I am looking for a network tools on my PC to monitor
all connections at all times, so that I can kill conection which i
do not want and to see IP address which the chat software ( ie msn,
skype) connecting to my PC.
mb u can elaborate? what u mean by connections?
Use a firewall to see inbound outbound traffic and can disable a
connection if u want to.
To see ip addresses of connections
run>cmd>netstat -a
or download a free network analyzer tool such as wireshark
