Socket connection - Available Port Numbers

Hi,
I am trying to connect to a server running on Unix through my NT client. This is being done via socket connection and by supplying IP Address of the machine plus the port number.
My server is running on Unix, Solaris 8, Ultra 5 machine. I want to know if there is some allowable range of Port Numbers on the Unix machine?
Or is it that I can use any number starting from 1 to infinite as my port number?
Thanks.

The ports below 1024 are reserver for only the "root" user and 65536 is usually the max port
number available. Ports below 1024 are also reserved for a user in the Administrators group on NT and W2K.
Actually, the maximum port number is 65535 since IPv4 port numbers are 16 bit quantities and that is the maximum value of a 16 bit quantity.

Cannot open socket connection on port 443

Hi!
Our server is running on Port 443.
When I try to Connect from the BlackBerry 9300, an exception is thrown "cannot open socket connection on port 443"
Can any one please help me in finding the solution to enable the port 443.
Thank you in advance!

Can a socket connection be created inside a Timeline to port 23?

Is there a security restriction or some other reason why I always get a java.net.ConnectException: Connection refused at java.net.PlainSocketImpl.socketConnect(Native Method)
when I try to open a socket inside a function in a Timeline to port 23? The connection works fine to the host if the code is not is not inside a Timeline. It also seems that a socket connection to port 80 works okay too.
Thanks for any help in advance.
Regards,
Richard

Here is the Timeline code:
var addr:InetSocketAddress;
var sConn:Socket;
var reader:BufferedReader;
var s:String;
Timeline {
repeatCount: Timeline.INDEFINITE
keyFrames: [
KeyFrame {
time: 10s
action: function() {
try {
addr = new InetSocketAddress("somehost",23);
sConn = new Socket();
sConn.connect(addr);
reader = new BufferedReader(
new InputStreamReader(sConn.getInputStream()));
// reader.readLine(); // throw away first line
s = reader.readLine();
bindTemp = response.getResponse("$0001").getTemperature();
bindVolt = response.getResponse("$0001").getVoltage();
} catch (e:Exception) {
System.err.println(e);
}.play();
The ConnectionRefused error occurs only when the NetBeans Project Application Properties "Draggable Applet" checkbox is checked ( which is the default ). Once I uncheck it, the error goes away.

Socket connection

Hi,
I want to connect swf file running in www.xxx.com via socket
to www.xxx.com:25
My crossdomain.xml looks like:
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "
http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="www.xxx.com/*" to-ports="25"
/>
</cross-domain-policy>
But when i do remote debug i see this error:
Se ha detenido la conexión con www.vescovoweb.com:25 -

Anyone can help me?

It's the socket constructor:
public function SendMail(host:String = null, port:uint = 0)
try
Security.loadPolicyFile("
http://" + host + "/crossdomain.xml");
} catch (error:Error){
trace('NO crossdomain.xml\n'+error.message+'\n');
socket = new Socket();
configureListeners(socket);
try {
trace("Trying to connect to " + host + ":" + port + "\n");
socket.connect(host, port);
} catch (error:Error) {
trace(error.message + "\n");
socket.close();
In the third row i load the policy file but i suppose the
loading is fine because flash don't tell me any error when it's
load.
Any suggestion?

Multiple socket connection in TC65

Hello!
I connect TC65 with server by socket connection on port 23. I close this socket, output and input streams as well. Because I've read some information from server I want to connect to another device using socket connection on port 43 for example, but it seems it doesn't work. I guess in some way it could be done because I closed previous connection. Any advise?

Right, I'm getting tired of this already.
NO, I'm not going to send you any code, you lazy nitwit. Neither will anybody here.
Your use of the imperative form in your question is rude. You may talk like that to your colleagues, but in a forum where people answer questions in their spare time and on a voluntary basis this is inacceptable.
You didn't even bother to say "please", at the least. Not that this would have changed much, but at least you wouldn't have been barking.
[url http://www.catb.org/~esr/faqs/smart-questions.html]This document might provide you some orientation.
As for your problem, first find out what exactly it is you want to do. Search the web, as kajbj counselled, it's quite a common task. If you have a specific problem, ask. But, take my advice and never, never ever ask people to "send you code" in a forum.

Open a Socket Connection

I have an RFID reader that has an internal memory bank that
stores rfid scans. From speaking to the company in order to get the

Problem with socket programming-connecting to port 13

Hi, I am learning JAVA, and we are on the subject of sockets. I am trying to make this program to connect to port 13, get the time, and print it to the console. This is my code:
import java.io.*;
import java.net.*;
public class temp {
 public static final int PORT = 13;
 public static void main(String[] args) {
 Socket s = null;
 String line = null;
 try {
 s = new Socket("localhost", PORT);
 DataInputStream sin = new DataInputStream(s.getInputStream());
 line = sin.readLine();
 if (line != null) System.out.println(line);
 catch (IOException e) {System.err.println("!" + e);}
 finally {
 try { if (s != null) s.close(); }
 catch (IOException e2) {}
And this is the output:
!java.net.ConnectException: Connection refused: connect
What should I do. I found that the problem is with the server I am connecting to and I tried connecting to dif. computers, or to stuff online, and nothing works.
Any suggestions for me?
Forgot: I tried this on both a windows XP and Vista
Edited by: xpatrickerx on Mar 23, 2008 8:12 PM
Tampering with it, I find that the error occurs on the following line:
s = new Socket("localhost", PORT);
Edited by: xpatrickerx on Mar 23, 2008 8:13 PM

So I finally found how to use printStackTrace and here is what it gives when:
1) I use my own computer:
java.net.ConnectException: Connection refused: connect

Connect Flash to Serial Port with Local Socket Connection

Hey all,
So, I am trying to connect a Flash movie to a serial port
and have it react to the input coming in. Of course, Flash does not
have this capability built in, so I need a workaround. I also
program in Director, and there are easier ways to deal with this
there, but since there hasn't been an update in years, and for
other technical reasons, I would like to use a pure Flash program.
I also need to take advantage of some of the new hardware
acceleration improvements and horizontal sync issues that come with
running the Flash player full screen. So, there are some tools out
there that will let me stream the input from the serial port to a
web address. I figure I could use the local address and assign a
port number, then use Flash to create a local socket connection. I
am having issues opening ports on my computer, and a few other
things, but in theory, I think it should work. I know that I won't
get all the answers here, but if anyone has done anything of the
sort, or might know of some similar projects, it would really help.
I am more of a Director/Flash programmer, and not so much one on
the system level. So, opening local sockets, etc, while I am sure I
can figure it out, is still a bit beyond me. Thanks all!
- Bruce

You may want to look into flash remoting, which would allow
you to push content to the flash movie. You could then write a
proxy between the source of your stream and flash the remoting
server.

Problem: Socket connection is not creating in machine, through utility program (MFC Dll), on ListDisplay service port - 3334 (on separate machine), while we are able to telnet on same ListDisplay service port - 3334 from same issue machine on same time

Problem: Socket
connection is not creating in machine, through utility program (MFC Dll), on ListDisplay service port - 3334 (on separate machine), while we are able to telnet on same ListDisplay service port - 3334 from same issue machine on same time
Environment: -
OS:
Windows XP SP2/7
Code:
VC 6.0
Dll: MFC
Problem Description: -
We have written a utility program which create socket (Using windows standard method [MFC]), and then make connection with another service (List Display) running
on port 3334 in different machine and retrieve the required list data. This program was working fine in almost all the machines.
But, we have received a severe intermittent issue on two machines. Client is facing issue in displaying the list data from port 3334.
Attempt: -
First we tried to debug code, and we come to know that socket is not creating in utility program. So we tried to telnet on ListDisplay service port 3334 and we were surprised that we were able to telnet, then we opened some more
telnet window on same port 3334 around (6 to 8) window, and each cmd connected properly. But we were not able to create socket from utility program.
Problem is severe because issue is intermittent.
We have tried all the way, but we are not able to figure it out, that what can be the exact problem and what are the conditions, when utility program will not
connect with ListDisplay service on port 3334.
Kindly assist to resolve this issue. For any help, we would be really thankful.

Hi,
According to your description, it seems that you have created an utility program which is making connection with another service port 3334, however, two clients are facing issue in display the data list from port 3334.
Port: 3334/TCP
3334/TCP - Known port assignments (1 record found)
Service
Details
Source
directv-web
Direct TV Webcasting
IANA
Since the port 3334 is used by directv-web service, I'd like to suggest check this service it is working well on the problematic clients.
1. The client can be resolved in DNS well? Please run "nslookup" in the prompt command.
2. Is there any 3rd party application interrupting? Do test in clean boot.
2. Strongly suggest you run process monitor tool to analysis it.
I am looking forward to your reply if you have any updated on your side.

Different port numbers available in xi

Hi
while I was going through the forum I have come across different port numbers like j2ee port, http port, smpt etc. Could you please summarize what are all the different ports that xi has to communicate and how to find that prot numbers. I mean different transactions to see the same.

Hi,
The following instances will be created as per the type of installation.
Abap+java system =
/usr/sap/<SID>/DVEBMGS<NR>
/usr/sap/<SID>/SCS<NR1>
Stand alone java system =
/usr/sap/<SID>/JC<NR>
/usr/sap/<SID>/SCS<NR1>
All the port numbers are determined by the NR and not by NR1.
You will have JC<NR> when you have a standalone Java system installed and DVEBMGS<NR> when you have a ABAP+JAVA system installed. Both of these will not exist together for a particular Installation.
And you will have SCS instance in both the cases i.e if you have Java Addin( ABAP+JAVA) or a Standalone Java System.
Thanks,

Problem with socket connections through a proxy server.

People,
I set the system properties to use a proxy server so my application can fetch data from servers located outside my local network:
System.setProperty("socksProxyPort", port);
System.setProperty("socksProxyHost", proxy_addy);Then, when I attempt to stabilish a connection:
s = new Socket(this.getHost(), port);It hangs.
I appreciate any help since my available Java documentation is quite obscure regarding proxy servers.

Is the proxy on another machine? Try it's IP. If
not, replace 'proxy' with 'localhost'.
- SaishYes, it is another machine.
            byte x[] = {(byte)aaa,(byte)bbb,(byte)ccc,(byte)ddd};
            s = new Socket(new Proxy(Proxy.Type.SOCKS, new InetSocketAddress(InetAddress.getByAddress(x), 8080)));
            s.connect(new InetSocketAddress(this.getHost(), port));Again, it hung.

Problem with socket connection

have my gps reciver connected to the usb port - i have a daemon gpsd running which makes data available on tcp port 2947 for querying. when i do telnet, it gives proper data.
but when i open a socket connection using java, it does not print anything as output. actually telnet asks for an escape charatcer so i am sending "r" initially to the server but still the program does not print anything as output.
here is my java code -
import java.io.*;
import java.net.Socket;
public class test2
public static void main(String[] args)
try
Socket s = new Socket("localhost",2947);
PrintWriter out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(
s.getOutputStream())),true);
out.println("r");
BufferedReader in = new BufferedReader(new InputStreamReader(s.getInputStream()));
String line;
while(true)
line = in.readLine();
System.out.println(line);
catch (Exception e)
or sometimes it even shows error as
Exception in thread "main" java.net.SocketException: Invalid argument or cannot assign requested address
at java.net.PlainSocketImpl.socketConnect(Native Method)
and this is the output which i get on telnet -
ot@localhost ~]# telnet localhost 2947
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

Actually the problem does not seem to be in the code because i tried some basic client server programs (without any gpsd etc in picture) and even they are not working in linux though they work perfectly in windows (on the same machine). In linux it shows exception
My socket programs dont work in linux it shows error -

i have removed the firewall settings etc and it still doesnot work in linux
what could be the cause for this?

Establishing a socket connection between a .swf file and a socket-test program (TCP/IP builder - Windows), in AS3.

I have an issue with a college project I'm working on.
Using Actionscript 3, I made a simple .swf program, an animated, interactive smiley, that 'reacts' to number inputs in a input-box.
For the sake of the project, I now need to make the framework for establishing a socket connection with the smiley .swf, and another program.
This is where I encounter issues. I have very little knowledge of AS3 programming, so I'm not certain how to establish the connection - what's required code-wise for it, that is.
To test the connection, I'm attempting to use the "TCP/IP builder" program from windows, which lets me set up a server socket. I need to program the .swf file into a client - to recognize it, connect to it, then be able to receive data (so that the data can then be used to have the smiley 'react' to it - like how it does now with the input-box, only 'automatically' as it gets the data rather than by manual input).
My attempts at coding it are as follows, using a tutorial (linked HERE):
//SOCKET STUFF GOES HERE
    var socket:XMLSocket;
    stage.addEventListener(MouseEvent.CLICK, doConnect);
// This one connects to local, port 9001, and applies event listeners
    function doConnect(evt:MouseEvent):void
    stage.removeEventListener(MouseEvent.CLICK, doConnect);
    socket = new XMLSocket("127.0.0.1", 9001);
    socket.addEventListener(Event.CONNECT, onConnect);
    socket.addEventListener(IOErrorEvent.IO_ERROR, onError);
// This traces the connection (lets us see it happened, or failed)
    function onConnect(evt:Event):void
        trace("Connected");
        socket.removeEventListener(Event.CONNECT, onConnect);
        socket.removeEventListener(IOErrorEvent.IO_ERROR, onError);
        socket.addEventListener(DataEvent.DATA, onDataReceived);
        socket.addEventListener(Event.CLOSE, onSocketClose);
        stage.addEventListener(KeyboardEvent.KEY_UP, keyUp);
    function onError(evt:IOErrorEvent):void
        trace("Connect failed");
        socket.removeEventListener(Event.CONNECT, onConnect);
        socket.removeEventListener(IOErrorEvent.IO_ERROR, onError);
        stage.addEventListener(MouseEvent.CLICK, doConnect);
// Here, the flash tracks what keyboard button is pressed.
// If 'q' is pressed, the connection ends.
        function keyUp(evt:KeyboardEvent):void
        if (evt.keyCode == 81) // the key code for q is 81
            socket.send("exit");
        else
            socket.send(evt.keyCode);
// This one should handle the data we get from the server.
        function onDataReceived(evt:DataEvent):void
        try {
            trace("From Server:", evt.data );
        catch (e:Error) {
            trace('error');
    function onSocketClose(evt:Event):void
        trace("Connection Closed");
        stage.removeEventListener(KeyboardEvent.KEY_UP, keyUp);
        socket.removeEventListener(Event.CLOSE, onSocketClose);
        socket.removeEventListener(DataEvent.DATA, onDataReceived);
Trying to connect to the socket gives me either no result (other than a 'connection failed' message when I click the .swf), or the following error:
Error #2044: Unhandled securityError:. text=Error #2048: Security sandbox violation: file:///C|/Users/Marko/Desktop/Završni/Flash%20documents/Smiley%5FTCP%5FIP%5Fv4.swf cannot load data from 127.0.0.1:9001.
    at Smiley_TCP_IP_v4_fla::MainTimeline/doConnect()[Smiley_TCP_IP_v4_fla.MainTimeline::frame1:12]

Tried adding that particular integer code, ended up with either errors ("use of unspecified variable" and "implicit coercion") , or no effect whatsoever (despite tracing it).
Noticed as well that the earlier socket code had the following for byte reading:
"sock.bytesAvailable > 0" (reads any positive number)
...rather than your new:
"sock.bytesAvailable != 0" (reads any negative/positive number)
Any difference as far as stability/avoiding bugs goes?
So then, I tried something different: Have the program turn the "msg" string variable, into a "sentnumber" number variable. This seemed to work nicely, tracing a NaN for text (expected), or tracing the number of an actual number.
I also did a few alterations to the input box - it now no longer needs the 'enter' key to do the calculation, it updates the animation after any key release.
With all this considered and the requirements of the project, I now have a few goals I want to achieve for the client, in the following order of priority:
1) Have the "sentnumber" number variable be recognized by the inputbox layer, so that it puts it into the input box. So in effect, it goes: Connect -> Send data that is number (NaN's ignored) -> number put into input box -> key press on client makes animation react. I optionally might need a way to limit the number of digits that the animation reacts to (right now it uses 1-3 digit numbers, so if I get sent a huge number, it might cause issues).
- If the NaN can't be ignored (breaks the math/calculus code or some other crash), I need some way of 'restricting' the data it reads to not include NaN's that might be sent.
- Or for simplicity, should I just detect the traced "NaN" output, reacting by setting the number variable to be "0" in such cases?
2) After achieving 1), I'll need to have the process be automatic - not requiring a keyboard presses from the client, but happening instantly once the data is sent during a working connection.
- Can this be done by copying the huge amounts of math/calculus code from the inputbox layer, into the socket layer, right under where I create the "sentnumber" variable, and modifying it delicately?
3) The connection still has some usability and user issues - since the connection happens only once, on frame 1, it only connects if I already have a listening server when I run the client, and client can't re-connect if the server socket doesn't restart itself.
I believe to do this, I need to make the connection happen on demand, rather than once at the start.
For the project's requirement, I also need to allow client users to define the IP / port it's going to connect to (since the only alternative so far is editing the client in flash pro).
In other words, I need to make a "Connect" button and two textboxes (for IP and port, respectively), which do the following:
- On pressing "Connect", the button sets whatever is in the text boxes as the address of the IP and port the socket will connect to, then connects to that address without issues (or with a error message if it can't due to wrong IP/port).
- The connection needs to work for non-local addresses. Not sure if it can yet.
- On re-pressing connect, the previous socket is closed, then creates a new socket (with new IP/port, if that was altered)
It seems like making the button should be as simple as putting the existing socket code under the function of a button, but it also seems like it's going to cause issues similar to the 'looping frames' error.
4) Optional addition: Have a scrolling textbox like the AIR server has, to track what the connection is doing on-the-fly.
The end result would be a client that allows user to input IP/Port, connects on button press (optionally tracking/display what the socket is doing via scrollbox), automatically alters the smiley based on what numbers are sent whilst the connection lasts, and on subsequent button presses, makes a new connection after closing off the previous one.
Dropbox link to new client version:
https://www.dropbox.com/s/ybaa8zi4i6d7u6a/Smiley_TCP_IP_v7.fla?dl=0
So, starting from 1), can I, and how can I, get the number variable recognized by "inputbox" layer's code? It keeps giving me 'unrecognized variable' errors.

File Connection and Socket Connection in nokia 7710

Hello,
i want to transfer some data from my PC to Nokia 7710 either using File Transfer or socket connection
For file transfer, where do i need to put my file i.e. which files does nokia 7710 allow j2me programs to access? Is is ok if the file i transfer is a plain txt file? i am using jsr 75 api for reading from the file, so what file location will i give in my program, in Nokia 7710, there are two memory drives Device and Memory Stick, so how can i access these files via a j2me program running on the cell?
If i use socket connection, how will the phone recognize PC's ipaddress? Do i need to configure it? Also my Nokia 7710 is connected to the PC via a cable attached to USB port, so what port numbers do i specify in my j2me client program that will run on the phone and normal java server program that will run on the PC
please help me out, this is very important for me
thank you

Hi Steve, Would you mind to give a a piece of code to solve this problem
This is my code :
 is = sc.openInputStream();
 os = sc.openOutputStream();
 os.write(("HELO there" + "\r\n").getBytes());
 os.write(("EHLO" + "\r\n").getBytes());
 os.write(("AUTH LOGIN" + "\r\n").getBytes());
 os.write(("dHVnYXNha2hpci50cmlhZGl0eWFAZ21haWwuY29t" + "\r\n").getBytes());
 os.write(("dGEuZW1haWxjbGllbnQ=" + "\r\n").getBytes());
 os.write(("MAIL FROM:<"+ from +">\r\n").getBytes());
 os.write(("RCPT TO:<"+ to + ">\r\n").getBytes());
 os.write("DATA\r\n".getBytes());
 // stamp the msg with date
 os.write(("Date: " + new Date() + "\r\n").getBytes());
 os.write(("From: "+from+"\r\n").getBytes());
 os.write(("To: "+to+"\r\n").getBytes());
 os.write(("Subject: "+subject+"\r\n").getBytes());
 os.write((msg+"\r\n").getBytes()); // message body]
 os.write(".\r\n".getBytes());
 os.write("QUIT\r\n".getBytes());
 StringBuffer sb = new StringBuffer();
 int ch = 0;
 while((ch = is.read()) != -1) {
 sb.append((char) ch);
 si.setText("SMTP server response - " + sb.toString());but it doesn't work,...
