I use OpenBSD as my "router and firewall" It uses PF for the firewall. This is where the "work to share the connection" is done. With PF I can control all of the internet traffic in and out. This statement will block and drop traffic and is in the pf.cong file.
#block caching century block drop quick from xxx.xxx.xxx.0/24 block drop quick to xxx.xxx.xxx.0/24
replace the "xxx" with ip addresses and the /24 makes it class C subnet
Sorry I wasn't more clear...how do you find the addresses of the servers in order to block them? I can't figure out how to find them. -- The goal of the broadcast engineer is to get all the meters on the transmitter to go as far to the right as possible!!
I use a program call "trafshow" for regular traffic viewing. When I need to be sure I use "tcpdump" to record the traffic so I can look at it in detail. Both are run on linux or unix.
