"Fun" is an interesting way to put it. Just need to check an IP? "ip addr". Need to up/down an adapter? "nmcli device connect eno16780032" instead of "ifup eth0". Want to verify DNS is working? nslookup doesn't exist anymore, so use "getent hosts <hostname>". "Shutdown" has become "Poweroff". "Chkconfig <service> on" has become "systemctl enable <servicename>.service". Netstat's gone, partially replaced by "ip route show". Want to change the device name to something easier to remember? Good luck. None of the official methods have worked for me so far. Want to change something via a config file? Hahahahahaha... No. We don't do things like that anymore. Need to found out what ports have an established connection? Want to enable promiscuous mode? Sucks to be you! Linux is getting Solaris syndrome, and as a SysAdmin...
We hates it, we do. Thank goodness you can (for now) install the old net-tools. Once they take that out...
