Trying to use haveged to address entropy starvation that is creating problems for Apache and PHP-FPM at boot (no HWRNG)

Hi,

I'm sorry to hear that.

Which version of haveged are you using? Could you please try to use Ubuntu 20.04 and send me the outcome?

Thanks Jirka

weaselBuddha commented 3 years ago

apt install haveged : haveged is already the newest version (1.9.1-6).

Download and compile the most recent? Upgrading to 20.04 is not an option.

jirka-h commented 3 years ago

Hi,

could you please try to install the latest haveged : https://github.com/jirka-h/haveged/releases/tag/v1.9.15

and compile it with ./configure make

If the compilation is successful, install it with sudo make install

Thanks Jirka

weaselBuddha commented 3 years ago

Ok, that fixed it.

To make on 18.04 I had to:

touch aclocal.m4 configure Makefile.am Makefile.in

To address the problem of "make error - aclocal-1.16: command not found" (18.04 has aclocal 1.15)

I also used the haveged.service from the ubuntu repo install

Command line, via systemd:

/usr/local/sbin/haveged --Foreground --verbose=1 -w 1024

jirka-h commented 3 years ago

Hi,

I'm glad that the new version is working for you!

I'm sorry for the problems with compilation. Next time, you can use autoreconf -fiv - it will generate a new ./configure script for your system.

autoreconf -fiv
./configure --disable-enttest --enable-nistest --disable-static
make

Cheers, Jirka
