Can't wait to see it, since i'm fighting with my Motorola on Linux right now.

BTW, is it possible to have internet access on Motorola phones using linux subsitute of mrouter?

Yes, it works exactly as in Windows.

That's great, i hope you'll release new guide soon.

Could you also write how to configure IrDA and Bluetooth connection with it?

Any news about that guide? Could you at least post some sources on how to connect motorola to PC with linux while you're still working on the guide?

Ah, sorry about that. It's been a busy month.

Quick'n'dirty guide:

Set up a DNS with 169.254.1.1 pointing to a920, and 169.254.1.68 pointing to wsockhost.mrouter.

Then, make sure you have PPP support in your kernel, and the pppd (PPP daemon) installed. You also need, of course, bluetooth support, hci_usb, rfcomm, l2cap and the device driver for your BT dongle. BlueZ (the bluetooth stack) has to be installed too.

Then, it's simply a matter of configuring hcid.conf and starting hcid and sdpd. After that you pair your phone with your computer.

Next, you add a serial port with

sdptool add SP

and start the Dial-up Networking Daemon (dund) with the following options:
dund --listen --channel 1 --msdun noauth 169.254.1.68:169.254.1.1 460800 ms-dns 169.254.1.68 lock --persist

That's basically it. This won't enable TCP forarding, though. You'll need iptables for that.

The complete guide should be done in a couple of days. Just hold on a bit longer.

I did everything like you wrote. I setup a DNS server (bind) with 169.254.1.68 pointing to wsockhost.mrouter


[ 23:36:27 :: root  :: ~ ] hostx -v wsockhost.mrouter
Query about wsockhost.mrouter for record types A
Trying wsockhost.mrouter ...
Query done, 1 answer, authoritative status: no error
wsockhost.mrouter       86400   IN      A       169.254.1.68
Authority information:
mrouter                 86400   IN      NS      ns.mrouter
Additional information:
ns.mrouter              86400   IN      A       169.254.1.69

and added 169.254.1.1 as a920 in /etc/hosts.

Everything seems to work. I can connect my Motorola via desktop suite to PC, but it disconnects after 90 seconds. It looks like it can't resolve wsockhost.mrouter addess but i don't get why. Right now i'm trying to connect via USB cable with ppp options like this:


[ 23:36:38 :: root  :: ~ ] cat /etc/ppp/options
/dev/ttyACM0
460800

lock
noauth

proxyarp
ms-dns 169.254.1.68
169.254.1.68:169.254.1.1

After i run ppp /dev/ttyACM0 nodeatch i get:

Modem hangup

I tried to ping a920 (169.254.1.1) but i can't do that. I can only ping 169.254.1.68. It looks like mobile still doesn't see my PC, but why?

I'm out of ideas. Same thing happends when i'm trying to connect via bluetooth. It shows connected to PC on phone and breaks it after 90 seconds.

I temporarily disabled my firewall (it blocks a lot of things by default) but still same problem.

Edit:

That's my ppp modules i have loaded:


[ 23:41:55 :: root  :: ~ ] lsmod | grep ppp

It looks like it can't resolve wsockhost.mrouter addess but i don't get why.

Are you sure it's listening on 169.254.1.68? Try starting BIND after you've established the PPP connection.

In the guide (which is still not finished, sorry) I will recommend using dnsmasq. It resolves hosts from /etc/hosts, always listens on all interfaces (unless you tell it not to) and is extremely easy to set up.

KrzychuG 19 Nov 2005, 21:42

Yes, i'm preety sure that my bind listens on 169.254.1.68 too. Just look at this:

I also tried with dnsmask. Same problem.

It looks like no data is transfered through cable/bluetooth to phone.

EDIT:

Could it be because of the flash i'm using in my Motorola? I've got 35.80.59 Generix, which is a modified version of 30.95.00. I've got some weird bleutooth problems with it too. It disconnects me sometimes without any reason in random moments.
