How to get List of All computers in my network or Computers Connected to me.

Hey All,
I am working on a project in which i have to install client software through server to all clients and the server could be a linux machine.
I just want to find the IP address and Computer names Connected to my system.

Hello DanBrown,

Welcome to the Java Programming Forums.

Take a look at this link.
It will get the IP address and computer name of the local machine. I know its not what you need but its a place to start..

I will look into how we can get the details of machines connected to the server.

this info is very useful.
I would like to share some more details regarding my project.This is an client server architecture based project in this project we can install client software from server side, so i need to show all clients connected to the server.

Hi ,

Try this code:

Code Java:

---

InetAddress localhost = InetAddress.getLocalHost();
// this code assumes IPv4 is used
byte[] ip = localhost.getAddress();
for (int i = 1; i <= 254; i++)
{
ip[3] = (byte)i;
InetAddress address = InetAddress.getByAddress(ip);
if (address.isReachable(1000))
{
// machine is turned on and can be pinged
}
else if (!address.getHostAddress().equals(address.getHostName())
{
// machine is known in a DNS lookup
}
else
{
// the host address and host name are equal, meaning the host name could not be resolved
}
}

I have expanded on Amar's code slightly. It does the job but would be nice to speed it up..

Code Java:

---

import java.io.IOException;
import java.net.InetAddress;
 
public class NetworkPing {
 
	/**
	 * JavaProgrammingForums.com
	 */
	public static void main(String[] args) throws IOException {
 
		InetAddress localhost = InetAddress.getLocalHost();
		// this code assumes IPv4 is used
		byte[] ip = localhost.getAddress();
 
		for (int i = 1; i <= 254; i++)
		{
			ip[3] = (byte)i;
			InetAddress address = InetAddress.getByAddress(ip);
		if (address.isReachable(1000))
		{
			System.out.println(address + " machine is turned on and can be pinged");
		}
		else if (!address.getHostAddress().equals(address.getHostName()))
		{
			System.out.println(address + " machine is known in a DNS lookup");
		}
		else
		{
			System.out.println(address + " the host address and host name are equal, meaning the host name could not be resolved");
		}
		}
 
	}
}
