But in between linux and HP-UX machine what? It was or wasn't working?
If this works between Linux systems, but just not to HP-UX, it may be the SSH you're using on HP-UX. Solaris used to be the same way, you could connect via SSH, but keyswaps didn't work. You had to remove the 'built-in' SSH server, and install OpenSSH, which worked flawlessly.
Are you using OpenSSH on HP-UX, or the default SSH that comes with it? You can try to install OpenSSH, and see if that works, chances are it will.
