] How would I change the password for the client-ID on a freebsd box where
] DCC was built from ports?

] How would I go about doing this?

It would be easiest to 
  1. copy the /var/dcc/ids from your existing DCC servers to your
      new DCC servers.  Ensure that /var/dcc/ids is identical on all
      of your servers.  (or /etc/dcc/ids or wherever you put the DCC
      home directory)

  2. create a new DNS name like with the IP addresses of
     all 4 of your DCC servers.

  3. Run this command on each DCC client:
        cdcc "add   RTT-1000 ms  32768 secret"
      were 32768 is a client ID with password SECRET in /var/dcc/ids on all
      of your servers.

Then your DCC clients will load balance themselves among your servers.
Each client will prefer the currently nearest/fastest server.
Each clients monitors the round trip time (RTT) to all know servers.
