    copied!<p>Im following the tutorials at the boost official web site <a href="http://www.boost.org/doc/libs/1_55_0/doc/html/boost_asio/tutorial/tutdaytime1.html" rel="nofollow">http://www.boost.org/doc/libs/1_55_0/doc/html/boost_asio/tutorial/tutdaytime1.html</a>.</p> <p>The program is working perfectly if i connect to "localhost" or "127.0.0.1" on the same machine. But if i run the client on another computer with the same network it fails to connect to the server. Why is this happening? and what would i have to do to get the client to run on another network?</p> <p>Error: connect: No connection could be made because the target machine actively refused it.</p> <p>Client:</p> <pre><code>#include &lt;iostream&gt; #include &lt;boost/array.hpp&gt; #include &lt;boost/asio.hpp&gt; using boost::asio::ip::tcp; int main() { try { boost::asio::io_service io_service; tcp::resolver resolver(io_service); char* serverName = "localhost"; tcp::resolver::query query(serverName, "daytime"); tcp::resolver::iterator endpoint_iterator = resolver.resolve(query); tcp::socket socket(io_service); while(true) { boost::asio::connect(socket, endpoint_iterator); for (;;) { boost::array&lt;char, 128&gt; buf; boost::system::error_code error; size_t len = socket.read_some(boost::asio::buffer(buf), error); if (error == boost::asio::error::eof) break; // Connection closed cleanly by peer. else if (error) throw boost::system::system_error(error); // Some other error. std::cout.write(buf.data(), len); std::cout &lt;&lt;"\n"; } } } catch (std::exception&amp; e) { std::cerr &lt;&lt; e.what() &lt;&lt; std::endl; } return 0; } </code></pre> <p>Server:</p> <pre><code>#include &lt;iostream&gt; #include &lt;string&gt; #include &lt;boost/asio.hpp&gt; using boost::asio::ip::tcp; int main() { try { boost::asio::io_service io_service; tcp::acceptor acceptor(io_service, tcp::endpoint(tcp::v4(), 13)); for (;;) { tcp::socket socket(io_service); acceptor.accept(socket); std::string message = "This is the Server!"; boost::system::error_code ignored_error; boost::asio::write(socket, boost::asio::buffer(message), ignored_error); } } catch (std::exception&amp; e) { std::cerr &lt;&lt; e.what() &lt;&lt; std::endl; } return 0; } </code></pre>
