Hello,
I have some questions about networking in Fedora Server:
1- Fedora Server doesn’t have any system-config-network package?
2- When I use nmcli command to configuration my NIC and set IPv4.method manual, then why I have not any NIC configuration file under the /etc/sysconfig/network-scripts/ directory?
3- In a local network, can two systems have a same UUID for NIC? Can it make any conflict?
Apparently there is no system-config-network package but there is NetworkManager-tui for a terminal based interface and nm-connection-editor for a graphical interface to configure network connections.
In my Fedora 33 system, new network connections are saved under /etc/NetworkManager/system-connections/ directory. Did you check that directory for saved connections?
What do you mean by UUID for NIC, do you mean UUID of a network connection which is shown when you run nmcli connection show? If so, I think it won’t matter if 2 different hosts on the same network have connections which have same UUID’s because UUID’s are set internally by NetworkManager and aren’t exposed to the local network (but I am not sure on this one since I didn’t test it).
