Introduction
I solve problems. Currently those problems
deal with local area networks and TCP/IP. Most of the time I am able to do this
from my office, speaking to customers on the phone, logging into their systems
via a dial up line and using remote diagnostic tools. On occasion I travel to
the customer site, anywhere in the
While in my current job I do not write
application programs, I constantly review other people's programs both to find
bugs and to understand how they work. I also write test programs to isolate
bugs. If a bug is critical I may provide a fix to the customer. I have also
written several Windows shareware programs in Visual C++. These activities have
kept my programming skills sharp.
I enjoy writing. Besides numerous Stratus presentations and articles for the Stratus Users Group newsletter
and the Stratus
Customer and Partners eNewsletters, I have
written a number of technical
articles on networking topics and product reviews.
I am a firm believer in continuing education. Whenever possible I
attend seminars on new and potentially important topics. In addition I read
constantly, both trade journals and networking texts.

Work History
|
11/87 to Present |
|
I am responsible for resolving critical
customer problems dealing with Ethernet and the TCP/IP protocol suite, on all
five of Stratus' operating systems, VOS, FTX, HP-UX, Microsoft Windows
2000/2003 and Linux. Problems range from bugs in Stratus software to incorrect
system configuration or application design and network failure or performance
problems caused by bad network design or failing equipment. Many times
resolution of network problems requires analysis of a protocol trace and Layer
2, 3, and 4 statistics. Most of the time I use remote debugging tools built in
the operating system or 3rd party tools like a protocol analyzer with remote
access capabilities. When necessary I travel to customer sites for on-site
analysis and resolution of problem. For critical problems that I identify as
bugs in the operating system or utilities I will code a fix and send patches to
the customer. I also act as a consultant to other customer support personnel.
In addition to problem solving I write and
present tutorials both internally and to customers. I have presented tutorials at the Stratus Users conference, the
Stratus World conference and the Continuous Availability Summit. I have also
written numerous articles
on networking. These articles include tutorial information and tools written in
C, Perl and the proprietary Stratus VOS command language. Some of these are
published in the Stratus Users Group and the Stratus Customer and Partner eNewsletters.
Special projects have included simulating a
customer's network with 3,000 hosts, the development of an LPD client for the
VOS operating system, a version of UUCP for FTX and the development,
maintenance and periodic presentation of a 1-week class introducing LAN
concepts and the Stratus LAN hardware, and software. I have also developed a
set of Perl scripts and Excel macros for the analysis of TCP protocol traces
and diagnosis of TCP performance problems.
Prior to my specialization in the
communication area I resolved problems dealing with Oracle and Sybase databases
on VOS.
