search for: duid

Hi, The use-case is deploying C7 VMs with a pre-set machine-id and default-duid based on the machine-id to facilitate static DHCP with IPv6. The default-duid is found in dhclient6-<value>-eth0.lease and IPv6 DHCP uses default-duid like IPv4 DHCP uses MAC addresses for static DHCP. How does one convert /etc/machine-id to a default-duid (in bash)? 1) /etc/machine-id -&...

Does anyone have a utility or method to show the IPv6 DUID for a client system without relying on looking through a DHCP server's logs or waiting until after a request is made? I'd like to determine a client's DUID before I set it up for IPv6, that way I can have it configured in the dhcpd6.conf file for a static assignment before it gets...

Hi, folks, I and the other admin here have just been assigned a mission... here's what's happening: only very recently - the last week? our CentOS 7 boxes, or at least some of them, will lose their IPv6 addresses, and not get it back. 1. We're running dibbler on the same box that serves DHCP. 2. It's been working for many months. 3. The lease file remains in place.

Ok, what is the windows event log telling you. You should see an error. What is the description and event id. Gr.

...isolated lan between the vm and the host and booted the vm up. I see the vm is up, made sure the vnic is visible in both the host and guest and added it to the br in the guest. I've issued an dhcpd call on the vnic (labeled vnic0) in the host and got an ip, see: dagg@NCC-5001D ~ $ dhcpcd vnet0 DUID 00:01:00:01:23:dd:d8:5b:e0:d5:5e:d9:f2:e2 vnet0: IAID 00:10:20:bf vnet0: rebinding lease of 192.168.1.130 vnet0: probing address 192.168.1.130/24 vnet0: soliciting an IPv6 router vnet0: leased 192.168.1.130 for 43200 seconds vnet0: adding route to 192.168.1.0/24 vnet0: adding default route via 192....
