Don't think so, the term's doesn't sound familiar.

So, remove about six tabs at the start of the file... It only needs
white space between some parameters, it doesn't *need* several of
them. ;-)

I don't do a great deal of web browsing, so I've only bothered to stick
a few common annoyances into my DNS server. Some of them are very old,
I don't know if they still exist.
This is in the named.conf file:
## advert blocking:
zone "adimages.com" { type master; file "dead.zone"; };
zone "admonitor.com" { type master; file "dead.zone"; };
zone "adsfac.net" { type master; file "dead.zone"; };
zone "advertising.com" { type master; file "dead.zone"; };
zone "amazingmedia.com" { type master; file "dead.zone"; };
zone "casalemedia.com" { type master; file "dead.zone"; };
zone "clickagents.com" { type master; file "dead.zone"; };
zone "commission-junction.com" { type master; file "dead.zone"; };
zone "doubleclick.net" { type master; file "dead.zone"; };
zone "doubleclick.com" { type master; file "dead.zone"; };
zone "adwords.google.com" { type master; file "dead.zone"; };
zone "googlesyndication.com" { type master; file "dead.zone"; };
zone "fastclick.net" { type master; file "dead.zone"; };
zone "infospace.com" { type master; file "dead.zone"; };
zone "mediaplex.com" { type master; file "dead.zone"; };
zone "msads.com" { type master; file "dead.zone"; };
zone "ads.optusnet.com.au" { type master; file "dead.zone"; };
zone "qksrv.net" { type master; file "dead.zone"; };
zone "ads.x10.com" { type master; file "dead.zone"; };
zone "adserver.yahoo.com" { type master; file "dead.zone"; };
#zone "yimg.com" { type master; file "dead.zone"; };
And this is the dead.zone file:
$TTL 86400
@ IN SOA ns.localdomain. hostmaster.mail.localdomain. (
200 ; serial
28800 ; refresh
7200 ; retry
604800 ; expire
86400 ; ttl
)
IN NS ns.localdomain.
Yep, that's the whole thing (9 or 10 lines worth, if you want to get rid
of a carriage return). Look-ups for any of the above domains, or
sub-domains of them, result in an instant "no answer" answer. This one
DNS server does the job for all the PCs on the network.

Test running FC6 & FC5, and still using FC4.
I delete all private mail, unseen. I read from the list.
