Hey, I'm a newcomer to using C++ but have got a general Idea of its syntax and useability. I want to learn how to communicate over networks through C++ programming though but I can't seem to find any tutorials for C++ specifically. Does anyone know any good resources to learn about networking with C++ or what I should start with? Thanks...
Hi, I need some help with finding network interfaces based on a provided IP address. I need a cross-platform way to reliably find the local interface that has the given address in both IPv4 and IPv6 formats. I created the attached program to take an IP address as a string and search through the results of getifaddrs. The reason is th...

I have some existing C code that uses ICMP raw sockets to do Ping and I need to use this code in Java as Java does not support ICMP packages. When I wrap the code in JNI and call it, the C code fails to obtain the socket when doing: socket(AF_INET, SOCK_RAW, 1); I guess that Java has dropped some privileges that disables the use of raw...
I'm trying to figure out how make a basic GET request using Network.HTTP.simpleHTTP that will use a proxy. I have tried setting the http_proxy environment variable, and I think I understand how to make a Proxy using Network.HTTP.Proxy. But there seems to be nothing in the API on Hackage for how to set a simpleHTTP call or Request type ...
I am well aware that employers monitor content and activity of their employees; I was just wondering though if its possible to know when someone has remotely connected to your pc or is monitoring your pc virtually. I tried looking at the task manager but its hard to determine which process this is and of course it does not have to be in ...
I'm writing a client for a binary socket protocol in PHP, and it's a pain. I'm currently using pack to convert numbers into binary strings, but it's lacking. Two options pack has are: Write a signed 32 bit integer in machine byte order Write an insigned 32 bit integer in big endian byte order But I need to write signed 32 bit integer...
I'm reading 8 bytes from a socket in PHP, and want to transform them into a 64 bit signed integer. How can I do this in 64 bit PHP? unpack doesn't support 64 bit numbers In 32 bit PHP, is there a way to make it into a string that can be used by BCMath? ...
Can anyone explain how an XMPP server pushes data to an XMPP client? This client will most likely be behind a firewall and will not have its own IP on the Internet so how can the client be notified? Does the client leave a connection open with the server at all times? ...
I'm writing a Java server which uses plain sockets to accept connections from clients. I'm using the fairly simple model where each connection has its own thread reading from it in blocking mode. Pseudo code: handshake(); while(!closed) { length = readHeader(); // this usually blocks a few seconds readMessage(length); } cleanup();...
I am doing research about network traffic characterization. While processing collected data (captured by tcpdump and saved to a database), I stumbled over the weird phenomenon with packet (or flow) inter-arrival times: Inter-arrival times of 35-170µsec are never observed Of course, without a DAG card (which would do hardware time stamp...
Hi, I have a program that does different things my questions is related to access files in a network mapped drive or a shared folder the program can run a file msi/exe from the network (network mapped drive or a shared folder) the program can copy file from the network (network mapped drive or a shared folder) how I can check if the f...
I have a server, and Client that are working fine, they transfer file to each other and handle commands with success. The thing is that once connected to the server, the server can ask the Client to update itself. Since I did everything using sockets with a TCP connection, and I am NOT able to use java web start, I am looking for a way ...
These questions relate to the basics of networking, but I have not found an answer yet! Question 1: Can a 100Mbps switch handle 2 simultaneous TCP streams running at 100Mbps? To illustrate this if you have 4 PC's on 1 switch (100Mbps with no other connections) and you had two separate streams, what speed would they reach? Would one stre...
I am writing a C library which involves telling other computers on the subnet to send me messages. Therefore I must announce to them my IP address. This library should work on Linux, OS X and Windows. Currently I'm thinking mostly about the POSIX layer. Given that a computer can have more than one address (for example if it has more ...
