I believe the shutdown sequence is as follows (as described here): The MSDN documentation (remarks section) reads: When using a connection-oriented Socket, always call the Shutdown method bef...

I'm trying to code an agnostic echo server, that could accept both IPv4 and IPv6 connection. I'm working with addrinfo structure, set with getaddrinfo. Ipv4 connect has no problem while I can't get...

Recently I was working with the Berkeley socket API for IPv6, and noticed that IPv6 addresses (sockaddr_in6) have a field called sin6_scope_id, which was not part of IPv4 addresses. After searchin...

For the following I'm assuming one network card. I have a component of my program which is designed to let others in the subnet know of its existence. For this, I've implemented a solution where ...

I am trying to write a web server that listens on both IPv4 and IPv6 addresses. However, the code that I originally wrote did not work. Then I found out that the IPv6 structures work for both IPv4 ...

I've got code that looks something like this, where addr is a sockaddr*: struct sockaddr_in *sin = (struct sockaddr_in *) addr; const char *IP=inet_ntoa(sin -> sin_addr); I believe this is ve...

I have read the documentation at least 10 times now and have also read some 10 or so code snippets and full programs where non-blocking sockets are used for sending data. The problem is that some o...

The constant INADDR_ANY is the so-called IPv4 wildcard address. The wildcard IP address is useful for applications that bind Internet domain sockets on multihomed hosts. If an application on a mul...

If I have a socket file descriptor connected (either by connect or by bind), type SOCK_STREAM, is it possible to get the remote address / IP address? I need to do this within a function where I do...

I am using berkeley sockets and TCP (SOCK_STREAM sockets). The process is: I connect to a remote address. I send a message to it. I receive a message from it. Imagine I am using the following ...

I want to account for a possible scenario where clients of my TCP/IP stream socket service send data to my service faster than it manages to move the data to its buffers (I am talking about applica...

I'm working my way through UNIX Network Programming Volume 1 by Richard Stevens and attempting to write a TCP Echo Client that uses the Telnet protocol. I'm still in the early stages and attempting...
