randomness entropy in DomU
Hello.
I was just digging around in the net and found the thread
http://lkml.org/lkml/2006/5/12/103
So my questions: Are there any (good) news concerning the implementation
of /dev/random in the kernel?
I just cat /proc/sys/kernel/random/entropy_avail
and saw I have about 250 in the DomU''s and 3500 on Dom0. I haven''t even
started to implement encryption for the different kind

scp problem
Hello.
Since some days I cannot use scp anymore but ssh login work. Reinstall
did not help. I do not exactly what has changed but I now it used to
work.
sshd runs on a firewall-bastion host (Linux SuSE 9.2).
Firewall is open on port 22 for local network. Even tried all open (in
and outgoing).
Between the clent and the firewall-bastion is another nat-router. Works
with ssh, though.

Killing the builtin entropy code
Over the holidays, I intend to finally rid portable OpenSSH of the
builtin entropy collection code. Here's what I intend to do:
When init_rng is called, we'll check OpenSSL's RAND_status(). If this
indicates that their PRNG is already seeded, we'll do nothing. This
effectively detects platforms which have /dev/urandom (or similar)
configured into OpenSSL.
If OpenSSL isn't

nut-upsd on mac os
Hello.
I have an cheap seriell to usb adapter with the Prolific chipset
hooked on my mac, but I don't know which tty to configure. OS X
regognizes the device in its system profiler.
/dev/ttys0 seems wrong.
Can someone please enlighten me?
Thank you for your help!
Greetings,

(gang?)block layout question, and how to decipher ZDB output?
Hello, all
I''m "playing" with ZDB again on another test system,
the rpool being uncompressed with 512-byte sectors.
Here''s some output that puzzles me (questions follow):

EL9 says: pcp-pmie[2870]: Low random number entropy available 15.6%
Hi,
I've discovered an issue which I don't understand. On a new test install
of EL9 I saw this message in the logs:
Mar 01 08:09:18 <hostname> pcp-pmie[2870]: Low random number entropy
available 15.6%avail at beta.corp.invoca.ch
This is on a 64 core "AMD Opteron(tm) Processor 6282 SE" server but I also
got the same low entropy on an EL9 KVM guest running on a "AMD

Low random entropy
I am use to low random entropy on my arm boards, not an intel.
On my Lenovo x120e,
cat /proc/sys/kernel/random/entropy_avail
reports 3190 bits of entropy.
On my armv7 with Centos7 I would get 130 unless I installed rng-tools
and then I get ~1300. SSH into one and it drops back to 30! for a few
minutes. Sigh.
Anyway on my new Zotac nano ad12 with an AMD E-1800 duo core, I am
seeing 180.

Recurrence plots in R using different colours
Hello,
I am an absolutely beginner with regards to R, so forgive me for my
potentially very stupid questions.
I have been attempting to create recurrence plots using R. The data I am
using is based on a mutually exclusive and exhaustive coding scheme with
over 40 individual codes which can be assigned to 6 higher order categories.
When I carry out the usual rqa command, my plot is pretty much

Status of hardware performance counters in Xen
Hello everyone,
I''m wondering what the current status of hardware performance counter
usability in Xen is. I see some old posts describing the diffculties of
virtualizing hardware counters within dom0 and the domUs, but not much else.
Have they been implemented or are they in the process of being implemented? Or
are there no future plans for implementation? Any help would be
