When you need to access a server through a security device can be challenging. Mainly because these devices are designed to keep things from getting inside. I have been involved in many network and application migration projects that grind to a halt because the client can’t access a critical application. This is precisely why I recommend clients documenting their applications protocols, servers, port numbers etc. This may sound like a monumental task but doesn’t take that long once you get the hang of it. I just did one for a client that took approximately 30 minutes and was about 5 pages long. In this video I wanted to baseline what ports and protocols this wireless IP webcam uses for its video stream using Wireshark. I ran into an issue with a client that wanted to put all the cameras and security equipment on a firewalled VLAN. After the changes the cameras and other equipment were not reachable. The client was assuming read the rest of this article for free at ; http://www.networkcomputing.com/author-bio.asp?author_id=2332 ... https://www.youtube.com/watch?v=KBf28tNVq6U

tons of info at www.thetechfirm.com I was working with a project team installing over 100 switches across 3 towers which is daunting enough. To top it off, it was active construction site, which means power is not reliable and in some cases, no elevators were available. Me and another contractor’s responsibility was to get as many switches racked and configured within my 3 week period there. The contractor, I was working with was not interested in installing the equipment at all and I appreciated his honesty. I talked him into doing one rack together so he can at least what is involved. Since I was, um, more seasoned ;) I volunteered to rack the remaining switches and he can configure them. Trust me, I got the short end of that stick big time. Racking the switches involved physically retrieving the equipment from the storage room in the basement, transporting it to the relevant floors, unboxing, installing, labelling, discarding the empty boxes and wrapping the equipment with bags to protect against dust. If we had power, the other consultant configured the equipment. If we didn’t have power, we noted it and moved on. The next day the project manager asked me if I would be able to manage since the other consultant would not be in that day. I asked what exactly he was talking about. He thought the two of us were racking the switches on all the floors. I chuckled and explained that one person can do it. The project manager was shocked and said that he spoke to a few network analysts and all of them said it was a two person job. He then asked if I mind showing him exactly how it did it. Unfortunately I’m not up on the new fancy terms to properly title this methodology. Some people call it a lifehack, a hack, but I prefer a tip or trick. What I couldn’t show you in the video is that it doesn’t matter if you need to install one or 5 switches, it the same process. The only difference is with more than one switch, start with the bottom one and use the existing switch as a shelf to support the new switch and work your way up. ... https://www.youtube.com/watch?v=Jm_DRMYlUhI

Performing a Manual Wi-Fi Site Survey for the full article, go to: http://www.networkcomputing.com/wireless-infrastructure/performing-manual-wifi-site-survey/1771773484 I created this video to equally benefit people who have wireless tools as well as people who do not. Why would I say that? If you do not have tools you'll have a methodology to use when performing a manual site survey or basic Wireless troubleshooting. If you do have wireless tools then you can always double check how it is measuring your wireless statistics when you do perform a site survey. The key here is to use your favorite tool with a consistent methodology and if necessary, compare it with your current wireless site survey tool As I mentioned in the video you should figure out ahead of time if you plan on measuring the access point statistics or the end users statistics ... https://www.youtube.com/watch?v=PZAaWZ9BtqA
