How To: internet over usb/bluetooth

[mightymop]

ok to make a prog like gnubox we have to do:

1. find out how the kvm is knowing that there is a gprs connection...
2. find a way to fake the "gprs is online" settings
3. code a prog that routes the traffic

any suggestions on this?

I guess that CSD being dialup uses some form of PPP sort of protocol, from gnubox it looks like it is PPP. Now gnubox modifies the registry of the phone to prevent it from dialing and directly connect to the IP. Now I was able to run a hello world on my phone which ensures that my cross compiler is setup. However, I ran into the memory full problem and can not even change the ring tone or alarm time. So first I need to get familiar to this phone.

[mightymop]

hehe ok let me know if you could need some help... maybe i could code some classes you need or something other
we are going to solve it!!!

hm.. i think i will also install a crosscompiler today..

to know where we have to edit the system settings, that kvm knows it's online, we should make a hole copy of the system files before a connections is opened and while we have one.. then we are able to make a diff and could maybe find out in which file we have to add/edit our fakeconnection, right?

I saw some files int NetProfile folder under /ezxlocal/... infact there is one file for every GPRS / MMS / WAP profile that I have, but I was unable to get the file over to my PC for inspection. But I now have some clue where to start.

But my ultimate goal will remain the same, to get information about the phone's APIs so that we can move to OPIE as a replacement.

Motorola tried to be smart. They left out the juicy stuff from the kernel and implemented things in user space no matter how simple ioctl(s) they are, they are probably out of the GPL scope so if you file a petition you can get the kernel and probably some EZX's modified qtopia info, but that won't be enough to move to OPIE

[mightymop]

yeah a completly new phone environment would be cool, but opie is not stable
anough and still does not support all the phone functions we would need...

what about a project to make a program like gnubox?

Ah good to see someone who wants to switch to OPIE too. Damn i wish i could code a bit better.

learn it

everybody wants to have a new environment, 'cause the original is bad

but we should begin with little steps and first try to get the existing environment working as we would like to have it...
i mean: SURFING IN THE NET OVER BLUETOOTH OR USB!!!

anybody with some infos about gprs and how kvm knows its linked to inet via gprs/csd out there?

Faking a GPRS connection for KVM and Opera turned out to be trickier than I thought. Its not enough to have a GPRS connection running. These programs actually insist on routing through it, even if default route is set to ppp0 rather than gprsv0. Even renaming ppp0 to gprsv0 (by a kernel module) didn't do the trick.

To make a long story short, I managed to get Opera and KVM talk to the internet via ppp0 (bluetooth) but in a messy way, and only if a GPRS connection exists (although no packets will be sent over it). I did it by using the netfilter layer to reroute packets to ppp0 right before they get transmitted, and faking incoming packets from ppp0 to appear as though they're coming from gprsv0. Works like a charm but a headache to configure. If people here want it anyway, I may write some scripts to do it, if there's enough demand. (PM me if you see a real need in this functionality).

Note that mightymop's original question still stands. The way I did it is an ugly hack. If someone can find the way to tell internal applications not to insist on routing via gprsv0, it would be far better than my current solution.

In the meantime, I got the other direction working. I added NAT support on the phone, and got my laptop connected to the internet via GPRS (over PPP over Bluetooth ). If anyone is interested in such functionality, PM me and I'll upload the scripts to do that. I think its is actually more useful than the above (NATting the phone behind the laptop). I any case, I managed to do both, as a proof of concept.

Hey Mack,

Please upload the scription as we like to definitly try out.. Persnally, I badly need it!!

Thanks Dude,

Gr8 mack! I would also love to have internet through bluetooth ppp0, but I don't have a GPRS. Is it possible without the need for GPRS? Am currently working on pppd running over windows, got modem connected (modem log on WinX says so) but no ip assigned to phone yet. Will post the same when am done, if anybody interested. If anyone already got it working, please let me know.
