Thanks, Henrik. My iptables does allow all loopback traffics, but it
doesn't show any improvement, even when I disable the firewall
completely. squidguard gives the same error as well.

It seems that the reason is selinux on FC4. I disabled selinux on my
FC4 box by modifying the /etc/sysconfig/selinux file, and both
ncsa_auth and squidguard run well. However, disable selinux makes
iptables stops forwarding packages between the two ethernet
interfaces. Enable selinux again doesn't restore the box to its
original state. I have to rebuild the box.
