The purpose of this page

This pages provides personal information and some links to pages I've made in the past.

Personal Information

My name is Otto Moerbeek, I live in Heemstede, the Netherlands together with my wife and daughters.

I work as software engineer with Efficiency-Online.


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 OpenBSD/loongson port, 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 script listens to the Enecsys gateway and sends data to and optionally MySQL.

Running Apple's Backup Without a .Mac Account

These pages describe a nice trick I found out. Look here. If you are interested, you can read the discussion about these pages on Slashdot.

The description now includes how to perform the trick using Backup 3, the most recent version.

JavaOne 2002

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 here, 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 here. You can also browse the source code.

Site(s) hosted by me

This site's statistics can be found here.

Harry Smits, informatie over zijn toneelstukken is my Father in Law's site about his plays. This site is in Dutch. Its statistics can be found here.

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 Please beware, a lot of this information is a bit out of date.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. Please email comments to Otto Moerbeek
