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 ``True``, the channel should be connected to the stdin,
stdout, and stderr of the shell command.

The default implementation always returns ``False``.

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