Thursday, April 24. 2008Emobile on Ubuntu Linux
--- Warning! ---
The following departs from the usual topics of my blog and is probably only of interest if you use Ubuntu or you hate Ubuntu and would like a good reason to diss it. -------------------  Emobile D02HW Getting it going in Ubuntu was quite a mission - but I did it! As is usual with these types of things, Japanese language forums have quite a bit more info than is available in English. So here is my set-up and how I did it. (no guarantees for you!) Environment: Sharp PC-CS30H lap top running Ubuntu Linux 7.10 (Gutsy Gibbon) Getting it going! 1. Plug in the modem BEFORE you switch on your computer. I can't get it to recongnise the modem if I plug it in after I've started up Ubuntu. 2. Do not use gnome-ppp as recommended in other forums. I absolutely could not get this to work. 3. Open a terminal and type 'sudo pppconfig' 4. From the pppconfig utility that pops up, select 'create a connection'. Call it emobile-ppp and hit <enter> 5. Change the settings to those shown in the image below.  6. Save the emobile-ppp profile and quit pppconfig Now here is where it gets a bit weird - perhaps this is just my set-up, but it works for me. 7. Change (still in terminal) to the /etc/ppp/ directory 8. Type 'sudo pon emobile-ppp' This will not connect you to the internet, it should but it doesn't! 9. After a few seconds type sudo poff 10. Type 'sudo pon emobile-ppp' again. Within a few seconds you should be connected. For some reason running 'pon' and then 'poff' seems to reset the modem so you can connect when you run 'pon' for a second time. 11. To diconnect from emobile type 'sudo poff'. This took two weeks of trial and error! Speed is OK, but I'm getting nothing like 7.2Mbits/s. The best I've seen is about 2.5Mbit/s. It often drops down to about 600Kbit/s - presumably when it's roaming on the DoCoMo network. Although my experience could be seen as negative, the fact is, despite not being supported by E-Mobile, this is running on Ubuntu. If you hack around enough, you can do ANYTHING on this OS.

I'm extremely interested in your experiences with this device, and it seems like a pretty amazing coincidence of timing... I was on the verge of buying this device, and I think you've pushed me over the edge to trying it. I'd like to keep in touch and share experiences. (I hope you can see my email address on this comment, but the website includes a JavaScript-protected email link, too.) My main reservation was actually about shared experiences in English.
Not sure if it will help understand your problem but I also run Ubuntu on a Sharp, and I've found that it has a problem with network initialization there, too. My workaround has been to simply disable and reenable the networking after booting, and that seems to make it happy (after a few seconds). A few points of clarification. It sounds like no device driver is needed for Ubuntu. Is that also true under Windows? And have you tried using the device with any form of Internet connection sharing (such as Microsoft's own ICS)? Would eMobile get bent out of shape if I use it to connect my entire home network rather than connecting and disconnecting each computer individually. (Yes, I'm sad to note that I have several of them.) Anything else you want to share about performance, reliability, and so forth would be appreciated. I've actually been using their parent e-Access service for a couple of years, and have been mostly satisfied, though my current plan is to dump all of it except for this device and a keitai. From four or six companies down to two?
Hi I just read your JFTC submission for 2006 because I have just submitted mine in this year's.
I am sorry to hear you were crossed with the decision by the judges. I actually thought the judges' decision were right in choosing the winners. I may not be qualified to judge essays but I do have some opinions about your essay. First of all, I thought your essay's presentation was good and choice of words were appropriate to describe the context of the paragraphs. If I were the judge I would have liked to see more disruptive but original ideas that can raise eyebrows. I was quite suspicious reading the content and couldn't help thinking that the learned judges must have thought, "tell us something we haven't known". Also, I would have liked reading applications rather than functions e.g. Japan is high tech, Japan is polite, miniature is the way to go etc, without committing a method of the way forward. It came across as toadying someone without knowing if the person has what it takes to do the job. Then we have to be realistic in coming up with ideas based on the character of the country. Wind turbines is a clean renewable energy system but it may not necessarily work well in Japan if a major part of the country is either shielded by mountains or islands or like in the case of Tokyo, shielded by the Odaiba. Anyway, these are just my thoughts. Did you also participate in this year's essay? We can share our thoughts about the topic.
Hello,
I just purchased a new UMPC using the eMobile cheap service as well, making the laptop almost free. Though there was a disclaimer when I subscribed saying I needed my OS to be in Japanese for it to work, I thought it was bullsh*t. Well, apparently not, I'm on WinXP, English, and even though all the hardware is here and seem to be working fine, the eMobile app won't allow me to connect. Pretty simple, the "Connect" button is just grayed out, no way to connect. I tried installing the app both in English and Japanese, both same result. My guess is that the App is looking for the Device with a Japanese name, and can't find it so won't allow me to try. Anyway, nothing you can do, but just letting you know you were pretty talented to get it to work on Ubuntu, and in English ^^ Cheers.
Thank you very much for your post, it was very helpful.
I tried to use the ppp utility but the screen that came out was a bit different, so I could not finish the configuration. Instead I created the file /etc/ppp/peers/emobile with the following information: " user "em@em" connect "/usr/sbin/chat -v -f /etc/chatscripts/pap -T *99***1#" /dev/ttyUSB0 115200 noipdefault usepeerdns defaultroute persist noauth " and I could connect using the command "pon emobile". Hope it can help too. |
