   |First, I'll set 2000 for the argument of 
   |Session#setServerAliveInterval(int milliseconds).
   |But I have a question.
   |Channel object can only detect the error of TCP/IP socket by this ?
   |Or TCP/IP socket can be protected from sudden server's disconnection?

In every 2000 millisoconds, the chunk of data will be sent to the remote
in the SSH protocol layer.  If there is no response from the remote, 
the JSch will disconnect the session and channels. 
In this case, Channel#isClosed() becomes "true".


Sincerely,
