Method: Net::SSH::Connection::Channel#do_request

Defined in:
lib/net/ssh/connection/channel.rb

#do_request(request, want_reply, data) ⇒ Object

Invoked when the server sends a channel request. If any #on_request callback has been registered for the specific type of this request, it is invoked. If want_reply is true, a packet will be sent of either CHANNEL_SUCCESS or CHANNEL_FAILURE type. If there was no callback to handle the request, CHANNEL_FAILURE will be sent. Otherwise, CHANNEL_SUCCESS, unless the callback raised ChannelRequestFailed. The callback should accept the channel as the first argument, and the request-specific data as the second.
