nmcli - a hands-on Linux lab on a real virtual machine.
The RHCSA basic-networking capstone on a real RHEL 10 machine. Wire a static IPv4 connection, add IPv6, set the hostname, add a static host entry, and open a firewall service, graded on live end-state. Mission mode.
You have finished the Basic Networking module. Now you wire the network on a real RHEL 10 machine: a static address, a second protocol, the right name, a host mapping, and an open service. Every piece is graded on the live result, exactly like the exam.
Five objectives, one real machine. You work on a spare interface named labnet so nothing you do can knock the server off the network.
This is mission mode. No commands are shown. You read the objective, recall the tool, and configure the link. You will need root, so reach for sudo. Progress checks itself against the live system.
One quick rep before you start. Before you open a service in the firewall, you check which zone is in charge. Ask firewalld for its default zone.
prompt: [root@servera ~]# answer: firewall-cmd --get-default-zone output: public hint: firewall-cmd answers with one word here: firewall-cmd --get-default-zone
public is the zone your interfaces sit in by default, and the zone your firewall changes will land in. Now bring the uplink online.
Boot the machine below and take the console. Read ~/UPLINK.txt for the checklist. Five objectives: a persistent labnet connection with static IPv4 10.10.10.5/24, the IPv6 address fd00:10::5/64 on the same connection, the static hostname uplink.example.net, a host entry so peer.example.net resolves to 10.10.10.9, and the http service opened permanently in the firewall. Work as root, and make every change stick.
Practice Mission Control: Operation Uplink in a real Linux terminal at The Linux Camp. Progress is verified automatically as you type commands on the machine.
