hi all,

we know that .. in todays our pals are facing much problem in connecting to internet in Linux using modems.The following will let you learn how to connect to internet using your GSM mobile and the GPRS connectivity.

Before starting i will tell you my system configuration

— Intel 2.66 AM64T on Intel 915 GVW, 512MB RAM, 160 GB HDD

— Ubuntu Edgy 6.10 + Gnome

— Sony Ericsson K320i

So here we goes….

Step 1:

First connect your mobile to your system through the USB connectivity.

And chose the option “phone mode” (If its available)

Step 2:

Now its time to configure your mobile, Open a terminal and login into root account there.

$ sudo su

# wvdialconf

ttyS0<*1>: ATQ0 V1 E1 — failed with 2400 baud, next try: 9600 baud
ttyS0<*1>: ATQ0 V1 E1 — failed with 9600 baud, next try: 115200 baud
ttyS0<*1>: ATQ0 V1 E1 — and failed too at 115200, giving up.

ttyACM1<*1>: ATQ0 V1 E1 — OK

ttyACM1<*1>: ATQ0 V1 E1 S0=0 &C1 — OK
ttyACM1<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 — OK
ttyACM1<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 — OK
ttyACM1<*1>: Modem Identifier: ATI — Sony Ericsson K320
ttyACM1<*1>: Speed 4800: AT — OK
ttyACM1<*1>: Speed 9600: AT — OK
ttyACM1<*1>: Speed 19200: AT — OK
ttyACM1<*1>: Speed 38400: AT — OK
ttyACM1<*1>: Speed 57600: AT — OK
ttyACM1<*1>: Speed 115200: AT — OK
ttyACM1<*1>: Speed 230400: AT — OK
ttyACM1<*1>: Speed 460800: AT — OK
ttyACM1<*1>: Max speed is 460800; that should be safe.
ttyACM1<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 — OK
ttyACM0<Info>: Speed 460800; init “ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0″
ttyACM1<Info>: Speed 460800; init “ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0″

Step 3:

We will be getting the similar output as above…. when we wvdialconf

So after we need to identify at which port (or the device) the modem is identified. That can be found out by identifying the line

“ttyACM1<*1>: Modem Identifier: ATI — Sony Ericsson K320″

and now open the file /etc/wvdial.conf

# gedit /etc/wvdia.conf

It will be looking like

[Dialer Defaults]
Modem = /dev/ttyACM0
Baud = 460800
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
ISDN = 0
Modem Type = USB Modem
; Phone = <Target Phone Number>
; Username = <Your Login Name>
; Password = <Your Password>
New PPPD = yes

So in the above code we need to make some changes as per your mobile. Since the mobile is pointing to modem = /dev/ttyACM0, where as the wvdialconf returned /dev/ttyACM1 as the modem as shown above. So change the line “Modem = /dev/ttyACM0″ in the /etc/wvdial.conf to  “Modem = /dev/ttyACM1.

And we cant just keep the other fields empty, so just dial your service customer care center and find out the dial up number for your GPRS-Internet connection. And ask for any username and password (if they exists for your GPRS service). Fill that fields in the /etc/wvdial.conf accordingly.

If you are not having any username and passwd … wvdial will not allow you leave those fields empty, so just fill them with your own data like

Username = bob

Password = crank

And be sure to keep the following line, if you are not having any username and password.

Stupid Mode = 1

Once you are sure that you, configured your wvdial fine. You can dial-up your GSM modem by following.

wvdial

and you will be given your IP address and the server IP address displayed. You can hang the connection by just pressing the CTRL+C.

Hope you got it well.

Later.

INTERFACE 2K7,

Huh, when i first heard about this i thought this will be really rocking. But it took lesser than 12 hrs to realize that i have been thinking wrong, not just wrong but bitterly wrong. First lemme come up with the details of paper presentation.

NAME: Interface 2K7

Venue: Deparment of EIE, GITAM, Vizag.

Date: 01-03-2007 and 02-03-2007

From my earliest days of Engineering i had just imagined .. in such a way that it would be the best suitable college for engineering. I once had a cocktail view of gitam when i came to vizag for a tour. And seeing it in the middle of the slopes of the hill, i was really impressed, and from that days i have had few imaginations how the college will be.

When i first stepped in the front gate of the college, again i am bitterly wrong. <LOL> It’s much beyond, to my imagination. I was quiet impressed. And thought this would be my best paper presentation i have ever done. We entered the premises of the college with a lot of joy and enthusiasm. We headed to the registration center to get our names registered. Here we were given the first blow…

We had 3 members i our team and we were asked to fallow the IEEE standards in the submission of a paper. And our members are from different colleges. We were objected, since we are the combination delegates from different colleges. EVER HEARD THIS TYPE OF OBJECTION AT AN IEEE STANDARD PAPER? Its really pityful. And the registration fee is Rs.250/-. Dont think that this fee is for the paper, but this is for an author. What a kind…ok we never bothered in paying quarter a grand, since we will be given .. facilities like that pay only. I wish you should have seen the bag and stationary they have given us for attending the presentation (may be for paying 250 bucks). And some how we have been got in, and we were asked to gather at session hall at 1.30pm and the lunch is at 12.30pm. We have had lunch at 2.00pm and even the session started at 2.45 hardly. Hmm coming to the presentation, a very dull starting, anchoring reflects how careful they are in conducting the event. The very dull anchoring i have ever seen. But i am glad about the event coordinator there. At least they cared a bit for us. Another pitiful thing is about the judge. Generally a national level event will have the judges at least from .. out side the college. But its really disgusting not even from the another department of the same college … but same department .. Asst. Professor is our judge. We are on a bit of shock. Huh.. lemme come worth a sense of irony, he dont even knew what a MAC (Medium Access Control) but he is the judge for CSE category. Its really … (no words to express).

A part from this, from GITAMS  – Interface 2k7 i learned one thing. Never expect any thing due its reputation or .. status .. just believe in how much capable they are. Where i felt .. interface 2k7 is a Damn failure. Though the people there are extraordinary. They really need to understand this.

Hope they would be careful even in the future.

Sorry for bothering, Thanx for your time.

Waiting for your coments…..

Later.

Do you ever think about your first program written in your first computer language?

Let me take consider that a child who learns C language will start his first program with this “Hello World !”
#include<stdio.h>

main()

{

printf(“Hello World !“);

}

Is this …???

But have you ever think …… in any of the languages this is the first program you will ever learn ..is it n`t it?

There lies the real thing…..in the ancient days of computers there are not that much no of people who learns computers and those who have knowledge about computers and their programing.

So how do they share their knowledge … they chat on-line…but in those days there are nothing yahoo messengers or any thing…but there is something like IRC.

Why to use IRC rather than Chat rooms

IRC includes a lot many no of of servers and channels. Some channels are official and the others are not. And there are lot many servers few of them are… irc.freenode.net, us.undernet.org, like wise there are a lot many no of servers. And freenode is being prefer by a lot many no of communities as their official channels.

Practical usage of IRC

We need something like IRC client to use IRC. It just like yahoo messenger is needed to chat in y! network. So there are a lot many number of clients like .. mIRC,XChat,gaim etc. The preferred client is xchat (if you are using windows you can download it from here otherwise for GNU/Linux machines just type “sudo apt-get install xchat”)

first open of xchat ..

There is no need for the user account in IRC. Just give your nickname (nick), real name, server (you can edit a server list by clicking “Edit” shown in above pic. Generally the channels (for the sake of IRC lemme call the chat rooms as channels) starts with a “#” like ….

a channel “#c” will be involving the discussions about c-language

So some example official channels are #ubuntu, #fedora, #c++ etc.

There are also some specialised channels like

#ubuntu-in (Ubuntu activities in India)

#ubuntu-ap (Ubuntu activities in AP)

For example take server as “Freenode” and press connect.

Once you press the connect you will have the look like bellow

So you can fill that join channel by your own channel … or you can also have a look over all the channels that are available. I will join the channel #ubuntu and press OK, then

The right side list is the “nicks” of all the people who logged in the channel #ubuntu. And the text bar you can see at the bottom is to type the text that you want to send.

More usage in IRC

Some of the channels like #fedora,#java says that you must be recognised to enter the channel. This means to register your nick such that it will not be used by any other. To register your NICK .. first you should confirm whether the NICK is already registered or not … we can get it by typing

/msg nickserv info sandy16

>nickserv< info
-NickServ- Nickname: Sandy16
-NickServ- Registered: 28 weeks 6 days (5h 3m 24s) ago
-NickServ- Last Seen: 5 hours 23 minutes 40 seconds ago
-NickServ- Last Seen Address: n=sandy@202.133.63.17
-NickServ- Last Seen Quit Msg: “Leaving”
-NickServ- Nickname Options: Secure, AllowMemos, MemoNotify, MemoSignon

Lets try the info command for the nick “sandy16aa”

/msg nickserv info sandy16aa

>nickserv< info
-NickServ- The nickname [sandy16aa] is not registered

So if we want our nick to be registered, first set your nick to the nick you want and type the following command

/msg nickserv register yourpassword

So the message will be displayed once you register

Q. Do i need to register every time i login?

No, once you register your nick enough. From the next time you need if you need to identify your nick then

/msg nickserv IDENTIFY yourpassword

So once you type this .. you will be displayed a message saying you are now recognized.

Q. Do i need to type this much long command every time i need to identify?

No, you can set the automatic login to the user at the very first picture of this discussion, click the Edit button there. You will see the well defined options. Hope you will understand.

Q.Can I join another channel while a channel being opened?

Yes. Just type the command of joining a channel

/join #fedora

or

/j #fedora

You can even set the list of channels separated by “,” in the Edit menu of the very first pic. So when ever you login these channels are automatically joined.

Q. Whats if I dont have a IRC client and i am unable to install any client.

That will be not a problem, when you don’t have an IRC client.Because there are plenty of IRC portals in the web. It means that they will be connected to IRC using the browser. Some of them are fallowing..

1) http://ircproxy.emigrantas.com/

2) http://gogloom.com/FreeNode/ubuntu-ap/CHAT

But the second link runs using JRE, the client system need to have the Java Run-time Environment, this can be downloaded from here.

A Last reminder …..

The IRC has a specific regulations … so please follow them to get a good results of its usage.

So hope you would join explore the world of sharing knowledge … i,we, every one call it as IRC.

Waiting for feed back

Later.

Hi this is Sandeep. I am an Ubuntu Tuxian. As this is my first blog i wanna share some of my feeling with you people.

First of all let me start with a quote “Human Knowledge belongs to world ” . I know lot many of you people will agree with me. Is n`t it?

Whats if Sir Isaac Newton has copyrighted his works on the gravity principle he made….i am really afraid to say whether there would be any person like Albert Einstein or some body. Really….I a person had ever hide their knowledge how is the world going to survive any more…

There started a revolution against those who put the barrier against the humans and their knowledge…..its started by….Richard M Stalman (RMS) and named a free software foundation so here starts the game…
