OpenBSD 5.8 Pre-orders are on

I have preordered my copy of OpenBSD 5.8 which will be released on October 18 which deraadt says is the anniversary of a Makefile he first committed in the OpenBSD tree. It's the OS's 20th anniversary. If you're interested in obtaining OpenBSD on CDROM go to https://openbsdstore.com and look for OpenBSD version 5.8. Be sure to click on the EU symbol if you want to pay in euros. With my preorder I also ordered a poster this time. It should look good in my apartment.

And still in the Rush...

I couldn't resist looking at raspberry pi stuff and came across a battery pack unit. I thought this was good for a portable CryptoPi made the same way as a CryptoBook, only cheaper. If it works out I'll be able to exchange it with my Uncle who by now is in possession of the silver cryptobook.

Still in a Consumer Rush

I'm still in a consumer rush. I hope it quells soon. I just purchased another quad gigabit ethernet card for my soekris router. This brings the gigabit ports on the soekris to twelve. I'm also very interested in the raspberry pi for some reason again. Not so much the rpi that I have but the rpi 2 which has double the RAM and 4 cores. If I were to put together the soekris and 10 RPI boards I'd have a small supercomputer. I'm currently testing the possibility of this. I'm brainstorming uses too.

I started shuffling my $HOME/.ssh directory

There have been reports (real reports) of firefox allowing a remote attacker from reading ssh keys. To make it harder on the attacker I'm shuffling my .ssh directory with this script:

#!/bin/sh

TMPDIR=`mktemp -u /home/pjp/.ssh-XXXXXXXXX`
BASE=`basename $TMPDIR`
SSHLOCATIONX=`find .ssh* -name sshlocation -print`
SSHLOCATION=`dirname $SSHLOCATIONX`

mv /home/pjp/${SSHLOCATION} $TMPDIR

sed -e "s/@XXXXXXXXXX@/${BASE}/g" \
/home/pjp/.ssh/config.template > /home/pjp/.ssh/config

exit 0

I shuffle every 5 minutes per crontab.

Spampd and taking the -T out

I must have wasted 2 hours trying to get spampd to work on a FreeBSD jail with most recent ports. This was the error message:

Aug 09 11:15:51 testmail spampd[86796]: 2015/08/09-11:15:51 Insecure dependency

Ordered a Book from Amazon

I bought Design and Implementation of the FreeBSD Operating System, by McKusick et al. Second edition! Having looked through this book I can tell it'll be insightful. I bought the Design and Implementation of the 4.4BSD Operating System from the same author around 1996. I had struggled with it, it's not an easy read and they recommend a Tanenbaum for newbies first. Which I did, (buy a Tanenbaum) and it was worth it. Now only I hope there is some similarities left between FreeBSD and OpenBSD like mbuf's. :-). Can't port something without understanding both systems anyhow. So.. that only leaves someone to write Design and Implementation of the OpenBSD System, hint hint. Anyhow I think this McKusick book will be great.

.. and a Riddim

There is only four songs on the Cloud Nine Riddim. But it's sweet. Too bad they couldn't pack-in an instrumental to this.

Bought Reggae

I have purchased Romain Virgo's album "The System", it's an older album but I used to watch his videos on youtube.

CryptoBooks virtualized

In order to make use of cryptobook in more parts of my family I have virtualized it. That sorta defeats the point but buying a cryptobook does tend to get expensive. Here is a vmware version of cryptobook:

And here is a virtualbox version of cryptobook:

These aren't for sale unfortunately.

Delphinusdnsd status update

Well the hot days are over I believe. So I'm itching to get back to this. Perhaps next week I'll be able to write some code as this week is filled in my schedule.
