ifconfig is going away...use ip instead. In this case 'ip addr' The way to set static addresses is to use nmcli conn edit <conn-name>. The connection names are given by 'nmcli conn show'.
You want to alter the ipv4.<propname>'s. I don't have my notes with me but off the top of head you want to change ipv4.method to manual and then fill in ipv4.addresses, ipv4.gateway, and whatever else you need. The fields mix 'ip addr' and 'ip route' settings. Basically that's what nmcli does. It takes the connection profile properties and uses the ip utility to set the nic and its routing info. Good luck. ________________________________________ From: owner-scientific-linux-us...@listserv.fnal.gov <owner-scientific-linux-us...@listserv.fnal.gov> on behalf of Larry Linder <00000dea520dd180-dmarc-requ...@listserv.fnal.gov> Sent: Tuesday, March 17, 2020 11:38 AM To: scientific-linux-us...@listserv.fnal.gov Subject: Revisiting Cent 8 Boss asked us to take another look at Cent 8 because Cent 8 box in corner was using an IP address that is in middle of several machine tools. It had been running since oct 19 and we gave up on it at end of December as basically worthless. I looked at all the pages of directions on the internet and Cent pages for a way to change the IP to a range that is used for our boxes. When you run ifconfig -a you see the configuration and no eth0 or eth1 but you find enp3s0: First I found the configuration tools don't work. network-scrips is now empty. I used yu to install scripts. Edited eth0 to correct address and rebooted as "tool" didn't work. Something is very wrong. The manual pages from RH dont work, other published directions are as if written for system zzz. Cent help pages are useless as they cover Cent 7 and little of no Cent 8 real help. Anybody who has actually changed the IP to static sucessfully - please tell me how they did it. The boss looked at the bill for switching to another OS that is not a derivative of RedHat and maybe a Macks and he wanted us to really look at Cent 8 again. As a business it all the bottom line, there is nothing free. We have a considerable investment in SL from 4 to 7.6 and I would hate to think of the cost of just tossing it all. Is there an alternative desk top as Gnome as it is terrible, You can't have two terminals open at once at least on this system. The only thing that worked was LibreOffice. The rest is nonsensical. As you all can guess is that I am an engineer and not an IT person. Larry Linder
