dhclient (ipv6) doesn't work for ppp devices. At least for me this is neccessary to retrieve stateless IPv6 information (dhclient -S) that is otherwise unavailable (IPv6 name server address list). Reproducible: Always Steps to Reproduce: dhclient -S -d ppp0 Actual Results: Bound to *:546 Unsupported device type 512 for "ppp0" Expected Results: Working dhclient. See e.g. https://bugzilla.redhat.com/show_bug.cgi?id=626514 for details.
Created attachment 322144 [details, diff] dhclient ppp fix The patch fixes dhclient to be usable on ppp devices. It is based on https://lists.isc.org/pipermail/dhcp-users/attachments/20100426/9deb431f/attachment.bin and enhanced to generate a DUID necessary for dhclient operation. With the attached patch "dhclient -S ppp0" succeeds for me.
I can confirm. Without this patch all i get is: Bound to *:546 Unsupported device type 512 for "ppp0" This is becomming a little bit important. The biggest german ISP is now starting to roll out native IPv6. PPP will only handshake a link local addr, everything else (dns, delegated prefix, etc) needs DHCPv6 over PPP. from the Fedora Bug report, this seems the way it is supposed to be: https://datatracker.ietf.org/doc/draft-ietf-v6ops-ipv6-cpe-router/
The patch no longer applies
