If you can ping the board, there's definitely no problem at the mac/phy levels, so I don't think you need to include that.
Probably you have a wrong SSS code or made a mistake in tcp configuration: infact ping relies on UDP, while the server-client connection requires TCP which is a bit more complex.
Using a network analyzer like Wireshark can easily help you to find out if connection initiates and where it fails before being established.

I can send words or command via Telnet or Ping, when I use a router. However, I always failed when I directly connect the board and PC with a cross-over cable. I am really confused, I hope that you could help me.
Have a good day!
