Hi Andreas, Correct, one place was missed when the urandom patch was applied. Will fix.

Normally we have very low entropy on this machines and I long hangups before authentications because there are no random numbers available. Could be the default maybe /dev/urandom and /dev/random only as a config option? Cheers Andreas.
