Get Buffer size on FTP Server

You can find out the current internal buffer size for your data socket by using the FTPClient class method.

int getBufferSize() : This method returns int value. It fetches the present internal buffer size for your data sockets.

Example :

Here is an example to print the internal buffer size for our data socket.For that we are calling method client.getBufferSize().

File : FtpGetBufferSize.java
 

package com.simplecode.net;

import java.io.IOException;

import org.apache.commons.net.ftp.FTPClient;
import org.apache.commons.net.ftp.FTPConnectionClosedException;

class FtpGetBufferSize {
	public static void main(String[] args) throws IOException {
		FTPClient client = new FTPClient();
		boolean result;
		try {
			// Connect to the localhost
			client.connect("localhost");

			// login to ftp server
			result = client.login("admin", "admin");

			if (result == true) {
				System.out.println("User logged in successfully !");
			} else {
				System.out.println("Login failed!");
				return;
			}

			// Get buffer size
			System.out.println("Current Buffer size : "
					+ client.getBufferSize());

		} catch (FTPConnectionClosedException e) {
			System.err.println(e);
		} finally {
			try {
				client.disconnect();
			} catch (FTPConnectionClosedException e) {
				System.err.println(e);
			}
		}
	}
