Net::SSH is unable to use my RSA Key

[Marco Schroeder]

Hi all,

I'm currently using ruby 1.9.1p429 and net-ssh-2.0.23

When I try to use Net:SSH with the following example:
#!/usr/bin/env ruby
require 'net/ssh'
Net::SSH.start('examplehost', 'user', assword => "passwordtest") do
|ssh|
output = ssh.exec!("whoami")
puts output
end

it always throws me the following exception:
/usr/lib/ruby/gems/1.9/gems/net-ssh-2.0.23/lib/net/ssh/key_factory.rb:62:in
`initialize': Neither PUB key nor PRIV key:: nested asn1 error

When I delete my id_rsa Key it asks me for password authentication and
then it works. But unfortunately not which pubkey authentication.

As far as I remember, in the past with ruby 1.8.6 that worked already.

Any hints would be appreciated.

Thanks,
Marco
