Is your fog server connected directly to the internet? You understand linux and the command line?
The way to obtain your systems IP (which you should have setup statically) is to run:
ifconfig
If you have multiple interfaces, you’ll need to figure out which interface you’re trying to use and use the IP associated with that.
I assume your IP is going to be in the range of 192.168.1.2 thru 192.168.1.254 as you put your router and dns server as 192.168.1.1
Your files to be edited should be located in:
<locationOfFogInstallFolder>/lib/redhat
There are two files in there which I forget the names of.
However, if my memory serves me correctly, when you do the install, it should ask you what you want to set your IP up as, and it defaults to your systems IP, so unless your FOG server is directly connected to the Modem, it should have a private IP address assigned to it already. I’d recommend, until you understand what this software is doing, sticking with the defaults.
