Well, as I feared, my 20+ years since dealing with HP-UX has put me deep into the Big Muddy. I'm afraid I have to consign you to the not-so-tender mercies of stack-overflow or a HP-UX SIG that might be out there.
I'm sure you have a compelling reason to do this on a speciality OS, but it's a lot easier on Ubuntu, especially if you have the option to install it as a virtual machine on your host.
As an alternative, consider EC2 instances of Ubuntu on AWS. It's something of its own Sisyphus learning curve, but you can set it up on web and ssh into it without having a VM on your HP-UX host. Unless, of course, Those Whose Lives as IT Professionals Would Be Bliss If It Were Not For Users, have shut you off from port 22.
As much as I'd love to be of some help, fakin' it 'til you make it at someone else's expense ain't the right thing to do. That said, if you need help puzzling out some more universal details, "I'm in town all week," said the comedian, and ping me @technocrat if I miss your question.
