Terms:

• CentOS 8:

CentOS 8 is the newest version of the CentOS operating system. It can be downloaded here. In our most recent lab, we used it to learn how to use cockpit, which allows a user to remote manage other machines using a browser.

• nmcli:

nmcli is basically just another way to manage the network adapters. It serves the same purpose as nmtui, which the exception that, rather than a gui, it uses the command line. In order to use it, you must type nmcli, followed by whatever you want to use it for. For example, nmcli con show, or nmcli connection show, will display the network adapters. You can create new ones, modify old ones, and bring them up and down. I'm sure there is much more, however.

• Cockpit

Cockpit is a web based way of managing the machine it's installed on, and other machines. You can access the terminal of the machine selected, the logs for the machine, storage, networking, accounts, and more. It seems really handy, and definitely something I'd like to grow accustomed to. In order to install it, one must do the following:

---

• yum install epel-release
• yum install cockpit
• yum install cockpit-dashboard
• systemctl enable cockpit
• systemctl start cockpit
• firewall-cmd --permanent --add-port=9090/tcp
• firewall-cmd --reload
• You access it with http://10.0.5.234:9090
