Hello, My windows mobile application (written in C# with the compact framework) needs to know if a particular machine is active or not. To achieve this goal, I thought to use a ping mechanism. I tried to use the Ping class implemented in the opennetcf framework (the System.Net.NetworkInformation.Ping class for the .NET Framework is no...
Is there any limit on the size of data that can be received by TCP client. With TCP socket communication, server is sending more data but the client is only getting 4K and stopping. ...
I have a simple problem which I'm sure someone here has done before... I want to rewrite Layer 4 TCP/IP streams (Not lower layer individual packets or frames.) Ettercap's etterfilter command lets you perform simple live replacements of Layer 4 TCP/IP streams based on fixed strings or regexes. Example ettercap scripting code: if (ip.p...
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\nC...
I am Trying to create AdHoc connection and for this i am using AdHoc wifi Interface provided by Microsoft. I have written code :- IDot11AdHocManager *pIAdHocMng = NULL ; HRESULT hr = CoInitialize(NULL); hr = CoCreateInstance(CLSID_Dot11AdHocManager,NULL,CLSCTX_INPROC_HANDLER ,IID_IDot11AdHocManager ,(void**)pIAdHocMng); if(hr == ...
For a user in active directory, the properties hold values for lastlogontime & lastlogontimestamp but the logoncount is 0. I am having only one domain controller in that domain. I found from surfing, that logonCount value of 0 indicates that the value is unknown. But I am totally confused with why it is unknown. Is that an issue with A...
I have a simple program to check if a port is open, but I want to shorten the timeout length on the socket connection because the default is far too long. I'm not sure how to do this though. Here's the code: #include <sys/socket.h> #include <sys/time.h> #include <sys/types.h> #include <arpa/inet.h> #include <netinet/in.h> #include <errn...
Hi, I have a program that uses gethostbyname (in Windows) in order to convert IP address to hostname. But, it works only for IPv4... What is the correct replacement for IPv6? Thanks. ...
Hi I have been looking for the answer to this question for some time. I am doing network programming for the iPhone and it is necessary for me to use the IP address of the device. This isn't a problem on the physical device as it has its own IP address on the network. However I was wondering what was the case with it on the simulator. D...
When I ping one site it returns "Request timed out". I want to make little program that will inform me (sound beep or something like that) when this server is online again. No matter in which language. I think it should be very simple script with a several lines of code. So how to write it? ...
Oh how I wish TCP was packet-based like UDP is! [see comments] But alas, that's not the case, so I'm trying to implement my own packet layer. Here's the chain of events so far (ignoring writing packets) Oh, and my Packets are very simply structured: two unsigned bytes for length, and then byte[length] data. (I can't imagine if they were...
I have received a job at a hospital which still uses COBOL for all organizational work, the whole (now 20 Terabyte) database (Which was a homebrew in, guess what, COBOL) is filled with the data of every patient since the last 45 (or so) years. So that was my story. Now to my question: Currently, all sockets were (from what I've seen) i...
If we can't decode the MD5 hash string, then what is the purpose of MD5 where can we use MD5. ...
What's an efficient method (preferably simple as well) for communicating with a remote server and allowing the user to 'interact' with it (IE submit commands, user interface) via the web browser (IE a text box to input commands, and an text area for output, or various command-less abstracted interfaces)? I have the 'standalone' python c...
Hi, I want to capture a RTSP stream from a camera into a series of fixed sized file 1MB each. and then send it to a storage server via Http POST. How do i do this. Target languages - any, prefer: JAVA. ...
I'm looking for a programmatic interface to the Solaris ifconfig(1M) command. Apparently Linux has the getifaddrs(3) command, but as far as I can tell this has not been ported to Solaris. Short of attempting to use the code at the link above, is there any way to determine ifconfig(1M)-type data (network interface presence, state, etc.)...
I want to be able to send files from an iPhone app to a computer. What would be the easiest way of doing this? I've made simple server client programs before, but in those, the client has always needed to connect to the server before being able to receive messages from it. There is an app for the iPhone called iSimulate, where you put a...
Hey guys I am looking for a good solid introduction book to the fundementals of network programming in C#. For example is have looked at this one http://www.amazon.com/C-Network-Programming-Richard-Blum/dp/0782141765/ref=pd_sim_b_5 but it is quite old now. Anyone used one recently, i would greatly appriciate it thanks dan ...
