Re: WLUG history - Doug Waud's Home Networking slide deck found!

by Doug Mildram

I read the first dozen+ slides ( real good wording/intro I'd say!) ..then ADD-like, surfed later slides and found a minor gem in slide30 so I'll type it back here if I may, just for fun : (Networking) Addressing and Networks (review exam :) What address/addresses represent a network and which a host (assume a netmask of 255.255.255.0) a) 192.168.1.35 b) 192.168.7.12 c) 192.168.3.0 d) 192.168.0.255 e) 192.168.0.0 ANSWER: ( network: c,e ) ( host: a,b ) d) is neither, it is the broadcast address for network e Notice how it is natural to refer to that network by its addr 192.168.0.0 Incidentally, that term "host". It simply means computer. You run into it alot when you are setting up ip addresses. (end of slide 30). ============== dmildram,static> those were the days. Mask? What Mask?

I thought I had been to every WLUG meeting back then. Memories fade. I am trying to remember when I went to Mexico...I am pretty sure I was there several times. At the time I was sure I would remember every detail forever, but now I can't recall what year it was. It might have been 2001. > So I updated the WLUG website's Archive section [1] with the slides: > Home Networking (March 2001) Great job of cyber-archeology! I checked it out. It's 80 slides!! That's not a talk; It's at least four talks. I could not have forgotten all that---must not have been there. It's already proven useful in a way redeems WLUG. After moving ethernet cables around to do jit.sw/WlugMA last Thursday, I discovered I had broken another one of those stupid little plastic latch pins on the end plug. I bought a bag of a dozen at Stark electronics about the time of Doug's talk two decades ago. I am down to just three of them. Stark is long gone; where can I get more? I thought of Google, but I could not remember what the plugs were called. After paging quickly through a few slides, there was the answer! They are called RJ-45 plugs and you can buy them through Amazon. They come in bags of 100, which is excessive, but not too expensive; ($10-15). I suppose I will get a bag. That's more than a liftime supply. In a couple more decades you will be able to pick up about 90 of them _real_ cheap at the estate sale, or free from the dumpster. -- Keith

I remember the talk fondly, with the slides containing many humorous pictures of tin cans and string. The WLUG website had a link to Doug's slide deck, but it was a broken link to http://www.townisp.com/~dougwaud/homenet.htm. I spent hours looking for a backup of the slides on my systems and on the Wayback Machine (archive.org) I even contacted TownISP's support to see if they had a backup of users' old websites, to no avail. So I gave up and never mentioned it at the time. Well guess what...fast forward to today...I was looking for something unrelated and stumbled upon a backup of my long gone Sun Ultra 10 system that ran Aurora Linux (a rebuild of Red Hat/Fedora), and in there I found a copy of the slide deck! So I updated the WLUG website's Archive section [1] with the slides: Home Networking (March 2001) Presented by Doug Waud. Written by Doug Waud, Chuck Anderson, and Stephen Daukas.
