I'm trying to set up a new box with CentOS7.2. I have an existing box already running (now up to 7.3) on the same subnet, although in a different physical room in my building (existing box is in a "server room"), and the new box is sitting on my desk, connected to a switch that my laptop is also connected to.
My laptop has no trouble reaching the network.
I've configured a static ip and fqhn on the new box. The output from "ip addr" reflects this.
On the first box, in "/etc/sysconfig/network-scripts", I have "ifcfg-eno1" configured with my static ip, gateway ip, and other flags. This appears to work fine.
On the new box, I found "ifcfg-enp0s31f6" in "/etc/sysconfig". I added my static ip and the same gateway ip as the first box.
I've rebooted the new box, to be sure.
However, when all this is done, it doesn't seem like it's getting to the network. I can't ping the gateway IP or the other box that I set up, or any other IP that I've tried. They all say "Destination Host Unreachable".
What else might I be doing wrong?
