IT Infrastructure & Security - Fall 2019


(10/22) Change in DMARC! Please adjust the floorplan! Pioneer has just told us that they'll place the dmarc for our warehouse on the outside wall of the network room! Connect the DSL/WAP directly to the POTS circuit provisioned for the DSL. (This will make it easier to avoid any crossed lines.

(10/22) Good question from class: I put the telecomm jacks everywhere they need to be and now when I try to drag a connector from the connection point at the top of my rack the connector wants to jump everywhere else?

It's good that you placed all the telecom jacks for the ethernet ahead of the wiring. That makes it easier to meet the spec for using that symbol, and also for no crossed lines.

It sounds like you didn't lock and shut off the snap and glue for every layer except the Flow Terminal or Power/Comm layer where Visio places Telecomm outlets?

After you've snapped and glued all the telecomm outlets to the walls close to the desk or bench and are ready to draw the bundles of drops, take care to lock the Walls and Building Envelope before placing the connections for drops.

Otherwise, Visio's rather fuzzy logic will try to connect to anything that will accept a connection.

I believe I demo'd in all classes how to fake a rack in the network room using a wall segment with a couple connection points on the top, one for each bundle. Before locking the Building Envelope & Walls layer I deftly, maybe clumsily, selected the wall segment used to fake the rack and used the layers dialog to assign it to the Flow Terminal & Power/Comm layers.

Lock every layer you're not working with and Visio's snap features make connectors easy to drag between connection points, then tug them into a bundle running along a wall or on rafters.

(10/22) The due date for Dlv #2 of the LAN project has been pushed back to Nov 7th at Pranav's request. Please work early and allow time to develop expertise with the tools and make a good bill of details. Never share your files with anybody else, they'll likely submit it as their own and you'll both get an honor violation, has already happened with Dlv #1.

(10/15) Questions from email:

(10/15) I was wondering from your demonstration in class how you were able to fit the picture of the floor layout to be exact on Vizio?

I pulled horizontal guidelines from the 'rulers' at the top and bottom of the page by hovering over their edges to get the double-ended arrow, then dragging a guideline to 20 feet at the bottom and 120 feet at the top to make them 100 feet apart, then stretched the background image by a corner to fit between them, centered the image, put it on a new layer, and locked it. Then I dragged an 'L shaped room' from the shapes template and sized it to fit the outline of the warehouse.

What kind of printer is the 'big color lazer'?

That's a 'floor model' color laser printer that has at least two 11 X 17 paper bins, at least two 8 1/2 X 11 bins, and a binding attachment that will make 8 1/2 X 11 booklets by printing the cover on heavier stock and the pages, then stapling in the middle of the 11 X 17 sheets. Something like one of the Xerox Workcentre or a Cannon Image Runner lasers would work, so would a big Kyocera TASKAlpha. You could google on these, check the images, and then check the specs for those that have lots of paper bins and a binder. I shared an office with one of these some years back, was a $40,000 printer on lease from Cobb Office. Now prices might be hard to find, but they're in the $9000 to $15000 range.

(10/14) Take care to use this semester's LAN Project! Use the link below and make sure you've got the Memo, Floorplan, and Rack diagram for this semester...

(10/14) Points are posted for Quiz #1 plus extra credit for demonstrating a virtualized Mac or PC. About a third of the class scored F or less and that agrees with what I see in class, and it affects me deeply, where there are a _lot_ of students who never take notes or pay attention and many are just plain rude and take some of the joy out of teaching. It's hard to bring any energy to a class half full of inattentive, disinterested students. Many thanks to the 40+ students who earned an A or B and help warm my otherwise mildewed heart...

(10/10) The LAN Project is being introduced in class with some specs and technique today and more next Tuesday. Make sure to use the link below to get to _this_ semester's case study. Dlv #1 for 5 points is due next week at the beginning of class on the 17th, late submits will not be accepted, neither will warehouse outlines that aren't the same shape and size as the floor plan in the Memo from the Boss dated October 10th, 2019, or racks that are printed smaller than the samples. Please work on this project early so you have time to develop skills, get going on the bill of details, get questions answered in class, and don't expect to get much help from me or Pranav at the last minute for either of the deliverables. If we don't cut off tech support we've seen crowds of 30+ students desend on the teaching assistant at the 11th hour, is not good to see...

A well-done LAN project has consistently been one of the most valuable pieces in a portfolio students show a hiring manager. A poorly-done LAN project isn't worth much at all.

(9/10) Quiz #1 on the Computers topic will be Thursday the 19th. Study questions are at the bottom of the Computers card below. Pranav's got a study guide about ready to send out...

(8/29) Get Visio on your computer. We'll be starting on the LAN project in about two weeks and you'll need it.

Virtualize a Mac to run Windows, or Windows to run Kali or other Linux, or suggest another virtualization for approval. 5 bonus points, added after final grades are calculated, will be posted for virtualizing your machine. VMWare's Fusion for a Mac, or VMWare Workstation for Windows are probably the most valuable experience since VMWare has a huge share of the virtualization market. Oracle's VirtualBox is free but doesn't have much commercial market share...
