Hi Robert,

Just want to check I'm not missing something.
watch --interval 0.5 cat /proc/sys/kernel/random/entropy_avail shows numbers
between 120 and 180.
So I:
sudo aptitude install ekeyd-egd-linux
sudo iptables --append OUTPUT -p tcp --dport 8888 -d 212.13.194.102 -j
ACCEPT
sudo ekeyd-egd-linux -H 212.13.194.102 -p 8888 -b 2 -r 10 -D /root/entropy
netstat shows the expected connection as established, yet watch --interval
0.5 cat /proc/sys/kernel/random/entropy_avail behaves in the same way.
I'm convinced I'm missing a step but can't see it, can any one else?
What does:
sysctl kernel.random.write_wakeup_threshold
say?
This is the level at which the kernel asks for more entropy. By
default it tends to be 128. The init script for ekeyd-egd-linux
(which you aren't using) sets it to 1024 by default. Feel free to
set it at 4000 or so if you like.
sudo sysctl kernel.random.write_wakeup_threshold=4000
Cheers,
Andy
