Hello,

I'm using synchronous TCP communication via asio sockets. I have following problems:

First problem;  When I unplug ethernet cable, "eth0: Link is Down" is written in the console, but socket.write_some command does not detect link down failure.

Second problem; During socket.connect command, if I plug ethernet cable, connect command does not detect this till "Connection timed out" error occurs. If I run socket.connect again, it detects the connection.

How can I detect these plug/unplug events as soon as the event occurs?

Best Regards,
