| Summary | 0007525: dhclient fails to assemble DUID while requesting IPv6 prefix delegation | ||||
| Description | Client needs to establish PPPoE session in order to get internet connectivity. IPv6 address for ppp0 interface is obtained automatically via RA (net.ipv6.conf.ppp0.accept_ra=2). To obtain IPv6 prefix delegation client needs to send DHCPv6 PD request. Running dhclient -d -P ppp0 fails with output: # dhclient -d -P ppp0 Internet Systems Consortium DHCP Client 4.2.5 Copyright 2004-2013 Internet Systems Consortium. All rights reserved. For info, please visit https://www.isc.org/software/dhcp/ Bound to *:546 Listening on Socket/ppp0 Sending on Socket/ppp0 xid: warning: no netdev with useable HWADDR found for seed's uniqueness enforcement xid: rand init seed (0xfb37fe49) built using gethostid Cannot form default DUID from interface ppp0. PRC: Soliciting for leases (INIT). XMT: Forming Solicit, 0 ms elapsed. Failure assembling a DUID. Failure assembling a DUID. This version of ISC DHCP is based on the release available on ftp.isc.org. Features have been added and other changes have been made to the base software release in order to make it work better with this distribution.
