Setup Inter-VLAN Communication via “Router on a Stick”

Wednesday, March 30th, 2011

This lab demonstrates inter-VLAN communication via the “Router on a Stick” method. To enable inter-VLAN communication, a trunk link is created between a router and switch. Trunk links can carry traffic for multiple VLANS. Trunk links can also be used to span VLANs across multiple switches and allow them to communicate with each other. In general, communication between VLANs must go through a layer 3 device. (more…)


How to sink your company with bugs, poor design, and poor support – SnagIt Case Study

Saturday, March 12th, 2011

TechSmith’s SnagIt is a popular screen/video capture software for Windows and Mac. It does get the job done most of the time, but these days, especially with basic screen and video capture, I expect much better. After having been forced to use this software because of limitations on what I have access to, I am surprised it is as popular as it is. I’m assuming most of those who use it are the “average Joes’” who know about it through word of mouth and its catchy, easy-to-remember name. I have used a number of screen capture utilities and, for Windows, would much rather prefer HyperSnap for screen capture and Camtasia Studio (also developed by TechSmith) for basic video capture . For Linux and Mac, I’d prefer the basic screen capture utilities that come with the OS. Camtasia Studio is also developed by TechSmith and is greatly superior to SnagIt, but it is also more expensive; I have not played with it extensively so cannot comment much more on it.
