I have a server that cannot generate enough entropy to support /dev/random
. The particular piece of software having problems can't be configured to use /dev/urandom
.
I tried moving /dev/random
to /dev/realrandom
and symlinking /dev/random
to /dev/urandom
, but lsof /dev/realrandom
still shows processes using it.
In Does 'urandom' share the same entropy of 'random'?, the suggestion is to use mknod /dev/random 1 9
. Will this hold across restarts? Should I be using udev somehow?

All you need to do is to create something like
/etc/udev/rules.d/70-disable-random-entropy-estimation.rules
with the following contents:
