Command Line Package Management [Debian Based]

you can use ‘apt-get’ tool to manage packages via the CLI instead of using the GUI. ‘apt-get’ can be used to install and uninstall packages as we needed. For your convenience Im going to introduce another CLI tool , ‘dpkg’. Most of you may already have useded it.

Installing a program:

apt-get install

system will check the repositories and install it into the pc from a desired place. By default it will connect your PC to a FTP server and download the required package and its dependencies, then install. This method is highly effective for a good installation.

If you want to install a package which is already saved in your pc,

dpkg -i

At times you have to download the package source code/binaries and compile it then install. To do that go in to that folder and follow the following steps,

#./configure
#make
#make install

Uninstalling a program:

same tools again!

dpkg --list

using the above code you can get a list of installed programs.You can use ‘apt-get’ as shown bellow to remove programs,

apt-get remove

when after performing an ‘apt-get install’, by experience you ll understand that its installing  also other packages as dependencies. We can also remove a program with all its dependencies.

apt-get --purge

these are the basics of Linux file management via CLI. Feel free to experiment the commands and rediscover the CLI.

Airtel HSDPA [Sri Lanka]

Hi folks! Couldn’t write for about a month I think. But now I m back again with my Brand new HSDPA kit. Well HSDPA means speedy internet isn’t it? But I would have to say that life would be little more difficult and hard when you have Airtel HSDPA!

Airtel+e220

I’m using Airtel’s middle package. 600Rs per month, 3 GB free download and 1Mb/s speed. Ya its worth. But the problem is there coverage. It sucks. Not totally. But mostly! I also brought a Huawei e220 modem from Dialog GSM. It’s in good shape after unlocking. Now they both working well. But as I mentioned early I m not satisfied about Airtel HSDPA coverage and their system. Usually when some one tries to connect to a network (as other service providers do) it detects the user and gives the required setting. Like its ‘APN’ and stuff. But Airtel isn’t capable of that. I didn’t get any HSDPA settings when I tried to connect them for the 1st time. So I had to have some calls to a friend (chanux) of mine requesting to google the setting. Luckily I didn’t call their customer care, because after some time I found that its something like fallen from the sky (more..) . There APN was AirTelLive and I gave the access number as *99#. It worked! But first I got only GPRS signals. That’s because when the signal strength is low the modem software detects it and only allows the device to receive the most available signal type. If you are an Airtel data user this would be your ‘Frequently Faced Problem’.  To avoid this you can set the modem only to receive WCDMA/HSDPA signal frequencies. If you are also using an e220, go to Tools -> options -> Network and set the Network Type as WCDMA only. The handy thing is these setting are also being saved in the device. So Linux users like us don’t have to suffer thinking to find solutions to run the modem software in Linux.

So after doing some work now I’m receiving HSDPA signals. Now it only varies between WCDMA and HSDPA (no more GPRS). The signal strength is about 40% but it’s far better than having GPRS. Under 40% of signal strength I got hardly satisfied about my service provider. Also I didn’t find a way to detect my data usage over the month. It doesn’t matter if the Data package is unlimited. But there should be a way to detect it for limited users like us.  And have to say another thing! If you ever thinking to get support from Airtel’s website, then forget about it. Its totally Crap!

Hack the System [Windows XP]

Well, this is a simple method to hack into other logins. But can be useful at times.

Requirements:

è    50 seconds from your computing life

 

Procedure:

è    Simply log in to your account.

è    Open up the command prompt.

net user

è    Now type,

net user  “user name to be hacked” *

è    Then it’ll ask you to enter a password. Remember, the things you type will not be viewed. Press enter, and then retype the password to confirm.

Now the existing password of other user is replaced by the password you entered.

 

*** If your account is a ‘limited’ one this method won’t work.

Get what you wanted and run for your life………         Happy Hacking.
