Sharing files between two ubuntu systems through local router

I have a old desktop running Lubuntu 11.04 and it is connected to internet through a wireless router. While I store lot of information on this computer, I also have a laptop running Ubuntu 11.04 that I most of the times work on and it is also connected to internet through the same router. Transferring files between these two machines is important to me. There are countless ways you could do it, but I preferred ssh to have a safe and reliable connection through the local router. If you are willing to do the same then here's how you do it.



Step 1: Install ssh on both the machines. Run this command in terminals of both the linux machines.


sudo apt-get install ssh

Step 2: Learn the IP address of your desktop. This can be done by right clicking the connection icon on the panel and then on "Connection Information".

Otherwise you can just run the following command and read for "inet addr:" field.


ifconfig

In my case, it is 192.168.1.3.



Step 3: Go to your laptop. Find "Connect to Server" option.

If you are using GNOME then you find this on "Places -> Connect to Server".

If you are using UNITY then you find this option by opening Nautilus. Go to File -> Connect to Server.

You get this window -




Step 4: Fill details into the fields and click Connect.



Service type must be selected to SSH.

Server field takes the address of the computer to which you want to connect to.

Port is 22, which is a TCP standard for SSH Connections.

Folder that you want to share.

Username to access the desktop.

You can add a bookmark and give it a name for you to access it next time.


Step 5: Once you are done, click on "Connect". It prompts for password. Enter it and you are done. You have successfully established file sharing from your desktop machine to your laptop machine. You can do the vice versa by following Step 3, 4 and 5 on your other machine.



PS: I have used terms 'laptop' and 'desktop' everywhere. But this need not be the case and procedure is same for any two machines connected through same router. 

How to install Kernel v3.0 on Ubuntu 11.04

Kernel v3.0 is out there and will be released with Ubuntu 11.10 and yet, there are no kernel updates for Ubuntu 11.04 after Kernel v2.6.38. If you are very eager to install kernel 3.0, then you can build them directly from the source code. Or just use the packages that are used to install Kernel 3.0 on Ubuntu 11.10. Since the latter approach is simple and easy, I will mention step by step instruction to install Kernel v3.0 on your Ubuntu 11.10 Natty Narwhal.

Step 1: Download the debian packages from here.

For 32 bit users -






1. linux-headers-3.0.0-0300rc2_3.0.0-0300rc2.201106081532_all.deb
2. linux-headers-3.0.0-0300rc2-generic_3.0.0-0300rc2.201106081532_i386.deb

3. linux-image-3.0.0-0300rc2-generic_3.0.0-0300rc2.201106081532_amd64.deb

 
Step 2: Once you have downloaded all the files, place them into a single folder. Browse to that folder from your terminal and then copy paste the following code into the prompt.
sudo dpkg -i linux-*

The execution will continue to install kernel 3.0 on your Ubuntu 11.04. Just in case kernel 3.0 mess up, do not remove previous versions. You can always choose from the previous versions in the grub.

If you have or happen to install this, then please comment on the power consumption and other pros and cons of kernel 3.0.

How to jailbreak iPod touch?


There are so many tutorials and videos out there that teach how to jailbreak ipod touch and iphones but the techniques have improved way too much and here is the easiest way which is just a  matter of two clicks to get your iPhone or iPod touch jailbroken. If you are not sure what jailbreaking is then go to the wikipedia page to know more about it.

Why would anyone want to jailbreak his device?

There are a number of reasons. Jailbreaking is similar to rooting your android phones. Jailbreaking gives you much more control over your device. For example, iOS does not by default allow you to change the wallpaper or the theme. But jailbroken devices do.

Here are the assumptions that I've made -

You have a iPod touch or an iPhone running firmware 3.1.2.

Steps follow -

1. Download Blackra1n for your firmware from here - http://blackra1n.org/download-blackra1n/

2. Start the blackra1n.exe

3. Your device will be automatically detected. Just click on the only button that blackra1n.exe provides. Wait for a few minutes and your device will reboot.



4. When your device reboots, you will find a new icon called blackra1n in your device. Open it. Connect to the internet. Download 'Cydia' Installer. Once you're done there will be another icon on your device called 'Cydia'. Using this installer, you get to download lot many applications to your iphone!



This is how you jailbreak a iPod touch or iPhone :) Hope that helps.

PS: There are other ways of jailbreaking a device. This method involves using blackra1n. There are other jailbreaking agents like redsnow, snowbreeze etc. But I personally like blackra1n for its simplicity.

Format from FAT32 to NTFS without loss of data

FAT32 is a file system supported by all operating systems. FAT means File Allocation Table. This provides maximum partition size of 32GB. Disk Quota management is not possible using this file system and the main problem here is the read mechanism. There exists sequence read mechanism under FAT32 and hence the transfer speed of data is very less. This reduces the performance of the system.


NTFS is a new file system and this is supported by all operating systems as well. NTFS means New Technology File System. This provides maximum partition size of 2TB which is very very large. There exists Disk Quota management feature enabled so that the disk can be used to store specified amount of data only. This file system provides Enhanced Binary Tree architecture and hence the transfer speed will be very very high and performance increase as well.


But the main problem is how to change the file system format from FAT32 too NTFS without erasing  the data in the drive?


Techspace has an answer for this problem and the solution is very very simple.


Steps to convert from FAT32 to NTFS without erasing the data.




  • Go to command prompt.


[stextbox id="grey"]convert C: /FS:NTFS[/stextbox]




  • Enter the above command in command prompt and wait till the process completes. After the process is completed, the specified drive will be converted to NTFS without erasing your data on the drive.



  • In my case, C: is the drive which i have taken into account. If you want to format your drive, then you can specify that corresponding letter.



  • FS: means File System.



  • convert will convert that corresponding drive to NTFS without erasing the data in that drive.

    India's 35$ Tablet finally announced. Named Aakash

    Indian government's venture to create the cheapest tablet for students has finally been released. The much anticipated tablet is being manufactured by DataWind Ltd..

    Government aims to provide 10000 tablets to students of India. Cost of each tablet is announced as Rs.2250 and is said to decrease in the coming days when Indian Government places an order for mass production of this. DataWind's Aakash is only for students and the price is subsidized. DataWind plans to release another version of Aakash, called UbiSlate which will be priced slightly higher than Aakash. DataWind claims to deliver UbiSlate by the end of November.

    Ever since the announcement of 35$ Tablet, the processor speed was kept undisclosed. The processor speed turned out to be only 366Mhz. Considering the price of the tablet, this must not be disappointing as it is a value for money tablet. Here is a list of specifications to wrap up.

    Aakash features -

    a 7" display with resolution 800 x 480 pixels

    a 366Mhz Processor

    256 MB of RAM

    2GB of internal

    expandable up to 32 GB through microSD slot

    1 standard USB 2.0 Port

    Wifi Capability

    Battery that lasts 3 hours and

    runs Android 2.2 Froyo

    Evidently, the tablet will not support HD graphics but the product is quite good for what it is aimed at. May be a disappointment to few people, but this is what you get for what you want to pay.

    35$ tablet to be available from October 5th

    Kapil Sibal, the Union resource minister of Human Resource unveiled the 35$ tablet on 22nd July 2010. Since then, techspace has been keeping track of the latest happenings regarding this cheapest 35$ tablet. The Government also announced a subsidized rate of Rs.1100 for students.



    The 35$ tablet will be launched officially on October 5th. The device features a 7"  Touch screen, 2 USB Ports, 32 GB Hard Disk, 2 GB RAM with Video conferencing and multimedia capabilities. The tablet runs Android OS but the version is unknown. There has been no news on the processor speed and continues to remain a mystery until October 5th. The name of the tablet will be revealed on the day of launch. The tablet was supposed to release in the month of June but the tender with Manufacturers, HCL was cancelled causing the delay.

    There are a few expectations on this tablet. If proven good, then this may bring lot of changes in the Indian education system.
