Minnie is a 2.4GHz P4 with 768M of memory, 500G of hard disk and is running Ubuntu. It provides anonymous ftp, many mailing lists, a web server and some CGI scripts, and is the prime repository for the Unix Archive. No user accounts are available.

Minnie is fully funded out of my own pocket. Donations, expressions of gratitude and constructive criticisms welcome :-) Minnie is run with minimal housekeeping - I'm a full-time lecturer. Your patience is very much appreciated.

Minnie's History

In mid-1988 I bought a 10MHz XT clone to play with Minix; I was also an avid Goon Show fan. By January 1989, the machine had been christened `Minnie'. At the end of 1989 I took a job at ADFA and bought a 386SX to replace the XT. In May 1991, Minnie (the XT) was brought in to work to become a small FTP server for my Minix and amateur radio interests. Here is the original announcement of the ftp site on Minnie (and cache).

From 1990 to 2000, Minnie's hardware was the hand-me-down equipment from my home PC, running a not-so-recent operating system. In 2000, I bought a new Celeron to break the trend. Here is a table showing Minnie's configuration since 1990. It's interesting to see how the figures have changed.

Period Starting CPU Disk Capacity Memory Net Connection Operating System
Early 1990 10MHz 8088 30M RLL 640K 10Base2 KA9Q NOS
Circa 1992 20MHz 286 80M ESDI 2M 10Base2 JNOS
March 1993 33MHz 386SX 140M ESDI 4M 10Base2 386BSD 0.1
Circa 1994 40MHz 386DX 140M ESDI - 1G IDE 8M 10Base2 FreeBSD 1.1.5.1
Circa 1996 100MHz 486 4G - 16G IDE 16 - 32M 10BaseT FreeBSD 2.2.8, 3.2
May 2000 400MHz Celeron 28G - 40G ATA 64M 100BaseTX FreeBSD 4-STABLE
June 2004 500MHz P3 40G - 60G ATA 192M 100BaseTX FreeBSD 4-STABLE
June 2005 2.4GHz P4 320G ATA 768M 1000BaseTX FreeBSD 5-STABLE
June 2009 2.4GHz P4 500G ATA 768M 1000BaseTX Ubuntu 9.04

The 486DX with FreeBSD was the best, most reliable old box I've ever had. She commonly had uptimes well over 70 days, with a few times over 100 days. The main reason for crashes was power failures; we typically have 2 or 3 a year. On the last day of her service, the 486 pumped out 1.2G of HTTP, 2.2G of FTP and 3.7G of rsync traffic. The system load never rose above 2.5.

Here's a graph of Minnie's main hardware details over time, with dotted lines showing a line of best fit. It seems like Moore's Law works over the given time period.
