...is a pain
I've been trying to filter out the doubleclick adverts,
though they seem to have some length to prevent you doing
this.
Adverts link to hostnames like ad.doubleclick.net or
m.doubleclick.net. Variations on these exist.
Trying to filter using the hostname to block outgoing
access can be done, though doubleclick names return
a different ip each time, so you'd have to run the firewall
script every couple of seconds.
The old ipchains howto listed some of doubleclick's ports.
Unless I can find a list, I'll just have to build one up from
the logs.
