I used the following nmcli commands: nmcli con delete eth0 nmcli con add type ethernet con-name eth0 ifname eth0 ip4 192.168.129.11/23 gw4 192.168.129.1 nmcli con mod eth0 ipv4.dns "50.253.254.2 192.168.129.1" nmcli con mod eth0 mac "02:67:15:00:81:0B" This created the ifcfg-eth0 file: TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=none IPADDR=192.168.129.11 PREFIX=23 GATEWAY=192.168.129.1 DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_FAILURE_FATAL=no IPV6_ADDR_GEN_MODE=stable-privacy NAME=eth0 # UUID=c05a6a2c-e720-453e-9897-edbc109a9e11 DEVICE=eth0 ONBOOT=yes DNS1=50.253.254.2 DNS2=192.168.129.1 HWADDR=02:67:15:00:81:0B I moved the ethernet cable from the vlan I have been testing with that has dhcp to the 192.168.129.1 vlan that lacks dhcp and ran: nmcli con up eth0 Error: Connection activation failed: No suitable device found for this connection. No addresses on eth0 # ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 02:c4:03:82:c1:53 brd ff:ff:ff:ff:ff:ff inet6 fe80::ba72:3d43:b97:596c/64 scope link noprefixroute valid_lft forever preferred_lft forever I commented out that UUID line, and still nothing on eth0. I moved the cable back to the old vlan and eth0 came right up with its dhcp address, not the one in ifcfg-eth0. So, OK, what is going on here? This worked just fine back in the old 1611 image. What is this ifcfg-link file that seems to be controlling the ethernet connection? How do I get things to work using nmcli? thanks I rebooted, and still no On 08/01/2018 02:04 PM, Robert Moskowitz wrote: > I went looking for /etc/sysconfig/network-scripts/ifcfg-eth0 to set it > up for static addressing. > > Instead I found ifcfg-link > > What is this? > > In the past I was usin nmcli: > > ifname=eth0 > nmcli con delete $ifname > nmcli con add type ethernet con-name $ifname ifname $ifname ip4 > $your_ipv4_address/$your_ipv4_prefix gw4 $your_ipv4_gateway > nmcli con mod $ifname ipv4.dns "$your_ipv4_dns1 $your_ipv4_dns2" > # optionally set your MAC address > # your_mac= > # nmcli con mod $ifname mac "$your_mac" > nmcli con up $ifname > > (that con add above is line wrapping in this email) > > ip a > > shows eth0; do I just use my nmcli script as I did for the 1611 image? > > thanks > > > _______________________________________________ > Arm-dev mailing list > Arm-dev at centos.org > https://lists.centos.org/mailman/listinfo/arm-dev >
