These addresses are also compared against the configuration in the server CellServDB to make sure that we are actually configured as a ubik server for the current cell. The test suite uses the same logic as ubik to work out the addresses to put in the test CellServDB.

Putting the real IP in /etc/hosts made most things work. I'll have to
