i'm new here , trying to find my way in this new world for me.
i'v been playing a little with iphone security and network usage and want to know more about the processes that connect to the internet.
is there a manual for netstat ? can someone share how to see a process connections in SSH console?

also i have the firewall IP which i purchased but it does not block all traffic only applications so services still connect to the internet at free will . is there something that can help me to block any traffic according to rules , for example *.domain.com will be blocked?

thanks and sorry for the long questions
