  • Why packets injected with libpcap are duplicated?

    - by r0u1i
    I'm using sharppcap in order to send packets as part of a monitoring system. Usually it works well but I've encountered the strangest bug on a hosted vista machine and I would like your help. On that virtual vista machine, injected packets are duplicated. That is, if I send a ping request using libpcap, it somehow gets duplicated and I get two requests on the destination machine. The two requests are almost identical byte-wise, and the only difference between them is that the second packet's TTL field is one minus the original packet's value. Using wireshark I can see the packet gets duplicated before it (and its clone) leave the vista machine. The problem is manifested even when using other tools for injecting packets using libpcap (namely PlayCap). Any ideas?

  • ApnsPHP in server mode (ApnsPHP_Push_Server)

    - by Kukosk
    Hi, Im using ApnsPHP for push notifications on my server, but it's a little bit slow when you have to send a lot of notifications, so i decided to Run it in the server mode. I just want it to run in cron every 1 hour, check if there are some notifications to be sent, and if yes, run it in 5 processes to be faster. I'm sending updates to my users once a day depending on the timezone they set. So i have to run it every hour, and send messages to timezones that actually have 12:00 PM. Is there any way to do this? I know there is a demonstration but i just have no clue about how to do it. A simple sample will really help. Thank you millions!!

  • Multi-Threading in .NET

    - by AIC
    Hi all.. I wrote this program, that is supposed to read about 5000 email address and send an pre-defined html mail. I am using the background worker component. The problem is this: I have wired up the method who is supposed to send the mail. But I am calling another method that is supposed to append the body html to the salutation, like public string GiveMeFullHtml(string personname) ... "Dear Mr. John Doe" + HTML ... It seems that when it hits this method call, operation completes. IUt only sends the first mail and completes. I think because the HTML string method is on another thread or sth like that. Can you give me a little insight. Do I have to get everything done in the very same method when using multi-threading? Thanks in advance

  • EasyXDM passing data issue

    - by Jeff Ryan
    I'm using rpc with XDM, and I can send simple data back and forth easily between child and parent window. But it seems to be limited to simple strings and numbers. The demos on the site only use numbers. When I try to send a json ecoded string, I get a cross domain error. When I use cors, I can make ajax requests fine, but I can't display the child page in the iframe, because the data is returned and not rendered. My question is, how can I render an iframe, and pass complex data back and forth. Or maybe I am doing something wrong?

  • Uploadify uploadSettings with scripData does not work

    - by kubilayeksioglu
    Hi everyone, I am sending a file to my Java Servlet via jQuery Uploadify, there are no problems while sending the actual file. But when I try to send some scriptData with file along, to process on Servlet it just does not send anything. Here is the JS code: $("button").click(function(){ $("#uploadify").uploadifySettings('scriptData', {'length':'0.2'}); $('#uploadify').uploadifyUpload(); }); $('#uploadify').uploadify({ 'uploader': 'assets/uploadify/uploadify.swf', 'script': 'upload', 'folder': '/uploads' }); And here is the Servlet code on the server side: out.println(res.getParameter("length")); Only output I get is null, while expecting "0.2". I just cannot get what's wrong and any kind of help will be appreciated. Thanks in advance.

  • Sending forgot password emails

    - by GeoffreyF67
    I am building a service that will have a 'forgot my password' feature. In addition to that, it will also email users when results are ready from my service. I would like to ensure delivery of my emails so I was looking around to find a service that would let me send emails. All that I've been able to find so far are services that require a user to opt-in to a list. In other words, I've been unable to find any that will let me send customized messages to individual users. I am currently using swiftmailer for php but would really like to find a service to do this...Anyone know of one? G-Man

  • http response to GET request - working in FF not Chromium

    - by Tyler
    For fun I'm trying to write a very simple server in C. When I send this response to Firefox it prints out the body "hello, world" but with Chromium it gives me a Error 100 (net::ERR_CONNECTION_CLOSED): Unknown error. This, I believe, is the relevant code: char *response = "HTTP/1.0 200 OK\r\nVary: Accept-Encoding, Accept-Language\r\nConnection: Close\r\nContent-Type: text/plain\r\nContent-Length:20\r\n\r\nhello, world"; if(send(new_fd, response, strlen(response), 0) == strlen(response)) { printf("sent\n"); }; close(new_fd); What am I missing? Thanks!

  • Sending Back Ajax variable

    - by matthewb
    Hello, I am trying to use jquery to do a client side validation to do a check and return with a error or success. I know how to echo text/html back as the response, but here's what I am trying to do. On Error, send back a message, so the user can re-submit a form. On Success, re-load the page. I am not sure how to get it to send a variable which I think will let me do either condition in jquery. Any suggestions??

  • how to use XML sent by html form?

    - by user32167
    i have html form with textarea in which i paste some XML, for example: <network ip_addr="10.0.0.0/8" save_ip="true"> <subnet interf_used="200" name="lan1" /> <subnet interf_used="254" name="lan2" /> </network> When user submit form, that data is send to Java server, so in headers i get something like that: GET /?we=%3Cnetwork+ip_addr%3D%2210.0.0.0%2F8%22+save_ip%3D%22true%22%3E%0D%0A%3Csubnet+interf_used%3D%22200%22+name%3D%22lan1%22+%2F%3E%0D%0A%3Csubnet+interf_used%3D%22254%22+name%3D%22lan2%22+%2F%3E%0D%0A%3C%2Fnetwork%3E HTTP/1.1 how can i use that in my Java applications? I need to make some calculations on that data and re-send new generated XML.

  • URL flow when writing a wizard in PHP

    - by Brian
    Hello, I am writing a basic wizard for my web site. It will have 4 steps, and each needs to have its own URL. Each step must first validate a form before moving on. If the form for a given step fails to validate, I don't want the URL to change. But if it passes, I do want it to move on. What is the preferred way to write this? Using javascript alone to validate is not secure enough. I have 2 ideas so far but I don't love either: 1) Post the form to the same script and use a header() redirect to the next step if it passes. 2) Send an ajax post to validate and then use location.href to send user to the next step if it passes. Is there a better way to do this? Thanks, Brian

  • How should I handle incomplete packet buffers?

    - by Benjamin Manns
    I am writing a client for a server that typically sends data as strings in 500 or less bytes. However, the data will occasionally exceed that, and a single set of data could contain 200,000 bytes, for all the client knows (on initialization or significant events). However, I would like to not have to have each client running with a 50 MB socket buffer (if it's even possible). Each set of data is delimited by a null \0 character. What kind of structure should I look at for storing partially sent data sets? For example, the server may send ABCDEFGHIJKLMNOPQRSTUV\0WXYZ\0123!\0. I would want to process ABCDEFGHIJKLMNOPQRSTUV, WXYZ, and 123! independently. Also, the server could send ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890LOL123HAHATHISISREALLYLONG without the terminating character. I would want that data set stored somewhere for later appending and processing. Also, I'm using asynchronous socket methods (BeginSend, EndSend, BeginReceive, EndReceive) if that matters.

  • Detect aborted connection during ASIO request

    - by Tim Sylvester
    Is there an established way to determine whether the other end of a TCP connection is closed in the asio framework without sending any data? Using Boost.asio for a server process, if the client times out or otherwise disconnects before the server has responded to a request, the server doesn't find this out until it has finished the request and generated a response to send, when the send immediately generates a connection-aborted error. For some long-running requests, this can lead to clients canceling and retrying over and over, piling up many instances of the same request running in parallel, making them take even longer and "snowballing" into an avalanche that makes the server unusable. Essentially hitting F5 over and over is a denial-of-service attack. Unfortunately I can't start sending a response until the request is complete, so "streaming" the result out is not an option, I need to be able to check at key points during the request processing and stop that processing if the client has given up.

  • Rails accepts_nested_attributes_for callbacks

    - by Rabbott
    I have two models Ticket and TicketComment, the TicketComment is a child of Ticket. ticket.rb class Ticket < ActiveRecord::Base has_many :ticket_comments, :dependent => :destroy, :order => 'created_at DESC' # allow the ticket comments to be created from within a ticket form accepts_nested_attributes_for :ticket_comments, :reject_if => proc { |attributes| attributes['comment'].blank? } end ticket_comment.rb class TicketComment < ActiveRecord::Base belongs_to :ticket validates_presence_of :comment end What I want to do is mimic the functionality in Trac, where if a user makes a change to the ticket, and/or adds a comment, an email is sent to the people assigned to the ticket. I want to use an after_update or after_save callback, so that I know the information was all saved before I send out emails. How can I detect changes to the model (ticket.changes) as well as whether a new comment was created or not (ticket.comments) and send this update (x changes to y, user added comment 'text') in ONE email in a callback method?

  • AJAX response not valid in C++ but Apache

    - by fehergeri
    I want to make a server written in C++ to power my game. I learned the basics of sockets and wrote a basic chat program that worked well. Now I want to create an HTTP server like Apache, but only for the AJAX request-response part. I think just for the beginning i copied one Apache response text, and i sent the exact response with the C++ server program. The problem that is that the browser (Firefox) connnects to the apache and everything works fine, except all of the requests get a correct response. But if i send this with the C++ client, then FireBug tells me that the response status is OK (200) but there is no actual response text. (How is this possible?) This response-text is exactly the same what apache sends. I made a bit-bit comparison and they were the same. The php file wich is the original response <?php echo "AS";echo rand(0,9); ?> And the origional source code: Socket.h http://pastebin.com/bW9qxtrR Socket.cpp http://pastebin.com/S3c8RFM7 main.cpp http://pastebin.com/ckExuXsR index.html http://pastebin.com/mcfEEqPP < this is the requester file. ajax.js http://pastebin.com/uXJe9hVC benchmark.js http://pastebin.com/djSYtKg9 jQuery is not needed. The main.cpp there is lot of trash code like main3 and main4 functions, these do not affect the result. I know that the response stuff in the C++ code is not really good because the connection closing is not the best; I will fix that later now I want to send a success response first. UPDATE: now i tested today a lot again and i find out there is no problem with the socket. I used the fiddler program to capture the the good answer and to capture the bad. They were the same. After this i turned off my socket application, and forced fiddler to auto respond, and the answer from the 'bad' answer still bat. So after that i replaced the bad with the good and nothing happedned. The bad answer with the good text still bad on the :8888 port but the other on the original :80 port was good, but they were absolutly the same and the same program sended it (fiddler) i think there is something missing if the response is not on the same server address (even not the same port). UPDATE: oh my god! i cant send ajax request to a remote server. now i know this.

Does apple give us information/user id's or email id's of poeple who have downloaded the app? Many thanks in advance for any help with this.. PB

  • Do I need to rebuild application after adding a new iPhone in ad hoc distribution?

    - by RaYell
    I'm using Ad Hoc distribution to send preview/beta version of my iPhone apps to customers for approval. I'm always sending a zipped application and mobileprovision files. Sometimes however I encountered situation when nothing in the application changed but we needed to add a new device for testing. I've added a device in Provisioning portal and assigned it to a provisioning profile my application uses for ad hoc distribution. I've downloaded new mobileprovision file and imported it to xcode now the question is do I need to rebuild the application to enable the app on a new device or would it be enough to just send old build with updated mobileprovision file?

    i will have the following set up: people will be sending text messages to a server, and that server will be forwarding the messages to other phone numbers i am not sure what kind of framework i should use. should i develop an SMS gateway and use AT commands? should i just try to somehow use AIM or GCHAT to capture and send SMS messages? would there be a different more suitable configuration? are there already developed frameworks that are free which i can use? for example i know that i can send an SMS to almost anyone through gchat or aim by sending a message to "+" and the number of the person. is this scalable and can i use it for my own benefit? any sms developers out there?
