You can always try to run dhclient directly: dhclient eth0

Well this seems to have problems:

years ago!) but once you get use it it is much nicer. There's a quick start here http://andys.org.uk/bits/2010/02/24/iproute2-life-after-ifconfig/ or you can do "yum install net-tools" and get the old ones back.

Whow, I have been asleep at the switch on this one. Did not see it in any notes, but then that is more than likely my fault. So I got a lot of reading to do, and then figure out why no IP addresses (v4 or v6) are getting assigned. I figure out enough of the IP command to see no addresses. Even if there is a problem with my DHCP server, I am sending out RA messages, so there should be a global IP address. I will dig a bit and see if I can get addressing to come up properly.

Of course with no addressing, the address I *THOUGHT* this box took was actually another test box that has SSH on another port, of course ssh was not connecting. 'firewall-cmd --list-all-zones' shows that the ssh service is allowed in; no change to default setups there.

ANd I cannot install net-tools until I get addressing working.

The other useful command is nmcli which is the NetworkManager command line. You could also try a plain old "ifup eth0" and see if that makes a difference.

Looks like more digging is called for:

# ip addr show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default 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 pfifo_fast state UP group default qlen 1000 link/ether ce:52:c8:ae:9a:66 brd ff:ff:ff:ff:ff:ff

# ifup eth0 /sbin/ifup: configuration for eth0 not found. Usage: ifup <configuration>

Could it be that the MAC addr is local scope? But this is needed on many SOC boards; not unique to Cubies.
