thank you for your help.
well I did harp in host OS of the two guest virtual machine (the two scientific linux).
It seem that they are indeed detected.
Because I see their name.
Now since I want to learn the nmap and linux networking, can you guide me how can I find what block the ping in the scientif linux machine.
Since it is VM in my computer I have direct access to it.
What should I do to detect what is blocking the ping?
Is it the iptables or something else?
I am newbie to this issue so any help will be welcome.
