BSNL EVDO setup in linux...

ubuntu :
i used the wvdial tool to setup the modem...
type the following commands,

#sudo wvdialconf

Enter the administrator password. The modem settings will be written in the file /etc/wvdial.conf .


 #vim /etc/wvdial.conf

use any editor and enter the username password and phone no in the aforementioned file.

then save it.
the file will look like :

[Dialer Defaults]
 Init1 = ATZ
 Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
 Modem Type = Analog Modem
 ISDN = 0
 Phone = #777
 Modem = /dev/ttyUSB0
 Username = **********
 Password = **********
 Baud = 9600
 Stupid Mode = 1

Now type,

#wvdial

the output :

--> pppd: �Ť[08](Ȥ[08]
--> pppd: �Ť[08](Ȥ[08]
--> pppd: �Ť[08](Ȥ[08]
--> pppd: �Ť[08](Ȥ[08]
--> pppd: �Ť[08](Ȥ[08]
--> local  IP address 117.254.223.55
--> pppd: �Ť[08](Ȥ[08]
--> remote IP address 192.168.52.12
--> pppd: �Ť[08](Ȥ[08]
--> primary   DNS address 218.248.240.134
--> pppd: �Ť[08](Ȥ[08]
--> secondary DNS address 218.248.240.181
--> pppd: �Ť[08](Ȥ[08]

This was my output but something of this sort shows that u are connected.

NOTE: instead of #sudo wvdialconf  we can directly copy the file details in /etc/wvdial.conf

Enjoy..

installing wvdial package in ubuntu 9.04

At first I downloaded the following packages (from a pc connected to the internet, any O.S.): 1. http://packages.ubuntu.com/jaunty/i386/libxplc0.3.13/download 2. http://packages.ubuntu.com/jaunty/i386/libwvstreams4.4-base/download 3. http://packages.ubuntu.com/jaunty/i386/libwvstreams4.4-extras/download 4. http://packages.ubuntu.com/jaunty/i386/libuniconf4.4/download 5. http://packages.ubuntu.com/jaunty/wvdial/download Note that above are all for an i386 pc. I copied all to a USB memory stick, and then paste them to the ubuntu 9.04 running pc into /var/cache/apt/archives/ directory using sudo nautilus from terminal. Then I installed all packages by double clicking each icon (of .deb package) in above order (1,2,3,4 and finally 5). I ignored all informative messages. Finally I had to run wvdialconf, edit the /etc/wvdial.conf file and be connected with sudo wvdial. You can get my wvdial_904_i386 zip file (size=1.04 MBytes) containing all above. Into .zip file there is a .txt with checksums. Please CHECK all files and do it at your own risk.
