Here are some articles, papers, talks and things that I've written:
- In 1992 I gave a talk at the European X Users' Group conference, describing
our X configuration. A modified version of this appeared in
volume 7 of The X
Resource, published by O'Reilly and
Associates. A further modified version was published locally as a
- The slides and examples for a couple of
introductory X toolkit programming talks I gave to fourth-year students
for several years until 1995 are here. Incidentally, the
X Consortium's "hardcopy" documentation
can be found here.
- Here are the slides and diagrams for the
"guest" half-lecture I gave to the CS3 comms course in March 1998. Note that
there's a more recent version
- These are the slides for a brief introductory
talk on ethernet technology that I used at the beginning of an internal
Computer Science meeting in November 1998
to discuss our future network topology...
- ... and these are the slides for a short
presentation on our then-newly-acquired
3Com SuperStack 3300 switches
that I gave at the Edinburgh Science COs meeting in December 1998.
- These are (most of) my slides from the
SciCOs "security" meeting of June 1999. I think the only missing one is of
our IPfilter rules, and that's here.
- Here are the slides for my part of the
EdLUG "security workshop" held on 14th March 2000.
- The slides for my talk at the
Workshop on Computer Security held in November 2000 are available in
.dvi formats. The other contributors'
slides can be found by following the links from
own conference pages.
You might also be interested in the TCP wrappers stuff on
Wietse Venema's home page, the
home page, and the
- In March 2002 I gave the CS3/MSc comms "guest" lecture again, the
subject matter being how and why the CS network has evolved the way it
has over the last 25 years or so. The slides and diagrams can be found
here. Last year's version is still
Graphs of the traffic on most
of our switch ports are also available to EdLAN users.
I've written a
Tnm-based utility to make it easier for our technical staff to
HP ProCurve and
3Com SuperStack 3300
switches. The ProCurve version is here, and the
SuperStack version is here. If you want to
generate MRTG configuration files you can use
I've also written a couple of little monitoring utilities:
MACwatch dumps switch forwarding tables
into a history file (run it from cron every so often;
and note that if you want to get information from a
3Com SuperStack switch for anything other than the default VLAN then you'll
need to enable fastIP); and
Monitor tracks up and down times for switches
You can find my makeDNS utility here --
it's a utility for converting /etc/hosts files into DNS RRs.
Here are a few little X utilities that I wrote
some time ago.
testCard.tar.gz displays some useful patterns on the screen,
xmailwatcher.tar.gz (which we don't use any more, so it's not
maintained!) keeps an eye on a mailbox's contents, and
xquitbutton.tar.gz provides a handy "stop" button for X sessions.
None of them is guaranteed bug-free. On the contrary, at least
one of them is guaranteed to have at least one bug in it.
Some time around 1973 I walked through the railway tunnels above
Glen Farg on the old Edinburgh-Perth via Kinross line.
Here is a note on their location for
anyone who fancies looking for them. (I've no idea what kind of condition
they're in now!)
