You can run iptables -n -L and verify open port or services.
Code:
iptables -n -L iptables -n -L | less iptables -n -L | grep '80' iptables -n -L | grep '202.54.1.2' For TCPwrappers take a look at /etc/hosts.allow and /etc/hosts.deny file.

Hay forgot to mention from where to see?
I want this info if we are in network/internet to access that system..
In that case how we can find which tool(iptables/tcpwrappers) is used to block particular service?

Did you run command I gave you? Those are two methods that will tell if port or IP blocked using iptables or tcpwrappers.

Explain more
So am I understanding this correct? You want to be able to tell which service, be it iptables, or tcp wrappers is blocking your connection to a remote server?
What are you using this info for? -Rob
