/dev/random too hungry? Errormsg: PRNG is not seeded
Hello, I have one box where PRNG kickstart doesn't work. Whne I set 'sysctl kern.random.sys.seeded=0' and 'cat /boot/kernel/kernel.gz > /dev/random' .random.sys.seeded is still 0. On any other box it's enough to send one byte and .sys.seeded returns to 1 I found that when installing a new server and trying to usually start sshd. (ssh-keygen quits immediately with the error: PRNG is not seeded) I'm not very familar with random or entropy stuff so please tell me what to do. Nothing uncommon so far with that box (besides it starts from CompactFlash with memorydisk for /var / and /tmp): kern.random.yarrow.gengateinterval: 10 kern.random.yarrow.bins: 10 kern.random.yarrow.fastthresh: 192 kern.random.yarrow.slowthresh: 256 kern.random.yarrow.slowoverthresh: 2 kern.random.sys.seeded: 0 kern.random.sys.harvest.ethernet: 1 kern.random.sys.harvest.point_to_point: 1 kern.random.sys.harvest.interrupt: 1 kern.random.sys.harvest.swi: 0 interrupt total rate irq0: clk 1038776 998 irq1: atkbd0 2 0 irq3: sio1 2610 2 irq5: em0 133 0 irq7: ppc0 1 0 irq8: rtc 132946 127 irq10: fxp0 72 0 irq12: fwohci0++ 1 0 irq13: npx0 2 0 irq14: ata0 3110 2 irq15: ata1 202 0 Thanks in advance, -Harry -------------- next part -------------- A non-text attachment was scrubbed...
