SCO Zenix and Unix
first stated with Unix in 1985 when I was the technical
director of my own company with a product called SCO
Xenix (Santa Cruz Operation), and later to become
SCO Unix. This was mainly installation and system
administration Intel platforms for our customers and we
also ran our own system in house for development.
In May 1993 I started
contracting, and wrote a communications interface using
Berkeley sockets between an Intel PC running Telephone
Operator Console (GPT, Poole) and an HP9000 from Hewlett
Packard running the HP-UX operating
later moved to Holland to work for Siemens Nixdorf who had
their own variant of AT&T System V Unix called Sinux.
This ran on their own hardware. I was mainly responsible for
support of the TCP/IP stack in the Unix Kernel and was all
very low-level work. I also wrote an interface between UUCP
( Unix to Unix Copy Program) and their .X25 interface card.
UUCP was what the Unix world used for communications before
the Internet became popular. This job also involved a lot of
Unix installation and administration, Korn shell scripting,
web server implementation and the like.
In January 1996 I worked
as a consultant for Nedlloyd Lijnen ( Now P&O Nedlloyd
shipping ) in Rotterdam. This company ran Sequent Symmetry
platforms running Dynix/pt. This project was primarily
disaster planning but I also did some administration and
shell scripting for DNS improvements.
Back in the UK, I
continued writing communications interfaces using C++,
Berkely Sockets, Remote Procedure calls and Serial
communications protocols on Sun Sparc (Sun Solaris), Dec
Alpha 2100A (BSD based HP-UX) and a
Posix compliant embedded operating
system called QNX
(QSSL Canada). This was for a project for
Mass Transit Railway Company in Hong Kong and the Light Transit railway system in Kuala Lumpur. I also
installed and administrated Thorn Transits own Solaris and
Digital Unix platforms. This involved user administration,
DNS, DHCP, NFS, Auto-mounter and other admin activities. I
also worked with E-mail systems (Elm) POP,SMTP and PC
My largest Unix based
project was the Swedish Civil Aviation Authority using
Digital Unix (5.04D) on DEC Alpha Servers and Workstations.
This was for two new en-route Air Traffic Control Centres. I
wrote all of the commissioning procedures for this project,
training the implementation team in Sweden and The UK.
I supervised the commissioning of 50 Digital Unix
servers and some 150 workstations.
At Colt-Telecom in
Amsterdam I set up of a network monitoring system based upon
HP Openview, NNM, Customer views on two Sun Solaris 7.0
platforms (Sun E220R and E240R). I also carried out other
installation and Systems administration work at this time.
am currently working at for a leading Pharmaceutical
company in Belgium on HPUX 11.0
platforms running HP-Openview. This also involves system
administration (SAM ,NFS etc.)
I generally try to
look for projects with a strong Unix and networking content.
I donít particularly seek contracts doing Unix
administration but with the length of experience I do have
the necessary skills to do the job.
