Hello friends, I've made this call once before and the response was very positive so I thought I'd do it again. As some of you know, I occasionally teach networking classes at DePaul University in Chicago. What has gone over extremely well in the past is when I've had a real op come talk to the students, even if its just about what they do on a daily basis. If any of you are in or around the Loop in Chicago area on a Tuesday night between September and November of this year and wouldn't mind sharing what you know and/or what you do, I would be forever grateful if you do so with my class. Dinner and drinks before and/or after are on me. I'm not asking for anything polished. If you've presented something recently that you think a computer science undergrad should be able to grasp or even if just have enable, your future ops want you to tell them about it. ...and yes, often times other instructors, and unfortunately the required book, spend an inordinate amount of time talking about classful addressing. So you'll be doing the world a favor and maybe even me, by saying some things I'm not the only one saying to them before they hit the interview circuit. Here's the course home page with links to previous versions of it: <http://condor.depaul.edu/jkristof/tdc375/> Thank you, John
