*How to get the version of any Web server using Google?**

*Well we all love Google for its speed and capability. Now by carefully
crafting the query which you send to Google. We can get some sensitive
information which in general not shared. An example is version of the web
server software. You know how much important version information to hacker.
Now let?s find out a way to get this information without connecting to the
target server. One way is by using the information given in the directory
listings.

The query is: intitle:index.of server.at

An example query: intitle:index.of server.at site:abc.com

This will show the directory structure with the server details. The admin
can always fake this information but usually they don?t. Now you got how to
save yourself from the attack.

Some keywords which you can use in query to make them effective:

     * The site: operator* *instructs Google to restrict a search to a
       specific web site or domain. The web site to search must be
       supplied after the colon.
     * The filetype:* *operator instructs Google to search only within
       the text of a particular type of file. The file type to search
       must be supplied after the colon. Don't include a period before
       the file extension.
     * The link: operator* *instructs Google to search within hyperlinks
       for a search term.
     * The cache: operator* *displays the version of a web page as it
       appeared when Google crawled the site. The URL of the site must be
       supplied after the colon.
     * The intitle: operator instructs Google to search for a term within
       the title of a document.
     * The inurl: operator* *instructs Google to search only within the
       URL (web address) of a document. The search term must follow the
       colon.

Happy googling??..and let me know if you find this interesting?.

*Java Expert* *Playing audio in applet.*

In Applet you can play the audio by using one of two simple methods

n       public void play(URL url)

n       public void play(URL url, String name)

You know that unsigned/untrusted applet can only connect back to its
server. Hence the second method will be more useful.

Import java.applet.*;

public Class play extends Applet{

public void init(){

public void play(getDocumentBase(), ?song1.au?);

}

}

Now as soon as the applet loads it starts playing song1.au for you.

In the next issue we will see some advanced audio support.

*Linux Tips*      *Linux Birthday.*

As you all know that today is Linux?s (by Linux I mean Kernel) Birth day.
Yes Tux is 13 years old now. Thirteen years ago Linus wrote that famous
letter to the news group stating the birth of Linux. I was just thinking
about the numbe r 13. Well let's forget all SCO related issues and celebrate
its birthday. At the same time I remember a quote which goes nicely with
Linux, it goes like this "/First they ignore you, then they laugh at you,
then they fight you, then you win"./ Well you know what stage we are in.


Below is the copy of the letter which created the history. :

/From:torvalds@xxxxxxxxxxxxxxxxxx (Linus Benedict Torvalds) /

/Newsgroup: comp.os.minix /

/Subject: What would you like to see most in minix? /

/Summary: small poll for my new operating system /

/Message-ID: 1991Aug25, 20578.9541@xxxxxxxxxxxxxxxxxx /

/Date: 25 Aug 91 20:57:08 GMT /

/Organization: University of Helsinki. /

/Hello everybody out there using minix- /

/ /

/I'm doing a (free) operating system (just a hobby, won't be big/

/and professional like gnu) for 386(486) AT clones. This has/

/been brewing since april, and is starting to get ready. I'd like/

/any feedback on things people like/dislike in minix; as my OS/

/resembles it somewhat (same physical layout of the file-sytem/

/due to practical reasons)among other things. /

/ /

/I've currently ported bash (1.08) an gcc (1.40), and things seem to work. /

/This implies that i'll get something practical within a few months, and I'd/

/like to know what features most people want. Any suggestions are welcome,/

/but I won't promise I'll imp
  lement them :-) /
