Ubuntu :: Dialing Uknown Usb Modems?
Oct 5, 2010
i have all kinds of usb cellular modems i want to try.i used 2 models of the sierra wireless modem, and one ZTE modem. when i connect the usb modem, i see /dev/ttyUSB* (1/2/3..).then, using minicom i can connect to the device and send AT Commands to communicate with it.when i tried another modem, which is not recognized by NetworkManager for example, i couldn't see any /dev/ttyUSB*, and i have no idea how can i send data to the device..my question is:
1) what's the driver role in creating those ttyUSB handles?
2) how can i just write to the usb device, the same like in serial ports for example?
3) so, if i were the best developer in the world, is it possible to communicate with an unknown usb modem? or in any case - i'm depended on the manufacturer driver?

I just installed Ubuntu 10.04 on my Mom's HP laptop. She loves the way I set things up for her. It's a one click solution for accesing her banking, Facebook, Email and SKYPE. I would like to be able to add something else to the panel whereby she would just click once and a telephone pad would appear for her to dial phone numbers so that she can call people from her computer.

In Fedora 14 (kernel 2.6.35.10-74.fc14.i686) I am not able to get an internet connection on my laptop via mobile broadband. However dialing succeeds and the provider starts the daily flate rate accounting.I tried the graphical network management as well as wvdial and even sakis3g (achitecture free variant from URl...).With wvdial (well configured I think) and sakis3g the dial connection is established (permanent blue light on Huawei E169). "netstat -ie" shows that the network configuration has changed (device pp0 instead of eth0 and "netstat -rn" shows that default router is set to 10.64.64.64). But "ping" does not receive data from any internet IP address and browser cannot render any website. A later check call of my prepaid balance said that the daily rate countdown was initiated (so I pay for nothing).
The GUI of the KDE network icon seems to work similar but does not set the usb key into the connected state (only blinking blue light and break-off after a few seconds).Disabling of selinux didn't change anything as well.With Mandriva 2010 I didn't have any problems with same mobile key and provider.

I am moving and am having AT&T DSL set up at my new place.. It is going to be set up next monday and I opted to not purchase their DSL modem (I wouldn't be there when it would be delivered and it would have been stolen most likely) So, anyone know of a DSL modem compatible with AT&T DSL that will work that I can pick up at a chain store? Wal-Mart, etc...

I would like to say first and foremost that I have tried to lookup what I can find about this thing I am doing and most of the time all I have found are either un-replied posts or vaguely explained answers but here is what I want to do.I want to setup a small gateway for my new office using two 3G internet providers offering Huawei usb modems. So I would like to have two internet links active per time and have one LAN consuming from the two links. I have seen the phrase Load Balancing all over the place but they all show their examples using ethernet and static IP's. My providers give DHCP ip addresses so is there anything I need to know and can anyone point me in the direction of some tutorial or howto i can follow to do this?

Q: How can I use at the same time two ADSL USB modems with pppd and pppoatm.so plugin?
I have the following scenario:
- Two ADSL USB modem correctly recognized by Linux.
- pppd configured with two different files, one for each ADSL (even if the two ADSL have the same parameters). Those files are /etc/ppp/peers/adsl1 and /etc/ppp/peers/adsl2
If I attach only one modem and then launch "pppd debug call adsl1" or "pppd debug call adsl2" everything works fine.
If instead I attach both modem in order to have two ppp interfaces, ppp0 and ppp1 I get the following behaviour:
- When launching "pppd debug call adsl1" the first modem connects correctly.
- When launching "pppd debug call adsl2" I get:
connect(8.35): Address already in use
That's because either adsl1 and adsl2 are trying to use the same modem.
So the question more specific question is: How can I specify which USB modem to use in pppoa ADSL connections?
With dialup modem it is possible to specify /dev/ttySx in peers files, but what about ADSL USB modems?

I'd like to use one of the popular USB wireless modems for Internet access. If Linux supports this, I assume that the required driver is in the kernel, and that connection would be automatic. Has anyone had experience with this?

I am looking to buy my own unlocked/never-locked mobile broadband modem, and I want it to work well on my 64-bit 10.04 Ubuntu system (triple-booting MacBook 4,1). Is there a list of mobile broadband modems supported in the linux kernel out there somewhere? I did try to find one myself, but no luck. The Huawei E220 looks good, but it is discontinued.

I tried to use multiple mobile broadband modems in ubuntu 10.10 and encounter a bug as follows:
When i plug in a new modem, all the attached modem is automatic go offline ( thus my connection is down), and try to redial back, sometime the redial is successful, sometime it's not.
It was working fine in ubuntu 9.10, plug in a new modem, all attached modems stay connected.

I'm new to Linux, so I decided to try using Wubi to get started. THe problem is, when it finished installing 10.04, I got this message: OSError: [Errno 13] Permission denied: u'C:\ubuntu\install\ubuntu-10.04-desktop-amd64.iso' Is there any way around this? It might just be that overly restrictive thing called Vista (which I have the bad luck to be using). I was considering getting a USB drive for Ubuntu anyway..

What is the difference between the Ubuntu Installer for windows and the Ubuntu CD image? If I use the ubuntu installer for windows, does it have the capability to partition my drive, will it enable to share files with windows etc or is it just a way not to have to burn a CD. Just curious, the exact details of the installation files were not made clear on the website. Note: Windows Version: XP, 32bit, SP3. I have not partitioned anything yet.

I have windows 7 installed on Disk2 (according to windows Disk Manager), and I installed ubuntu 10.10 on Disk0, choosing the dual boot option at installation.
However, grub does not load (presumably because its on disk0 and my machine appears to boot from disk3), so the machine goes straight into windows 7.
How do I get ubuntu to load?

I'm currently running off of my live-cd, and after spending 4 hours of my life trying to fix this myself, i figured someone out here has to know how to help me. Basically, i wanted to try linux, then liked it enough to decide to put on one of my usb-drives (320g adata nobility NH92), and i couldn't get it to boot anything but windows w/o the live-cd, which would then boot the live-cd, lol, in other words, i couldn't get it to boot at all from the external, even though i had changed the setting in my bios to boot from usb first, and tried manually selecting boot from usb and all that fun stuff.
Sooo... eventually i decided it might be a problem with the bootloader, and while i'm not exactly sure at this point what i have done to my computer, all i can successfully boot is the live cd. When I try to boot w/o the live cd, whether i try to boot from my internal (windows) drive, or external, all i get is a device not found error.I think i could fix it if i had windows recovery cd's (i'm running xp, btw), or installation cds, but... unfortunately, they died in a terrible accident. So i have no cd's at all for windows. :/

I have been running Ubuntu 10.04 under Windows 7 (Is this call WUBI?) without any problems for a while. My other machines only run Ubuntu (9.04 & 10.04). I decided to give it a try to the latest Ubuntu 10.10. After going through the successful installation and then rebooting, I am getting the following error message once I select 'Ubuntu' in the boot up menu right after the BIOS screen: Booting ' Ubuntu 10.10, kernel 2.6.35-25-generic'

I'm wondering if this is even possible. I've searched high and low and have yet to find and answer to this particular setup.
The setup:
Router is in another building.
Desktop connected by WiFi
Laptop connected by WiFi
Both the Desktop and the Laptop are in the same building together. About 5' apart.
SSH server is setup on Desktop
FreeNX client is setup on Laptop
So they can connect just fine via WiFi for remote desktop control of the Desktop from the Laptop (so SSH and FreeNX are working).Is it possible to connect the 2 pc's directly to each other by Ethernet cable AND transfer files between them by Ethernet while still being connected to the Internet by WiFi on them both?Or would the WiFi have to be disabled while using the Ethernet connection?Neither has a Gigabit Ethernet NIC so I know it would at least require a crossover cable or another router to connect the 2 by Ethernet cable.The idea behind all this is to be able to transfer files between computers quickly by Ethernet while the computers are still busy doing other things on the Internet by WiFi.

1. I accidentally wrecked a previous Ubuntu installation so I decided to re-install via the Ubuntu disk. Unfortunately Ubuntu doesn't let me override previous Ubuntu installations...
2. Ubuntu Maverick Meerkat is due to released in about 3 weeks. I want to install it via a clean install.
3. So can anyone tell me how to remove both Ubuntu partitions safely. I am currently running WinVista with Ubuntu Lucid Lynx. I know I have to use something like this to erase GRUB2. Can anyone give me a good tutorial?

The scenario is as follows - I will be moving across the country and my desktop will stay here powered and online, while I move with a laptop. I need a way to connect to the desktop for file streaming(music and movies) as well as using the virtual machines. I have thought about SSH and VNC.I need something failsafe. That's priority one. I won't be around to fix it if it breaks. I can set the computer to come on in the BIOS at a certain time if the power went out. But if I can get in remotely the whole setup is useless.SSH only provides terminal use, correct? So if I chose that route I would be able to access the computer via command line and play music and movies with mplayer and such, correct? But I would not be able to run the virtual machines? Because there will be no GUI, right?
I have been playing with Vinagre and Vino through the host and guest of a virtual machine and I cannot get it to connect. Is there a better application? x11vnc? I have forwarded port 5900 on the router and have upnp enabled. Got a better remote desktop suggestion?I would like to run this setup headless.(no monitor) I also would like to run it without a gpu if that is possible to make it more energy efficient.Both computers are 64 bits and will be running Ubuntu 10.10 and soon 11.04.Are these crappy ideas to begin with? Should I go another route to get my files and access the virtual machines?

After a reinstall of 10.10, I am able to turn on file sharing and so I set up a shared folder.
Windows Vista can see this folder but in my network place, there is only one icon, and it's a "Windows Network" icon. Upon clicking on that, I can see the local network, "Rompus Room".
When I click on Rompus Room, nothing happens for a while, then I get a message saying, "Opening "ROMPUS ROOM". Then I get the final message, "Unable to mount location", followed by, "Failed to retieve share list from server"

I was running 9.10 in LiveCD mode and was unable to get online. Went to System>Administration>Hardware Drives and found "Broadcom STA wireless driver". Cool. So I went ahead and installed 9.10 (dual boot with Vista), repeated above steps but found no "Broadcom STA wireless driver" option, in fact no proprietary drivers. So I still cannot connect to the Internet, and I don't know where to go from here. (Note: I installed 9.10 side by side with Vista: good? bad?)
