基于kppp的 GNU/Linux & GPRS Howto

Linux is a powerfull operating system even on the SOHO (Small Office Home Office) front, where the  potential is much more than we could imagine only if its used the right way.

Especially it has been proven to be the.. reliable soft in the server front even then I had a tough time to figure out howto connect my GPRS cellular phone thru serial cable with my Laptop running Linux OS to browse the web on the move.

Finally after months of fiddling and reinstalling the same OS again and again since I was playing as God (I meant as user root)

 

at last It just turned out to be a simple setup without any pain or whatsoever.

 

Please take your time and understand the steps provided below ....

 

O.K.

Lets begin!

 

Any Distro (Fedora, Kubuntu,Mandrake, Debian, etc..etc..)would do..

Now click the menu button select internet and then dialup tool (KPPP)

You will be presented with a GUI ( Graphic User Interface) like the one shown below.

 

Step 1.

Now the simple setup procedure.. On this GUI click

configure

or press 'n'

 

Step 2.

You will be presented with this GUI and here you will have to create a account.

That is !

Your Internet Service Provider's Details.

 

Click new..

 

 

 

 

Step 3.

 

1.

In the 'Connection Name' Dialog type any name you prefer to call this connection

 

       Where I have used the name "My Connection"

 

2.

In the authentication dialog click scroll and select "PAP"since most GPRS connections dont need passwords

 

3.

For the Phone Number click Add and enter the GPRS (ISP) Number

Which will be either  *99**1*1# or *99*1*1# or maybe something similar.

check with your Service provider

 

  

Step 4.

 

Here Only 'ONE' entry

 

In The Domain name Box Add your ISP Server Name

 

Which will be     " Something.com"

 

If you are not sure find out from your Internet Service Provider.

 

 

Also the Configuration dialog should be left at "Automatic" not manual.

If it's left in manual position you may get connected but you will not be able to access internet.

Your Browser will report " DNS Error"

 

(Ps:  If you are not able to click Automatic here, Please start KPPP as root )

 

Now Press the 'OK' button

 

 

Now your phone dialer settings are done the Next thing is setting yor phone as Modem

 

Now click the 'Modems' Tab

And Click New

and DEVICE tab

 

 

Modem Name        : Anything you like

 

Modem Device        : If Serial ( COM 0) should read

                                /dev/ttyS0

 

Flow control        : Hardware (CRTSCTS)

 

Line termination  : CR

 

 

Connection speed should be 115200 not more not less

because most GPRS phones are preset at that speed.

if you change the speed which the phone dose'nt support the Modem will not respond.

 

Dont change anything else

 

 

Click Modem tab

Here you dont have to do anything except untick the

'wait for dial tone' or press W

Thats it !!!

now click OK.

 

 

Now you will back to the Connect Screen

Here you enter your Mobile Number in the Login ID dialog box

Congratulation now you are almost done..

 

 

You must be eager to CONNECT Please wait there are

Two more small steps before you can press the CONNECT button.

Now open a Konsole window (terminal)

su:

password:*********

 

now type

 

# kwrite /etc/ppp/options

 

       wait till the text editor open

       and then type into.. exactly as written in blue.

 

       /dev/ttyS0

       115200

       noauth

       noipdefault

       nodetach

       local

       usepeerdns

       ipcp-accept-local

       lcp-echo-failure 30

       lcp-echo-interval 4

       lock

 

       save file and exit.

       and next in the Konsole window type

 

# kwrite /etc/resolv.conf

 

       wait till the editor open

       and type nothing, just savefile and exit

       if it says file exists asks whether to overwrite press skip

 

Thats it now CONNECT and ENJOY the World Wide Web
