Access Internet From Mobile Using Computers Internet Connection

Now as with most mobile hacks, this is limited to symbian mobiles which includes almost all Nokia Series60 and Many Sony Ericsson phones.

Why do I need this?

Yep. I felt the same long time back and also left the idea, but our reader Manish wanted to know this. And now I am done with this I am finding this quite useful. I need internet on mobile only to update themes, games and other stuff. Downloading themes, softwares and other stuff on PC and then sending them to mobile is one option but I always find its tedious.

This one is really better as its FREE and speed is much better than what GPRS ever offered!

How it will work?

We normally connect PC and Mobile for file transfer and data synchronization. One step ahead, we use GPRS on mobile to connect internet on PC side. All these means, two devices can connect to each other and share Internet. Only remaining possibility left to check was, can mobile dial/use/access internet on PC?

And here is the solution which will work for sure but may need some efforts…

Requirements…

A PC with internet connection. OS does not matter. Also it doesn’t matter how you connect to internet from PC.
A symbian handset with GnuBox - a free and open-source tool which will do thing on your handset.
mRouter to do things on PC side. Its optional but can save your lots of time. You can manually handle

Now first requirement is obvious, lets take care of the remaining too…

Preparing PC side…

#using mRouter (Windows only)

Windows user can download mRouter. Then install it on your PC and restart the machine.

Next you need to configure mRouter which is quick & easy. Tam Hanna here. explained it very well

#without mRouter

Now all major OS have internet connection sharing feature.

On windows, you need to add a new modem and attach it to COM port which is used fro Mobile-PC communication. As an example check this article for details on how to do it on Windows, Symbian Mobile & Bluetooth channel combo.

Covering all details of other OS is not possible here. Check tutorials section below for a matching reference.

Preparing Mobile side using GnuBox…

Download GnuBox version for your handset models.

GnuBox have a dedicated page here. Do not forget to check it, as it have

For particular instructions for your handset, OS combo, check tutorials from following section.

Tutorials & References…

Official GnuBox page covers most of the details but its not enough for many users. So here is the list of tutorials & references which may help you…

#Windows

#Linux

#Mac

#Misc

#Videos
You can find many vidoes dedicated for gnubox on YouTube. Watch one which best suits for your task.

Thats it. I know it sounds a lot of work! But its worth it…

I have done this on Nokia N70 and using mRouter on Windows XP machine. So I am quite sure it will work. Still if you stuck somewhere feel free to comment…

Fun with GTalk/Pidgin: Changing your status messages programatically

We have always seen people trying to come up with catchy one-liners and cool slogans as their gtalk status messages. On being unable to come up with cool, funky and _original_ status messages to impress friends and colleagues, I decided to put on the programmer’s hat and came up with ways to set these status messages through a simple program. Advantages? Well, enormous. Once you can control the status message string through a program, you can basically rotate it (Rotating status messages do look cool ), update it automatically every 1 minute, write a scripts that ‘copies’ your friends status messages periodically :P… Seriously, the opportunities are limitless and only await your imagination! GTalk status messages can be thought on the lines of a Publish-Subscribe Messaging. To understand this, think of a simple newspaper. It publishes some information everyday and its reader in a way subscribe to this information. In the same way your messenger status message is published by youand it is “subscibed” by your friends. This can be thought of as a kind of Multicasting group. So, as part of this blog, I will basically discuss the Google Talk XMPP protocol and will focus on 2 popular IM that use this: GTalk for Windows and Pidgin for Linux (actually pidgin is multi platform)

Configuring Pidgin (in Linux):

For this you will need libpurple-bin to be installed on your system. You can find this in all common linux repositories. For eg. in Ubuntu, this can be done by a simple command:

$ sudo apt-get install libpurple-bin

Once this is done, we need a simple shell script to change our status message. For eg. the script below, makes the current date/time being set up in the status message in case you are “available” in the format :

Wed Jul 2 13:46:53 EDT 2008

and updates it every 30 seconds.

sleep_time=30
while test 1 = 1; do
msg=`date`
if test "`purple-remote getstatus`" = "available"; then
purple-remote "setstatus?status=available&message=${msg}"
oldmsg="$msg"
fi
sleep "${sleep_time}s"
done

This file can be downloaded here.

Let us call it status.sh

Now what remains is just to execute this status.sh with pidgin running and you are done! The status messages will keep on changing every 30 seconds and I guarantee it will be fun Please don’t tamper much with the sleep time because while you are chatting, your status message is displayed on your friend’s side whenever it is changed. So you can imagine that it becomes quite irksome for your friend to continuously notice your status message change.

Configuring GTalk (in Windows):

Configrung GTalk messages programatically in Windows is a little tricky (another reason to switch to open source linux:) ) . For this, you need to have a Java Development environment in your system as we need to write XMPP application code using a well known API called Smack API which is in Java.

So, first of all, let us start with installing Java on the system (if you donot already have it) which you can get here. Once this is done, we need to get the Smack API which is an open source, pure Java library for working with XMPP (clients only). The API can be downloaded from http://www.igniterealtime.org/downloads/index.jsp#smack. The source code for this can be obtained from http://www.igniterealtime.org/downloads/source.jsp.Just download the appropriate libraries and put the JAR files in your classpath. If you can’t figure out how it is done, please Google your way around or refer this.

Now, we get down on writing the code!

The java file will look like:

// Import appropriate headers and packages
   XMPPConnection connection = new XMPPConnection("gmail.com");
   try
   {
     connection.connect();
     connection.login("username", "password");
     Presence presence = new Presence(Presence.Type.available);
     presence.setStatus("Hello Friends!");
     presence.setPriority(24);
     presence.setMode(Presence.Mode.available);
     connection.sendPacket(presence);
     Thread.sleep(30000);  // Sleeps for 30 seconds
   }
   catch (XMPPException e)
   {
     System.out.println(e.toString());
   }

The thing to notice here is that the argument of setStatus is a String. So, to rotate your status message, just use the following function:

    private static String rotate(String input)
   {
       return input.substring(1) + input.charAt(0);
   }

which takes in a simple string as input and rotates it one character at a time:

eg. CORNELL

ORNELLC

RNELLCO etc.

So, get down to it and Enjoy!

Welcome 2009

Another New Year is coming tonight.Year 2008 has been my toughest year so far I have seen in my life, with lots of things happened around me and finally its coming to an end this brings some relax to me.Those tough and horrible days can't be forgotten so easily with many of sleepless nights.Even such things happened I was staying with my constant mind and was always thinking and daring to beat those.I think I have got a good resistance power to those sorrows but fear to check out my limit as no body wants it.

With New Year coming on its way I hope My Happy Days will return back which I had lost in 2008.Wish you a Very Birth Day 2009...

Smile

It seems like it’s just been yesterday
When I had met you on the way
We laughed and talked all day
But today we are all miles away

You are all in my memory never to be cast away
For we love each other and can never betray
Believe me my friends today
We are actually just smiles away

A smile that I truly mean and also the smile that make me feel lonely even when I am amongst a crowd.
