heres the code,its almost the same with the code of surfer tim,i just change the ip,username and password.

#include <SD.h>
#include <SPI.h>
#include <Ethernet.h>
// comment out next line to write to SD from FTP server
#define FTPWRITE
//ÿ

// this must be unique
byte mac[] = { 0x90, 0xA2, 0xDA, 0x00, 0x59, 0x67 };

// change to your network settings
IPAddress ip( 192, 168, 88, 2 );
IPAddress gateway( 192, 168, 88, 1 );
IPAddress subnet( 255, 255, 255, 0 );

// change to your server
IPAddress server(192, 168, 88, 1);

EthernetClient client;
EthernetClient dclient;

char outBuf[128];
char outCount;

// change fileName to your file (8.3 format!)
char fileName[13] = "test.txt";
File fh;

void setup()
{

digitalWrite(10,HIGH);

if(SD.begin(4) == 0)
{

}

digitalWrite(10,HIGH);
delay(2000);
Serial.println(F("Ready. Press f or r"));
}
