The purpose of this page
This pages provides personal information and some links to pages
I've made in the past.
My name is Otto Moerbeek, I live in Heemstede, the Netherlands together with
my wife and daughters.
I work as software engineer with
In my spare time, I participate in the development of
OpenBSD, a FREE,
multi-platform 4.4BSD-based UNIX-like operating system,
which emphasizes portability, standardization, correctness,
proactive security and integrated cryptography.
My contributions to OpenBSD include major work on utilities like
patch(1) and diff(1), new versions of dc(1) and bc(1), privilege
separated tcpdump(8), work on ntpd(8) and kernel time code, large
partition and ffs2 support, pcc, a complete rewrite of malloc(3) which
has many nice features, work on the
lots of bug fixes in almost every area, code auditing and more.
Recently, I have been working on code to replace the now defunct Enecsys
PV monitoring site. My php
listens to the Enecsys gateway and sends data
to pvoutput.org and optionally MySQL.

Running Apple's Backup Without a .Mac Account
These pages describe a nice trick I found out.
If you are interested, you can read the discussion about these pages on
The description now includes how to perform the trick using Backup 3, the most recent version.
March 27, 2002 I did present a Birds-of-a-Feather
session at the JavaOne conference in San Fransisco.
In this session, I talked about some security issues of agent platforms
and how to solve them using Java™.
The abstract of my session used to be available
but Sun decided to pull it.
A PDF file containing the
presentation slides is also available.
A tar archive containing the complete source code of the examples can be found
can also browse the source code.

Harry Smits, informatie over
zijn toneelstukken is my Father in Law's site about his plays. This site

Looking for Otto's LinuxPPC Goodies?
They are here. Please beware, a lot of this
information is a bit out of date. These pages also contain a
description of a project I
did to add support of a KeySpan PCI serial card to Linux(PPC).
The patches I made
are now part of the standard Linux serial driver serial.c.
This site used to be served from a i386 machine in the wall closet running
OpenBSD as its operating system
and nginx as its http server.
For some time the machine has been colocated, but now it's back home,
incarnated as a fuloong machine and still running OpenBSD.
