Yes, it was registered before.

Nope. But when I register the node it is not listed anywhere, e.g.

$ sudo euca_conf --register-nodes 192.168.1.106

INFO: We expect all nodes to have eucalyptus installed
in //var/lib/eucalyptus/keys for key synchronization.

sudo euca_conf --deregister-nodes 192.168.1.106
[sudo] password for ubuntu:

ubuntu@frontend:~$ cd /etc/eucalyptus/

I added it manually to eucalyptus.conf in the past, will remove it.

I will do so, first reinstall the CC, then the NC and report back if the
situation changes.
