This will attempt to connect to the passed host and port. The connection will be made in non-blocking mode, so if there is no route to the host, then it won't hold up capsd or the poller. Once a connection is made, the channel is returned to blocking mode.

Parameters:

host - remote host

port - port

timeout - timeout (ms)

Returns:

SocketChannel object already connected to the remote host/port pair.

Throws:

java.io.IOException

java.lang.InterruptedException
