But officer.... Google Search It I have recently got two parking tickets (my first).... and thought these signs rather appropriate for the occasion. 6:34:40 AM   []    comment []

Crossover Cable Google Search It It is amazing how you think you understand something and then along comes a obvious piece of knowledge that everybody knows but you had completely missed.  This happened to me yesterday for the umpteenth time.  Generally, whenever I set up a hub/switch I use the up-link port for the cable coming from the wall/network room/another hub/switch.  This past week I was using a switch that someone else had setup and they had not used the up-link port.  This was puzzling to me until I realized that instead they had used a crossover cable from the wall into the hub.  I have used crossover cables to connect two computers directly without a hub but it never occurred to me that the purpose of an up-link port was to essentially switch the wires such that there was a crossover cable between the wall/network room/another hub/switch.  Dahhh! 5:31:08 AM   []    comment []
