This is an extended abstract prepared during July, 2001. It is a work in progress.

This article appeared in the April 2001 issue of the Network Analysis Times. It contains the results of an informal investigation into the distribution of flow sizes during Fall 1999, Spring 2000, and Fall 2000 sample periods. Ostensibly this coverts the period of time during which "file sharing" applications such as Napster, Gnutella, Scour Exchange, and the like, became increasingly popular and generally available.

This is a paper on my FlowScan package which I presented in December 2000 at the LISA 2000 conference in New Orleans. The paper, as published in the conference proceedings, is available here: http://www.usenix.org/events/lisa2000/plonka.html.

This article appeared in the August 2000 issue of Sys Admin. I describe my experience of restoring data from a 4mm DAT tape that had subsequently been partially overwritten.

This document contains information on how institutions can monitor Napster traffic, based upon what we have done at the University of Wisconsin - Madison.

This article appeared in the December '98 issue of Sys Admin. I describe a revision control system that administrators can use to track modifications of configuration files. The code for that article is at http://net.doit.wisc.edu/~plonka/find_revisions.

This article appeared in the Feb. '97 issue of Sys Admin magazine.

My Erdos Number

My Erdős Number is 3.
I co-authored a paper with Amos Ron ("A Signal Analysis of Network Traffic Anomalies", 2002), who collaborated with Charles Kam-tai Chui ("On the convolution of a box spline with a compactly supported distribution: linear independence for the integer translates.", 1991), who collaborated with Paul Erdős ("On changes of signs in infinite series.", 1978).
