JavaScript - I Need To Decipher This Exploit Code That Was Dumped On Our Server

I need help to make a Server to server connection

I already have a server connected to clients, clients send msgs and it echoes back to all of them and now i want when a client sends a msg it echoes on his server and the other server too .. so when any of the clients on any of the servers sends a msg it is broadcasted all over the servers to all clients

This is my SERVER code

Code:

import java.io.*;
import java.net.*;

public class MultiThreadChatServer {

	// Declaration section: This part to declare the server socket, client
	// socket, input stream
	// and output stream

	static Socket clientSocket = null;
	static ServerSocket serverSocket = null;

	// server can hold up to 10 clients

	static clientThread t[] = new clientThread[10];

	public static void main(String args[]) {

		int port_number = 6000;

		if (args.length < 1) {
			System.out.println("Server Started \n" + "Now using port number="
					+ port_number);
		} else {
			port_number = Integer.valueOf(args[0]).intValue();
		}

		// Initialization section: Where I try to open a server socket on the
		// given port

		try {
			serverSocket = new ServerSocket(port_number);
		} catch (IOException e) {
			System.out.println(e);
		}

		// Create a socket object from the ServerSocket to listen and accept
		// connections
		// Open input and output streams for this socket will be created in
		// client's thread since every client is served by the server in
		// an individual thread

		while (true) {
			try {
				clientSocket = serverSocket.accept();
				for (int i = 0; i <= 9; i++) {
					if (t[i] == null) {
						(t[i] = new clientThread(clientSocket, t)).start();
						break;
					}
				}
			} catch (IOException e) {
				System.out.println(e);
			}
		}
	}
}

// This client thread opens the input and the output streams for a particular
// client,
// ask the client's name, informs all the clients currently connected to the
// server about the fact that a new client has joined the chat room,
// and as long as it receive data, echos that data back to all other clients.
// When the client leaves the chat room this thread informs also all the
// clients about that and terminates.

class clientThread extends Thread {

	DataInputStream is = null;
	PrintStream os = null;
	Socket clientSocket = null;
	clientThread t[];

	public clientThread(Socket clientSocket, clientThread[] t) {
		this.clientSocket = clientSocket;
		this.t = t;
	}

	public void run() {
		String line;
		String name;
		try {
			is = new DataInputStream(clientSocket.getInputStream());
			os = new PrintStream(clientSocket.getOutputStream());
			os.println("Enter your name.");
			name = is.readLine();
			os.println("Hello " + name
					+ " you can now start chatting with all the connected chat-mates");
			for (int i = 0; i <= 9; i++)
				if (t[i] != null && t[i] != this)
					t[i].os.println(".." + name + " has entered the chat room ..");
			while (true) {
				line = is.readLine();
				if (line.startsWith("/quit"))
					break;
				for (int i = 0; i <= 9; i++)
					if (t[i] != null)
						t[i].os.println("<" + name + "> " + line);
			}
			for (int i = 0; i <= 9; i++)
				if (t[i] != null && t[i] != this)
					t[i].os.println("" + name + " has left the chat room ..");

			os.println("Bye " + name + " ..");

			// Clean up:
			// Set to null the current thread variable such that other client
			// could
			// be accepted by the server

			for (int i = 0; i <= 9; i++)
				if (t[i] == this)
					t[i] = null;

			// close the output stream
			// close the input stream
			// close the socket

			is.close();
			os.close();
			clientSocket.close();
		} catch (IOException e) {
		}
		;
	}
}

This post will contain a few guidelines for what you can do to get better help from us. Let's start with the obvious ones:

- Use regular language. A spelling mistake or two isn't anything I'd complain about, but 1337-speak, all-lower-case-with-no-punctuation or huge amounts of run-in text in a single paragraph doesn't make it easier for us to help you.

- Be verbose. We can't look in our crystal bowl and see the problem you have, so describe it in as much detail as possible.

- Cut-and-paste the problem code. Don't retype it into the post, do a cut-and-paste of the actual production code. It's hard to debug code if we can't see it, and this way you make sure any spelling errors or such are caught and no new ones are introduced.

- Post code within code tags, like this [code]your code here[/code]. This will display like so: Code:

alert("This is some JavaScript code!")

- Please, post the relevant code. If the code is large and complex, give us a link so we can see it in action, and just post snippets of it on the boards.

- If the code is on an intranet or otherwise is not openly accessible, put it somewhere where we can access it.

- Tell us any error messages from the JavaScript console in Firefox or Opera. (If you haven't tested it in those browsers, please do!)

- If the code has both HTML/XML and JavaScript components, please show us both and not just part of it.

- If the code has frames, iframes, objects, embeds, popups, XMLHttpRequest or similar components, tell us if you are trying it locally or from a server, and if the code is on the same or different servers.

- We don't want to see the server side code in the form of PHP, PERL, ASP, JSP, ColdFusion or any other server side format. Show us the same code you send the browser. That is, show us the generated code, after the server has done it's thing. Generally, this is the code you see on a view-source in the browser, and specifically NOT the .php or .asp (or whatever) source code.

At the moment I have an exchange server which enables shared calendars.

I would like to use Javascript to write to a shared calendar i.e. add a event.

Can this be done?

Hi,
I am hosting my website in free server (freehostia.com) and i am using joomla1.5 . I want to parse RSS from my other websites. Joomla does it with its modules. But the server do not allow outbound HTTP request, hence i had use rss-to-javascript website to parse RSS feeds. It parses well but there is its advertisement below the feed (which i think is nonsense).

The link it provides is in the format of
<script src="http://somethin.com/somdfile.php?parse=.."></script>

when i put the link in my browser i see following
document.write("string of my parsed xml file with advertisement at end");

What i want to do is get the sting of above line and edit it to chop off the end advertisement.

if there was any method to load that output sting in any variable, the task would had been completed.

If anybody knows how to do it, please help me.

I have a google blogger site on which I want to run a PHP script. The problem is that blogger doesn't have a PHP interpreter.

So I was thinking, can I run the php file on a remote server that supports php, and load the result in a div in blogger?

Thx!

Hi,

I am trying to access an XML file from a server in my JavaScript code.
I have an XML file like this:

-<stream version="1.2">
-<room id="simulator" time="128168557915">
-<dimention id=0 x="1.25" y="2.00">
<m mcu="160" sid="75">
</dimention>
</room>
-<room id="simulator" time="128168557928">
-<dimention id=0 x="1.95" y="1.86">
<m mcu="160" sid="55">
</dimention>
</room>
</stream>
this file is generated by an application and I can access it from a URL ( since I am using the simulator for this application the XML is accessible from http://localhost:8081/feed/demo)
This xml file is updated every few seconds and constantly growing.
I have a javascript code which I've added the following code to it in order to use the data from XML file:

<script type="text/javascript">
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.open("GET","http://localhost:8081/feed/demo",false);
xmlhttp.send();
xmlDoc=xmlhttp.responseXML;
document.write("<table border='1'>");
var x=xmlDoc.getElementsByTagName("room");
for (i=0;i<x.length;i++)
{
document.write("<tr><td>");
document.write(xmlDoc.getElementsByTagName("dimention")[i].getAttribute("x"));
document.write("</td><td>");
}
document.write("</table>");

</script>

Now here comes my problem: if I have the XML file saved on same drive as html page and I address it like this:
xmlhttp.open("GET","floor.xml",false);
it works fine, but when I pass the URL it doesn't. is there anything else I should do in case of loading the xml from URL?

my second question is that I want to use the text values returned by xmlDoc.getElementsByTagName("dimention")[i].getAttribute("x") in an if statement like this :
if (valuereturned = 2.00)
{
do sth
}
what is the best way to do that, since the returned value is a text.

I need the answer ASAP and I really appreciate your help, thanx :-)

I recently coded a page that extracts certain nodes from an external XML file and prints a line of text on the webpage.

It is an HTML page that is strictly devoted to this purpose. There is no other information on it.

The page is currently stored locally on my computer, and when I open it, the script runs fine and outputs the correct text.

However, when I transferred this script over to my web server, and locate it that way, it doesn't run correctly. When I go to the page, it is supposed to display a line of text at the top. It does when I run the file from my local machine, however when I open it from the server, it doesn't display this text. (Same browser, same computer)

When I right-click and view the source, all the code is there, and the files are identical.

Any idea as to why the script runs correctly only when I open the HTML page locally?


I appreciate any help or advice.

Thanks!

Ok my lab6 at

Hi Chaps,
I have JavaScript code, that exports a HTML table to MS Excel.
This works fine on my development (local) server, however, it fails to work on my 'live' IIS server. Once I click on the Export link, I confirm the "Export to Microsoft Excel?" message, then nothing happens. I am not sure if MS Excel needs to be installed on the server or not?
If anyone has any ideas, I'd be most grateful:
Code:

<script language="javascript" type="text/javascript">  
function ExportToExcel() {
	input_box=confirm("Export to Microsoft Excel?");
		if (input_box==true) {
			
			var xlApp = new ActiveXObject("Excel.Application");
			// Silent-mode:
			xlApp.Visible = true;
			xlApp.DisplayAlerts = false;
			var xlBook = xlApp.Workbooks.Add();
			xlBook.worksheets("Sheet1").activate;
			var XlSheet = xlBook.activeSheet;
			XlSheet.Name="Report";
			
			// Store the sheet header names in an array
			var rows = tblrepeat.getElementsByTagName("tr");
			var columns = tblrepeat.getElementsByTagName("th");
			var data = tblrepeat.getElementsByTagName("td");
			
  			// Set Excel Column Headers and formatting from array
			for(i=0;i<columns.length;i++){
				XlSheet.cells(2).value= "Projects - All";
	   			XlSheet.cells(3,i+1).value= columns[i].innerText; //XlSheetHeader[i];
	   			XlSheet.cells(3,i+1).font.color="6";
	   			XlSheet.cells(3,i+1).font.bold="true";
	   			XlSheet.cells(3,i+1).interior.colorindex="37";
				XlSheet.Range("A1:B1000").HorizontalAlignment = -4131;
			}
			
			//run over the dynamic result table and pull out the values and insert into corresponding Excel cells
			var d = 0;
			for (r=4;r<rows.length+3;r++) { // start at row 2 as we've added in headers - so also add in another row!
				for (c=1;c<columns.length+1;c++) {
					XlSheet.cells(r,c).value = data[d].innerText;
					d = d + 1;
				}
			}
			
			//autofit the columns
			XlSheet.columns.autofit;
			
			// Make visible:
			xlApp.visible = true;
			xlApp.DisplayAlerts = true;
			CollectGarbage();
			//xlApp.Quit();

if the proxy is an intermediary between the client and the requested url
could that url be sent to two different clients in response?
so in stead of this

[client]<-->[proxy]<-->[website]

it would be this

[client1]<-->[proxy]<-->[website]
.................. /
...........[client2]

meaning if [client1] requests "google.com" on the proxy server
the proxy server will request "google.com" and send it back to [client1]
as well as [client2]

it would just be url sharing between two people, like a real time delicious.com

heya, ^.^ sorry if this is in the wrong section, im new here so i wasn't sure as it concerns both java and php, so basically i've made a website that pings a server address when someone views the site, but currently it will ping every time you f5 or refresh ect, what i need it to do is only ping once every 2mins, store the value for when its not being pinged to be displayed, now i got told this could be done in javascript?, but my knowledge of javascript is very minimal,

i also got told that
"var m_pingDomain_timer = setInterval(dopingDomain, 120);"

may have something to do with it?, and help /code or pointers in the right direction would be a great help ,

il leave you with the PHP code so you can look over below

Code:

        <tr>
          <td class="SEBody1">
			<?php
			// Function to check response time
				error_reporting(0);
				function pingDomain($domain)
				{
					$starttime = microtime(true);
					$file      = fsockopen ($domain, 80, $errno, $errstr, 10);
					$stoptime  = microtime(true);
					$status    = 0;

					if (!$file) $status = -1;  // Site is down
					else {
						fclose($file);
						$status = ($stoptime - $starttime) * 1000;
						$status = floor($status);
						}
					return $status;
				}
				
				echo '<table>';
					$domainbase ="google.com";
					$status = pingDomain($domainbase);
					if ($status != -1) echo "<img src='img/shard_status_online.png' width='18' height='18' alt='Online' />Online";
					else  echo "<img src='img/shard_status_offline.png' width='18' height='18' alt='Offline' />Offline";
		
				echo '</table>';
		 ?>	
		  </td>
          <td class="SEBody1">로그인</td>
          <td class="SEBody1">Login</td>
          <td class="SEBody1">
			<?php 
				if ($status !=-1) echo "$status ms";
				else echo "0 ms";
			?>
	</td>
        </tr>

I'm trying to get my Client Side Firefox DHTML app to display a list of eBooks. For this, i have the following files

F:\Textbooks.html
F:\eBooks.txt
F:\FirstBook.txt
F:\SecondBook.txt
F:\ThirdBook.txt


textbooks.html is my DHTML app
eBooks.txt is the Library file with a listing of all of my eBooks.
Inside of eBooks.txt is the following data:
-----------------
FirstBook.txt,
SecondBook.txt,
ThirdBook.txt,
-----------------

FirstBook.txt to ThirdBook.txt are my actual ebooks.


The problem that i'm having is that When i try to click on any buttons other than the FirstBook button, i get the following error:

----------------------------------
Error: unterminated string literal
Source File: file:///F:/Textbooks.html
Line: 1, Column: 10
Source Code:
LoadEbook('
----------------------------------

So, unlike clicking on the FirstBook button, these other buttons do not load the eBook data into the DIV for displaying the eBook data.

I use the DOM insepector to checkout the DOM of the button code, and it seems like whitespace maybe is the problem. However, i have removed whitespace from the HTMLdata string, and that's not fixing the problem.

did i forget something silly? LOL

i'm using FireFox 3.5 to develop this App. So obviously this will not work with anything other than Gecko Based browsers.

here is my HTML code:

document.getElementById("EbookToolbar").style.visibility = "visible";
document.getElementById("FileManager").style.visibility = "visible";



// Load the List of eBooks in the Library
LoadBookList();
}

function UpdateEbookList()
{
// Update the Library of Ebooks
alert("Updating eBook Library");

// Go back to the File Manager, and Reload the List of Ebooks
LoadBookList();
}

function LoadBookList()
{
// This will load the list of books that are available
var EbookList = LoadFromDisk(SystemPath + eBookLibrary);
var EbookListArray = EbookList.split(",");

for(var x = 0; x < EbookListArray.length -1; x++)
{
// Strip the Filename Extension off of the eBook File Name
// The Name of the Book is always the first Index in the Array
var BookName = EbookListArray[x].split(".");
// Remove the weird whitespace - it screws things up...i think...
BookName[0] = BookName[0].replace(/(^\s*|\s*$)/g, "");

var HTMLdata = HTMLdata + "<input type='button' value='" + "FirstBook" + "'" + " onClick=LoadEbook('" + EbookListArray[x] + "');><br>";
}

// For some ****ed up reason the first string always generates an 'undefined' even though it's nonsense
// So just delete that from the HTMLdata string, because it's just ugly - LOL
HTMLdata = HTMLdata.replace("undefined", "");
HTMLdata = HTMLdata.replace("", " ");

// Write the HTML data to the DIV
document.getElementById("FileManager").innerHTML = HTMLdata;
}

Hello there,

I am using Dynamic Drive's dhtml windowfile and when I had a link for it to call the popup window, it makes my site deliver a 500 server error. Here is the line of code I'm adding:

Code:

echo '<td><a class="link" href="#" onClick="ajaxwin=dhtmlwindow.open('ajaxbox', 'ajax', 'pages/post.php', 'Composing Mode: Post', 'width=650px,height=400px,left=300px,top=100px,resize=0,scrolling=1'); return false">Compose</a></td>';

It is not a php issue, I plaintext the link and it still did the same thing.

I am wanting to setup a dependant drop down where when a user clicks on the first drop down, it changes the contents of the second. The way I intend to do this is via a csv file. I have found several scripts but I have been unable to get them to work.

Two of which a

http://purbayubudi.wordpress.com/200...ng-javascript/

The first is the better option from what I can see. but the problem is readyState seems to be always 1.

I am wondering if someone could perhaps give me a few moments to see if I can get this to work or suggest a better solution.

I don't want to use a database approach, at least not yet.

Dear friend ,

I am uploading text file on html page ,
that text file lies on desktop and getting updated at every hour . I will keep my html page on server so how will it upload that text file from my desktop ? it is being generated by one cloud sensor .
