Ah ha! I solved that one about a month ago... (I believe I posted the
diffs at the time?!?)
There is a problem in the way the PPP code registers the IP addresses on
both ends of the connections into the kernel's interface structures: PPP
doesn't fill in the "size of structure" field of the IP address, which
means that bind will never find the addresses (sigh).
The diffs for that problem appear below...

Hmmm. That's odd, I've not seen that one. I'd venture it's probably
something in your set-up.
But anyway, install the following patch and then try ftp or ping and
let us know how it turns out!
Happy PPPing!
