Capistrano remote authentication problem

Question

I'm trying to deploy to a slicehost slice using this config/deploy/production.rb file. I'm clueless & haven't used capistrano before now. Here are the steps I followed. Sorry but I'm completely new to capistrano. It keeps asking for my password (have set up passwordless SSH), and throwing this error:

(SocketError: getaddrinfo: Name or service not known)
connection failed for: ---------.com (Net::SSH::AuthenticationFailed: -----)

First, it's a 'bort' app http://github.com/fudgestudios/bort/tree/master

Second, I used the ubuntu-machine gem, detailed here:

Answer 1

I think the problem would be either

• It can't resolve your hostname
• You typo wrong domain value

Just in case, have you tried to set the domain value to be your server's IP address instead?
