TCP/IP applications by example

In this tutorial we'll implement some simple TCP/IP applications with ncat, bash and some other standard UNIX tools. The principles learned here can be used to implement networking applications in other languages.

The $ or # in front of command line examples denotes the system prompt. Do not type it

how to compile

$ gcc -g -Wall -I /path/to/libuv/include /path/to/libuv/uv.a -framework CoreServices server.c -o server
$ gcc -g -Wall -I /path/to/libuv/include /path/to/libuv/uv.a -framework CoreServices client.c -o client

	# Lets say we want to add a library and an executable, both with the same name.
	# In this example, it is resman

	add_library(resman ${src_cpps} ${src_hpps} )
	target_link_libraries(resman ${Boost_LIBRARIES} ${LIBYAML} ${LIBFMT})
	#
	# Add resman executable
	#
	# We call the executable resman-bin
	add_executable(resman-bin main.cpp )

	#include <iostream>
	#include <string>
	#include <curl/curl.h>


	static size_t WriteCallback(void contents, size_t size, size_t nmemb, void userp)
	{
	((std::string)userp)->append((char)contents, size * nmemb);
	return size * nmemb;
