AUUG Canberra Summer Conference and Workshops 96

To complement the AUUG National Winter Conference, a series of local
summer conferences and workshops are held in Feb-May each year,
organised by the various AUUG chapters. These conferences feature
local and national speakers on a range of subjects, and are used to
help members keep abreast of new developments in the Open Systems
arena. They are also an opportunity to try some networking of the
non-wired variety.

The Seventh AUUG Canberra Summer Conference and Workshops series,
organised by the Canberra Chapter of AUUG, will be held at the
Australian National University on 12-14 Feb 1996.

The following information is correct at present, but may be subject to
some final changes.

Further information is available by: 
Phone:  AUUG Secretariat on 1-800-625-655


The workshops will be held on Monday 12th and Tuesday 13th February at
ANU at 9am and 1:30pm.  Registration will be in the Manning Clark
Foyer. Morning and Afternoon Teas will be provided. Lunch is NOT
provided, but there are several luncheon spots within easy reach. You
can attend workshops without attending the conference. The size of
each workshop is limited, first come, first served. We reserve the
right to cancel any workshop, in which case a refund will be arranged.

Workshops available are: 

Monday 12 February - morning

1 - Domain Name Service (1/2 day) - Mon AM
Chris Vance, ADFA

The Domain Name Service (DNS) is an essential component of any
organisation managing their own Internet system. This workshop will
introduce some of the procedures necessary in creating and managing a
DNS server. The workshop will address standalone route (isolated)
configurations, firewall configurations, as well as the more
conventional configurations.

2 - A Cryptography Primer (1/2 day) - Mon AM
Lawrie Brown, ADFA

Data encryption algorithms form an important technical component in
providing secure and authenticated electronic security and
communications. This workshop will provide an overview of the field of
cryptography, from classical cryptography to modern private and public
key encryption algorithms; their use in providing secrecy and
authentication for data; to some of the practical systems that use
these algorithms for authentication, key exchange and secure email.

Monday 12 February - afternoon

3 - Stretching the Web (1/2 day) - Mon PM
Lawrie Brown, ADFA

The world-wide web is one of the hottest topics in networking at
present, and there's a lot of interest in authoring material for
it. Whilst creating static html documents is relatively
straight-forward, the real interest and value comes in the usage of
more advanced features such as clickable imagemaps, the use of client
or server side includes, and the creation of dynamic html documents
using scripts. These facilities may be used to provide much better
interaction with users browsing your web area. This workshop will
introduce the use of these features, enabling to you to stretch your
usage of the web.

4 - Sendmail 8 (1/2 day) - Mon PM
John Barlow, Daedalus Integration

This tutorial will look at the installation and configuration of
sendmail 8. Included will be information applicable to configuring
most releases of sendmail and a run-down of some of the problems you
can encounter. Some advanced applications and useful tools will also
be discussed.

Tuesday 13 February - morning

5 - Unix and Internet Security (1/2 day) - Tues AM
Jeremy Bishop, Department of Defence

This tutorial will provide an introduction to Unix and Internet
security, and discuss the installation, configuration and use of a
number of freely available security packages including tcp_wrappers,
tiger tools, tripwire, skey and OPIE. Attendees should have some
familiarity with Unix system administration.

Tuesday 13 February - afternoon

6 - Firewalls (1/2 day) - Tues PM
Lawrie Brown, ADFA

The Internet continues to grow exponentially, and the information and
people contactable on it becomes more indespensible. Organisations are
finding increasing pressure to connect in order to fulfil their goals.
However there are persistent security concerns with an Internet
connection.  This workshop will summarise the threats to be
considered, and the possible countermeasures. In particular we will
discuss the use of firewalls to provide perimeter defence around
private networks, by providing a single controlled and monitored point
of connection. We will discuss several practical firewall
configurations: a screening router, a single bastion host, and a
double host scheme. These provide a range of tradeoffs between ease of
design and maintenance, access to service and security.  Some guides
to building these alternatives will be provided.

7 - Introduction to PERL - Tues PM
Frank Crawford, ANSTO

Perl is an interpreted language optimized for scanning arbitrary text
files, extracting information from those text files, and printing
reports based on that information.  It's also a good language for many
system management tasks and has recently become very popular for
implementing CGI scripts that provide advanced functionality in Web
servers.  The language is intended to be practical rather than
beautiful.  It combines some of the best features of C, sed, awk, and
sh, so people familiar with those languages should have little
difficulty with it.

Tuesday 13 February - full day

8 - Introduction to Tcl/Tk (full day) - Tues ALL DAY
Steve Ball, ANU

Tcl and Tk offer a new approach to constructing X applications that is
much simpler and more powerful than alternative approaches.  This
tutorial will give an introduction to Tcl language constructs, syntax
and basic commands. The introduction to Tk will present an overview of
available widgets, geometry managers, advanced widgets, event handling
and other functionality.


The Conference will be held on Wednesday 14th February in ANU at
9am. Registration will be in the Manning Clark Foyer. Morning and
Afternoon Teas and Lunch will all be provided. The program will
include the following presentations:

Andrew Tridgell, ANU

Samba is a free SMB fileserver for unix. It allows a unix box to act
as a file/print server for PCs which use the very common SMB
protocol. Samba is in use at thousands of sites worldwide. In this
talk I'll give a overview of Samba. I'll give a few technical details,
design criteron etc, as well as a few anecdotes. I'll also give a bit
of a description of what I think the future of Samba will be.

IPv6 - The Next Generation
Peter Elford, Cisco Australia

Why does there need to be an IPv6? How is it different from whatever
version of IP we are using now? This talk provides some background to
the requirements for and development of the IPng (Next Generation)
protocol. A brief overview of the features offered by IPv6 will also
be provided.

Government Publishing on the Web:
An Example Management Tool for Large Data Repositories
Bruce McLeod, Approved Systems

This paper discusses some of the data management issues concerned with
the storage of large data repositiories of text.  Normally in Government
there are large existing repositories of data either present as legacy
data on mainframes or as file servers full of word processing
documents.  Without having to go through a large HTML conversion process
and data redundancy headache, the development documented in this paper
describes how data can be: free text searched, dynamically formatted as
HTML, and presented to the user so that documents can delivered by:
FTP, EMAIL, or direct FAX.

Monitoring Network Connection Attempts on a FreeBSD Server
Warren Toomey, ADFA

Tools such as Strobe and SATAN allow both network administrators and
hackers to test vulnerable points in a networked system's security.
This presentation looks at kernel modifications to a FreeBSD server
which monitor and log these sorts of activities. A summary and review
of the last six months of log information will be given for the
well-known ftp/WWW server minnie.

Aegis is Only For Software, Isn't It?
Peter Miller, AGSO

Aegis is a Software Configuration Management system, which provides a
method for managing concurrent development and peer review with strong
auditability. Other systems being managed with Aegis at AGSO are DNS
and the Web. Using Aegis to manage DNS provides a reliable way to
maintain and check DNS tables. The system is peer reviewed, so no
'broken' changes are able to get into the system tables. Using Aegis
to manage the AGSO Web models the production of scientific papers.  In
the normal publication process an author writes a paper and then it is
peer reviewed, the reviewers may return it with comments or approve it
to the publisher.  The publisher in turn may accept it for publication
or return it.  A similar model is available using Aegis when
publishing Web pages; the publication analogy is deliberate since the
work is indeed available to the public.  The 'build' step is used to
resolve server-side includes, check HTML and to generate various
indices. Some Aegis reports are also used, such as the one from which
the 'What's New' page is generated. The provision by Aegis of
individual 'sand pits' greatly facilitates concurrent development of
Web pages and improves productivity.

Plan 9
Chris Vance, ADFA

Plan 9 from Bell labs is the latest in research operating systems from
the organisation which gave us Unix. Plan 9 is a distributed
system. In the most general configuration, it uses three kinds of
components: terminals that sit on users' desks, file servers that
store permanent data, and other servers that provide faster CPUs, user
authentication, and network gateways. These components are connected
by various kinds of networks. Plan 9 is now available on a PC platform
for experimentation and evaluation as will be demonstrated.

Linux Update
Stephen Rothwell, NEC Information Systems Australia

Linux is a freely available Unix-like operating system for several
different hardware platforms.  This talk will present a summary of where
Linux came from, an overview of where Linux is now and an (educated)
guess of where it is going. I will also attempt to give a
rationalisation of why we use (and enjoy) Linux.

The PDP Unix Preservation Society
Warren Toomey, ADFA

Unix is now over 25 years old, having been started by Ken Thompson and
several others at Bell Laboratories in 1969. For most of the 70's,
Unix was developed and used on PDP-11s with 256K of memory or less,
and supporting dozens of users. A PDP Unix Preservation Society has
been started to not only to preserve the source code, binaries,
anecdotes, urban folklore of the era of Unix on PDPs, but also to form
a `user group' of people who are still interested in PDP Unix and/or
who are still running Unix on PDPs, so as to share experiences, ideas,
tips and answers about this old software. The presentation will look
at the features of the PDP Unixes, give some folklore, and hopefully
demonstrate Sixth or Seventh Edition Unix in action.
