= Net::SSH::ChannelRequestFailed < Net::SSH::Exception

(from /home/chedong/.local/share/rdoc)
------------------------------------------------------------------------
This exception is primarily used internally, but if you have a channel
request handler (see Net::SSH::Connection::Channel#on_request) that you
want to fail in such a way that the server knows it failed, you can
raise this exception in the handler and Net::SSH will translate that
into a "channel failure" message.
