Hi there... got one newbie question here. Just wondering how can i block yahoo messenger port using IP tables in my box. Clients using YM is behind this box.  YM is using all possible ports even port 80.

TIA

just block all the connection to yahoo msg server:

scs-fooa.yahoo.com
scs-foob.yahoo.com
scs-fooc.yahoo.com
scs-food.yahoo.com
scs-fooe.yahoo.com
scs-foof.yahoo.com

that is the list I got so far,  I am rejecting the connection to those
servers after my DNS chain rules so when we put the servers name instead of
ip address, it can resolve all the ip address to that server.

if you just want to block certain range of ip from the LAN, check the lates
patch-o-matic for iptables.

try blocking a certain destination..

ie i use scs.yahoo.com to connect to yahoo messenger,
there may be more out there, but just drop any packets
that may be trying to goto that destination.

IIRC I collected this data from two different locations, honestly can't
attribute proper credit now.
