That's the question. The only thing I saw that these two programs normally send 123/UDP packets to query the configured timeservers, but apparently these packets are blocked until crng is initialized. At least "rdate" uses "getrandom", that's what you see rdate is waiting for when you "strace -p <pid rdate>" -- ___________________________________________________________________ It is better to remain silent and be thought a fool, than to speak aloud and remove all doubt. +------------------------------------------------------------------+ | Richard Lucassen, Utrecht | +------------------------------------------------------------------+
