Re: connect to internet via android phone as usb-modem
I've reverted the udev usage and test now for 'easytether' when checking
for the driver and assign driver to 'easytether' if so. I've diff'ed vs
latest git, but tested vs 0.8.4 rc1 and it works fine for me.

Re: connect to internet via android phone as usb-modem
Hello,
I've changed the hack to now check for a udev environment variable
'NM_PSEUDODRIVER'. If set, the lack of a driver is ignored.
The /etc/udev/rules.d/easytether.rules declares this if an easytether0
device is detected.
If need be I can revert it to check for 'easytether' in the code, but I
think the udev rule based approach is better.
Bye,
Torsten

easytether works on Fedora 14 with my U8230 , I will try yours patch
(maybe if I had time )

Two suggestions for the patch:
1) Kill the first hunk, lets just set a driver name anyway
2) In the second hunk, instead or printing a warning, lets do something
like this:
if (!driver) {
if (g_str_has_prefix (ifname, "easytether"))
driver = "easytether";
else {
nm_log_warn (LOGD_HW, "%s: couldn't determine device driver;
ignoring...", path);
goto out;
}
}
That makes the hack more contained and gets rid of some of the
extraneous logging. If you rework the patch and it works fine for you,
I'll merge it. Thanks!

You can buy various apps that add the functionality, usually in combination with having to enable "Developer"/debug mode on the phone. I don't think that requires a full jailbreak of the device though. One such app is "easytether". Early versions of Android did not include things like the required kernel modules for hotspot mode (ie AP mode firmware, driver capability, or even the kernel iptables NAT modules) and thus you have to resort to doing tunnels with apps like easytether or openvpn.

Well, I had to invoke a wrapper script:

Minor typo in "ignorning device driver not found" :) Here's what shows in syslog: /sys/devices/virtual/net/easytether0: couldn't determine device driver; ignoring... easytether0: is an easytether device, ignorning device driver not found Ignoring driver = NULL for easytether Perhaps have the code that spawns the first warning not do that if it's an easytether device.. Anyway, the NetworkManager side of this works fine - thanks! For whatever reason, /usr/local/bin/easytether is not getting started, so I still have to run that manually. I've edited the sample udev rule with correct attributes for my device, so I don't know what's going on. No big deal - I'll mess with that later... As an aside, it would be nice if the mobile-stream folks (authors of easytether) would address the missing sysfs bits, and perhaps make the easytether client daemonize properly -- currently it grabs the console regardless of whether it's backgrounded or not. I mailed them quite some time ago asking for an ARM client, and they indicated that the plan was to eventually open-source the linux client. Perhaps some encouragement from here will help :-) -RW ___ networkmanager-list mailing list networkmanager-list@gnome.org http://mail.gnome.org/mailman/listinfo/networkmanager-list

Thanks for the advice where to patch network manager. Attached is a very
first version, plus a basic udev rule for a Motorola Milestone and
connect script. It works fine on my Ubuntu 10.04 machine right now,
though it could use some polishing.

Mobile hotspot is clearly the better solution here, but for older versions of android, if for some reason you can't run an XDA/Cyanogen build, and you're using easytether, there may be some hope. The problem with easytether is that it's a closed-source blob on Linux and thus there's no way to improve the interaction between it and NetworkManager in the future. We're stuck with whatever easytether decides it wants to do today, and we have no recourse to improve it. That said, the best way to go about this is likely to use udev scripts to initially create the easytether0 interface, and then we could add some custom code to NM to recognize the easytether0 interface as a normal ethernet device and run DHCP on it. That wouldn't be *too* hard, probably < 30 lines of code. It would involve using g_str_has_prefix() looking for easytether in the nm-udev-manager.c code, and if so, bypassing some of the udev /sysfs hierarchy checks that determine hardware relationships and device attributes like driver and description. That's not something we should be doing for most "virtual" network interfaces, but it's probably OK in the case of easytether.
