Subject: net-ssh: Trouble forwarding local ports to a remote server

Here's the plan: I need to forward a Samba connection on my machine to a
remote server.  When logging into the remote server, I should be able to
run smbclient -L \\localhost and see the Samba server from my machine.
Here's the script I'm running:

require 'net/ssh'

Net::SSH.start(hostname, user, :password => pass) do |sshConnection|
  sshConnection.forward.remote(445, 'localhost', 445)

  sshConnection.loop do
    sleep 0.5
    ! sshConnection.forward.active_remotes.include?([445, '127.0.0.1'])
  end

  puts 'Connection open'
  sleep 60
end

A chunk of this is just in there for testing, but within that 60-second
window, I should be able to log in to the remote server and run that
smbclient -L \\localhost command and see my shares, right?

Currently, it's not working.  Here's what I've found:
- ssh -R 445:localhost:445 user@hostname forwards fine and I can see the
shares (expected)
- If the script isn't running and I run smbclient, I get an error about
the server not running (expected)
- If the script is running and I run smbclient, it hangs until the 60
seconds are up (unexpected)

Any thoughts?
