ODROID-C1: HW RNG and haveged

[sgrin]

Newbee questions again:

Does Archlinux use hardware random number generator of ODROID-C1?

Do we need running haveged service?

[mdrjr]

All you need is rng-tools installed and running.

Thanks for reply.

I stopped haveged service and run
$this->bbcode_second_pass_code('', '[root@alarm ~]# dd if=/dev/random of=/dev/null bs=1 count=1000
1000+0 records in
1000+0 records out
1000 bytes (1.0 kB) copied, 30.1222 s, 0.0 kB/s
[root@alarm ~]# cat /proc/sys/kernel/random/entropy_avail
257')
Changed /etc/conf.d/rngd to be:
$this->bbcode_second_pass_code('', 'RNGD_OPTS=""')
Started rngd service and run
$this->bbcode_second_pass_code('', '[root@alarm ~]# dd if=/dev/random of=/dev/null bs=1 count=1000
1000+0 records in
1000+0 records out
1000 bytes (1.0 kB) copied, 0.0749507 s, 13.3 kB/s
[root@alarm ~]# cat /proc/sys/kernel/random/entropy_avail
3386')
It seems working ok.

/etc/conf.d/rngd should be:
$this->bbcode_second_pass_code('', 'RNGD_OPTS="-o /dev/random -r /dev/hwrng"')

It seems that rngd guessed the right options
$this->bbcode_second_pass_code('', '[root@alarm ~]# lsof | grep rngd
rngd 818 root cwd DIR 179,1 4096 2 /
rngd 818 root rtd DIR 179,1 4096 2 /

Сhanged the config however.

Thanks.
