C++ IP Address human-readable form
In C/C++, you can use the regular gethostbyname() call to turn a dotted-IP address string ("127.0.0.1" in the case of localhost) into a structure suitable for standard socket calls. Now how do you translate it back? I know I can do some bit-shifting to get exactly which bit sets I want and just print those out, but is there any "standa...

I am putting together a port scanner as a learning exercise. My problem is I'm trying to set the maximum segment size option(MSS) in the TCP header. I had a look at tcp.h, but I'm having trouble figuring out how to set it. I was hoping there would be an option like this: tcp_header->mss(32000); Something similar to the above was in tc...
Why won't TcpClient.Write throw an exception when writing to a closed connection (the first time)?
I have a simple program that uses TcpClient and SslStream to write data to a socket. To test it I ran the program over night so my program would open the connection, write nothing for a long time, so the firewall or remote server would close the connection. This morning I took a look at TCPView and verified the connection was closed ...

Wrapping BSD select() with JNA
I need to wrap a BSD-like C socket API to Java with JNA. It has basically the same functions as standard BSD socket API. Wrapping select() is problematic because of the fd_set-structure required in its arguments and the FD_* masking functions (macros) that are needed to handle fd_sets. I tried to crawl through the header files (e.g. sys...

setSoTimeout on a client socket doesn't affect the socket
I have a Java application with three threads that open, each, a socket and connect to a server on different ports. I set so_timeout on each of these sockets after the connection to the server is established. After that the threads block waiting on read(). Only one of the threads times out after 20 seconds (which is the timeout I set). Th...
