AUUG Canberra Summer Conference 96

Wednesday 14th February, 1996 - Manning Clarke Centre - Australian National University - 9.00am

A conference on UNIX and Open Systems for the Canberra Region brought to you by the Canberra chapter of AUUG Inc.

The Conference was held on Wednesday 14th February in ANU at 9am. Registration was in the Manning Clark Foyer. Morning and Afternoon Teas and Lunch were all 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.
