External HTTP > internal to the web server

Hello

I have a router ADSL with a public IP assigned, preforming NAT. This leads to a 506th PIX which leads to a Web server. The entire interior of the ADSL is on private IP addresses.

I want to allow external users access to the Web server on port 80.

I inwardly and outwardly put up ICMP connectivity (for testing only) and it works correctly.

I created a virtual server on the ADSL router that forwards port 80 traffic to the external interface of the web server. It has worked successfully for half an hour and then something in the config changed PIX and it no longer works. Here is my config PIX

  • Internal server messages no longer work when published on the web server, but not locally on the web server

    Just upgraded to 8 Captivate and for some reason my server any internal messages is no longer work on the web server.  I can test locally the lesson that always points to the Web server and it works.  Can't understand why when it is on the server it does not work.  The ashx handler that manages to post is fully accessible to the web server and DNS solves very well so I can't understand why he doesn't hit the Manager.  I use IIS to host it and a .ashx for managing for results.

    Is there maybe something new that needs to be allowed in IIS for 8 Captivate work?  .js seems to be fine and firewall is not the issue.  Short of ideas and the need for this work as soon as possible.

    Thank you very much for your help!

    Nick

    OK, finally solved.  For some reason any run under HTTPS lesson could not publish my results.  As soon as I changed to HTTP the results perfectly. All of this makes sense why I could post locally on the Web server.  Hope this saves someone else 5 days of hell.

  • start the Web server in different folders

    I developed a compiled VI (Smarts - Net .exe) that has been designed to operate in a specific folder (\Smarts-Net) and activated the Server Web page of Smarts - Net .html in the same folder.  So far so good.

    The application receives data in real time produced another of our programs and generates graphs to show "what happens".

    My clients would like run multiple instances of my program for their customers, but want to isolate their customer 'A' customer 'B' so that they cannot display the data on the other.  I can start my application using different IP ports so that I can have multiple views, but I want to further isolate the data of the customer in different folders.

    I did a 'manager' program that will create a subfolder of the folder in my main application (\Smarts-Net) so that it would appear as "\Smarts-Net\JobA" and copy all the files in the main folder in the new subfolder.  I then change the of Smarts - Net .ini file with the new pathname of the file and the new port like this number:

    [Smarts-Net]
    server.app.propertiesEnabled = True
    Server.OLE.Enabled = True
    Server.TCP.servic = "My Server computer/VI"
    server.vi.propertiesEnabled = True
    WebServer.DirectoryIndex = "index.htm"
    WebServer.LogEnabled = True
    WebServer.LogPath=C:\Smarts-Net\Logs\Smarts-Net.log
    WebServer.MimeTypes = (a LOT of Mime types in here... I left aside for this post)
    WebServer.Port = 9501
    WebServer.Enabled = True
    WebServer.RootPath=C:\Smarts-Net\JobA
    WebServer.TcpAccess = "" + c * ' "
    WebServer.ViAccess = "' + * '"
    DebugServerEnabled = False
    DebugServerWaitOnLaunch = False

    After you change the .ini file, I start the application (Smarts - Net .exe) to the new folder.

    This is where I need help.  If I try to display the VI from another computer using an address like http://snape:9600/JobA/Smarts-Net.html, I get an "HTTP 404 - File not found" error.  But, if I try to http://snape:9600 / Smarts - Net .html, I get the VI Panel!

    Thus, it seems that I can change the Port in the .ini file, but not the RootPath.  Does anyone know how to get the html to load from a different folder from the one specified when I created the application code?

    Hello Steve,.

    From your description it looks that the web server is already doing what you say you need for.

    There is a difference between the URL path, the path that is entered in the browser and the path of file system, the location of the file on the disk.

    The WebServer.RootPath token specifies the directory of the file system that corresponds to the root directory, "/", in the URL. You have specified C:\Smarts-Net\JobA as root your path so all files in this directory will be the URL of the http://mycomputer:myport / myFile. If you want the URL of http://mycomputer:myport/Logan/myFile then you need to have your root C:\Smarts-Net\ directory.

    Does make sense?

  • Activation of scripts on the Web server

    I found this, but cannot locate Scripting on the Web Server: Configuration page

    Activation of scripts on the Web server

    To use the script with a Web service, you must enable the feature on the Web of LabVIEW server. In LabVIEW, select the script on the Web Server: Configuration page in the dialog box Options to enable the use of scripts on the Web server.

  • What is the web server integrated for Windows XP Professional?

    Hello

    I would like to know what the web server integrated for Windows XP Professional.

    I don't know of a free web server like Apache or IIS.

    I want to host my site on the net using the web server integrated in XP (not IIS).

    Thanks in advance.

    It is not just any server web, other than IIS, integrated with Windows XP Professional.

    You think perhaps of Personal Web Server (PWS) which was part of the old operating systems like Windows NT.  Which no longer exists in Windows XP Professional - it has been replaced by IIS.

  • Picture POST on the web server problem

    Hi gurus

    I am trying to display a picture jpg on a web server. I tested my PHP script on the server and I am able to upload an image using a form. Now I am making an application Blackberry POST the image on the server by using the same script however when I test the code in Java, PHP tells me that nothing has been published, I don't know what I'm doing wrong but I am doing something like this:

    String mBoundary = "SUPSUPSUPSUP";
    
    /* Preparar objeto a enviar */
    
    InputStream mImagen = this.getClass().getResourceAsStream("sample.jpg");
    byte[] mBytesPostear = IOUtilities.streamToBytes(mImagen);
    
    HttpConnection mConexion = (HttpConnection) Connector.open("http://www.raspberry.com/script.php");                        
    
    /* Preparar headers del POST. Es multiformulario con POST de un archivo */
    mConexion.setRequestMethod(HttpConnection.POST);
    mConexion.setRequestProperty(HttpProtocolConstants.HEADER_CONTENT_TYPE, HttpProtocolConstants.CONTENT_TYPE_MULTIPART_FORM_DATA + ";boundary=" + mBoundary);
    mConexion.setRequestProperty(HttpProtocolConstants.HEADER_CONTENT_LENGTH, String.valueOf(mBytesPostear.length));
    mConexion.setRequestProperty( "x-rim-transcode-content", "none" );                      
    
    /* Preparar contenido de salida */
    ByteArrayOutputStream mOutput = new ByteArrayOutputStream();
    OutputStream mOS = mConexion.openOutputStream();
    
    /* Escribir contenido */
    String nuevaLinea = "\r\n";
    String contDisp="Content-Disposition:form-data; name=\"foto\";filename=\"sample.jpg\"";
    String contEnc = "Content-Transfer-Encoding: binary";
    String type="Content-Type:image/jpeg";
    
    mOutput.write(nuevaLinea.getBytes());
    mOutput.write("--".getBytes());
    mOutput.write(mBoundary.getBytes());
    mOutput.write(nuevaLinea.getBytes());
    mOutput.write(contDisp.getBytes());
    mOutput.write(nuevaLinea.getBytes());
    mOutput.write(type.getBytes());
    mOutput.write(nuevaLinea.getBytes());
    mOutput.write(contEnc.getBytes());
    mOutput.write(nuevaLinea.getBytes());
    mOutput.write(nuevaLinea.getBytes());
    mOutput.write(mBytesPostear);
    mOutput.write(nuevaLinea.getBytes());
    mOutput.write("--".getBytes());
    mOutput.write(mBoundary.getBytes());
    mOutput.write("--".getBytes());
    mOutput.write(nuevaLinea.getBytes());
    
    /**********************/
    
    /* Escribir el contenido */
    mOS.write(mOutput.toByteArray());
    
    mOutput.flush();
    mOutput.close();
    
    mOS.flush();
    mOS.close();
    
    /* Recibir respuesta del servidor */
    InputStream mIS = mConexion.openInputStream();
    int mLongitud = (int) mConexion.getLength();
    
    if (mLongitud > 0) {             
    
        int mActual = 0;
        int mBytesLeidos = 0;
        byte[] mBytes = new byte[mLongitud];
    
        while ((mBytesLeidos != mLongitud) && (mActual != -1)){
            mActual = mIS.read(mBytes, mBytesLeidos, mLongitud - mBytesLeidos);
            mBytesLeidos += mActual;
        }               
    
        String mRespuesta = new String(mBytes);
        System.out.println("Respuesta: " + mRespuesta);
    
    }
    

    I just tried to clone the header sent by Chrome when I use the form, I think that they have the same information.

    My PHP script first checks to see if something has been posted, if nothing has been validated, it returns a message so I'm able to "consume" the script on the web server and I see that the BlackBerry is the download of the data, but the answer is that nothing has been reported.

    I think I sent you the info about the server in the wrong format.

    Any help would be greatly appreciated.

    Thank you!

    Thank you all, it works fine now, I send you the length of the full header now, it works now, I'm sharking my code. Just create and instance of this object, passing the URL of web script and the bytes of the image to the constructor, then call the getRespuesta() method

    Here we have the code:

    public class PostImagen {
        private String mURL;
        private byte[] mDatos;
    
        public PostImagen(String URLServicio, byte[] Datos){
            mDatos = Datos;
            mURL = URLServicio;
        }
    
        public void getRespuesta() throws Exception {
            try {
                String mBoundary = "SUPSUP";            
    
                /* Strings a usar para el contenido */
                String nuevaLinea = "\r\n";
                String contDisp="Content-Disposition: multipart/form-data; name=\"foto\";filename=\"sample.jpg\"";
                String contEnc = "Content-Transfer-Encoding: binary";
                String type="Content-Type:image/jpeg";
    
                /* Preparar objeto a enviar */
                byte[] mBytesPostear;
                if (mDatos == null){

  • NAT problem for the Web server


    I have configured the new cisco asa 5512. I can't access our Web site from outside. We host our internal site
    This is how I configured. Internal IP of the Web server is 192.168.1.19
    in the following config, I changed my public ip of the webserver to 99.99.99.99
    Can someone help me with this.
     
    the Web server object network
    Home 192.168.1.19
    NAT 99.99.99.99 static (inside, outside)
    NAT (inside, outside) interface static tcp www www service
    outside_access_in tcp allowed access list any object Webserver eq www
    Access-group outside_access_in in interface outside

    It is not open by default, but you already enabled.

    Remember that all you need is a translation you have:

     object network Webserver host 192.168.1.19 nat (inside,outside) static 99.99.99.99

    And the list of access allowing access to desired ports:

     access-list outside_access_in permit tcp any object Webserver eq www access-list outside_access_in permit tcp any object Webserver eq 8080 access-group outside_access_in in interface outside

  • Unable to connect to port 80 on the web server on host Ubuntu guest

    I have a very strange problem. I've been running a VM of 14.04 Ubuntu on my MBP under VMware Fusion for some time. I have re-installed Yosemite during the weekend for a clean installation trying to solve some of the problems I had. I now have my Ubuntu VM up and running. All right, except that I can't hit the web server on the virtual machine.

    I can access the virtual machine in a variety of different ways!

    • Ping: I can ping
    • SSH: I can ssh in
    • psql: I can connect to the database remotely via port 5432
    • NFS: can I get the files of the virtual machine files on my hard drive
    • Tomcat: I can access my web application directly through Tomcat on port 8080

    When I do a scan of port of the virtual machine, I get this:

    Port scan started...

    Host port scan: 10.39.186.13

    Open TCP Port: 22 ssh

    Open TCP Port: 111 sunrpc

    Open TCP Port: 42060

    Open TCP Port: 55224

    Open TCP Port: 60974

    Port scan has completed...

    Port 80 is not even there. The virtual machine itself, I can access the site via port 80:

    wget xnat@xnatdev:~$ http://xnatdev.wurstworks.com

    -2015-06-22 11:20:50- http://xnatdev.wurstworks.com/

    Connection to xnatdev.wurstworks.com | 10.39.186.13 |: 80... has failed: connection refused.

    I tried switching between NAT and open networking (I know that I had to work with NAT before, but I'm willing to try anything at this point).

    I'm on OS X 10.10.3 and the most recent, and VMware Fusion 7.1.2. Any ideas on how to get this working would be greatly appreciated!

    OK, got it market. The issue was the listen directive in configuring nginx for connecting Tomcat. I'd put it domain name FULL and port 80 on the server, but something I did is the determination of the FULL domain to 127.0.0.1 instead of the IP DHCP-published name. If this does not work because the incoming request has been the full domain name of host configured in my/etc/hosts, OS, then nginx not pair together configuring nginx for the domain since listening has been screwed up.

  • Upgrading to 4 Fusion and now I can't access the web server on my Mac host

    I am running OS x 10.6.8 and I'm hosting a virtual machine running windows XP, using NAT Networking. I have a web server running on the mac I need to access from the hosted virtual machine. I used to be able to just use the IP address of the gateway in the virtual machine for the web server, but it doesn't seem to work. If I set the external IP address of the mac it seems to work, but I don't have a static IP address, so it is a pain to update every hour.

    Any help would be appreciated!

    Thank you

    Although in some cases, the IP address of the gateway works, nevertheless IMO that is a misuse and should use the address IP of VMware NAT Virtual Ethernet adapter IP address the host not IP address of gateway.

    If in a Terminal, run the following command:

    ifconfig | grep -A 3 vmnet8
    

    Then use the address after "inet" IP said at the exit.

    Example on my system:

    Last login: Mon Jan 16 12:43:00 on ttys000
    Computer:~ WKZ$ ifconfig | grep -A 3 vmnet8
    vmnet8: flags=8863 mtu 1500
        ether 00:50:56:c0:00:08
        inet 172.16.198.1 netmask 0xffffff00 broadcast 172.16.198.255
    Computer:~ WKZ$
    

    So I use 172.16.198.1 of the prompt or use the host name of the Mac (without the .local) after the addition of 172.16.198.1 and the hostname of the Mac to the guest hosts file.
