Hi list:

Using MSVCPP C++ 9.0 and Boost_1_43_0, and trying to follow the examples in
the tutorial.

The Daytime.4 example hangs in line

size_t len = socket.receive_from(boost::asio::buffer(recv_buf),
sender_endpoint);

it seem that wait indefinitely for a response.

Using this server:

char* serverName = "ntp-nist.ldsbc.edu";    // 198.60.73.8  LDSBC, Salt Lake
City, Utah

Neither with:
char* serverName = "time-nw.nist.gov" or any other in the
http://tf.nist.gov/tf-cgi/servers.cgi#  list.

By the way, the Daytime.1 (asynchronous TCP datytime client) example and
Timer1 to 5 examples works fine for me.

Any suggestion would be appreciated.

Thanks

A.J.Millan
