How to configure airtel gprs in linux .

The first thing i wanted to do as soon as i installed Debian on my Lap was to configure my nokia 6233 which subscribed to airtel gprs (also known as mobile office) to access internet, because i knew if i couldn't i will slowly but surely return to that old boring Windows Xp. So i was determined to do it and was successful in doing so (thanks to the linux community on orkut) after some tweaks and edits. Here is how i did it >>>>>>>>>

Step 1
Connect your mobile to the Computer via USB or serial Cable.

Step 2
#wvdialconf /etc/wvdial.conf

Modem configuration will be written to /etc/wvdial.conf. We will slightly change it to suit our need.

Step 3
Now you should edit the file as follows:

#vim /etc/wvdial.conf

Modify the file as follows [For Airtel]:
[Dialer Defaults]
Modem=/dev/ttyACM0
Init1 = AT+CGDCONT=1,"IP","airtelgprs.com","",0,0
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Baud=460800
ISDN = 0
Modem Type = USB Modem
Username = a
Password = a
Phone = *99#
Stupid Mode = 1

Step 4
Give the following command as root:
#wvdial
When connected, you will see the IP Addresses of your Primary and Secondary DNS servers. Note it down. Disconnect using Ctrl+C.


Step 5
Edit the file /etc/resolv.conf file with your favourite editor and add the IP Addresses you have obtained at the end of the file.

#vim /etc/resolv.conf



Add these 2 lines at the end of the file:
nameserver [IP Address of Primary DNS Server]
nameserver [IP Address of Secondary DNS Server]

Now type the command:
#wvdial
Minimize this terminal & surf with Web browser of your choice like Firefox.
When you see IP addresses of your Primary and Secondary DNS Servers, you are connected to internet. Remember to disconnect using Ctrl+C



Ya thats it, this much steps got me connected to the net through my 6233.........

You might get an error when you use wvdialconf command, if so dont worry. That is because you might not have wvdial installed in your system which comes as a package. I got this same error that is why i can tell you this. So install the wvdial package (i.e by giving "apt-get install wvdial" in the terminal) from the repository( cd/dvd or internet).
All the above tweaks will work only if you are the root in the terminal ( to do this just type "su" or "sudo" in your termonal and give the password)

Let me know if you tried this...............
