How do I check and configure LAN properties? Once I'm by the installation process (Installing RedHat 7.3) , how do I check the configuration of the NIC?
netconfig will do it. just type `netconfig` at a command prompt. Also, why are you installing 7.3 instead of 8.0? Is there a good reason? If not, upgrade. It is free, come on.
ifconfig is also another way of viewing/changing your network options. Also route will display your routing table. iptables --list will show your current filtering/forwarding/nat chains in use.
Just using ifconfig and iptables doesn't make any persistant changes, though. Unless you're a little experienced, I recommend that you use the configuration tools, since they will update the configuration files as well as the runtime kernel parameters. That way, the changes will be persistant.
