love to hear what ended up working for you or if anyone knows a solid method I missed. Or has a recommendation for a good ROM with unlimited hotspot features built in for the 6t let me know.
I installed the app from this thread, https://www.xda-developers.com/vpn-hotspot-share-vpn-connection/. You can also download the app in the Playstore. I also subscribe to Private Internet Access (https://privateinternetaccess.com) and they have an app that you can download from the playstore.
My phone contract has overseas roaming for a number of days but it restricts tethering and hotspot when roaming. The way I bypass this limitation is to run the PIA VPN, then run the VPN Hotspot app, and use the "Repeater" function. This has worked flawlessly sharing my internet connection with other devices..

Be sure you reset APN to default values after you install this new file....
Thanks bro I'll test it out...if it works care if I add it to the main post? Yeah I mentioned the VPN app along with a VPN my only issue with that method is the decrease in speed and some apps/devices don't like the VPN way much. Wish google would stop letting carriers dictate Android or itd b nice if the US would put their foot down and not allow companies to bend us over lock our bootloader's, phone's, devices we pay for or try and swindle us by charging 2x for data or throttle us...

Not sure what I did wrong, but it's not loading for me. All my APNs disappeared. I reset to default after replacing with the one provided.
Well, I know this post is rather old, but I made a Magisk module that does everything for you...
