I'm installing CentOS server on virtual box to test it out. I have little sysadmin and networking knowledge, so please elaborate as much as you can.
I'm following this tutorial, and I'm stuck on the following 2 steps (IP and DNS stuff). See the images, sorry couldn't insert images, the system wouldn't let me.
The tutorial uses
IP 192.168.1.1 for the server. I checked my router and checked the next available IP address which was
192.168.1.51 I then entered
255.255.255.0 as the submask without knowing why.
My next (and main) problem now is the
Primary DNS, and
Secondary DNSin image 11:
How do I decide what to put there? What if I put random IPs (as they appear to have done in this tutorial) and it pings that real IP or something similar.
Anyone can help me understand this better?
