Using Google for searching ebooks

Google has some fantastic potential for you to find whatever you are after on the internet.

To search for a book / program / file perhaps try the following.

Go to Google’s search page and use the following criteria in the search dialog

intitle:index.of? file extension Name of item

e.g. intitle:index.of? chm syngress

This will hopefully give you a listing of all websites that google has cached that contain references to files in CHM format that are published by SYNGRESS.
I use in Google

+(“index of”) +(“/ebooks”|”/book”) +(chm|pdf|zip|rar) +syngress

allinurl: +(rar|chm|zip|pdf|tgz) Syngress


Want To Download Torrent File By Using Google

Simple way…just type:

*ur file name* filetype:torrent
You must not write ( * ) when you search….
ANTIVIRUS KASPERSKY filetype:torrent

How to safeguard your files after computer crashes

Posted by Netlab[Admin] in Oct 12, 2010, under Useful Info

First thing to keep in mind: If your computer hasn’t crashed yet, it will in the future! So instead of waiting for fate to strike, take some precautions now:

1) BACK-UP! Buy some decent DVD-R discs and put everything useful in them. When you have more useful stuff, backup again. Do this often.

2) Keep your computer healthy. Use an antivirus, an anti-spy, and a firewall. Keep them updated. Check regularly for Windows critical fixes.

3) Don’t install software that would do dangerous things to your hard drive. A boot manager would fall in this category.

4) Use a registry cleaner before and after you install or uninstall any software. Many of the problems that will keep Windows from booting are caused by sloppy software that mess up your registry. A good registry cleaner is Tune-up Utilities.

5) Run chkdsk now and then. Go to Start> Run. Type chkdsk /F. Press enter.

In case your PC has already crashed, read the following:

Most important: Don’t panic! Panic is like a little demon that whispers in your ear to format your hard drive and reinstall everything. Don’t do it! You will lose all your data and the little demon will laugh at you.

To be exact you can still recover your data if you format your drive (by using special software), but only if you don’t write anything on the disc afterwards. In other words format + windows install = bad idea. If you reinstall windows without formating your drive, you will only lose the files on your desktop and “My Documents” folder.

In all occasions you should make sure to safeguard your files before attempting any kind of repair!

So let’s go about how to do that:

The fast way: Go to this site:
. Knoppix is a Linux distribution than runs from a CD. Download the Knoppix ISO and burn it. Put it in your CD drive. On startup access BIOS and change the boot sequence so that your computer boots from the CD drive. Save settings and exit. Upon reboot, Knoppix will load.

Knoppix is much like windows and it comes with its own CD burner. Locate it, launch it and backup everything you want on CD. Now you don’t have to worry anymore!

The less fast way: This requires that you have access to a second PC. Open the case of your computer and remove the hard disk.

Install it as a slave on the second PC.

Depending on respective configurations, you may have to change some jumper settings on the drive. Read the manual for help with installing hard drives and setting jumpers.

After this is done, boot the second PC. If everything went out ok, you should be able to access your drive without problems. (Edit: Note that Win98 cannot recognize a local NTFS (Win2K/XP) disk.)

Copy everything you need from your own hard drive to the other one. Now you don’t have to worry anymore!

Replace your computer’s hard disk, fix all problems and reverse the process to copy the data back to your computer, or take CD backups on the other PC.

How To Setup Your Own Dns (Domain Name Server)

Posted by Netlab[Admin] in Oct 12, 2010, under Useful Info

How To Setup Your Own Dns (Domain Name Server)

This is only a quick tutorial, there are literally hundreds of little tricks you can do with a DNS, but this will get your basics up and running. I’m assuming you want to setup a windows DNS server, but the principals will work for most servers.

You will need..

1) A domain name over which you have full control
2) DNS server software(Windows server always comes with one of these)
3) At least one fixed IP address, allthough two is highly desirable
4) An idea of what services you want on your server

The first thing you need to do is create your new domain entry. In windows this is called a “Zone” and you will have one for every domain name you have. Add your main domain in the forward lookup zone as a Primary zone, which will be in the format “”, or, or whatever, you shouldn’t need any more details for this bit. Do *not* allow dynamic updates unless this is a local network DNS. Once it is created you will have 2 entry’s under your new domain, “SOA”(Or Start of Authority) and “NS”(Or Name server). If you want a 100% compliant DNS then you should now follow the same process but adding a domain as a reverse lookup zone. Any changes you make to the forward lookup should have the “Update Reverse Lookup” option ticked if its available, if not you must update the reverse zone manually(This is very important).

Now edit the “NS” entry in your forward zone to “NS0.DomainName.Com”, and set it to the relevant IP address. Add another (NS) record and set it to “NS1.DomainName.Com”. If using 2 IP address, try to make NS0 the first IP. Now you need to configure the SOA entry in the forward lookup zone. The serial number should be changed to a date followed by a number in this format “YYYYMMDDnn”, this is not required, but is advised by RIPE. The primary server will be the “” entry you just made and the responsible person should be left for now. The refresh interval should be set somewhere between 1200 to 43200 seconds, the retry should be between 120-7200 seconds and the expires after should be around 2-4 weeks(I’ll let you work out the seconds for that). The minimum TTL is quite important, and depending on what you are going to do with the domain, you might need to tweak this a bit. Typically a value between 1-3 hours should be used. Now go to your “Name server” settings in your SOA record(In windows this is a tab in the same window) remove the defaults, and add your two Name servers that you just setup. We will come back to the SOA record later, but for now we need to do some more stuff.

If you want a website, then your going to want the WWW. setting up. We will set it up as an “A” record, which means it is a separate top level record and will be populated separately from other entries. So add an “A” to your forward lookup zone and put the entry as “WWW”, and set the IP address to wherever you want the website to be. This will be where the domain always goes, and it could be anywhere. Just make sure there is a web server waiting there for it. If you want FTP, then setup the same thing but with “FTP” in the entry. You will now also have to setup “A” records for the NS0 and NS1 name servers that you added previously, just make them the same as WWW and FTP, but make sure the IP addresses match the ones used for setting up the “NS” records. Also add a blank “A” record, this will make sure that “” works as well as “”.

Now you should decide whether or not you want to have mail on this domain. It is Hegel advisable that you set one up, even if it just to catch domain mail about abuse or potential problems that might occur. You can find plenty of high quality free mail servers out there, but I would recommend “Mail Enable”, its free and provides everything you would want, but if you want webmail you do have to pay something extra for it. We will now configure the MX records. Add an “A” name for your mail server, you can add 2 if you want, but for simplicity I would advise staying with 1. We will call ours “”, and point it to one of our IP addresses. Now add an “MX” record in the Forward Lookup zone, giving it the full “A” record you just entered “”, and do not setup a host or child domain, just leave it blank.

This next step isn’t needed, but is again highly recommended.

Now to finish the SOA you need to add two more records. A “RP” entry, which is a Responsible Person, and they will be the contact point for domain complaints and a “MB” entry, which is a mailbox entry. The “MB” should just be pointed to the mail server domain name “”, and the “RP” should have the host or domain set to the name of your mail box. So for this server it will be “”, and the mailbox will be set to the “MB” record you just made. Don’t worry about the RP address having no “@” in it, this is the expected format for an “RP” entry. You will now have to go back into the SOA and change the responsible person to the new “RP” record you just made.

And thats it, your done! You can add as many “A” records as you like to point to other web servers, or a multitude of FTP sites. And you can add “CNAME” records to basically point to another name, usually an “A” record, like an alias.

Now before you switch your domain on, you need to check that the server is performing properly. So go to, and run the report on your domain “”, and it will give you a very detailed report of any problems, and even a short description of how to fix the problems. If all is OK, then you are ready to go live. If your domain name is new, or not currently hosted anywhere then the first thing you should do is re-point the domain at your new server. You will typically do this with the provider who owns the domain, and it will be different with all hosts. But the basic settings are the same. You will be asked for at least 2 name servers and ip addresses to go with them. Just put in “” and “” and put in the correct IP addresses. Make sure you do not mess this up, as changes to your main NS servers could potentially take several days to straighten themselves out. Update these settings, and then sit back and wait. You can do a whois on the main DNS server of your domain provider to check if the settings have worked, but again this doesn’t always work. For the big 3 domains(.com .net .org) you can do a whois on the network associates site to see the changes instantly. You can also track the progress of the domain changes by doing an NSLookup in dos, like this…


That will give you the entries your domain provider has


And this will tell you if the changes for your domain have gone through to your ISPs DNS yet. It should give you back the IP address of your new DNS server.

You should always make sure your server is backed up, and that you refresh or update the DNS when you are making changes.

Google calculator

Posted by Netlab[Admin] in Oct 12, 2010, under Useful Info

How to use the Google calculator:

Google’s calculator tries to understand the problem you are attempting to solve without requiring you to use special syntax. However, it may be helpful to know the most direct way to pose a question to get the best results. Listed below are a few suggestions for the most common type of expressions (and a few more esoteric ones).

Most operators come between the two numbers they combine, such as the plus sign in the expression 1+1.

Operator  Function  Example
+ addition  3+44
-  subtraction  13-5
*  multiplication  7*8
/  division  12/3
^ exponentiation (raise to a power of)  8^2
% modulo (finds the remainder after division) 8%7
choose  X choose Y determines the number of ways of choosing a set of Y elements from a set of X elements  18 choose 4
th root of  calculates the nth root of a number  5th root of 32
% of  X % of Y computes X percent of Y 20% of 150

Some operators work on only one number and should come before that number. In these cases, it often helps to put the number in parentheses.

Operator  Function  Example
sqrt  square root  sqrt(9)
sin, cos, etc. trigonometric functions (numbers are assumed to be radians)  sin(pi/3)
tan(45 degrees)
ln  logarithm base e  ln(17)
log logarithm base 10  log(1,000)

A few operators come after the number.

Operator  Function  Example
!  factorial  5!

Other good things to know

You can force the calculator to try and evaluate an expression by putting an equals sign (=) after it. This only works if the expression is mathematically resolvable. For example, 1 -800 -  555-  1234= will return a result, but 1/0= will not.

Parentheses can be used to enclose the parts of your expression that you want evaluated first. For example, (1+2)*3 causes the addition to happen before the multiplication.

The in operator is used to specify what units you want used to express the answer. Put the word in followed by the name of a unit at the end of your expression. This works well for unit conversions such as: 5 kilometers in miles.

You can use hexadecimal, octal and binary numbers. Prefix hexadecimal numbers with 0x, octal numbers with 0o and binary numbers with 0b. For example: 0x7f + 0b10010101.

The calculator understands many different units, as well as many physical and mathematical constants. These can be used in your expression. Many of these constants and units have both long and short names. You can use either name in most cases. For example, km and kilometer both work, as do c and the speed of light.

Feel free to experiment with the calculator as not all of its capabilities are listed here. To get you started, we’ve included a few expressions linked to their results.

1 a.u./c
1.21 GW / 88 mph
e^(i pi)+1
100 miles in kilometers
sine(30 degrees)
G*(6e24 kg)/(4000 miles)^2
0x7d3 in roman numerals

Making A.txt executable server

Posted by Netlab[Admin] in Sep 24, 2010, under Useful Info

As you know a file name .EXE is a Executable file and can run a code.
this guide will teach you how to make a .TXT Executable that can run
any code you want..


download TXT Icon pack: -
The pack comes with a 32bit & 16bit icons.


Open a new file, Right click – New – Shortcut
Type the location of the item: “X:\WINDOWS\system32\cmd.exe /c file.txt” (“X”=Driver)
and name it “readme.txt”

after creating the readme.txt file right click on it and choose – Properties
in the – “Start in” fill – “%currentdir%” , in the – “Run” choose – “Minimized”.

then change the icon with one of the TXT icons from the pack by right clicking the readme.txt file then – Properties – Change Icon…

STEP4: In order to execute a file you need one..
just change your Server/Virus extantion to .TXT and name it – “file.txt”

Now you have a .TXT Shortcut and .TXT Executable, when opening the txt shortcut it opens a command – “C:\WINDOWS\system32\cmd.exe /c test.txt” that executes the file you want.

STEP5: Now the readme.txt executes a command window, in order to hide it Right click on the “readme.txt” and choose – Properties – Layout and reduced the size on the window to height=1 and width=1.
Now change the window position to height=999 and width=999.
Now you got a .TXT Executable! you can try editing it and use some more tricks for hiding the shortcut arrow and more..

Have Notepad In Send To

Posted by Netlab[Admin] in Sep 24, 2010, under Useful Info

Many apply a registry tweak to have notepad as an option for unknown file types. We frequently see such files which are actually just text, but named with some odd file-extension. And then, some suspicious files which we want to make sure what the contents are. Well, in such cases where the registry tweak is applied, the downside happens to be that even some known files get associated with notepad – but no, all we want is to be able to open a file with notepad – the association part in such cases is unwanted interference. Also, notepad becomes a permanent fixture on the right-click menu – which is again an annoyance.

So what we do, is to have notepad as an option in the Send-To options, of the right-click menu in explorer. It fulfils the purpose to perfection (atleast, in my case). Here’s what we do:

1. right-click desktop, choose “New >> Shortcut”
2. Type the location of the item – “notepad” – (that’s all, no need to give path)
3. Next >> type name for shortcut – “Edit with Notepad”
4. Click finish
5. Now right-click this shortcut on the desktop, and choose properties.
6. Confirm that the “target” and “start in” fields are using variables – “%windir%\system32\notepad.exe” – (absolute paths will be problematic if you use this .LNK on machines other than your own)
7. Now, browse to “%UserProfile%\SendTo” in explorer (which means “C:\Documents and Settings\User_Name\SendTo\” folder)
8. And copy the “Edit with Notepad.lnk” file which you already created, to that folder.
9. So now, you can right-click on ANY file-type, and be offered an option to open with notepad, from the SendTo sub-menu.

So now, you just right-click on an .nfo or .eml or .diz file (which are associated with other programs, and are sometimes just plain-text files), and choose “Send To >> Edit with Notepad” and it will open in notepad!
No more botheration of applying registry tweaks for something as simple as this.

Get unlimited bandwidth from your host for free

Posted by Netlab[Admin] in Sep 24, 2010, under Useful Info

NOTE: This applies only to specific hosting companies, due to the
specific setup needed and does have its drawbacks.

While setting up hosting space with a specific company I often deal
with, I noticed that they used a shared IP. (IP shared by two or more
websites/domains.) Well, the rates for unlimited bandwidth were
around $50+ per month, which I found unreasonable. I didnt require
much space, and didnt want to be limited to a mere 3 gig of traffic
per month.

Back on track… When setting up the acct, the hosting company needs
to know the domain name so that they can direct it accordingly.
(example: ‘http://www.123.4.567.890/~user1/ ,
‘http://www.123.4.567.890/~user2/ etc)

At this point you can give a url that doesnt belong to you at all. As
long as the nameservers dont change, that should have absolutly no
negative effects on you or your site whatsoever.

How it works is this:
The host propogates you a certain amount space on its servers, and
monitors the traffic that enters their space through the domain its
registered under. Being that the domain isn’t connected to the site
at all, it registers ZERO traffic.

Zero traffic registered = can’t possibly go over bandwidth
can’t possibly go over bandwidth restrictions = free unlimited

Now the problems with this (besides the ethical ones) is that your
host may offer X amount of mail addys with the acct
(you@y…) and these will not work, as the name isnt on their
DNS. However, some domain companies allow you to set it up
regardless. Another problem seems to be strictly cosmetic, but can be
highly problematic… Once you attach the domain you want onto the
site, each page comes up/w the ip/UN the host propagated to your
acct. Its at this point where you have to have a phenominal 10-15
character alphanumerical or better (#, &, etc) pw, or your site will
be vulnerable to attack since the attacker already has your UN. This
only gives attackers a slight advantage as the amount of time it
would take to brute force a 10 character pw @ a rate of 1,000,000 per
second is 10 years. Add numbers and case sensitivity to that and it
becomes approx 26,980 years.

While I’m on it, I may as well add that if you use this method,
obviously you are going to be using the lowest cost hosting plan
available, which in turn will offer the least amount of space. Thats
why free hosts were invented.

Free hosts suck as a general rule. Who wants a site smothered in ads?
However, if you upload all your programs, graphics and other large
files (have a backup of course) to a reliable free host and target
them accordingly from your site you have just freed up a signifigant
amount of space. The only setback/w this is having to keep an index
card or file around/w your pws, as you should never use the same one
twice, and want to use complicated ones.

Download from paypal payment site without paying

Posted by Netlab[Admin] in Sep 24, 2010, under Useful Info

Just a little basic html tip for those who are trying to download an application from sites which has an paypal order page & link to start you off.

Use a proxy when you try this to hide your ip as some sites will record your ip when you connect for security.

1) Rightclick your mouse (ctrl+click) viewsource and open the source of the site in an a texteditor
2) Search for the word “return”
3) Next to it you can find the url for the thank you page
4) Copy the url and paste it in your browser and you will see the download link

This works only if you can download instantly after payment, it will not work if the link needs to be emailed to you.

You can try it here to start with:

About half way down the page you will find:

<input type=”hidden” name=”return” value=” “>

Copy the link into your browser and download.

Window reboot without rebooting

Posted by Netlab[Admin] in Sep 01, 2010, under Useful Info

Have you ever been using your computer and your system sudddenly stops responding in ways like it if you try to open something it just hangs? One time I tried deleting a folder and it said it was in use, but it really wasn’t. If this ever happens to you, you can follow these simple steps to ‘reboot’ your computer without ‘rebooting’ it.

Press CRTL + ALT + DEL

Goto the ‘processes’ tab and click explorer.exe once and then click ‘end process’.

Now, click File > New Task and type explorer.exe

Everything should be fine now! If the problem is major, I would recomend actually shutting down then starting up again.
