Default Remotely Unlock Fully Encrypted Debian Squeeze

I followed the tutorial[1], but when I try and ssh to my server, I get a "Connection Refused" error.

I have tried changing the port in /etc/defaults/dropbear and allowing that port in ufw (22 is disabled). But nmap shows that at boot the new port is closed. In fact, all ports seem closed.

How can I make sure that a port is open so I can unlock the LUKS container?

once the initrd is booted, can you actually ping the server?

Yes: I can ping the server, but nmap shows all the ports as closed.

when you can ping it, it means the networking is up so the altered initrd works.... as for the port, no idea...

Setup an encrypted Squeeze in a vm, run the script and try if you can remotely unlock it - well, you can.... so you have something configured somewhere that prevents that. I can't help you with that.
