I'm using the WCF4.0 template -REST. I'm trying to make a method that uploads a file using a stream.
The problem always occur at
Stream serverStream = request.GetRequestStream();
Class for streaming:
namespace LogicClass
{
public class StreamClass : IStreamClass
{
public bool UploadFile(string filename, Stream fileStream)
{
try
{
FileStream fileToupload = new FileStream(filename, FileMode.Create);
byte[] bytearray = new byte[10000];
int bytesRead, totalBytesRead = 0;
do
{
bytesRead = fileStream.Read(bytearray, 0, bytearray.Length);
totalBytesRead += bytesRead;
} while (bytesRead > 0);
fileToupload.Write(bytearray, 0, bytearray.Length);
fileToupload.Close();
fileToupload.Dispose();
}
catch (Exception ex) { throw new Exception(ex.Message); }
return true;
}
}
}
REST project:
[WebInvoke(UriTemplate = "AddStream/{filename}", Method = "POST", BodyStyle = WebMessageBodyStyle.Bare)]
public bool AddStream(string filename, System.IO.Stream fileStream)
{
LogicClass.FileComponent rest = new LogicClass.FileComponent();
return rest.AddStream(filename, fileStream);
}
Windows Form project: for testing
private void button24_Click(object sender, EventArgs e)
{
byte[] fileStream;
using (FileStream fs = new FileStream("E:\\stream.txt", FileMode.Open, FileAccess.Read, FileShare.Read))
{
fileStream = new byte[fs.Length];
fs.Read(fileStream, 0, (int)fs.Length);
fs.Close();
fs.Dispose();
}
string baseAddress = "http://localhost:3446/File/AddStream/stream.txt";
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(baseAddress);
request.Method = "POST";
request.ContentType = "text/plain";
Stream serverStream = request.GetRequestStream();
serverStream.Write(fileStream, 0, fileStream.Length);
serverStream.Close();
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
int statusCode = (int)response.StatusCode;
StreamReader reader = new StreamReader(response.GetResponseStream());
}
}
I've turned off the firewall and my Internet connection, but the error still exists. Is there a better way of testing the uploading method?

"Actively refused it" means that the host sent a reset instead of an ack when you tried to connect. It is therefore not a problem in your code. Either there is a firewall blocking the connection or the process that is hosting the service is not listening on that port. This may be because it is not running at all or because it is listening on a different port.
Once you start the process hosting your service, try netstat -anb (requires admin privileges) to verify that it is running and listening on the expected port.
update: On Linux you may need to do netstat -anp instead.
You don't have to restart the PC. Restart IIS instead.
Run -> 'cmd'(as admin) and type "iisreset"
You must set up your system proxy
You have to go through this path

I got a similar error message like TCP error code 10061: No connection could be made because the target machine actively refused it in my current project. I find this 10061 error code cannot distinguish the case that the service endpoint is not started and the case that it is blocked by the firewall. Often, the firewall can be switched off, but the problem is still there.
You can test your code in the below two ways.
Insert code to get time A that service is started and time B that client sends the request to the server. If B is earlier than A, it can cause this problem.
Change your server port to another port that is also available in the system. You will find the same error code reported.
Above is my fix. It works on my machine. I hope it helps!
Check if any other program is using that port.
If an instance of the same program is still active, kill that process.
I had a similar issue. In my case the service would work fine on the developer machine but fail when on a QA machine. It turned out that on the QA machine the application wasn't being run as an administrator and didn't have permission to register the endpoint:
HTTP could not register URL http://+:12345/Foo.svc/]. Your process does
not have access rights to this namespace (see
http://go.microsoft.com/fwlink/?LinkId=70353 for details).
Refer here for how to get it working without being an admin user: https://stackoverflow.com/a/885765/38258
If you use WCF storm, can you even log-in to the WCF service endpoint? If not, and you are hosting it in a Windows service, you probably forgot to register that namespace. It's not very well advertised that this step is required, and it is actually annoying to do.
I use this tool to do this; it automates all those cumbersome steps.
Check whether the port number in file Web.config of your webpage is the same as the one that is hosted on IIS.
I had the same problem on my web server "No connection could be made because the target machine actively refused it 161.x.x.235:5672". I asked the Admin to open the port 5672 on the web server, then it worked fine.
I had a similar problem
rejecting localhost and 127.0.0.1.
cmd(admin) netstat -anb found the port running on 169.254.80.80 (dont know were that ip came from because my network ip was 10.0.0.5.
after putting in this IP it worked.
This Gives correct IP:
IPAddress ipAddress = ipHostInfo.AddressList[0];
Console.WriteLine(ipAddress.ToString());
I also faced problem in .Net Remoting Service in C#.
I got it solved in 3 steps:
Change Port of Protocol in all the files whereever it is being used.
Run your Host Server Program and make it active.
Now run your client program.
I could not restart IIexpress. This is the solution that worked for me
Cleaned the build
Rebuild
With this error I was able to trace it, thanks to #Yaur, you need to basically check the service (WCF) if it's running and also check the outbound and inbound TCP properties on your advance firewall settings.
With similar pattern, my rest client is calling the service API, the service called successfully when debugging, but not working on the published code. Error was: Unable to connect to the remote server.
Inner Exception: System.Net.Sockets.SocketException (0x80004005): No connection could be made because the target machine actively refused it serviceIP:443 at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Exception& exception)
Resolution: Set the proxy in Web config.
<system.net>
<defaultProxy useDefaultCredentials="true">
<proxy proxyaddress="http://proxy_ip:portno/" usesystemdefault="True"/>
</defaultProxy>

I had a similar issue. In my case VPN proxy app such as Psiphon ، changed the proxy setup in windows so follow this :
in Windows 10, search change proxy settings and turn of use proxy server in the manual proxy
Make Sure all services used by your application are on, which are using host and port to utilize them . For e.g, as in my case, This error can come, If your application is utilizing a Redis server and it is not being able to connect to it on given port and host, thus producing this error .
For my case, I had an Angular SLA project template with ASP.NET Core.
I was trying to run the IIS Express from the Visual Studio WebUI solution, triggering the "Actively refused it" error.
The problem, in this case, wasn't connected with the Firewall blocking the connection.
It turned out that I had to run the Angular server independently of the Kestrel run because the Server was expecting the UI to run on a specific port but wasn't actually.
For more information, check the official Microsoft documentation.
I had similar problem. In launchSettings, my IIS Express was configured on one port, and there was another launch profile that started on another ApplicationUrl with another port.
Starting the web app up with the IIS Express profile led me to have the error.
I am using the Apache ActiveMQ Artemis AMQP message broker. I started getting the "No connection could be made because the target machine actively refused it" exception when trying to send and receive messages with the broker after a reboot. On a computer where the same type of broker still worked, netstat -anb showed that the broker was listening on the expected port 5672. On the computer with the error, the broker was not listening. On the computer with the error, starting the broker resulted in the following warning's appearing in Microsoft Event Viewer's "Windows Logs > System":
The system failed to register host (A or AAAA) resource records for network adapter
with settings:
Adapter Name : {286EE2DA-3D81-41AE-VE5G-5D761FD3925E}

Either the DNS server does not support the DNS dynamic update protocol or the authoritative zone for the specified DNS domain name does not accept dynamic updates.
To register the DNS host (A or AAAA) resource records using the specific DNS domain name and IP addresses for this adapter, contact your DNS server or network systems administrator.
I was able to use the broker without error after I ran the following in a cmd.exe with administrative privileges, rebooted, and waited about fifteen minutes:
ipconfig /flushdns
ipconfig /renew
ipconfig /registerdns
Am trying to perform an ftp connection to another server.
So currently i have done
$host="server_to_connet_ip"
ftp_connect ( $host [ 21 [, int $timeout = 90 ]] )
This works totally fine when the the server to connect to doesnt limit the ip address.
Currently there is a limit on the ip address that can connect to the server and my vps ip address has already been whitelisted
How can i still perform the ftp connection with the origin ip address as my server ip address(where application is hosted) as currently each and every request i make happen to appear to be from my local computer outgoing ip address not the servers(where application is hosted) ip address
I have also checked on using curl as an alternative but i cannot figure out how.
SO in curl this would be something like
curl ftp://serverip --user myname:mypassword
But how can this be achieved in such away that when performing the ftp connection request the request will originate from my server ip address(when i host my application) not my local computer ip address.
You can't, it's not possible to spoof an IP and receive a response because the response will go to the IP that you spoofed and you aren't actually calling from there.
You need to add the IP that you will be connecting from to the whitelist on the server you are connecting to.
I created a simple android application (With MySQL database connectivity logic in php) to register a new contact. When I ran the application to the emulator (using localhost IP Address as 10.0.2.2), it was working fine. Now I want to test it on my device and I am facing connectivity issue of localhost
what should I do??
Here is my code:
#Override
protected String doInBackground(String... params) {
String reg_url="http://10.0.2.2/mobile/register.php";
String login_url="http://10.0.2.2/mobile/login.php";
}
Thanks in advance
First, make sure both your server and your device can establish a connection between each other (either they are in the same network, or the server is publicly accessible).
Then, check your server's IP address and get the port your server is running on. Use those when you establish a connection from your real device. The URL should look something like this: http://<server IP address>:<server port>/mobile/register.php.
You should look into adb reverse port forwarding. So, lets say you want your mobile's localhost:8888 to point to your local machine's localhost:8888, you can acheive it by using the following adb command:
adb reverse tcp:8888 tcp:8888
First parameter refers to the port on the device and the second on your computer.
adb reverse allows you to forward ports from your device to your host.
Let me know if you have any doubts.
Refer to the following link for more info:

I think that the connection is established ,when i write my adresse IP from the phone i get the wamp Localhost[1]
but when i run the application and enter the user s name and password i get this
(I think that is the description of the file login.php) [2]
http://i.stack.imgur.com/jSXXP.jpg // [1]
http://i.stack.imgur.com/cP8PB.jpg //[2]
i use this line to call the script php : String login_url="http://192.168.1.103:80/mobile/login.php";
We send some files across to a third party with a PHP cron job via FTP.
However sometimes we get the following error:
ErrorException [ 2 ]: ftp_put(): php_connect_nonb() failed: Operation
now in progress (115) ~ MODPATH/fileop/classes/Drivers/Fileop/Ftp.php [ 37 ]
When I say "sometimes" I mean exactly that; most times it goes across fine but about 1 in 5 times we get that error. It's not to do with the files themselves, because they will go happily if we try again.
We've found similar issues online - relating to a bug in PHP with NAT devices or to do with firewall configuration but again the implication is that if this were the case it would never work.
So, why would this work some times and not others?
ftp_set_option($ftpconn, FTP_USEPASVADDRESS, false);
This line of code before setting passivity of the connection ftp_pasv($ftpconn, true);
Solved my problem
FTP(S) uses random ports to set up data connections; an intermittent success rate indicates that not all ports are allowed by a firewall on the client and/or server machines. The port range for incoming (PASV) data connections can be set in the FTP server.
This page has a nice summary:
The easy way is to simply allow FTP servers and clients unlimited
access through your firewall, but if you like to limit their access to
"known" ports, you have to understand the 4 different scenarios.
1) The FTP server should be allowed to accept TCP connections to port
21, and to make TCP connections from port 20 to any (remote ephemeral)
port.
2) The FTP server should be allowed to accept TCP connections to port
21, AND to accept TCP connections to any ephemeral port as well!
3) The FTP client should be allowed to make TCP connections to port
21, and to accept TCP connections from port 20 to any ephemeral port.
4) The FTP client should be allowed to make TCP connections to port
21, and to make TCP connections to any other (remote ephemeral) port
as well!
So, I'm writing this answer after doing some investigation on my FTP server and reading the link you provided elitehosts.com.
I'm using FileZilla FTP server, and there is a specific setting that I had to enter to make it work. Going into the server settings, there is an area titled "Passive mode settings". In that dialog, there is an area titled "IPv4 specific", and within that area there is a setting labeled "External Server IP Address for passive mode transfers:". It's a radio button selection set, and it was on "Default", but since the FTP server is NAT'ed, I changed that radio selection from "Default" to "Use the following IP:" and entered in the external-facing IP address of my gateway provided by my ISP.
After I set this up, it worked! Not terribly sure if your FTP server is NAT'ed, but I thought I would provide the answer on this thread because it seems related.
In addition to Cees answer, I am running vsftp on ec2 and had to comment out the listen_ipv6=YES, listen=YES then "service vsftpd restart".
Although documentation says it will listen on ipv4 as well it wasn't and this resolved the issue.
For me all I had to do was to remove the ftp_pasv( $ftpconn, true ); and everything worked perfectly. I'm not yet sure why but I am trying to find out and I will surely come back when I do get the reason behind it.
This should be a comment under jj_dev2 comment, but I cannot add one due to reputation. But maybe it will be helpful for someone, so I post it here.
We had the same issue as described in the original post. In our case it worked with many customers - except one.
The solution in jj_dev2 comment did work for us. So we investigated what does ftp_set_option($conn, FTP_USEPASVADDRESS, false) actually do. And based on that we found out that in fact customer's FTPS server was configured incorrectly.
In response to PASV command (ftp_pasv($conn, true)) FTP server returns an IP address which the PHP FTP client then will use for data transfers. In our case the FTP server was returning an internal IP address and not the public IP address that we connect to. Customer had to fix their FTP server settings so FTP server would send external IP address in the PASV command response.
I have a long procedure I have written in node.js, but I'd like the PHP side of my application control kicking it off. My node is something like:
var http = require('http');
http.createServer(function (req, res) {
console.log('Got request')
try{
doProcedure()
} catch(e) {
console.log('Really bad error while trying to do the procedure:')
console.error(e.stack ? e.stack : e)
}
}).listen(8124, "127.0.0.1");
When I run this on my local machine, http://localhost:8124 will trigger things correctly. On aws, I've added the 8124 port but requests to mydomain.com:8124 aren't picked up by node.
I tried stopping httpd and then letting node listen on port 80, to rule out ports not being forwarded correctly, but it still saw nothing.
So two questions, I guess:
How to get Node listening as a daemon, so I can pass over requests? ("update user x", "update user y", "update all users", etc)
How do I ping that daemon from php to start these procedures in an AWS evironment?
Bonus question: Is there a better way I should be doing this?
Thanks all,
~Jordan
If you omit the second argument to listen(), node will listen on all IP addresses. That way you can run the same code locally to test and also on your EC2 instance.
In your catch block, you might also want to send back an HTTP error response to the client.
you should have a 10.* ip iirc for aws, your elastic/dynamic ip cant be bound to
have you tried using your server's IP address (instead of 127.0.0.1) in the createServer.listen() call?
