def check_channel_exec_request(self, channel, command):
return False<EOL>
Determine if a shell command will be executed for the client.  If this
method returns C{True}, the channel should be connected to the stdin,
stdout, and stderr of the shell command.

The default implementation always returns C{False}.

@param channel: the L{Channel} the request arrived on.
@type channel: L{Channel}
@param command: the command to execute.
@type command: str
@return: C{True} if this channel is now hooked up to the stdin,
    stdout, and stderr of the executing command; C{False} if the
    command will not be executed.
