I isolated Capistrano from the environment by creating a simple
Net::SSH script that makes one call via ssh:
#! /usr/local/bin/ruby
require 'rubygems'
require 'net/ssh'
Net::SSH.start('host1', 'tools') do |ssh|
output = ssh.exec!("hostname")
puts output
end
This is where all the issues lie, as I get exactly the same error.
Still digging...
