A remote host refused an attempted connect operation

I have been tasked with putting together a demo of Adobe Interactive Forms on our development system, and I'm following the steps listed in the SAP How-To guide, "How To... Create Online and Offline Forms in Web Dynpro for Java."
The demo form (as described in the How-To) has been created and deployed from a NetWeaver 2004s to our Application Server 6.40 (with all the latest patches). When run, however, I get a 500 Internal Error:
      <b>java.net.ConnectException: A remote host refused an attempted connect operation.</b>
Our BASIS team has confirmed that ADS is configured correctly on the server, per SAP Note 944221.
Any suggestions on the cause and possible fixes would be greatly appreciated.
<b>Addendum:</b>
Here is the exception chain:

Hi Nick,
Can you verify the ADS connection using the web service test tool? Go to http://myhost:50000/, choose web services, choose the 1st one (Adobe Document Services?), choose test, don't enter any values (leave the default values) and choose test (or something very similar, I don't have access to a server right now to verify it). You should get a login screen where you need to login with "ADSUser". Finally you should see the request and response where the response status code must be "200 OK" (and the response content-type should not be text/html; that's when a logon screen html page is returned, e.g. if the password is expired).
If it fails somewhere, try it again using the FQHN, e.g. http://myhost.mydomain.com:50000/ (I think we had a similar issue once).
If the web service test doesn't work, there's definitely a problem with the ADS configuration. If the web service does work, check the connection settings in Visual Administrator <a href="http://help.sap.com/saphelp_nw04s/helpdata/en/43/f3fcf604777062e10000000a1553f6/frameset.htm">Setting Up Basic Authentication in a Java Environment</a> (or the ABAP and/or SSL version of the same document).
Kind regards,
Sigiswald

10G dbconsole: A remote host refused an attempted connect operation.

We have 10.2 running on AIX. I previously had dbconole running fine, however, something was changed and now when I log into dbconsole I get the error "IOException in sending Request :: A remote host refused an attempted connect operation.". I can still administer database stuff (user, tablespaces) but any operation that tries to access the host fails. For instance I can't schedule a job nor change the operating system credentials. What's really wierd is that on the home page it shows database down, listener down, and agent failed. Obviously, the database and the listener are not down or I wouldn't even be able to get in.
Help appreciated.

SMD Issue: A remote host refused an attempted connect operation

Hi all,
I am installing SMD agent 7.2 on managed system which is ABAP+JAVA 7.0. I Have successfully installed SMD agent 7.2 on Managemd system. Now, i need to configure its Introcope agent for JAVA system in sOlution manager. when i go to RCA->MAnaged system->setup wizard, it successfully configures it in further screens.
However, wehn i go to RCA->MAnaged system->INtroscope agent and select the respective JAVA SID for which I installed sMD agent, it does not display the server node of jAVA for that system. Also when I check in the logs of sMG agent in the managed system, I get the below error;
location:/usr/sap/sMD/SMDA97/log/SMDAgentApplication.0.log
Error: A remote host refused an attempted connect operation
Can anyone help me solving this issue?
REgards,
FAisal

Hi Guilherme,
Thanks for your reply.
I have checked in agent administration screen. The agent is successfully assigned. I only see a problem while solman talking to the managed system on P4 port. I believe I have to open or do some administration of this P4 port. But where I am not sure.
I mean while installed another SMD Agent on another J2EE server and it worked instantly!
Can you help?
Regards,
Faisal

I guess, that you have Java proxy libraries in the EAR file. Remove them before deploying.

[MFC] Error Importing logs using SCP - "Error while downloading file. The remote host has terminated the connection"

Background:
In order to transfer logs to MFC, we had to use an intermediate logging server in our OOB network. When this logging server crashed we had to rebuild the server with new hardware and SCP no longer worked.
Issue:
The host key changed on the new server and had to be manually updated. We suspected it was related to the hosts key but had difficulty finding where the known hosts info was stored.
Solution:
Go to your install location of MFC and remove the known_hosts file. In our case the file was located at: "D:\Program Files\IronPort Systems\Mail Flow Central\mailFC\tmp\known_hosts". Instead of removing the file, we renamed it to known_hosts.old and restarted the MFC service. Afterwards we could see all the old logs importing.
The issue itself was not difficult to resolve, it just took more time than expected for something that would seem straightforward. To complicate things, we even raised a query to customercare who came back saying that they do not support the server on which MFC is running. But clearly the source of the issue was related to the application rather than the server itself.

Thanks for your comment qetzacoatl, however I don't this this will work for me, I am on a team, and we need to be able to check-in/out files and make sure we don't override eachothers work. I also don't want to have to use 2 programs to accomplish the task one should be able to do. Its now 3 weeks going and I can't get any work done, it seems like its getting worse. Nobody from Adobe seems to want to comment on my thread at all....So maybe I should just find a completely new solution and get rid of DW all together, Aptana is looking VERY nice right about now.

Detecting When a Non-Blocking Socket Is Closed by the Remote Host

Hi,
Using NIO non blocked sockets how do I detect when a Non-Blocking Socket Is Closed by the Remote Host?
What I have read is:
The only way to detect that the remote host has closed the connection is to attempt to read or write from the connection. If the remote host properly closed the connection, read() will return -1. If the connection was not terminated normally, read() and write() will throw an exception.
I have written a server test program using NIO and an applet connecting to the server program via sockets.
When I after a successful connection shuts down the browser following happens: The code below comes in an endless loop though mySelector.select returns 0 every time. (The selector is registered for OP_READ). size = 1.
while (true) {
int n = mySelector.select();
int size = mySelector.keys().size();
if (n == 0) continue;
Is this an expected result?
How do I get to know what client has lost connection?
My environment:
W2000
java 1.4.1 build 1.4.1_01-b01
Browser used: IE 5.0
Many thanks for your help on this matter!
Regards Magnus Wistr�m

What you're doing looks OK to me.
I wonder whether your thread is being interrupted by Thread.intterupt() somewhere. Try putting a Thread.interrupted() before the select call.

Please guide me how to troubleshoot this problem.
Thanks in advance.

Yes, I have changed that previously for testing purpose.
Now i have kept DATAPUMP port and TARGET MGR port to 7809 . Still i am getting the error.
I also checked with TELNET if the port is blocked but its not.
Below is the report of my DATAPUMP and the attempt of TELNET Command.

Connection Closed forcibly by the remote host

Hi,
I am trying to print a file on the Client machine by getting the file object from the Server. For this, I used an Applet to call the Servlet and in return the Servlet will send the file object as response. It worked well for me, but I got the following error at one time.
[5/2/08 8:55:00:087 CDT] 0000001d SRTServletReq E SRVE0133E: An error occurred while parsing parameters. java.io.IOException: Async IO operation failed, reason:

I am not able find the exact reason for this exception, because I couldn't reproduce the same scenario. Can any one tell the exact reason for this exception and how to solve this problem.
Thank You.

Remote host said: 550 5.2.1 Mail from 209.X.X.X refused: spa

Dear All,
My Friend is facing a problem he is not able to send mails from outside for e.g yahoo.com his mx is natted on the firewall to my exchange server.
Sender gets a bounce back mail stating below: -
<XXX>:
203.X.X.X does not like recipient.
Remote host said: 550 5.2.1 Mail from 209.X.X.X refused: spam site.
Giving up on 203.X.X.X.
Sorry but i dont know whether this forum should answer my querries which are actually of my friends.
But if you could it would be really helpful.
Thanks in advance.
Regards,
Ranjit

Hi Ranjit,
203.X.X.X does not like recipient.
Remote host said: 550 5.2.1 Mail from 209.X.X.X refused: spam site.
Giving up on 203.X.X.X.
implies that the recipient server is using antispam or blacklist software to refuse connections from certain IP addresses, including the 209.x.x.x address you cited.
I would consider using an RBL lookup tool such as
http://www.mxtoolbox.com/blacklists.aspx to check the 209.x.x.x address against different RBLs.
If it turns out that it is indeed listed, you would need to go to the respective listing site to see how to get off their list.
( I am not affiliated with mxtoolbox, they just have a convenient lookup tool on their site )

I've also tried running against JRE 1.5, and tried saving the jnlp file and running that directly from javaws, all attempts produce the same result. I am able to connect to port 8890 from my machine. An strace seems to suggest that it sends and receives from port 8890 but then gets a Connection reset by peer.
Furthermore I've also tried running it through localhost using an ssh tunnel to the elom, again, same result.
I've now run out of ideas of what could be causing this issue, any help would be greatly appreciated.
TIA
Regards

FYI, I downloaded the debian package of libstdc++5 from http://ftp.us.debian.org/debian/pool/main/g/gcc-3.3/libstdc++5_3.3.6-18_i386.deb
After installing that on Kubuntu, the console works fine.

Is it possible and how to find out what host, if any, is connected to a remote PXI prior to switching execution target programmatically or in devlopment environment?

Is it possible and how to find out what host, if any, is connected to a remote PXI prior to switching execution target programmatically or in devlopment environment?

This functionality is not available in LabVIEW RT. If you attempt to switch execution target to an RT controller already targetted by someone else, it will tell you too many hosts are connected and fail. Of course if it allows you to switch, then no one was connected. By attempting to switch execution target you can use the message above to determine if anyone is targetted or not, but if someone is, there is no way to determine who.
If you are concerned about this sort of thing, you might check the RT target options in LabVIEW RT to change the IP access list for hosts that are allowed to switch execution target to it.

TcpListener not working on Azure: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host

Hi Everybody,
i'm playing a little bit with Windows Azure and I'm blocked with a really simple issue (or maybe not).
I've created a Cloud Service containing one simple Worker Role. I've configured an EndPoint in the WorkerRole configuration, which allows Input connections via tcp on port 10100.
Here the ServiceDefinition.csdef file content:
<?xml version="1.0" encoding="utf-8"?>
<ServiceDefinition name="EmacCloudService" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition" schemaVersion="2014-01.2.3">
<WorkerRole name="TcpListenerWorkerRole" vmsize="Small">
<Imports>
<Import moduleName="Diagnostics" />
<Import moduleName="RemoteAccess" />
<Import moduleName="RemoteForwarder" />
</Imports>
<Endpoints>
<InputEndpoint name="Endpoint1" protocol="tcp" port="10100" />
</Endpoints>
</WorkerRole>
</ServiceDefinition>
This WorkerRole is just creating a TcpListener object listening to the configured port (using the RoleEnvironment instance) and waits for an incoming connection. It receives a message and returns a hardcoded message (see code snippet below).
namespace TcpListenerWorkerRole
using System;
using System.Net;
using Microsoft.WindowsAzure.ServiceRuntime;
using System.Net.Sockets;
using System.Text;
using Roche.Emac.Infrastructure;
using System.IO;
using System.Threading.Tasks;
using Microsoft.WindowsAzure.Diagnostics;
using System.Linq;
public class WorkerRole : RoleEntryPoint
public override void Run()
// This is a sample worker implementation. Replace with your logic.
LoggingProvider.Logger.Info("TcpListenerWorkerRole entry point called");
TcpListener listener = null;
try
listener = new TcpListener(RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint1"].IPEndpoint);
listener.ExclusiveAddressUse = false;
listener.Start();
LoggingProvider.Logger.Info(string.Format("TcpListener started at '{0}:{1}'", RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint1"].IPEndpoint.Address, RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint1"].IPEndpoint.Port));
catch (SocketException ex)
LoggingProvider.Logger.Exception("Unexpected exception while creating the TcpListener", ex);
return;
while (true)
Task.Run(async () =>
TcpClient client = await listener.AcceptTcpClientAsync();
LoggingProvider.Logger.Info(string.Format("Client connected. Address='{0}'", client.Client.RemoteEndPoint.ToString()));
NetworkStream networkStream = client.GetStream();
StreamReader reader = new StreamReader(networkStream);
StreamWriter writer = new StreamWriter(networkStream);
writer.AutoFlush = true;
string input = string.Empty;
while (true)
try
char[] receivedChars = new char[client.ReceiveBufferSize];
LoggingProvider.Logger.Info("Buffer size: " + client.ReceiveBufferSize);
int readedChars = reader.Read(receivedChars, 0, client.ReceiveBufferSize);
char[] validChars = new char[readedChars];
Array.ConstrainedCopy(receivedChars, 0, validChars, 0, readedChars);
input = new string(validChars);
LoggingProvider.Logger.Info("This is what the host sent to you: " + input+". Readed chars=" + readedChars);
try
string orderResultFormat = Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\xB")) + @"MSH|^~\&|Instrument|Laboratory|LIS|LIS Facility|20120427123212+0100||ORL^O34^ORL_O34| 11|P|2.5.1||||||UNICODE UTF-8|||LAB-28^IHE" + Environment.NewLine + "MSA|AA|10" + Environment.NewLine + @"PID|||patientId||""""||19700101|M" + Environment.NewLine + "SPM|1|sampleId&ROCHE||ORH^^HL70487|||||||P^^HL70369" + Environment.NewLine + "SAC|||sampleId" + Environment.NewLine + "ORC|OK|orderId|||SC||||20120427123212" + Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\x1c\x0d"));
writer.Write(orderResultFormat);
catch (Exception e)
LoggingProvider.Logger.Exception("Unexpected exception while writting the response", e);
client.Close();
break;
catch (Exception ex)
LoggingProvider.Logger.Exception("Unexpected exception while Reading the request", ex);
client.Close();
break;
}).Wait();
public override bool OnStart()
// Set the maximum number of concurrent connections
ServicePointManager.DefaultConnectionLimit = 12;
DiagnosticMonitor.Start("Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString");
RoleEnvironment.Changing += RoleEnvironment_Changing;
return base.OnStart();
private void RoleEnvironment_Changing(object sender, RoleEnvironmentChangingEventArgs e)
// If a configuration setting is changing
LoggingProvider.Logger.Info("RoleEnvironment is changing....");
if (e.Changes.Any(change => change is RoleEnvironmentConfigurationSettingChange))
// Set e.Cancel to true to restart this role instance
e.Cancel = true;
As you can see, nothing special is being done. I've used the RoleEnvironment.CurrentRoleInstance.InstanceEndpoints to retrieve the current IPEndpoint.
Running the Cloud Service in the Windows Azure Compute Emulator everything works fine, but when I deploy it in Azure, then I receive the following Exception:
2014-08-06 14:55:23,816 [Role Start Thread] INFO EMAC Log - TcpListenerWorkerRole entry point called

I've already tried to configure an internal port in the ServiceDefinition.csdef file, but I get the same exception there.
As you can see, the client can connect to the service (the log shows the message: Client connected with the address) but when it tries to read the bytes from the stream, it throws the exception.
For me it seems like Azure is preventing the retrieval of the message. I've tried to disable the Firewall in the VM in Azure and the same continues happening.
I'm using Windows Azure SDK 2.3
Any help will be very very welcome!
Thanks in advance!

hi Javier,
I changed your code like this:
private AutoResetEvent connectionWaitHandle = new AutoResetEvent(false);
public override void Run()
TcpListener listener = null;
try
listener = new TcpListener(
RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint"].IPEndpoint);
listener.ExclusiveAddressUse = false;
listener.Start();
catch (SocketException se)
return;
while (true)
IAsyncResult result = listener.BeginAcceptTcpClient(HandleAsyncConnection, listener);
connectionWaitHandle.WaitOne();
The HandleAsync method is your "While (true)" code:
private void HandleAsyncConnection(IAsyncResult result)
TcpListener listener = (TcpListener)result.AsyncState;
TcpClient client = listener.EndAcceptTcpClient(result);
connectionWaitHandle.Set();
NetworkStream netStream = client.GetStream();
StreamReader reader = new StreamReader(netStream);
StreamWriter writer = new StreamWriter(netStream);
writer.AutoFlush = true;
string input = string.Empty;
try
char[] receivedChars = new char[client.ReceiveBufferSize];
// LoggingProvider.Logger.Info("Buffer size: " + client.ReceiveBufferSize);
int readedChars = reader.Read(receivedChars, 0, client.ReceiveBufferSize);
char[] validChars = new char[readedChars];
Array.ConstrainedCopy(receivedChars, 0, validChars, 0, readedChars);
input = new string(validChars);
// LoggingProvider.Logger.Info("This is what the host sent to you: " + input + ". Readed chars=" + readedChars);
try
string orderResultFormat = Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\xB")) + @"MSH|^~\&|Instrument|Laboratory|LIS|LIS Facility|20120427123212+0100||ORL^O34^ORL_O34| 11|P|2.5.1||||||UNICODE UTF-8|||LAB-28^IHE" + Environment.NewLine + "MSA|AA|10" + Environment.NewLine + @"PID|||patientId||""""||19700101|M" + Environment.NewLine + "SPM|1|sampleId&ROCHE||ORH^^HL70487|||||||P^^HL70369" + Environment.NewLine + "SAC|||sampleId" + Environment.NewLine + "ORC|OK|orderId|||SC||||20120427123212" + Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\x1c\x0d"));
writer.Write(orderResultFormat);
catch (Exception e)
// LoggingProvider.Logger.Exception("Unexpected exception while writting the response", e);
client.Close();
catch (Exception ex)
//LoggingProvider.Logger.Exception("Unexpected exception while Reading the request", ex);
client.Close();
Please try it. For this error message, I suggest you could refer to this thread (http://stackoverflow.com/questions/6173763/using-windows-azure-to-use-as-a-tcp-server

Can't see design view after changing connections file from localhost to a remote host & back again

I was using localhost to test files before changing the connections document over to a remote host, since I couldn't get dreamweaver to connect to the remote host, I changed back to localhot. My files are all .php files. This is a dynamic site. After I changed my connection back to my local host my design view no longer works. It's competly grey with 3 small icons at the top on the left. I can view in live view and I can view in the browser. But no longer in design view after being able to for 6 months. The 3 icons are a hard drive case, a document, and a link symbol . When I click in code view the design view turns grey when I click in design view it turns white. I am using wamp for the localhost, Windows XP home, Dreamweaver CS5. Can someone please tell me how to go back to design view. This happens with any & all files including non dynamic .html files. Also having a problem connecting to my remote host. using godaddy, and they have tried with me for 2 hours to connect, I just keep getting password is incorrect. Thank you for any help, Stacey

I would also recommend clearing the Site cache, which may help with the connection failure. To do so, choose Site > Advanced > Recreate Site Cache.
After doing so, be sure to go back into your Site Setup, and make sure the FTP address, user name, and password are all correct. (Click the Test button in there to verify.)
If that doesn't help with getting connected to your server, you might try an alternate FTP client (e.g. FileZilla) to just make sure you are entering the right connection information. It could be that GoDaddy is having some issue, or maybe you just mistyped something (I know I do this often when I type too fast).
As for the issue with Design View, try clearing the Dreamweaver cache. Instructions are here: http://forums.adobe.com/thread/494811
You might also try toggling the location of Design View. That is, when in Split View, choose View > Design View On Left. Then, choose that menu option again to reset the location back to the right.
Resetting the workspace might also be recommended. Window > Worksapce Layout > Reset 'name of current workspace'
