In this article you will get to understand that how to resolve destination host unreachable issue in Linux.

What to do to resolve this destination Host unreachable?


To resolve this  issue we need to follow below simple steps.

Error: – icmp_seq=2 Destination Host Unreachable Issue


Cause: – When you are trying to ping Linux machine from one node to another node then you may face the issue “host unreachable”, the reason behind this issue is the selection of network while creation of Linux machine.


Solution: – To resolve this issue you need to select the proper network selection.


Example: – In this case, there are two machine prod and dr, When I was tried to ping dr machine from prod then I faced below issue. I checked so many things like firewalls, etc/hosts file entries and so on, but didn’t get resolution then, at last, I checked my network configuration and found it was set as NAT. I have changed the Network from NAT to the host-only adapter and then tried again finally, that issue has been resolved.


Before changing the network from NAT to Host-only adapter.
