Problem with net-ssh

I’m getting the following error when I run the switchtower setup
command:

/usr/lib/ruby/gems/1.8/gems/net-ssh-1.0.3/lib/net/ssh/transport/packet-stream.rb:203:in

Any clue what’s up with that? I don’t know if it’s a problem with the
gem, with my client machine, or with my server.
