Network Commands

Network Commands:

 

This generally means gathering information about domain by using commands like telnet, nslookup,ping, tracert, netstat etc

ping: is a part of internet control message protocol(ICMP), which is used to know whether the host is alive or not.

Example: ping hostname.com

=> ping www.facebook.com

netstat: shows protocol statistics and current tcp/ip network connections that is local, remote address, port number etc.

Example: netstat -n

telnet: is a program which runs on tcp/ip. By this we can connect to remote computer on particular port. When connected it grabs the daemon running on that port.

Example: telnet hostname.com

that is telnet hostname.com port

by default telnet connects to port 23 of remote computer.

Tracert: is used to trace the route taken by packet from source to destination.

Example: tracert hostname.com

here “*** means request timed out” indicated that fire wall installed on that system block the request and hence we can’t obtain its IP address.
