    Re: no more problems with your..mDSL

    So, giving up on the above methods, I reinstalled Ubuntu (for about the nine zillionth time) and dutifully entered all the data above into wvdial.conf file...

    This time I changed directory to root and logged in there. I ran wvdial mdsl... and it works... but only as root.

    And that is, of course, the bug.

    Ridiculous.

    put : Sudo before command to run it as root

    Re: no more problems with your..mDSL

    Here is the solution:

    As Netcowboy has it:

    PHP Code:
    sudo gedit /etc/wvdial.conf 
    Then edit to:
    PHP Code:
    [Dialer Defaults]
    modem = /dev/ttyUSB0
    Phone 
    #777
    Username =sudani
    Password 
    =sudani
    New PPPD yes
    [Dialer mdsl]
    Stupid Mode on
    Modem 
    = /dev/ttyUSB0
    Baud 
    9216000
    Init 
    ATZ

    Phone 
    #777
    Username sudani
    Password 
    sudani
    New PPPD yes 
    Now as root:

    PHP Code:
    sudo -s
    wvdial mdsl 
    Now you have internet.

    Get Gnome-ppp.

    Send the gnome-ppp icon to the desktop. Right click it. Select properties. A window will open. In the command space type

    PHP Code:
    gksu /usr/bin/gnome-ppp 
    Close the window.

    Open gnome-ppp. It will ask you for root password...

    Bingo!

    It works.

    Many thanks netcowboy...

    Re: no more problems with your..mDSL

    Here's some of my system:

    One physical hard disk dedicated to Windows XP Professional; a second physical hard disk dedicated to Ubuntu. Both HDDs are 75 Gb.

    Seem to be having quite a lot of hang-ups on restart or close down out of Ubuntu 8.10,causing me to have to hard reboot to get back in.

    Also, some screen artifacts on Firefox and Thunderbird start up (momentary screen flicker and bars), although I am running the correct drivers for my graphics card (NVIDIA 173 for GeForce FX 5200).

    I shall reinstall the graphics drivers and see if this clears things up.

    SOLVED:

    The graphics card is not keen on the "Extra" setting under System -> Preferences -> Appearance [Tab: Visual Effects]

    As for the Restart/Shut Down hang-up, this seems to be due to the system attempting to restart/shut down before the modem has completely disconnected. I shall write a little bit of code to flag the system to wait until this task is completed before shut-down is instigated. Windows manage to do this, so should Linux... when done I shall post it here.

    Re: no more problems with your..mDSL

    Sorry to hijack this thread, but I wonder if folks could tell me how mDSL works technically? I'm trying to set up a machine for use by someone in Sudan but I'm not there so I'm having to do it blind (afraid it's XP, I was going to install Ubuntu until I discovered that it wasn't wifi and got scared that I wouldn't be able to sort it out over the telephone).

    Summarising for anyone who happens to be reading this, I've managed to figure out mDSL is:
    EVDO over CDMA, network infrastructure supplied by ZTE
    USB connection uses a ZTE dongle - comparing pictures I think it's an MG478 or AC8700
    Dongle first appears as a mass storage device, installs drivers into Windows automatically from that, and then switches to being the network device, which appears to be ID 05c6:6000 Qualcomm, Inc.
    Setup in the host OS is very similar to 3G GSM dongles - in other words not too different from an old dialup modem
    NTC applies filtering for pornography but not (it is claimed) political content


    What I'd like to know is the network environment:
    Is there NAT? Do you get a global IP address (ie not 10.*.*.*, 192.168.*.* or 172.16-31.*.*)
    Are there any proxies that must be used?
    Any ports inbound/outbound that are blocked?
    What sort of bandwidth do you get up and down (I'm interested in central Khartoum)?
    What sort of latency (ping times etc)?
    Do things like voice over IP work? (what programs - Skype, Google Talk, other SIP?)


    Is anyone able to fill in some details? Thanks!
