VPN on Samsung i5801

[Guest Grote.haas]

Hello,

I recently acquired a Samsung i5801 with Android 2.1(update 1). It would really be useful if I could use this phone with a VPN connection, since that is the only way to connect with the network of the university hospital.

The ICT-manager referred me to this adress: http://android.modaco.com/content/htc-desi...re-short-howto/

Since I have no HTC, i do not think the page is useful for me. Instead I have rooted the phone following the steps on this page: http://forum.xda-developers.com/showpost.p...p;postcount=112

Apparently I needed busybox, so I installed this by downloading it from the Androidmarket. The VPN-connector I downloaded from the first page I mentioned.

My problem is the TUN.ko file. I downloaded it here: http://forum.xda-developers.com/showthread.php?t=793018 and then I am stuck. I have no idea how to use the code that is mentioned.

As you can guess, this is the first time I use a smartphone but I really need the VPN connection.

Can someone please help me or point me in the right direction?

Tank you,

You enter that code into adb (which is part of the android sdk). Now you can get this by downloading the full sdk, with a guide here.

I think there was a minimal version of the adb tool but I cant find the link anymore. If I find it I'll edit this post.

Thank you for the help.

Unfortunately I have a new problem. When entering the code "mount -o remount,rw /dev/block/stl6 /system" i get this message: mount: operation not permitted. Do you have any idea why this problem occurs? I have followed the steps on the page.

You could first use "adb shell" then "mount" on its own to get a list of partition mounts as you may need to modify the "/dev/block/stl6" part to match the layout of "system" on the phone.

If that doesnt work, you could try:

adb remount

adb push tun.ko /system/xbin/

those do the same as the first set of code on that guide you referred to.

If you still get an error, I guess the root hasnt completed, so you may need to try rooting again, perhaps using a different method e.g. using an app called z4root (search on google).

Hello,

I rerooted the phone using Z4root, but this still does not work. I still get the "permission denied" message when trying to mount or remount. When I try the "push tun.ko /system/xbin/", I get a message "failed to copy ... read-only file system.

I'm guessing the rooting or busybox isnt working, but I dont have much experience with that phone. I might have access to that model of phone in a few weeks to try experimenting, but can't promise anything.

Hopefully someone else in this forum will know more. You could also try posting in the xda-developers forums, it seems they have more active users on this phone.

Ok, but thank you for the help anyway. :D

Hello!

Just to let you know, after a long search and a lot of trial and error, I finally managed to connect the VPN.

Here is what I did:

1. Turns out the SU wouldn't load because I was unaware I had to look at my phone to give permission... Silly, but it held me back for quite some time. :D

2. After gaining superuser acces, I had to mount /system read-write

3. having done that, I had to load the Tun.ko file:

insmod /sdcard/tun.ko

Since I had som difficulties putting tun.ko in the right folder, I decided to just load it in the SD-card root. Now I just have to remember not to delete this file when cleaning up my folders :D

So thank you for the help, the Z4root app was a great help. Even though it was a bumpy ride, I actually liked working with this code. I might even try to learn some more about it.
