Description Andreas Steinmetz 2012-08-25 01:20:18 UTC
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. for details.

dhclient ppp fix

The patch fixes dhclient to be usable on ppp devices. It is based on 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:
