Description
Create a Setup so that you can ping google but not able to ping Facebook from same system.
Pre-Requisites
- You should know the concept of Routing Table before doing this task.
- You should also know some basic commands.
Steps
- Let’s check that if our system can ping to both facebook & google.
So as you can see, for now we can ping to facebook & google.
- Now let’s check the default routing tables.
Here you can see a route table with destination 0.0.0.0 which allow all. So first we have to delete this routing table.
- For deleting routing table we use
route del
command.
- Now let’s check the connectivity.
So here we can see connectivity to both are unreachable.
- Now we will add a routing table with google.com IP.
You can found the google IP mapping using nslookup
command. To check gateway IP use cat /etc/resolv.conf
command.
- Finally let’s check the connectivity.
So here you can see that our system can google.com but facebook,com is unreachable.
Fin.
