We do start with the file preparations:

- Preparing UBCD
Unzip the ISO to an folder, lets choose C:\ubcd
Unzip the PXE Package to C:\ubcd, so that pxelinux.0, memdisk, menu.c32 and the pxelinux.cfg Folder are within the root Folder of the ubcd

- Setup up the tftpd32
Easy as hell. Download, unzip.
For example C:\tftpd32
And now to the config.

Press Ok.

Go to the DHCP Server tab and enter following Details depending on your Network configuration:

IP Pool starting adress: Should be +1 of your NIC IP if you got no other PC in your network

HOWTO: Use DBAN on UBCD to Wipe a Hard Drive

When disposing of a hard drive (or a computer containing a hard drive), the data on the hard drive should be securely deleted. Formatting or re-partitioning the hard drive will not do this properly - sensitive data can still be extracted using suitable software.

DBAN (Darik's Boot & Nuke) is a utility to securely wipe a hard drive, by repeatedly over-writing the entire hard drive several times. DBAN is included on the Ultimate Boot CD (UBCD). This HowTo will describe how to use DBAN on UBCD to securely wipe a hard drive.

To start, boot from a UBCD bootable CD. This may involve changing the BIOS options to make the computer boot from CD.

Use the menus to select Hard Disk Tools, then Wiping Tools, then Darik's Boot and Nuke. Once DBAN has booted, you will be presented with the following screen:

Autonuke

The easiest option is to type autonuke, then press ENTER. This will wipe any fitted hard drives, using the default options. The progress of each hard drive will be displayed in the main, lower part of the screen. The time taken, and an estimate of the time remaining, is displayed in the Statistics box. The screenshot below shows DBAN wiping two hard drives:

When DBAN is finished, it will display a message similar to the one below:

Interactive Mode

Interactive mode allows greater control. To start DBAN in interactive mode, just press ENTER at the DBAN start screen. When DBAN has started, you will be presented with the following screen:

Use the up/down cursor and SPACE keys to select the hard drives and partitions to be wiped. If desired, you can select the pseudo-random number generator, wiping method, verification method and rounds. Each option has explanatory text when it is selected. When you are happy with the selected options, press F10 to start wiping.

As with autonuke mode, when DBAN has finished, it will display a message. The CD can be removed and the computer powered off.

Google Started New Search Stratey

Google Instant is a new search enhancement that shows results as you type. Google pushing the limits of our technology and infrastructure to help you get better search results, faster. Key technical insight was that people type slowly, but read quickly, typically taking 300 milliseconds between keystrokes, but only 30 milliseconds (a tenth of the time!) to glance at another part of the page. This means that you can scan a results page while you type.
The most obvious change is that you get to the right content much faster than before because you don’t have to finish typing your full search term, or even press “search.” Another shift is that seeing results as you type helps you formulate a better search term by providing instant feedback. You can now adapt your search on the fly until the results match exactly what you want. In time, we may wonder how search ever worked in any other way.



Here are few benefits of Google Instant Search :

Benefits

Faster Searches: By predicting your search and showing results before you finish typing, Google Instant can save 2-5 seconds per search.
Smarter Predictions: Even when you don’t know exactly what you’re looking for, predictions help guide your search. The top prediction is shown in grey text directly in the search box, so you can stop typing as soon as you see what you need.
Instant Results: Start typing and results appear right before your eyes. Until now, you had to type a full search term, hit return, and hope for the right results. Now results appear instantly as you type, helping you see where you’re headed, every step of the way.

Configure Linux For nating eaisly

Step by Step Procedure

Step 1. Add 2 Network cards to the Linux box

Step 2. Verify the Network cards, check if they installed properly or not

Step 3. Configure eth0 for Internet with a Public (External network or Internet)

# cat ifcfg-eth0

DEVICE=eth0
BOOTPROTO=static
IPADDR=X.X.X.X
NETMASK=255.255.255.0
NETWORK=X.X.X.0
ONBOOT=yes
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
PEERDNS=yes
GATEWAY=X.X.X.X # Provided by the ISP

Step 4. Configure eth1 for LAN with a local IP (Internal private network)
# cat ifcfg-eth1

BOOTPROTO=none
PEERDNS=yes
TYPE=Ethernet
IPV6INIT=no
DEVICE=eth1
NETMASK=255.255.0.0
BROADCAST=""
IPADDR=192.168.1.1
NETWORK=192.168.0.0
USERCTL=no
ONBOOT=yes

Step 5. Gateway Configuration
# cat /etc/sysconfig/network

NETWORKING=yes
HOSTNAME=nat
GATEWAY=X.X.X.1

Step 6. DNS Configuration
# cat /etc/resolv.conf

nameserver 4.2.2.2 # DNS Server


Step 7. NAT configuration with IP Tables
First of all you have to flush and delete existing firewall rules. So flush rules by typing in terminal:

iptables -F
iptables -t nat -F
iptables -t mangle -F

Now delete these chains:

iptables -X
iptables -t nat -X
iptables -t mangle -X

# Set up IP FORWARDing and Masquerading

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
iptables -A FORWARD -i eth1 -j ACCEPT

# Enables packet forwarding by kernel (save this setting in /etc/sysctl.conf file)

echo 1 > /proc/sys/net/ipv4/ip_forward

#Apply the configuration

service iptables save
service iptables restart

# Check if iptables is set to start during boot up

chkconfig –list iptables

Step 8. Testing

Go to Client Machine
ping local LAN gateway ie local ip of linux server

Hurrey
its Done
