Don't forget that you've got to do the same thing to at
least /opt/ltsp/i86/etc/lts.conf, not just /etc/hosts.  Also, you've got
to tweak the stuff under /etc/sysconfig/.  This is typically why I
choose something like 172.16.31.0/24 or 192.168.254.0/24 from the get-
go; very few people seem to think of using those ranges.  :-)
