hi there ,
I'm not familiar with linux firewall .
I tried to block port 6891 thru 6900 to disable msn messenger file
transfer.
following is the result of my linux ipchain -L :
Chain input (policy ACCEPT):
target prot opt source destination
ports
DENY tcp ------ anywhere anywhere
any -> 6891:6900
ACCEPT all ---f-- anywhere anywhere
n/
a
acctin all ------ anywhere anywhere

acctboth all ------ anywhere anywhere
n/

Chain forward (policy DENY):
target prot opt source destination
ports
DENY tcp ------ anywhere anywhere
any -> 6891:6900
ACCEPT all ---f-- anywhere anywhere
n/

where xxx.xxx.xxx.0 is my ip address.
can anyone help me to block port 6891 thru 6900?
I tried and tried , but it just won't work?
please show me the right rule to block these ports.
any message from you will be appreciated.
tks .

Maybe if you used a real news reader and a real news server, you wouldn't
have problems missing posts.
