I'll try this when I get home tonight.  I'll check the
/etc/defaults/rc.conf to see that I didn't muck it up, but I'm pretty
sure I heeded the advice to make local changes in /etc/rc.conf.  I've
put a fake domain in my hosts file, didn't make any difference.  When I
had my cvsup problem, had to make sure that my hosts file had
"127.0.0.1	localhost freebsd" in it, and I think the order was
important, too.
As you can see, this has always been flaky for me.  How would I make
sure the hosts file gets re-read by the system (besides rebooting)? 
Maybe I haven't been consistent in this respect.

thanks for the help
Kevin
