In order to update /etc/services and /etc/inetd.conf, run

   /usr/local/libexec/amanda/patch-system --disable-index --disable-tape

You should check both of these files, verifying proper installation.
Once verified issue the command:

   kill -HUP `cat /var/run/inetd.pid`

You also need to create /operator/.amandahosts, which will contain
the FQDN of the tape server.  The contents should look like this:

   backup.openbsd.org amanda

The permissions of /operator/.amandahosts must be restricted:

   chmod u=rw /operator/.amandahosts
   chown operator:operator /operator/.amandahosts
