Red Hat 7.3, running iptables.
Apache + bind setup for ad blocking.
This morning I discovered references to 'califia.imaginemedia.com'
splattered over various and sundry areas of my system.
'califia.imaginemedia.com' is one of the names resolving to
127.0.0.1 in my hosts file.
With no browsers or other net clients running, 'lsof -i'
shows (abbreviated for brevity):

('penguin' is the name of the local system. 'oh-lyndhurst4e-2-147.clvhoh.adelphia.net'
is the name assigned via dhcp)
Also, the apache access_log now includes lines like
califia.imaginemedia.com - - [19/Jul/2002:10:59:16 -0400] "GET /ad/N3064.Forbes.com/B1023165.8;sz=1x1;ord=2002.07.19.14.48.55? HTTP/1.1" 404 369
for blocked requests, where the source for the request used to be
'localhost.localdomain'. All the references in access_log seem otherwise
normal, in that they are blocked attempts to load ads from sites I
actually visited.
I'm not seeing any symptoms of problems, but I've shut down xinetd, named,
and http until I figure out what's going on here.
Any and all help is welcome.
