Network Hacking Trick

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)--


example:- c:/>ping

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)--

By default telnet connects to port 23 of remote computer.
So, the complete syntax is-

c:/>telnet port

example:- c:/>telnet 21 or c:/>telnet 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)--

example:- c:/>tracert

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 operator
