Has any one successfully installed on a DNS-321

Has anyone successfully installed Serviio on a DNS-321? Not a DNS-320 or DNS-323. If so then please give details such as what package and versions used and steps used. I have tried numerous time to install the debian squeeze .061 package. The server doesn't start and the SSH login locks up with "Server refused to allocate pty" and stdin: is not a tty. I have tried this several time over the year and given up each time.
Thanks
Brian
