users -> dansguardian -> squid -> internet problem.
i have many users on a closed network
and they surf through a redhat fire wall.
Linux version 2.6.9-1.667smp (email@example.com) (gcc
version 3.4.2 20041017 (Red Hat 3.4.2-6.fc3)) #1 SMP Tue Nov 2 14:59:52
the apache web engine has been running great for about a year.
the postmail has been running well for about a year or so.
a few bugs with cyrus, but working.
i have setup squid in transparent mode, and users can connect to the

squid logged every web site.
then i disabled the iptables rule and brought up dansguardian in the
dansguardian never connects to squid.
i turned on DEBUG in dansguardian and recompiled it.
it makes it through ConnectionHandler.cpp line 263. and attempts to do
with FDTunnel, where it makes it to line 183 where it attempts to do a
select( and then fails.
not sure what this is all about.
