Q. I have Debian Linux server in remote data center. I can ping server by its IP but not by hostname such as server.domain.com. How do I ping server by hostname?

A. This is client side DNS problem. All you have to do is setup correct DNS server:

=> Linux DNS Client Configuration

=> Solaris DNS Client Configuration
