Re: N900 as a Wifi Hotspot, part 2
 

I still have a problem using Titan's kernel. The mobilehotspot backend seems to start properly, I see the hotspot on my computer but can't manage to connect.

Here is what dmesg give me:EDIT: removed the lines related to PC Suite Mode connection

Re: N900 as a Wifi Hotspot, part 2
 

Nevermind, I uninstalled nmap and mobilehotspot is working properly now.

Re: N900 as a Wifi Hotspot, part 2
 

nmap? how can it interfere?

Re: N900 as a Wifi Hotspot, part 2
 

hmm i just installed the 0.3.0 version, rebooted. and was able to start it without problems. but i couldn't find it with my macbook.
so i stopped it and tried to start it via the terminal.

now all i get is the same error eitama got on page 3. even after another reboot of the N900.

Re: N900 as a Wifi Hotspot, part 2
 

I think eitama and I had the same problem. Try installing my tweaked backend and see if that helps.

Re: N900 as a Wifi Hotspot, part 2
 

Flynx, I actually gave up on mobilehotspot untill pr1.2 comes,
and managed to get Bluetooth DUN working.
But I saw your post, and decided to give it one more try! and it worked!!!!!!!!!!!!!!!!!

I put you backend,py file, rebooted after install and it worked!
Thanks mate, I don't know what you changed there but I suggest this be incorporated into the original package.

Re: N900 as a Wifi Hotspot, part 2
 

It's a simple sleep to make sure the gprs0 interface is fully up before we try to start dnsmasq. In theory the backend already waits for IcD to return that the connection is up before continuing but it might be that IcD returns a bit prematurely or something.

In any case I'll be making a slightly smarter wait-for-interface system soonish.

Re: N900 as a Wifi Hotspot, part 2
 

I don't know (yet), but I uninstalled nmap (the one from devel), and I could connect to my N900 even without reboot. The only strange thing remaining is the connection is not encrypted even when I set WEP in the frontend (I didn't have time to investigate).

Re: N900 as a Wifi Hotspot, part 2
 

I'm glad I was able to contribute in some small way. rambo will have a much more elegant solution soon, when he has time. I think I read somewhere he has a phd thesis to finish up or something.

Re: N900 as a Wifi Hotspot, part 2
 

Slightly off-topic but I was using my N900 in Coventry this weekend to connect my laptop to the internet. Beware the dreaded Fair Usage Policy! Strictly speaking, that is not allowed on my network but it works fine via PC Suite.

Anywho, very limited usage for browsing over the weekend resulted in nasty text from network re: fair usage.

Point is, the tech works fine. The networks don't like it, even with "unlimited" data bolt-on.

Re: N900 as a Wifi Hotspot, part 2
 

You confuse me with someone else, just busy with work etc (I'm a conslutant).

Edit: though it's somewhat amusing that someone would think I'd be gunning for Phd, I wonder how long until there's a forum submeme to the tune of http://www.schneierfacts.com/ (though there's a lot of people smarter than me in this community that would probably be more deserving)

Also I noticed that the issue was not with the gprs0 interface and that more elegant solution might be overly complex.

Re: N900 as a Wifi Hotspot, part 2
 

I've been trying to use this with my Wii, but I can't figure out what IP it should use, nor gateway. What settings should I use? I used these instructions: http://mobilehotspot.garage.maemo.org/

Re: N900 as a Wifi Hotspot, part 2
 

Have you tried with a laptop to make sure it works in general ? I have no idea how Wii handles ad-hoc networks but if the hotspot is running correctly it will serve DHCP so manual setup should not be neccessary.

If you run "sudo /usr/sbin/mobilehotspot_backend start" via terminal there's a bunch of output, among that the network (it's 10.xx.yy.0/24 where xx and yy come from the wifi MAC address. N900 address [use as gw and dns server] is .1, use .110+ for manually configured devices)

Re: N900 as a Wifi Hotspot, part 2
 

Yes I have tried with an Win XP netbook, it works without any problems. The wii sees that it's a unprotedted ad-hoc connection, and do it's connection test, but I just get an error code that it cant find the access poing and I should confirm the SSID.

Re: N900 as a Wifi Hotspot, part 2
 

I did notice in the fine print that my carrier specifically restrict sharing a data connection to multiple devices, but they have no technical way to enforce that restriction.

Fortunately with T-Mobile in the US, you pay for unlimited, you get unlimited. I have downloaded DVD ISOs, full-length movies, etc. Never an overage or a complaint.

Until I cross the border into Canada....

Re: N900 as a Wifi Hotspot, part 2
 

that is not 100% correct. they could use the OS fingerprinting technology to figure out how many different devices actually using the same connection. with that way it is not only possible to identify an OS (and count how many machines are behind a NAT), but in some cases it is also possible to identify single machines every time again! and if you use more then one device, they could disconnect you.

anyway that wasn't what i wanted to post.
looks like 0.3.1 solve my problem and it works now.
but now i run into another problem... or let's say i have an idea for an enhancement.
after stopping the hotspot, the phone should look for existing WLANs.
from what i could see here it stays connected, even if i'm in reach of a WiFi network that is known by my N900.

Re: N900 as a Wifi Hotspot, part 2

Do I need to go back to school to become one of those.....;)

Seriously, my wife thinks I'm crazier than usual for the uncontrolled laughter.

Re: N900 as a Wifi Hotspot, part 2
 

It should try to connect to the connection you had active before starting the hotspot and anyways it should turn automatic wifi scan (if it was one prior to starting the hotspot) back on (since it has to be turned off while hotspot is in use).

So to clarify: There is no need to explicitly connect the the GPRS before starting the hotspot: the hotspot backend will take care of switching the connection.

Re: N900 as a Wifi Hotspot, part 2
 

my n900 was overclocked with litho's kernel. after i set up mobile hotspot with the projects kernel OC is gone. what should i do.
reflash with litho's kernel ?? will it affect the hotspot application

Re: N900 as a Wifi Hotspot, part 2
 

I have no idea if that kernel provides full NAT (and even if it does but the package does not state it you have a problem), try titans kernel-maemo AFAIK it has OC too.

Re: N900 as a Wifi Hotspot, part 2
 

I have titans ulv kernel 20 or 21 (not sure) with mobile hotspot working perfect.
I used it this morning for 40 minutes without a glitch.
It was supplying internet access to my SIMless Nokia N95, so that I can have internet there to use waze gps software.

Re: N900 as a Wifi Hotspot, part 2
 

can anybody confir if the litho's kernels have NAT support i would like to use them for OC as dont want to experiment with the new one

Re: N900 as a Wifi Hotspot, part 2
 

Since flashing the kernel takes about a minute you can just flash the kernel (and reboot) and then see if the hotspot backend still works, if not then it's tough luck.

AFAIUnderstand the "first" OC kernels were using exactly same config as stock (except obviously for the clocks) and thus do not have NAT. But I have lost track of which kernel has which features... (for example my hotspot kernel has only NAT and QoS in addition to stock, titans kernel-maemo has a ton of generally usefull features)

Re: N900 as a Wifi Hotspot, part 2
 

i would have tested if i could
actually my gprs is not working and i cannot test hotspot that is why i asked.
thanks anyway

Re: N900 as a Wifi Hotspot, part 2
 

Naaa i don't switch to my UMTS connection manually. I see that the mobilhotspot app is switching to these connection (i'm getting the white dot with the two lines in it) and the WiFi icon disappears.
That happens if I click on "start", but after clicking on "stop" the WiFi connection doesn't come back again. at least not directly, but i have to say I never waited the full 5 minutes.
that's why i suggest that this "scan for an available WiFi" should be triggered some seconds after the stop-button was pressed.

Re: N900 as a Wifi Hotspot, part 2
 

i installed titan's kernel 21 it was working fine but when i tried to play a video it said format not supported. the video was playable before.

then i flashed my device and again installed the kerne but it was same.

please help what should i do. the device gets very hot . i used the oc settings 125mhz to 900mz. and stock settings 250-600. the results was same.

should i try kernel 22

You are in the wrong thread mate.
Better post your question in the overclocking thread.

Re: N900 as a Wifi Hotspot, part 2
 

Hi. I have Joikuspot but wanted to try Mobile Hotspot just for kicks. Well, I installed the software but it didn't work. Not a big deal. I uninstalled and now my Joikuspot doesn't work. No matter how many times I install / uninstall it doesn't work. What can I do. I can connect to my phone but no data transfers. I tether with no problem.

I don't want to point fingers but its either Mobile Hotspot or Autodisconnect. Those were installed about the same time. I've since removed them both but Joikuspot still doesn't work for me. Any suggestions? Thanks.

Re: N900 as a Wifi Hotspot, part 2
 

Hi

First of all awesome stuff this mobile hotspot!
After installing the mobile hotspot debs, I had some trouble with the cifs module though. Dmesg error on modprobing:

Is this hotspot kernel missing something that was present in the stock kernel?

Also wouldn't it be a good idea to remove the dependencies to the custom kernel and modules from the mobilehotspot_0.2.0_all.deb? This way the mobile hotspot can be installed/updated while using some other 'custom' kernels which also support everything needed for doing nat.

Re: N900 as a Wifi Hotspot, part 2
 

geohsia: I've heard somewhere that this joiku spot is using a custom kernel module. Maybe it's no longer working because of the change of kernel / module directory?

You could maybe check the link /lib/modules/current to see if it's reset to the original modules dir

Re: N900 as a Wifi Hotspot, part 2
 

No but if the cifs module is compiled for the stock kernel (I mean compiled later, ie not included in the default stock config) then there definitely is version mismatch.

Edit: The hotspot kernel is configured literally by adding a few options to the stock config as generated by the stock makefile, see hotspotize.sh.

The other kernel should use the same scheme as me and titan use with Provides: -line (for example http://maemo.org/packages/package_in....6.28-maemo24/).

Correct dependencies and provides declarations are the base of sane package management...

Re: N900 as a Wifi Hotspot, part 2
 

Any progress on getting Infrastructure mode working?

Re: N900 as a Wifi Hotspot, part 2
 

No, userspace NAT is the next priority I think (since wek has a solution for it it "just" needs to be integrated [which needs a major redesign of the whole backend...]).

But if it's important to you feel free to start experimenting. Best way to get features you feel important is to figure out how to implement them and then supply patches...

I spent over a week in the futile effort of trying to get working kernel-space NAT for stock kernel when starting this project, (learned at lot while at it though) wek and qole have spent a lot of time on the userspace NAT solution. No need to be expert outright, willingness to learn and to spent some time at it will go a very long way.

Re: N900 as a Wifi Hotspot, part 2
 

Thanks for the reply.

I do not exactly understand why there should be a version mismatch as both kernels were compiled from the same source? But I must admit that I do not know much about how this version checking works exactly.
I'm not sure that I understand what you mean here. What happens if another package which requires a custom kernel config needs to be installed. Let's say a package that needs usbnet supported. Then the maintainer of this package needs to recompile hotspot-kernel with the addition of usbnet? And would the package on which it depends still be called hotspot-kernel?

I don't think you should have a dependency to a certain kernel config. I've never seen it done anyway.

Re: N900 as a Wifi Hotspot, part 2
 

Because hotspot kernels version string is 2.6.38-hotspot and stock kernels version string is 2.6.38-omap1 (or something like that), titans kernel has again separate version string. This is done for a multitude of good reasons.

It's not a certain kernel config or even certain kernel package, it's certain kernel feature, and when the software will not work without said feature it must depend on it (or there is no sense packaging it at all).

This if why mobilehotspot depends on either hotspot-kernel or kernel-feature-netfilter, now titans kernel happens to provide said feature, hotspot-kernel also provides that feature but the dependency is listed like that to prefer the hotspot-kernel if no kernel providing the netfilter feature is yet installed (of course the hotspot kernel is not in autobuilder yet since I have been lazy and since titans kernel has much more features)

If there is a package that needs the usbnet module then it should specify that dependency in some commonly accepted way (like the kernel-feature-xxx that we coined with titan) and if maintainer of same package happens to maintain a package that provides this module to stock kernel then his package should state that it provides said feature (again the dependency can be stated as his_package | kernel-feature-xxx to prefer his).

He could also compile the usbnet module (since it's one of those that are easy to compile afterwards and the ko insers fine since it does not depend on anything changing in the kernel proper) for the hotspot kernel too and name that package hotspot-kernel-modules-usbnet (or something along that line) in case he feels that people using the hotspot kernel are better served by this than switching to titans (or some other kernel that provides both usbnet and netfilter features).

Getting a new feature enabled in titans kernel requires just informing him why this feature would be usefull (as long as it does not have weird conflicts with other features but generally usefull ones do not)

Re: N900 as a Wifi Hotspot, part 2
 

HI,
Thanks for the reply. I'm right now set at 2.6.28.10power-omap1

I've re-installed joiku many times but still it doesn't work.

What's the difference between the package that pops up on the extras-dev repository and the manual configs.

Re: N900 as a Wifi Hotspot, part 2
 

Please move this discussion to either the relevant kernels or joikuspots thread.

AFAIRecall titans kernel has the joikuspot module compiled in but maybe Joikuspot itself is being stupid (hint: trusting a symlink "current" that is provided by a package is not smart, the software could figure out the running kernels version [and by extension exact module path...] with a very simple call...).

Re: N900 as a Wifi Hotspot, part 2
 

Hi Rambo. The reason I brought this up here was because my system was working fine until I installed this Hotspot software. I didn't think that it would break Joikuspot.

I do have a messge in another Joikuspot specific thread, but I'm trying to track backwards to see what I would have to do to restore functionality. Just looking for some help.

Re: N900 as a Wifi Hotspot, part 2
 

Joikuspot was working fine with titans kernel but stopped working after installing mobilehotspot ? That would be interesting but I cannot see how the hotspot would mess joikuspot up in any permanent way. The frontend does nothing but set some configuration variables and run the backend script, the backend does insert some kernel modules on start and might not be able to remove all of them on stop (due to interesting interdependencies), said modules might interfere with Joiku (but in that case Joiku has serious issues to begin with) but reboot will always solve that.

Edit: If you want to get rid of titans kernel run "apt-get install --reinstall kernel kernel-flasher && reboot" as root (this will reinstall and flash stock kernel).
