Network Hacking

Section 1 – 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 mediacollege.com

SECTION 2-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 -nr

 SECTION-3 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 

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

c:/>telnet 192.168.0.5

Section 4 – 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.google.com 

Here "* * * Request timed out." indicates that firewall installed on that system block the request and hence we can't obtain it's IP address. various attributes used with tracert command and their usage can be 

viewed by just typing c:/>tracert at the command prompt. The information obtained by using tracert command can be further used to find out exact operating system running on target system.
