Network Hacking

Network Hacking is generally means gathering information about domain by using tools like Telnet, NslookUp, Ping, Tracert, Netstat, etc.

It also includes OS Fingerprinting, Port Scaning and Port Surfing

using various tools

Ping :- Ping is part of ICMP (Internet Control Message Protocol) which is used to troubleshoot TCP/IP networks. So, Ping is basically a command that allows you to check
whether the host is alive or not.

To ping a particular host the syntax is (at command prompt)-- 
c:/>ping hostname.com
example:- c:/>ping www.google.com

Various attributes used with 'Ping' command and their usage can be viewed by just typing c:/>ping at the command prompt.

Netstat :-  It displays protocol statistics and current TCP/IP network connections. i.e. local address, remote address, port number, etc. It's syntax is (at command prompt)
c:/>netstat -n

Telnet :- Telnet is a program which runs on TCP/IP. Using it we can connect to the remote computer on particular port. When connected it grabs the daemon running on that port.

The basic syntax of Telnet is (at command prompt)--

      c:/>telnet hostname.com

 By default telnet connects to port 23 of remote computer. So, the complete syntax is-
c:/>telnet www.hostname.com port

example:- c:/>telnet www.yahoo.com 21
                            or
 c:/>telnet 192.168.0.5 21

Tracert :- It is used to trace out the route taken by the certain information i.e. data packets from source to destination.

It's syntax is (at command prompt)--

      c:/>tracert www.hostname.com

example:- c:/>tracert www.ebay.in
