Description: Step 2.2:
[root@replica1 ~]# nmcli connection modify "System eth0" ipv4.dns 172.25.250.13
Error: Failed to modify connection : could not open file '/etc/sysconfig/network-scripts/ifcfg-eth0' for writing: Permission denied
(changing the permissions on that file did not work either:
chmod: changing permissions of '/etc/sysconfig/network-scripts/ifcfg-eth0': Operation not permitted)
