As you can see, there is no SHA2 problem present (see 47.html).
Switching the phase2 hash to ripemd didn't help.
Any ideas about what to do?
The reason for not yet upgrading everything is that road warriors (NCP)
are stopped dead in much the same way like shown above, when running
against 4.9 (but not if they work against lower versions of OpenBSD,
including 4.8). If I could verify that they'll work, I'd uprade rather
sooner than later.
