CREATING DOUBLE SSL CERTIFICATE USING TOMCAT JAVA 5

2010-09-02T18:07:00.001+05:30

Creating double SSL certificate steps:

Step 1

Create a Keystore:

Command : keytool -genkey -v -alias tomcat -keyalg RSA -validity 3650 -keystore yourcompany.keystore

This leads to a series of question where I am giving password as "changeit"(wherever required),

First and Last Name

localhost/IP Address

Organization Unit

Organization Name

Your company name

City

Bangalore

State

Karnataka

Country (two letter code)

Step 2

Creating Client cert and Keys

Command: keytool -genkey -v -alias KumarPallavCert -keyalg RSA -storetype PKCS12 -keystore KumarPallav.p12

Password: changeit

First Name or Last Name

Rest details as same as first step

Step 3

Adding Certificate Public key to keystore

Command: keytool -export -alias KumarPallavCert -keystore KumarPallav.p12 -storetype PKCS12 -rfc -file kumarpallav.cer

STEP 4

Command : keytool -import -v -file kumarpallav.cer -keystore yourcompany.keystore –alias KumarPallavCert

password =changeit

Configuring server.xml in tomcat/conf

add following lines

port ="8443" minProcessors="5" maxProcessors="75"

protocol="HTTP/1.1" SSLEnabled="true"

maxThreads="150"

enableLookups="false" disableUploadTimeout="true"

acceptCount="100" debug="0" scheme="https" secure="true"

clientAuth="true" sslProtocol="TLS"

keystoreFile="yourcompany.keystore"

keystorePass="changeit"

truststoreFile="yourcompany.keystore"

truststorePass="changeit"

NB : Put yourcompany.keystore inside tomcat root directory example ApacheTomcat6.0.14 along with directory as conf, bin etc.

How to Hide the drives(c:,d:,e:,a:...etc)
How to Hide the drives(c:,d:,e:,a:...etc)
This is a great trick you can play on your friends. To disable the display of local or networked drives when you click My Computer.

1.Go to start->run.Type regedit.Now go to:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

Now in the right pane create a new DWORD item and name it NoDrives(it is case sensitive). Now modify it's value and set it to 3FFFFFF (Hexadecimal) .Now restart your computer. So, now when you click on My Computer, no drives will be shown(all gone...). To enable display of drives in My Computer, simply delete this DWORD item that you created.Again restart your computer.You can now see all the drives again.

Beware of Image spam

2009-11-03T14:16:00.002+05:30

After a relatively long

hiatus, image spam

is making a massive

comeback in newer and

improved forms that

can evade antispam

fi lters. Rather than

clickable links, these

messages now have

obfuscated URLs hidden

as images or text, with

random white spaces

and masking characters

inserted in them.

The images even instruct users to type a URL into their

browser's address bar.

Subject lines as usual rely on deliberately

misspelled phrases promising sex enhancers and cheap

pharmaceuticals to tempt users to click on them. Multiple

similar subject lines from IP addresses spread across

many countries indicate a botnet of compromised PCs is

at work here. Globally, threats including spam have risen

dramatically in the year 2009.

Use Full Photo in Orkut rather than Cropping

2009-09-14T07:09:00.002+05:30

Recently I found orkut removing "Use Original" button while we change our dp ie profile pic after some research I found that it can be fixed using a trick of javascript.

Go to Edit Profile & Click Change Photo , then Upload your Image!
After Uploading , dont Click anything.
Use the Javascript below in the addressbar (Place where we type www.orkut.com)

javascript:with(($ = (this.orkutFrame||window).document.forms)[$.length - 1])action = "/EditSummary.aspx?apw=9999&aph=9999&apdw=9999&apdh=9999&Action.cropProfilePhoto" ,submit();void(8)

After Pasting it , Click Enter.
Some Error like "Bad, bad user! No donut for you" will come..
Never Mind that.
Now Click your home page, the uploaded Picture will be fully Sized in your Orkut Account.

Seach the contact by typing his/her name in the search box.
Step 3.
Once you got the contact click the entry to open chat window.

Right click My Computer, Properties, Advanced, Startup and Recovery, Edit. Edit BOOT.INI. Add "/SOS" right after "/fastdetect" with a space between. The line will look something like this:

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /SOS. When you're finished. The first part, multi(0)..... may not be the same on your machine. Upon restarting, the splash screen will be gone. It can be re-enabled by removing the new switch.

You may alternatively do the same with msconfig
Go To
Start-->run-->type msconfig-->BOOT.INI tab-->check SOS-->Restart

You can choose other options even if you wish and see diffrent ways of Windows XP startup.To Get back to default startup undo changes in msconfig.
Enjoy

MULTIPLE Gtalk ACCOUNTS

2008-06-16T20:39:00.000+05:30

We have been using gtalk very frequently these daz , My frnds in hostel find sometime it difficult to open there account due to lack of system in room .... So here I am presenting you the best way to open several gtalk instances from same computer ...then Keep Rocking
here it is:->

So I am posting a simple trick which will enable you multiple parallel login

to instant mesenger Google’s Gtalk or Gogle talk. You can log in to gtalk with

more than one google user account to gmail at a time. Each instance of gtalk which

will be opened after applying this trick will ask for a username password and in

each instance here you can enter different usernames & passowrds to login as

different users.

The Trick:-
create a shortcut to “C:\Program Files\Google\Google Talk\googletalk.exe” /nomutex

and save it in desktop by naming it to Multiple Login To Gtalk. Here we assume

that path to gtalk is C:\Program Files\Google\Google Talk\googletalk.exe. In your

case it may be different and you need to replace it with path to gtalk’s program

in your computer.

Edit Existing Google Talk Shortcut:-
Right click on existing google talk shortcut and open it’s properties. There open

the shortcut tab on the top. There in the textfield under the label “Target” the

path to google talk in your disk is written either append /nomutex to the end of

it or completely change it to
“C:\Program Files\Google\Google Talk\googletalk.exe” /nomutex and then click ok.

Now we modified the existing shortcut to make possible simultaneous multiple login

to gtalk by opening that short cut each time we want to log in.

Create A New Shortcut:-
Rightclick on desktop and click new->shortcut and then enter “C:\Program

Files\Google\Google Talk\googletalk.exe” /nomutex as location and Google multiple

as name of the shortcut and when ever you want multiple login, open this shortcut.

Please digg this if you like .

Here are some removal tips.
First type "msconfig" in run command(ctrl+R)

c:\>attrib -h -s autorun.inf
c:\>attrib -r autorun.inf
c:\>del autorun.inf
c:\>attrib -h -s u.bat
c:\>attrib -r u.bat
c:\>del u.bat

If you have inserted a usb thumb drive then do the above steps for it too

The amvo.exe will be in system32 i think or check in windows folder using command prompt
by typing c:\>Windows>attrib -h -s amvo.exe

Block websites without any software

2008-03-07T02:27:00.000+05:30

block webSites without any Softwares !!__________________________________________________________
Steps

1] Browse C:\WINDOWS\system32\drivers\etc
2] Find the file named "HOSTS"
3] Open it in notepad
4] Under "127.0.0.1 localhost" Add 127.0.0.2 www.orkut.com , and that site will no longer be accessable.
5] Done!

example :

127.0.0.1 localhost
127.0.0.2 www.orkut.com

- www.orkut.com is now unaccessable

For every site after that you want to add, just add "1" to the last number in the internal ip (127.0.0.2) and then the addy like before.

IE:
127.0.0.3 www.yahoo.com
127.0.0.4 www.msn.com
127.0.0.5 www.google.com

This also works with banner sites, just find the host name of the server with the banners and do the same thing with that addy.

Hope this small tutorial could keep you going in simple way of blocking websites

To Hide Disk Drives

2008-03-07T01:52:00.000+05:30

Open Registry and navigate to "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\policies\Explorer". Create a new entry by clicking on edit-> new->"Dword value". Name the value as 3fffffff.
Now each drive letter has a number. The value of the key will be the sum of the drive letter numbers. Some of the numbers are :

A:=1, B:=2,C:\4,D:=8,e:=16,f:=32,g:=64,H:=128,I:=256,j:=512,k:=1024,L:=2048 and so on. ..... Now if you want to hide "C:" and "D:" , you just have to enter value as '12'(4+8). Enter as decimal value in the dword key and restart windows.
To get back your drives just delete the key called "3fffffff".

sujin.com.np

2008-03-07T01:35:00.000+05:30

My Friend recently shared a valuable information about anew kind of VB script virus called 'sujin.com.np' virus. These days this particular virus has caused a lot of chaos in my college computer labs.
He did a extensive research on this very virus which you can easily find on his blogspot

http://www.computerethics4all.blogspot.com/

There also you will find a way to remove this virus........
But you may even try one more way which is a easier version i.e. by downloading one tool called Scanner.exe from
http://worldlink.com.np/support/download/software/Scanner.exe
(IT HAS BEEN FOUND BY GOOGLE SEARCH)

Scan your system with it , hopefully it will remove 'sujin.com.np' virus

Protecting A folder in Windows XP

2008-02-29T20:09:00.000+05:30

Its true that microsoft named all its COM objects with a unique CLSID. This ID is responsible for any behaviorial instinct in your file system. So the trick is very simple. IF we could somehow apply this trick to change the behaviour of a folder created by you with some system defined ones, our job will be over.
To do this let us create a folder named "abc" (without quotes). Now, you need to assign something to this folder so that it could be disallowed to open... Just there is a CLSID to do that.
open notepad and write

"ren abc abc.{2559a1f2-21d7-11d4-bdaf-00c04f60b9f0}" without quotes. Save the file with ".bat" extension. Let us save it as protect.bat (This is the extension of batch files) in the same location where the folder in so that it can be directly be called upon. I mean to say you need to create the batch file in the parent directory of abc. Double click on the file and your folder will be locked.

To unprotect it just change the line to this:
"ren abc.{2559a1f2-21d7-11d4-bdaf-00c04f60b9f0} abc"

Changing the Boot Screen of Windows XP

2008-02-29T20:03:00.000+05:30

Well, To change the boot screen, you first need to download appropriate boot screen from the personal website. There are lots of bootscreen in different websites like themexp.org. First download those files from there. The names of all the files will be like ntskrnl.exe. Just backup the original file from your windows/system32 directory. And just paste it there. Or you can rename the new file just downloaded to another name, say abc.exe. and paste it to the windows/system32 directory. If the file name is changed, you need to add an entry to the boot.ini file. Just open my computer and type c:\boot.ini in the address bar. you will be given with a text editor. just in the last line paste like the following..

multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /NoExecute=OptIn /KERNEL=abc.exe

Create a undeletable Folder in XP

2008-02-29T19:59:00.000+05:30

Well, Try to create a folder in windows platform with the name CON, AUX, COM1, COM2, COM3, COM4, LPT1, LPT2, LPT3, PRN, NUL....

You cant able to do it...
Its just because of some system calls of this services already been there for those names. So If you try to create or delete those system calls, It will restrict you in doing them... But I have a solution to this..
Try the following steps.. :

STEP1: goto command prompt

STEP2: type in prompt c:\> "md \\.\c:\con"

STEP3: verify by typing "dir \\.\c:\con"

STEP4: delete the file or folder "rd \\.\c:\con"
Now you can see a folder named con in your c drive... Give replies...
