Hi! (PEBKAC warning. I'm probably doing something dump. I just don't know what...) I seem to have an entropy pool on a headless machine which is not nearly empty (a common problem in this case, I know), but completely empty and stuck in this state... Hornburg:~# cat /proc/sys/kernel/random/entropy_avail 0 Hornburg:~# fuser /dev/urandom Hornburg:~# lsof | grep random Hornburg:~# cat /proc/sys/kernel/random/entropy_avail 0 Hornburg:~# dd if=/dev/hdf of=/dev/urandom bs=512 count=1 1+0 records in 1+0 records out 512 bytes transferred in 0.016268 seconds (31473 bytes/sec) Hornburg:~# dd if=/dev/hdf of=/dev/random bs=512 count=1 1+0 records in 1+0 records out 512 bytes transferred in 0.031943 seconds (16029 bytes/sec) Hornburg:~# cat /proc/sys/kernel/random/entropy_avail 0 Hornburg:~# fuser /dev/urandom Hornburg:~# fuser /dev/random Hornburg:~# lsof | grep random Hornburg:~# cat /proc/sys/kernel/random/poolsize 4096 Hornburg:~# Also causing disk activities doesn't help at all. (Two disks on a Promise PDC20268 controller.) The system runs a rather ancient Debian Sarge 2.4 kernel: Linux Hornburg 2.4.27-3-386 #1 Thu Sep 14 08:44:58 UTC 2006 i486 GNU/Linux However as the machine itself is also ancient, the 2.4 seems like a good match. And also 2.4 ought to have a refilling entropy pool, doesn't it? Maybe someone can shed some light on what's happening here...
