Problem with net-ssh

Ruby JRuby
1

I’m working with net-ssh 2.0.11 and jruby 1.3.0. When running this
simple script:

require ‘rubygems’
require ‘net/ssh’
Net::SSH.start(‘su-subdev01’, ‘wasuser’, :verbose => :debug) do |ssh|
output = ssh.exec!(“hostname && uptime”)
puts output
end

I get this error:

It doesn’t seem to matter what hostname I use.

I get this error:

Can you try with the latest JRuby (1.3.1) and jruby-openssl (0.5.1)?
Some bugs were recently fixed in this area.

Cheers,
