GOOGLE: best friend, worst enemy.

Google.com is the most popular search engine on the  market. That’s beacuase it has the most complete and largest indexing of all internet. Here I’d like to display few interesting tricks about the google search engine.

  • Searching for the word : “hello”

https://www.google.com/#hl=en&output=search&sclient=psy-ab&q=hello&oq=hello&gs_l=hp.3..0l4.1930.2760.0.3170.5.5.0.0.0.0.80.388.5.5.0.les%3B..0.0…1c.1.5.psy-ab.cuLsoCtq5UE&pbx=1&bav=on.2,or.r_gc.r_pw.r_qf.&bvm=bv.43148975,d.dmg&fp=79c21eb3a028c18d&biw=1440&bih=735

Searching the google using the input field text box for the string “Hello” produces already a large php GET method with a lot of variables (13 different variables!)

https://www.google.com/#hl=en&output=search&sclient=psy-ab&q=hello&oq=hello&gs_l=hp.3..0l4.1930.2760.0.3170.5.5.0.0.0.0.80.388.5.5.0.les%3B..0.0…1c.1.5.psy-ab.cuLsoCtq5UE&pbx=1&bav=on.2,or.r_gc.r_pw.r_qf.&bvm=bv.43148975,d.dmg&fp=79c21eb3a028c18d&biw=1440&bih=735Let’s see what google know about me:
(& = is a separator used to separate the type variable from each other )hl=en   (language: try changing the variable to “it”, “de”, “es”)
output=search  (query type)
sclient=psy-ab  
q=hello      (query : you can type directly your search without pressing the search buttom)
oq=hello   (?)
gs_l=hp.3..0l4.1930.2760.0.3170.5.5.0.0.0.0.80.388.5.5.0.les%3B..0.0…1c.1.5.psy-ab.cuLsoCtq5UE  (looks import but i have no idea what it is)
pbx=1    (?)
bav=on.2,or.r_gc.r_pw.r_qf.  (?)
bvm=bv.43148975,d.dmg   (?)
fp=79c21eb3a028c18d   (?)
biw=1440   (?)
bih=735   (?)

As you can see google populates even the simples search (in this case “hello”) with over a dozzen of other variables which the regular user is not even aware of using. It is interesting to note that even changing 1 variable will result in a different search result list.

  • Ranking

When we search something for example the word “hello” , how does google order the search results. Why is a search result at place #1 and another one at place #200? They contain the same word, but why one is considered more relevant then the other one?

The algorithm used by google to rank pages is called PAGERANKPAGERANK takes in consideration not only how many times the queried word (or string) is repeated (like traditional pre-google search engines did), but also how many pages link to it. Linking to a page is an important factor in valuing a search result because it express the importance and relevance of that page over other results. It kinda works like a reference for a page.

  • Advanced/Customized searches

Google offers users the ability to use advanced search features to search for something. You can  add these features in your search query using the google advance search page . You Can use these features and other not described in google-advanced dirrectly in your search query with special operators and key words that google understands: here is a list (from wiki) of these features used by google that can help you specify better your query.

OR Search for either one, such as “price high OR low” searches for “price” with “high” or “low”.
“-“ Search for either one, such as “price high OR low” searches for “price” with “high” or “low”.
“+” (Removed on October 19, 2011). Force inclusion of a word, such as “Name +of +the Game” to require the words “of” & “the” to appear on a matching page.
“*” Wildcard operator to match any words between other specific words.
define: The query prefix “define:” will provide a definition[33] of the words listed after it.
stocks: After “stocks:” the query terms are treated as stock ticker symbols for lookup.
site: Restrict the results to those websites in the given domain, such as, site:www.acmeacme.com. The option “site:com” will search all domain URLs named with “.com” (no space after “site:”).
intext: Prefix to search in a webpage text, such as “intext:google search” will list pages with word “google” in the text of the page, and word “search” anywhere (no space after “intext:”).
allintitle: Only the page titles are searched(not the remaining text on each webpage).
intitle: Prefix to search in a webpage title, such as “intitle:google search” will list pages with word “google” in title, and word “search” anywhere (no space after “intitle:”).
allinurl: Only the page URL address lines are searched (not the text inside each webpage).
inurl: Prefix for each word to be found in the URL; others words are matched anywhere, such as “inurl:acme search” matches “acme” in a URL, but matches “search” anywhere (no space after “inurl:”).
  • Interestingly dangerous search results

Try to make (simple/short) queries with “filetype=log”, or “filetype=sql” (and other log/database format terminations) and than add the string search “intext=passwor” or “intext=hash”. You will find some preddy interestings search results, mostly due to system administrator mistakes in assigning the right permission/access to their file. Also some of these file (log files) are the results of different hacking tools used by other ppl, most of them phishing site, spams etc..

How to install/Fix Grub 2

This tutorial is meant to help you install fix your grub config file, and by doing so enabling you to boot into your right partitions.

Name-codes used in this tutorial:


USERNAME = your username (ex. john, abby,..)
PASSWORD = your password (ex. pAsSwRd123)
DISKNAME = your disk name (ex. sda, hdb, sdc, etc)
PARTITION = your partition name (ex. sda1, sdb2, hda3,..)
#this is a comment = do not type senteces starting with '#'. This is to explain/comment the command

 

                                         Method #1 – LIVE CD/DVD

1- Boot the computer from an USB or CD ubuntu image. At the boot screen select “Try out”UBUNTU”

screen2

2- After the desktop session has loaded start the terminal or just press CTRL+ALT+t

3- At the terminal type:


sudo su
mkdir /mnt/new
fdisk -l
#now here is the hard part; you have to figure out what is the partition you need to use in the next command, where is your "/" root-linux-system located?
mount /dev/PARTITION /mnt/new #mount the partition where you "/"(root-system) folder is located
grub-install --root-directory=/mnt/new /dev/DISKNAME #install the bootloader in the right disk

4- Now close the terminal, exit the live session, take out the cd and reboot your system.
5- Press “SHIFT” to load the new grub menu, and select “Recovery Mode”
screen

6- In recovery mode , select “UPDATE-GRUB bootloader” and select “OK”;
screen

screen2

7- Exit and reboot normally; You should see that the grub menu has changed (in case you had other OS installed in your machine)

Ubuntu – Lost Password

Let me guess… you lost your password? ehh , don’t worry the net is full of different solutions to the matter of this possible problem. First let me start by saying that this tutorial is not intended to retrive your original password (see my Cryptography section for that). Also if you have an encrypted home directory (like with TrueCrypt) this method won’t work.

There are several ways to reset your password. I will describe here 2 methods:
Method # 1 – No live cd
Method # 2 – With live cd

Name-codes used in this tutorial:


USERNAME = your username (ex. john, abby,..)
PASSWORD = your password (ex. pAsSwRd123)
PARTITION = your partition name (ex. sda1, sdb2, hda3,..)

Let’s get started!

———–Method # 1 – NO live cd————-

1- Start up the computer and at the grub menu select Recovery mode
If you do not see the grub menu press “SHIFT” key at boot time.screen2- From the recovery menu select ROOT console
screen23- At the prompt type:


root@tHOSTNAME:~#mount -o rw,remount /
root@tHOSTNAME:~#passwd USERNAME
Changing password for USERNAME.
Enter new UNIX PASSWORD:
Retype new UNIX PASSWORD:
passwd:password updated succesfully
reboot 0

———————————————–
———–Method #2 – WITH live cd————-
———————————————–

1- Boot the computer from an USB or CD ubuntu image. At the boot screen select “Try out”UBUNTU”

screen2

2- After the desktop session has loaded start the terminal or just press CTRL+ALT+t

3- At the terminal type:


sudo su
mkdir /mnt/new
fdisk -l
(now here is the hard part; you have to figure out what is the partition you need to use in the next comand, usually it's the one that hase the "*" on the line, check my screen shoot for help)
mount /dev/PARTITION /mnt/new
chroot /mnt/new
mount -o rw,remount /
passwd USERNAME
PASSWORD
PASSWORD

-screenshoot-

screen

———————–Update——————————
———————————————————–
———–Method #3 – EDIT /etc/shadow FILE ————-
———————————————————–

Let’s say you you don’t want to use the previous methods, anothe way to reset you password is to access and edit directly the shadow file of your filesystem located in /etc/shadow. I will not explain here how to mount the partition, what kind of priviledges you should have etc.. because there are multiple ways to access the linux partition, from a MacOSX, Windows, another linux distribution and so on.. but instead I will focus on how to edit the hash file properly in order to give you access to your user’s login.
here we go:
1- navigate into the /etc folder . There are sever files here, using a text editor open the one named “shadow”.
2- find the line containing your username. It should be something like this:


USERNAME:$6$XXtFftG.$K8fw0HOt5zRP5iowAqB/GSkku4MrUHYIUIUD4LCqJntS2UcU2XhMKBktVLmjGC3Kr.68PTmxO/CXOZqW7EZbPN1:15666:0:99999:7:::

what is this?
6 = hash method (SHA512)
XXtFftG. = salt
K8fw0HOt5zR....qW7EZbPN1= hashed password

3- change these line into this :


USERNAME::15666:0:99999:7:::

4- save and reboot the linux system. Login with your username and at the request to enter a password simply press enter (leave it empty).

Note this methode may not work on all distributions. I noticed that Ubuntu work only with the empty method (::) where instead other ditros may accept also (:!:) and (:NP:) inputs. They all say the same thing, which is that the user does not have a password.

Boot Info Script

How many times have you encountered booting problems? The cause of your problem may be depend on several factors: Grub conf file wrong or missing, file-system corrupted, your windows partition does not show in grub, or does not boot,  MBR corrupted, etc…   Don’t worry the net is full of program and script that can debug and find the cause or yoyur errors. I choose to include the one written by Ulrich Meierfrankenfeld  and Gert Hulselmans. It’s a clean code and very easy to use. Also you can edit it to meet your needs too.

Usage Boot Info Script:
-----------------------

Run the script as sudoer:

sudo ${0}

or if your operating system does not use sudo:

su -
${0}

When running the script, without specifying an output file, all the output
is written to the file "RESULTS.txt" in the same folder as the script.

But when run from /bin, /sbin, /usr/bin, or another system folder, the file
"RESULTS.txt" is written to the home directory of the user.

When the file "RESULTS.txt" already exists, the results will be written to
"RESULTS1.txt". If "RESULTS1.txt" exists, the results will be written to
"RESULTS2.txt", ...

To get version number, release date, last git commit and git retrieval date
of this script, use (no root rights needed):

${0} -v
${0} -V
${0} --version

To get this help text, use (no root rights needed):

${0} -h
${0} -help
${0} --help

To automatically gzip a copy of the output file, use (root rights needed):

${0} -g
${0} --gzip

To write the output to stdout instead of a file, use (root rights needed):

${0} --stdout

The last development version of Boot Info Script can be downloaded, with:
(no root rights needed)

${0} --update

If no filename is specified, the file will be saved in the home dir as
"bootinfoscript_YYYY-MM-DD_hh:mm:ss".

If multiple versions of Boot Info Script are detected in the same directory,
Boot Info Script will list all versions found.
In that case you need to force Boot Info Script to run a certain version,
by adding "--this" as first argument (root rights needed):

${0} --this

How to:
1-Copy the text to a file named: bootinfoscript.sh in your home folder
2. run the command : sudo ./bootinfoscript
3. the script will output the results in the file RESULTS.txt
3. to view simply use a text editor or run : less RESULTS.txt

How to Download Ballaro videos


Per quelli che si perdono lo spettacolo di Ballaro della rai ho qui una serie di command via termianle che possono fare utile all veduta/scarica della puntata.

Aprite il terminale e scrivete:


wget -O index "http://www.ballaro.rai.it/"
less index | grep "0;URL="
#copy l'indirizzo a destra delle lettere evidenziate
wget -O index2 "incolla_qui_il_tu_indirizzo"
less index2 | grep "/dl/RaiTV/programmi/media/ContentItem" | grep "><a href=" | head -1
#copy the url after the href tag
wget -O index3 http://www.rai.tv"incolla_qui_l'indirizzo"
less index3 | grep "videourl_"
#copy the url of the format video you want to see/ download
wget -O ballaro_video "incolla-indirizzo"
#or to stream online: mplayer "incolla-indirizzo"

Cercero di creare un shell script , cosi che si potra scaricare il video automaicamente senxa bisogno di dover copiare indirizzi. Questione di qualche giorno appena trovo un po di tempo.

LA7 download movie-ruby


This is a ruby program I found online (http://thedarkgod.wordpress.com/2011/10/22/downloading-videos-from-la7-tv/). by downloading the video you have the ability to skip comercials and fastforward the view:

here is the ruby code by Matteo:


#!/usr/bin/env ruby

require 'uri'
require 'net/http'
require 'rexml/document'

# Constants
LA7TV_URL = 'www.la7.tv'
DESCRIPTOR_URL = 'http://www.la7.tv/repliche/content/index.php?contentId=%s'
ARCHIVE_URL = 'rtmp://yalpvod.alice.cdn.interbusiness.it:1935/vod/%s'

if ARGV.empty? or not ARGV[0].include? LA7TV_URL
$stderr.puts <<-EOD
This script downloads videos from http://www.la7.it, for your personal use only.
The idea is that you can watch what you see online for free, but offline too.
Please be sensible and don't use this method for breaking the law.

Please make sure rtmpdump is installed.

Usage: #{$0}
EOD
exit -1
end

asset_number = ARGV[0].split('assetid=')[1]
xmldoc = Net::HTTP.get URI.parse(sprintf DESCRIPTOR_URL, asset_number)
xml = REXML::Document.new xmldoc
videos = REXML::XPath.match(xml, '*/videos/video')
video = videos.max_by { |video| video.elements['quality'].text.to_i }

local_filename = video.elements['originalName'].text
remote_filename = video.elements['fms'].text.gsub(/^mp4:\//, '')
remote_url = sprintf ARCHIVE_URL, remote_filename

puts "Downloading #{local_filename}\n\tfrom #{remote_url}"
Kernel.exec "rtmpdump -e -o '#{local_filename}' -r '#{remote_url}'"

How to:
1-Copy and paste the script into a text file. name it : la7.rb
2. Copy the url of the show/episode you want to see.
3. in the terminal run :
./la7.rb your_url_pasted_here
4. enjoy

Nework Diagnosis

This is a script to get a diagnosis of network’s trubleshoting ( Wi-Fi/Lan) in  your linux machine.  If you are using USB- network adapters is highly suggest that you run a lsusb command next to the scripts. Since i did not include any usb scan for network devices I suggest to use a different script or to change this one to meet your needs.

How-To:

1.download net.sh link:http://ubuntuforums.org/showthread.php?p=11194893#post11194893

2.sudo chmod +x net.sh

3.sudo ./net.sh

4. After you run the script, a file named ‘results.txt’ will be created.

content of file net.sh


#!/bin/bash
