5), including equipment and vendor selection, resulting in substantially
less network incidents
Scripted the creation of DNS configuration files, using a well formatted
"hosts" file for input, allowing others to perform simple additions while
maintaining a good configuration
Designed and implemented split horizon DNS services, for local office
necessary due to reliability of circuit to Boston
Designed, implemented and maintained fully redundant dhcpd services, to
allow better control of network configurations, also increasing the
reliability of our network
Noticed improved stability and performance of the network after
implementing NTP services.
Monitored the corporate email services (SMTP), including popd servers,
later converted popd services to exchange (though I recommended against
this and still do, I implemented the necessary changes)
Initiated an internal web service, allowed for more consistent sharing of
local office documentation.

more consistent configuration of desktop PC's

xterms, bootp, tftp, nfs and a few well placed scripts. Allowing the use of
existing hardware (xterms), to be used for various training sessions. Which
required that I design and implement a tunnel for customers to access their
email, without access to our network
Implementation of backup and data recovery plans.

support for ClearCase version control / file system. Including data
extraction and recovery. Also asssisted developers with perl triggers.

instances (Sequent OS installation, required hex ip address, where others
the typical dotted decimal notation)
14 Martin Marietta (1981-11/1995-
05)
Systems/Network Administrator Waterton CO
Tier one and two user support - supporting aerospace engineers
Secret clearance, which included extensive background investigation for
project specific clearance.
Day-to-day systems administrative services to a large number of non-
heterogeneous UNIX workstations
Design, implementation and maintenance of report reformatting tool. Using a
combination, of C, gawk, bourne shell and understanding of LPR print queue,
created a tool to parse, reformat a 50 ream report reducing the delay in
deliver from 3-4 days, immediately after printing.
Design,implementation and maintenance of time accounting system, as well as
report generation. Written in Fortran IV on Prime, and updated version
written in Pascal on Elxsi, and subsequent C version implenmented for Unix
(which also required a replacement of the login executable).
Design and implemented print queue, for banners on classified documents.
Eventually replaced by adding procedures to change the paper feed into line
printers (because the printer did not allow for "color" printing of the
banner).
Design, implementation and maintenance of remote printing service, using a
Unix node to provide the Queue and the Columbia AppleTalk Package to
perform the transmission to various EtherTalk printers. Subsequently, a
mail response daemon was provided to allow printing to virtually any
EtherTalk connected printer on the corporate network (documented using
groff, with appropriate man pages). Also implemented a curses based
"chooser" in C, to allow users to specify the particular printer of choice.
Implemented a state machine (for postmortem analysis of network data stream
via TCPDump), while designing and diagnosing a network printing service.
Designed, implemented and maintained cgi/web service which allowed
specific, more traditional "operator" functions (typically re-starting
failed services and print queue administration) to be executed without full
root privileges,
Automated the creation of HTML system performance and utilization reports,
using postscript for graphs.
addhoc scripts and tools, used to demonstrate proper usage of system
features.
wrapper program, written in C, that would open a network port as root, then
switch user -- passing a copy of the open descriptor to the forked process.
parsed a single large *.h file of C functions, using awk, separating each
function to it's own file.
a pair of scripts, to assist developers with checkin/checkout
standardization. Used a flat file database to organize the specific file
structures.
Design, implement and maintain password propagation tool, when Yellow Pages
(the predecessor to Network Information Services) was not compatible across
various vendor's versions of Unix. Had the additional benefit of reducing
overhead as the full features of YP were not necessary.
Design, creation and maintenance of sub-nets with root and/or delegated
dns, ntp, dhcpd, bootp, tftp, nfs, smtp services, rudimentary firewall, as
well as isolated classified networks. Some networks, required the use of
uucp due to their periodic connection and extremely remote locations.
Virtualized applications, such as anonymous FTP servers through use of
'chroot'.
Installation and system configuration (including kernel re-build/re-link as
appropriate) for Oracle, Informix, and other software.
Installation and maintenance of mini-computers from vendors: Apollo,
Digital, Elxsi, HP, Prime, Silicon Graphics, Soulborne, Sun, Windows, Mac,
VMS, SysV and BSD unix, Linux ... including the use of cross-platform tools
such as pc-nfs, and x11 emulation tools.
