A Letter from the President

It's been an excellent start to year 2000 for CACTUS, or at least I think so. If you get a chance, take the time to drop a note to programs [at] cactus <dot> org and tell Ray how much we appreciate the programs he's brought us so far. Also, while you're there you might suggest programs you'd like to see, or that you saw with another group that might make sense to bring to CACTUS.

If you've been coming to the meetings, you know that we've tried to vary the fare served a little the last two months. We've tried Papa John's and now Double Dave's pizza. I'll try to find at least one more new one for next month, and I'm open to suggestions. I have to admit, though, that Double Dave's is going to be hard to beat. I think I'd like to stick with pizza, but if you've got another suggestion I'll certainly listen.

The machine family grew by one this month, with my installation of the sparc 10 at Jump.Net. We will be trying very hard to move the services we depend on from the sparc2 at RealTime.Net to either the sparc10 or the linux box at Outer.Net. We hope to be able to rebuild the sparc2 very soon, to clear up some problems we've been having. However...,


We urge every member with data on the sparc2 to copy it to one of the other boxes immediately. If you need help with that please send a request with details to admin [at] cactus <dot> org. We will probably automatically migrate the email related files, but no other users files will be moved without your direct and immediate action.

Thanks, and don't hesitate to email me if you have any comments or suggestions.

March Meeting

This month's program featured be a presentation by the local Austin start-up company, Journyx. Journyx develops innovative web-based productivity enhancing applications--specifically, solutions for tracking time, costs, expenses, and projects. (And yes, it can import Microsoft Project files).

A brief discussion after the meeting by the officers present focused on moving essential services from the Sparc II to the Linux Box and the Sparc 10. Former CACTUS president Jack McKinney has offered to help make the mail transition as easy as possible. For those of you who may not be familiar with our mail system, we're using qmail, a modern robust and secure MTA. Jack is a shaman with qmail and can make it do amazing things. With Jack's help, we look forward to having pizza delivered to future meetings via qmail!

We welcome CACTUS's newest Sponsor, Austin ISP joins Real/Time Communications and Outernet Connection Strategies as special sponsors providing us with our lifelines to the Internet. will be colocating our new Sparc 10 which will soon fully replace our aging Sparc II. The Sparc II has been a constant source of security problems for nearly a year and will be taken down for a complete overhaul or possible return to Sun, which owns it.

The Sparc II has been hosted at Real/Time Communications which has a long and strong relationship with CACTUS. In the early 90s, when the Internet was the province of big universities and corporations and there was no such thing as a public ISP, CACTUS had a connection to the Internet through UT. Membership was in the hundreds and a dialup connection to the Internet came with every membership. Real/Time started out as a CACTUS host,, where subscribers did ftp transfers by ftpmail and email was handled via UUCP! Real/Time grew into one of Austin's first fully connected ISPs and returned the favor to us by providing CACTUS's Internet service, colocating our Sparc II for many years. We look forward to a strong continuing relationship with them.

Our other sponsor providing us with colocation is Outernet Connection Strategies. Outernet colocates our Linux box, Next month I'll tell you about Outernet, which has been providing us with this service for close to a year.

We extend our sincere thanks to Auspex Systems for renewing their membership. Their continuing corporate sponsorship is appreciated.

Auspex Systems, Inc. develops, manufactures, distributes and supports a line of multi-protocol Network Attached Storage (NAS) devices also referred to as network file servers that include specialized software for storing, serving and managing network data. The Company's new NAS products are designed to store, manage and deliver data to network clients with a continual focus on reliability, scalability, UNIX/Windows NT file sharing and price/performance.

The Company also offers three software options that can be purchased with the NS200 NAS product. The first, DataGuard, allows users to continuously access NFS data in the event of a disruption associated with the host operating system. The second product, NetServices 2.0, delivers seamless file sharing between UNIX and Windows NT clients in order to facilitate collaboration and reduce the total cost of ownership relative to replicating data on separate UNIX and Windows NT servers. The third, NDMP TurboReplicator promotes extremely high speed backup of NS2000 storage subsystems to DLT-7000 tape libraries with documented data stream rates in excess of 190GB/Hour, without impacting production network bandwidth.
