haveged (a simple entropy-gathering daemon)
|
||||
|
||||
The haveged project is an attempt to provide an easy-to-use, unpredictable
|
||||
random number generator based upon an adaptation of the HAVEGE algorithm.
|
||||
Haveged was created to remedy low-entropy conditions in the Linux random
|
||||
device that can occur under some workloads, especially on headless servers.
|
||||
|
||||
The HAVEGE algorithm is based upon the indirect effects of unrelated hardware
|
||||
events on the instruction timing of a calculation that is sensitive to
|
||||
processor features such as branch predictors and instruction/data access
|
||||
mechanisms.
|
||||
Samples from a high-resolution timer are input into the algorithm to
|
||||
produce a stream of random data in a collection buffer. The contents of this
|
||||
buffer can be fed into the random device or accessed directly through the
|
||||
file system. File system access is a useful alternative to those situations
|
||||
where use of the random device is either inappropriate or not available.
|
||||
|
||||
Add the following snippet to your /etc/rc.d/rc.M to start up haveged at boot:
|
||||
|
||||
# Starting HAVEGED entropy daemon
|
||||
if [ -x /etc/rc.d/rc.haveged ]; then
|
||||
/etc/rc.d/rc.haveged start
|
||||
fi
|
||||
|
||||
You can see how many bits of entropy are available to the system by reading
|
||||
the /proc/sys/kernel/random/entropy_avail file, and check the size of your
|
||||
entropy pool at /proc/sys/kernel/random/poolsize.

# HOW TO EDIT THIS FILE:
|
||||
# The "handy ruler" below makes it easier to edit a package description.
|
||||
# Line up the first '|' above the ':' following the base package name, and
|
||||
# the '|' on the right side marks the last column you can put a character in.
|
||||
# You must make exactly 11 lines for the formatting to be correct. It's also
|
||||
# customary to leave one space after the ':' except on otherwise blank lines.
