Thanks for the confirmation (it is helpful!).

I found the problem and that is that rp-pppoe requires PF_PACKET sockets, which are disabled on my kenrel.

I'd really like to avoid this. It seems rp-pppoe uses packet sockets to get the inteface number. Anybody knows if this can be avoided with a bit of hacking?

Otherwise, we should mention that Kernel PPPoE depends on PF_PACKET :(
And improve the error mesages of rp-pppoe.

Now when I type
pppd eth0
I get
unrecognized option 'eth0'

But wasn't the plugin supposed to enable this device?
If I use this script in /etc/ppp/peers/mydsl
#
# PPP over Ethernet options (using roaring pinguin external program) #
plugin rp-pppoe.so
It work for me with this exact line
plugin rp-pppoe.so eth0
...
Then you should be able to do
pppd call mydsl

PF_PACKET sockets are also required to be able to send/receive raw ethernet frames in order to negotiate the PPPoE session, and thus rp-pppoe depends on them. It's not just a matter of getting the interface number; PF_PACET sockets are integral to the functionality of this plugin.
