One possible solution:
Simply store the information in a hash in a yaml file.
E.g. /home/user/.myapp.config could contain:

SERVER: news.example.org
PORT: 100
USER: myname
PASS: topsecret

Ruby code to load the settings:

require 'yaml'
CONFIG = YAML.load_file(File.join(ENV["HOME"], ".myapp.config"))
puts "Server: #{CONFIG["SERVER"]}"
puts "Server: #{CONFIG["PORT"]}"
...
