What would be the best method for configuring OS X Network Proxy preferences in Objective C? If anyone has any code examples that would be very helpful. Also - I have been searching all around the interwebs and can't seem to find a good source for setting OS X System preferences/settings with Objective C. Anyone have any good source...
Hi all, I would like to know about the inbuilt library functions in C to build a complete packet(along with frame) and to send it over a network... Can any one upload the C code which does the above stuff... :) ...
I really like the message passing primitives that D implements. I have only seen examples of message passing within a program though. Is there support for distributing the messages over e.g. a network? ...
I'm using getaddrinfo to start a local server accepting connections only on the localhost: struct addrinfo *res; struct addrinfo hints = {0}; hints.ai_family = AF_UNSPEC; hints.ai_socktype = SOCK_STREAM; hints.ai_protocol = IPPROTO_TCP; getaddrinfo(NULL, portbuf, &hints, &res); This seems to work fine, giving me the IPv6 address ::1 w...
Scenario: 2 network devices, each on separate private LANs. The LANs are connected by public Internet. Device on network A is listening on a socket; network A firewall has NAT port forward setup for external access from network B's port range. Device on network B makes outgoing connection to network A to connect to the listen socket. ...
What libraries out there let you control the download speed of network requests (http in particular). I don't see anything built-in in urllib2 (nor in (Py)Qt which I intend on using). Can Twisted control bandwidth? If not, how can I control the read buffer size of urllib2 or Twisted? sleeping to suspend network operations isn't an optio...
Hi, I suddenly find myself wondering this question, is it possible in java to hijack a socket? say a server is listening on port 5000, would it be possible to write a java programme to listen on port 5000, and forward the same data to the server via port 5000. What would be involved in doing this? I feel this involves writing a new net...
Hi! I'm working on an app, in which server (windows based) will connect to the ipad application. Then data will be transfer from the server to the ipad app. I saw different apps like PDF Expert, Wifi HD, allows server apps to connect to the iphone app through IP address. I decided to use this approach. But I don't know how to implement t...
this piece of code is supposed to consider flows in both direction as one flow. for example: srcAddr,dstAddr,srcPort,dstPort 192.168.1.65, 217.174.16.1, 123456,80 should be the same as 217.174.16.1, 192.168.1.65,80,123456 Another Example: 192.168.1.65, 217.174.16.1, 12345, 80, TCP 217.174.16.1, 192.168.1.65, 80, 12345, TCP 192.168...
Are there any .net classes that allow for controlling an internet connection? Such as connecting/disconnecting from a wireless connection? Any details need to be useable in any .net framework version running on XP sp/3 or later windows OS. ...
Hi, I'm having trouble creating a port in Unix. This code keeps returning "Error creating socket (3)", which makes no sense whatsoever, since sockfd must be smaller than 0 to print the error line. server.c: int main (int argc, char **argv) { int sockfd; struct sockaddr_in server_sockaddr; char buff[TRANSFER_BUFFER_LEN]; /* che...
Hi, Can anybody provide me some sample example on Client and server connection using sockets in C++. I have gone through some tutorials now i want to implement it. How to start ? ...
I am trying to understand how are file descriptors related to sockets. As per my understanding, you listen on a particular file descriptor, once a connection comes in , you accept it , which returns you another file descriptor ( 2 in all ) and you use this 2nd descriptor to send/recv data. The strange behaviour i am observing is that a...
How can I enumerate all machine names and IPs of remote computers in the local network ? Note: NOT on Windows (how to do that one finds via google), I need something that works on Linux ! Or a C/C++ sample would also do it, I can call libc from C#. ...

Hi, I'm building a system for monitoring several large web sites (resources), using distributed web services controlled by a central controller. I'm coming to a specific part of the design - the actual reporting of resources that are thought to have fallen over. My problem is that there is always the chance that the actual monitor it...
We are building an iPhone chat application. When sending from the browser to the iPhone a JSON chat message: {"content":"Hi"} The iPhone receives: {"content":{"0":72,"1":105,"length":2}} But, we intend for it to receive the same exact message. To reproduce this issue, first install node.js & redis. Then: Get the code: ...
I am able to get the current ip address of my device/machine that I am using - by using this question's answer. I have gone through this question. Java allows to get the IPAddress from a domain name. Is it possible in objective c ? How ? The second question is How to get the name of device/machine by using it's IPAddress. Say for examp...
