I guess it is a bug in somewhere I do not know. ping and telnet work well
under such circumstance.
However, rsh, rcp, rlogin etc. do NOT work if DNS is not reachable. It may be
the rexec() 's problem. I am sure they tried to talk to DNS even though my
/etc/host.conf is correct. The tcpdump shows that these program try to talk
to DNS regardless the /etc/hosts and /etc/host.conf. So, I changed the Subject.
