Thanks for all the quick responses.  I got OpenDNS set up and working.

Just a mild curiosity.  I changed the DNS settings for the server, and
in the DHCP conf file (/etc/ltsp/dhcpd.conf), but users could still go
to playboy.  Digs on the server for playboy returned the OpenDNS IPs.
I also restarted networking, same result.

Once I rebooted the box, all worked as expected.  Is this a product of
other users having open Firefox sessions, or did I forget to do
something that rebooting fixed?
