[Freeware] Ubuntu 8.10

Ubuntu is a community developed, Linux-based operating system that is perfect for laptops, desktops and servers. It contains all the applications you need - a web browser, presentation, document and spreadsheet software, instant messaging and much more.

Version 8.10

Ubuntu 8.10 Desktop Edition delivers the features you need for an increasingly mobile digital life, including 3G wireless support and guest sessions that lets users temporarily share computers without compromising security. Ubuntu 8.10 Server Edition consolidates its support for virtualization with an integrated Virtual Machine builder, and brings with it a fully-supported Java stack and support for per-user directory encryption

System Requirements

The minimum memory requirement for Ubuntu 8.10 is 256 MiB of memory. (Note that some of your system's memory may be unavailable due to being used by the graphics card.)

With only the minimum amount of memory available, the installation process will take longer than normal, but will complete successfully, and the system will perform adequately once installed. Low-memory systems may be able to use the desktop CD to install by selecting "Install Ubuntu" from the boot menu to run just the installer, rather than the whole desktop started by selecting "Try Ubuntu without any change to your computer".

The Ubuntu promise

* Ubuntu will always be free of charge, including enterprise releases and security updates.
* Ubuntu comes with full commercial support from Canonical and hundreds of companies around the world.
* Ubuntu includes the very best translations and accessibility infrastructure that the free software community has to offer.
* Ubuntu CDs contain only free software applications; we encourage you to use free and open source software, improve it and pass it on.

Found an USB modem on /dev/ttyACM0.
Modem configuration written to /etc/wvdial.conf.
ttyACM0: Speed 460800; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"

This means that it has found a MODEM.. and the basic wvdial.conf has been written..
Now to edit wvdial.conf

Code:

sudo gedit /etc/wvdial.conf

Enter the Dialling number, Username , Passwd etc

My wvdial.conf :


[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = USB Modem
ISDN = 0
New PPPD = yes
Phone = *99#
Modem = /dev/ttyACM0
Username = b
Password = a
Baud = 460800

Now to connect

Code:

sudo wvdial

If all has gone right it shd show something like

--> WvDial: Internet dialer version 1.56
--> Cannot get information for serial port.
