Subject: Re: Net::SSH Data Stream Problem

I had the same problem where my ssh connection closing early.  I solved
it by opening a shell- don't know if that can help with sftp though.  I
am having no problems copying files with the ftp library.

Net::SSH.start(SSH_SERVER, :username => u, :password => p) do |session|
  shell = session.shell.sync
  shell.exec( cmd ).stdout
end
