Capistrano SSH::AuthenticationFailed, not prompting for password

I've been using capistrano successfully for a while now and all of a sudden in every project I've lost the ability to deploy.

Environment:

  • os X (Mavericks)
  • ruby 1.9.3p194
  • rvm (locally, not on server)
  • rails 3.2 and up
  • RubyGems 1.8.25

I'm not using rsa_keys or anything I want capistrano to prompt for user and password. Suddenly it has decided not to ask for a password, but does ask for user. Then it rolls back and gives me the following error.

[deploy:update_code] exception while rolling back: Capistrano::ConnectionError, connection failed for: sub.example.com (Net::SSH::AuthenticationFailed: Authentication failed for user [email protected])
connection failed for: sub.example.com (Net::SSH::AuthenticationFailed: Authentication failed for user [email protected])

This has occurred on my personal laptop and my iMac at work. It occurs when deploying to two different servers (both linux)

I'm completely at a loss here. Any ideas?

Figured it out! Apparently this issue was with net-ssh gem. I had version 2.8.0 installed recently with some updates to my development environment and was the cause.

I'm not sure why it was failing, but gem uninstall net-ssh -v 2.8.0< fixed it for me.

If anyone actually knows why this was an issue or how I can correct this issue with the newer version of net-ssh I'd be interested to hear it.
