Ridiculous newbie question

["Trustin Lee (이희승)"]

First off, you did not log the exception but just closed the connection
in exceptionCaught().

Perhaps the exception is about ClassCastException or
IllegalArgumentException which means you are sending unsupported message
type.  You'll have to add proper encoder/decoder to the pipeline in this
case.  Please refer to the Telnet example.
