Ping: Ping is generally used to determine whether the remote host is up or not.
Type ping <hostname> or IP address
If no packets are lost in sending or receiving then the remote host is definitely up.
eg. ping www.google.com
The default packet size sent & recieved is 32 bytes.
Now lets modify it a little.
Ping -l 64 www.google.com
where 64 is the size of the packet
ping -t www.google.com
This will ping the specified host until stopped. I mean this will keep pinging the host until stopped by Ctrl+C.
Netstat- Netstat displays protocol statistics and the current TCP/IP network connections.
Netstat is a good in built tool that comes with the windows.
-a option displays all connections and listening ports.This will display for TCP as well as the UDP connections.
-b This is the best option. This displays .exe involved with TCP/UDP connection.
This -b option may be used to detect a trojan horse or a malware.
There are other filtering options available too.
Ipconfig – This displays the current IP of the system and its configuration and current network settings
type ipconfig & press enter.
ipconfig/all displays a detailed information.
So these are some of the useful network tools that come shipped in with Windows.
